Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a high-availability system in which a plurality of server computers cooperate to perform processing, and even if a failure occurs in any one of the server computers, another server computer can take over the processing. High-availability computer system), in particular, a plurality of server computers that provide services to other client computers are linked by a network, and even if a failure occurs in any of the server computers,
The present invention relates to a computer system having a high-availability system design support function suitable for supporting the design of a high-availability system, in which the service interruption time is shortened as much as possible by taking over the service by another server computer.

[0002]

2. Description of the Related Art When a high availability (High Abailability) system (hereinafter, referred to as an HA system) is realized, in addition to the design items in a general system such as a server computer, the number of devices to be used, and a software configuration, what is required In the event of a major failure, you must decide how to take over the service.

A simple method of realizing a conventional HA system is that a fixed hardware configuration and a fixed service takeover procedure for a failure are prepared and used. In general, since it is necessary to flexibly cope with various system forms, a service takeover procedure at the time of a failure has often been described in a script language.

[0004]

The HA system is a system in which reliability is most important. Therefore, if the intended service takeover is not performed or a new malfunction is caused due to a design error due to an actual failure, the HA system is not meaningful.

However, in the prior art in which the operation of the system is described in a script language by a system designer each time, a large number of man-hours are required for the creation thereof, and the possibility that a description error is mixed is high.

Further, there is a problem in the operation management function when operating the HA system implemented in this way. In other words, an HA system operation management function with excellent operability is necessary to accurately know the operating state and failure state of the system, and furthermore, to prevent the system availability from being reduced due to human factors such as operation errors. It is. A fixed-form HA system may have an off-the-shelf operation management function in some cases. However, in a system developed and described in a script language according to the purpose, the operation management function has to be developed exclusively.

The present invention has been made in consideration of the above circumstances, and has as its object the purpose of selecting a file corresponding to a desired configuration and operation and setting system-dependent parameters to obtain a desired high availability (HA). 2.) To enable the system to be designed simply and reliably.

Another object of the present invention is to realize an operation management function by using data created through design work without individually programming.

Still another object of the present invention is to allow any kind of system components and their attributes to be handled in design / operation management by only describing in a template without changing a GUI program. Is to do.

[0010]

SUMMARY OF THE INVENTION The present invention provides an HA for designing the behavior of a high availability system (HA system) in which a plurality of server computers cooperate to perform processing as a scenario (HA scenario) described in a script language. In a computer system having a system design support function, when a scenario receives information separated into a description of a logical operation procedure and a system-specific variable item, a variable item in the information is input according to a user input setting operation. Setting means for setting a parameter to a parameter, and a scenario generating means for generating a scenario by embedding a set value of a variable item for which a parameter is set by the setting means in a corresponding portion in the description of the logical operation procedure. And characterized in that:

In general, it is essential for the reliability of a system to correctly describe a scenario (or a script) that is a program that defines the operation of an HA system, but it requires experience-based skill and is difficult. . However, some HA systems have a typical hardware configuration and a software configuration, and the only difference between them is a system-specific parameter such as a network address.

Therefore, as described above, the description of the logical operation procedure and the variable item which is a parameter setting item unique to the system are separated, and the parameter setting for the variable item is performed.
By embedding the variable items that have been set in the description of the logical operation procedure, a target HA scenario is generated. By using a logical operation that is a difficult part of scenario generation, an existing one is used. Since only simple parameter settings are required, scenario generation can be performed easily and reliably.

In particular, a set of a separated and extracted description of a logical operation procedure and a system-dependent variable item is stored in a file and is used as a template for generating an HA scenario (HA scenario template). Then
While using the same template, it is easy to return to the beginning of the value setting for the template and reset it again, or to repeatedly apply the template to the development of a plurality of different HA systems.

The description of the logical operation procedure and the variable items dependent on the system are stored in separate files, that is, in the first file.
File (frame file) and a second file (slot file).
If it is used as an HA scenario template for creating the scenario A, only the second file is operated in the parameter setting, and the variable items (parameters set in the second file) set in the second file are set in the first file. Just embed it in the description of the logical operation procedure in
A scenario can be generated. Also, the file separation facilitates file analysis at the time of setting. In addition, since only the set second file needs to be referred to as system-specific information, maintenance of the system is facilitated.

Further, a plurality of HA scenario templates (consisting of a set of first and second files) are prepared according to the hardware configuration of the HA system and logical operations, and a user (designer) If the configuration is such that an HA scenario template that matches the logical operation of the target HA system can be selected, the development of various HA systems having different device configurations and logical operations can be supported.

Here, if various system components including various hardware components and various software components are defined as variable items in the second file, a template for an HA system including arbitrary types of components is provided. Can be created.

Further, if a property, which is a system-dependent attribute of each system component, is defined as a variable item in the second file, a template can be generally expressed, and any type of component which is handled differently can be used. For, detailed parameters required at the time of operation can be defined.

If a connection (connection property), which is an attribute determined for each system component corresponding to the server computer, is defined as a variable item in the second file, a template is generally expressed. In addition, it is possible to define detailed parameters required at the time of operation for arbitrary types of components that are handled differently. Further, the expression of the relationship between the service and other components can be simplified. Further, since the server-dependent information is grouped, it is not necessary to divide the description for each server on the logical operation description side.

Further, if a method, which is a process executed to affect the operation or state of each system component, is defined as a variable item in the second file, the template can be generally expressed and , For any type of component that is handled differently,
Any kind of operation and its contents can be defined.

Further, an arbitrary procedure of the service which is a unit of the function provided to the user by the system is defined by a method to be called by the procedure and a calling order of the method, and the method to be called is defined by the second method. If it is defined as a variable item in the file, it will be possible to perform various operations on the services represented by any type of components, their properties, their connections, and their methods, which were previously definable. HA system realizing means with high reliability can be provided.

In the second file, if information of a value type and a value range to be set in the variable item is described in correspondence with each variable item in the file, the second file When setting a parameter to a variable item in a file, it is possible to detect an error in the setting value of the variable item according to the type and range information. In this case, the configuration may be such that the user is notified that an incorrect value has been set, and furthermore, the content (type) of the error. If an implicit value is described for each variable item, the setting can be omitted.

In a system in which a plurality of templates are prepared, for each of the plurality of templates, template information including explanatory information indicating a system configuration described in the template and a deliberate operation is recorded. Third file (index file)
Is prepared, and based on the third file, the selection means displays a template list screen including a display item list of explanatory information indicating a system configuration and a deliberate operation of each template, and The configuration may be such that information on a template that can be selected by a user operation is provided.
In this case, the user can use (select) a template list screen (graphical user interface screen,
In other words, by listing the GU @ screen, a template that matches the target system can be easily selected.

In addition, based on the third file, a list of all system components described in a plurality of templates is displayed by the selection means, and a user-operated component of a user-specified component is displayed. Based on the template information corresponding to the template that matches the system configuration condition indicated by the number of elements of each received component, a display item list of explanatory information indicating a deliberate operation is received. A template list screen may be displayed to provide information on templates that can be selected by a user operation. In this case, the template list does not contain the display items of all templates,
Since only the display items of the template that match the conditions of the system configuration intended by the user, that is, the display items of the configuration of the user's interest, are displayed, the template can be selected more easily.

Further, the respective template information in the third file is provided with information for specifying a corresponding template, and the selecting means holds the information in association with each display item in the template list screen. With such a configuration, the user can select and specify a target template (a display item corresponding to the template) on the template list screen without being aware of the information for specifying the template. A template corresponding to a specified display item can be easily specified.
Here, as the information for specifying the template, the file names of the first and second files constituting the template may be used.

When setting parameters by the setting means in accordance with a user operation, the hardware configuration and software configuration of the HA system to be designed, based on the description of the second file to be set, It is preferable to guide the user's input operation to the variable items to be set in relation to the above on a hierarchical GUI screen. Here, input of items that need to be set is guided based on the second file, and the layout of the input screen is determined. When the user selects a screen according to the menu screen, it is possible to determine a setting screen for variable items and to guide the user to a setting screen having unset items. These setting screens can be flexibly configured according to the degree of freedom in describing the template.

The setting of the variable items by the setting means is completed, or the second file in the process of setting the variable items is replaced with a new second file different from the second file constituting the original template. If the configuration is such that the second file is saved, the saved second file (variable item is already set or in the process of being set) is read again, and the original second file is always kept in the initial state. Reset or additional settings can be made. As a result, even if the parameter setting work is interrupted, it is possible to restart the work at a desired time without wasting the previous setting work. It is also possible to do. In addition, as a storage mode of the second file, a first storage method for storing the second file after the parameter setting as another new second file according to the user's specification, or a template is selected, and the template is selected. Second in
(That is, the second file in the initial state) is copied to another new second file, and a second storage method of setting parameters for the copied file is applicable. In the second storage method, parameter resetting,
Alternatively, when an additional setting is made, the copy file is overwritten and saved, so that a new file is not generated carelessly, which is suitable for version management.

The setting means and the scenario generating means search the stored second file for an unset variable item for which no parameter setting has been performed, and determine the existence and location of the unset variable item. It is good to have the function of presenting. Here, the setting means searches for unset variable items in response to, for example, a user's instruction, and the scenario setting means makes the first file forming a pair with the stored second file and the second file. When a scenario is generated based on the above, it is preferable to automatically search for unset variable items.

In the second file, the second file
The first file that constitutes the template together with the file
It is preferable to apply a data structure in which the file name of the file or the template name of the template is recorded as a fixed item of the second file. In this case, the second
Parameters are set for the variable items in the file
Even when the fixed item is saved as a new second file, the information (the file name or template name) of the fixed item is retained, so that the first file forming a pair with the second file is determined from the information. Template information necessary for scenario generation can be obtained without easily specifying the first file and without duplicating the first file.

Further, a unique identifier is added to each variable item in the second file, and the logical operation procedure stored in the first file paired with the second file is described. If the same identifier is also added to the corresponding variable item in the description, the scenario generation means makes the logical setting stored in the first file paired with the second file in which the parameter is set. When each variable item is searched from the description of the operation procedure, a corresponding variable item in the second file in which a value to be embedded in the variable item is set can be easily searched.

In addition, in the second file, the high-availability system is used so that it can be used for operation management of a high-availability system together with parameter setting values for each variable item in the second file. If you want to have operation management information for monitoring and operating the operating status of the system,
Information set at the time of system design, such as addresses, can be obtained from design information in the same second file (set to variable items by the user). Therefore, such information is defined and retained in the operation management information redundantly. You don't have to. In addition, since it is not necessary for the operation manager included in the HA scenario to analyze unnecessary information (information derived from the first file), necessary minimum information can be obtained efficiently.

Also, the operation management information in the second file is, for each system component, monitoring item information of a logical structure common to the design information indicating items to be monitored in the operation management of the component, And the above-mentioned design information indicating the items to be operated and the operation item information of a common logical structure, and as a system state, a function of monitoring and displaying the state of each component is provided. If a function to perform operations on individual components is provided, hardware components and software components can be displayed using the same GUI program and the same display format for system design and system operation management. Can be displayed. Here, when the first file is set and when the operation of the system that operates based on the scenario generated by the first file is performed, the overall configuration of the system and the method of tracing the information of each device are the same. Many programs and programs for system operation management can be shared, and program creation and maintenance can be simplified. The operation management information can be arbitrarily provided depending on how to write a template.

The display position of each monitoring item and each operation item on the GUI screen at the time of system operation management and the display position of each variable item on the GUI screen at the time of system design support are both of the second position. If it is determined according to the classification system of the items described in the second file, it is possible to flexibly cope with any kind of device, attribute, system status value, and the like described in the second file. Here, a one-dimensional or two-dimensional tabular layout is automatically set for each of the configuration parameters at the time of design, the state values to be displayed at the time of operation, and the operations to be received at the time of operation, depending on whether or not they depend on the server. It is also possible to make a decision. Also, any type of component can be handled flexibly without modifying the GUI program only by writing the template.

Also, H operates according to a scenario generated based on the second file in which parameters have been set.
In the operation management of the A system, the operating status received from the server computer of the HA system is displayed on the GUI screen of the monitoring item using the second file in which the parameters are set, which is the basis of the scenario, and It is preferable that an operation instruction from the user given through the GUI screen of each of the operation items is transmitted to the server computer. Here, information on the status display / operation defined in the second file is also included in the HA scenario. That is,
The operation management computer that has read the second file and the server computer that has read the scenario have common information on the state to be displayed and the state to be operated. As a result, the operation management computer can receive the necessary status information from the server computer, and the server computer can correctly operate the target component according to the operation instruction from the operation management computer. .

The description about the design information 153 has a hierarchical logical structure as shown in the figure.

Each design information 153 for each component has a corresponding component type and element name 153a. The types of components are typically hardware devices such as shared disks and LANs, but are not specified in advance. That is, it can be flexibly added / deleted by the description of the template 13. Also, software elements such as application processes and more macro services are similarly expressed as constituent elements.

The element names forming a pair with the types (element types) of the constituent elements are those set by the user for the corresponding constituent elements, that is, the items for which values are to be set (variable items). In the item of the element name, a temporary identification number (for a disk, disk 1, disk 2, etc.) is added in advance. This number is assigned, for example, continuously so that all elements of the same type do not overlap.

In each design information 153, variable items to be set in the HA system design are classified by keywords of property, connection, method, and call, and are respectively property information 153b, connection information 153c, method information 153d, and call information. Information 1

For example, forcible reservation or release of a shared disk. The call information 153e is meaningful only for service-type components, and is used for each procedure such as starting execution of a service (a unit of a function provided by a system to a user) and stopping execution of a service (that is, starting / stopping a service). It is possible to set in a sequence what operation methods are to be called for various constituent elements and in what order (call of this method is called a call).

FIG. 5 shows the data structure of the HA system operation management information 154 in the slot file 15. This HA
The system operation management information 154 includes operation management information 155 for each component of the HA system. The description about the operation management information 155 also has a hierarchical logical structure like the design information 153.

Each operation management information 155 has a type of element and an element name 156 corresponding thereto, monitoring item information 157 indicating a status item to be monitored in operation management of the corresponding element, and an item to be operated. Operation item information 15 shown
Have eight. The monitoring item information 157 includes the property information 15
7a and description items classified by connection information 157b, and the operation item information 158 similarly includes description items classified by property information 158a and connection information 158b. Property information 157a or 15

In 58b, a monitoring status item or an operation item defined by the correspondence between the corresponding component and the server computer 30 is defined. In the operation management information 155, unlike the design information 153, all fixed items are defined.

Referring back to FIG. 1, the operation of the system in FIG. 1 is divided into two operations, namely, the design of the HA system by the HA system design support computer 10 and the operation management by the HA system operation management computer 20 when the HA system is operating. Can be broadly divided.

HA in HA System Design Support Computer 10
The operation of the system design support is roughly as follows.

A user (designer) who designs an HA system from an initial state firstly has an HA system design support computer 1.
0 of the HA system design support unit 11 and instructs to select one of the HA scenario templates 13 that is suitable for the target system.

HA system design support unit 11 receiving instructions
Reads the slot file 15 in the instructed HA scenario template 13, and reads G according to the user operation.
While displaying a UI (Graphical User Interface) screen, the user is guided to input a value for a variable item defined in the slot file 15. The result of the setting is saved (in a storage means such as a hard disk device) as the set slot file 17. Here, while only some of the variable items are being set, the setting may be saved as the slot file 17 being set. In this case, the next time the design work is performed, reading of the saved (in the middle of setting) slot file 17 instead of the slot file 15 in the HA scenario template 13, that is, the initial slot file 15, is performed by the HA system design support. By instructing the unit 11, the setting operation can be continued.

When all the settings are completed, the HA system design support unit 11 combines the contents of the set slot file 17 with the slot file 15 (which is the initial file of the slot file 17) to form the HA scenario template 13. Is generated in combination with the contents of the frame file 14 that forms the completed HA scenario 18, that is, an HA scenario 18 in which the behavior of the HA system is described as a program in a script language.

On the other hand, the operation of the HA system operation management function in the HA system operation management computer 20 is roughly as follows.

Prior to the start of operation of the system, the user (system administrator) transfers the slot file 17 to the HA system operation management computer 20 and the HA scenario 18 to all server computers 30 in the system, for example, a LAN.
It is necessary to perform an operation for copying each of them via 40. Here, the copy of the slot file 17 in the HA system operation management computer 20 is called a slot file 24, and the HA scenario 1 in the server computer 30 is copied.
8 is called HA scenario 32. In addition, a recording medium (for example, a floppy disk, a magneto-optical disk, etc.) storing the slot file 17 and a recording medium storing the HA scenario 18 are respectively used, and are directly mounted on the HA system operation management computer 20 and the server computer 30. Then, the data may be read by the computer.
In this case, the HA system design support computer 10 is not necessarily the HA system operation management computer 20 and the server computer 30
May not be able to communicate with each other and need not be connected to the LAN 40.

The server computer 30 has an HA kernel 31. The HA kernel 31 is realized by system management software (daemon program) for operating in the background of the system and managing the operation of various user application programs, and a CPU (not shown) for executing the software. so,
The system is operated according to the HA scenario 32.

On the other hand, the HA system operation management computer 20
Has an HA system operation management unit 21 for managing the operation of the HA system. The HA system operation management unit 21 is realized by an HA system operation management program (hereinafter, referred to as an ADM program) 22 and a CPU (not shown) that executes the ADM program 22. The ADM program 22 is provided by a recording medium, for example, a CD-ROM 23. That is, the ADM program 22 is stored in the CD-ROM 23 in advance, and the CD-ROM 23 is stored in the C-ROM of the computer 20.
By being loaded into a D-ROM device and read into the computer 20, it is used, for example, by loading it into a hard disk device in the computer 20. Note that, instead of the CD-ROM 23, another recording medium such as a floppy disk, a DVD-ROM, or an optical magnetic disk can be used. The ADM program 22 can be downloaded via a communication medium such as the LAN 40. In addition, the DSG program 12, H
A scenario template 13, index file 1
6 and the ADM program 22 may be stored, or the DSG program 12 and the ADM program 22, the HA scenario template 13 and the index file 16 may be stored in separate recording media. . Alternatively, only one of the set of the DSG program 12 and the ADM program 22 and the set of the HA scenario template 13 and the index file 16 may be downloaded via a communication medium such as the LAN 40.

The HA system operation management section 21 acquires the operating state of the system from the server computer 30 according to the slot file 24, and displays the acquired information on the GUI screen according to the slot file 24. The HA system operation management unit 21 displays a GUI screen for an operation management operation executable by the user according to the slot file 24, and notifies the server computer 30 when the user instructs the operation.

Next, the HA in the system having the above configuration will be described.
Generation of the scenario 18 will be described with reference to FIG.

First, the HA system design support unit 11 in the HA system design support computer 10
11, a template setting unit 112, and an HA scenario generation unit 113.

The template selection unit 111 refers to the index file 16 and, based on the HA system configuration information 161 and the system operation description 162 (see FIG. 2) included in each template information 160 in the file 16, The features (description of the hardware configuration and its logical operation) of the HA system indicated by the scenario template 13 are presented on a screen, and the user (designer) can obtain a desired H system.
The system A is selected and instructed. Each template information 16
0 indicates the file names 163, 1 of both the frame file 14 and the slot file 15 constituting the corresponding HA scenario template 13, as shown in FIG.
64 (this is equivalent to including the file name of the corresponding HA scenario template 13). Then, the template selecting unit 111 selects the HA scenario template 13 corresponding to the HA system having the feature selected and instructed by the user, and notifies the template setting unit 112 of the slot file name of the slot file 15 of the template 13.

The template setting unit 112 reads the slot file 15 of the slot file name notified from the template selection unit 111 from the corresponding HA scenario template 13, and displays the GUI screen corresponding to the user operation as described above. , Slot file 15
Induce the input setting of the value for the variable item defined in. The result of the setting is saved (in a storage means such as a hard disk device) as the set slot file 17. Even if the same slot file 15 is used, if the user performs a different setting operation for another HA system, a slot file 17 'different from the slot file 17 will be obtained.

When the HA scenario generation unit 113 obtains the slot file 17 (17 ') in which all the settings have been completed, the HA scenario generation unit 113 forms an HA with the slot file 15 which is the original file of the slot file 17 (17'). Frame file 14 forming scenario template 13
Is read, and in the variable items of the frame file 14,
An embedding process 114 for embedding the setting contents of the corresponding variable items that have been set in the slot file 17 (17 ').
By performing (114 '), the completed HA scenario 1
8 (18 '), that is, an HA scenario 1 in which the behavior of the HA system is described as a program in a script language
8 is generated.

As described above, in the present embodiment, the HA scenario includes a description of the logical operation procedure (the frame file 14 having the file), and the variable item (the slot file 15 having the parameter setting item) unique to the system. By setting the parameters to the variable items and embedding the set variable items in the description of the logical operation procedure, the desired HA scenario 18 can be easily generated.

In particular, in the present embodiment, a set of a separated and extracted logical operation procedure description and a system-dependent variable item is stored in a file, and is used as an HA scenario template for creating an HA scenario. Since the same template 13 is used, it is possible to return to the beginning of the value setting for the template 13 and reset it again while using the same template 13, or to repeatedly apply the template 13 to the development of a plurality of different HA systems. It becomes easy to do.

In this embodiment, the description of the logical operation procedure and the system-dependent variable items are stored in separate files, that is, the frame file 14 and the slot file 15. The set is used as an HA scenario template 13 for creating an HA scenario, and only the slot file 15 is operated for parameter setting, and the slot file 1 that has been set is set.
5, that is, by embedding the variable items (parameters set in) in the slot file 17 in the description of the logical operation procedure in the frame file 14, the HA scenario 18 can be generated extremely easily. Also, the file separation facilitates file analysis at the time of setting. In addition, as the system-specific information, the set slot file 17
Since only reference is required, maintenance of the system is facilitated.

Further, in the present embodiment, a plurality of HA scenario templates 13 are prepared in accordance with the hardware configuration of the HA system and the logical operation, and the user (designer) selects the HA scenario template 13 from among them. By selecting the HA scenario template 13 that matches the logical operation, various H configurations with different device configurations and logical operations can be selected.
We can support the development of the A system.

Further, in the present embodiment, for each of the HA scenario templates 13, as shown in FIG. 2, two files constituting the template 13, ie, the file names 163 and 163 of the frame file 14 and the slot file 15, respectively. A set of 164, information (HA system configuration information) 161 indicating the configuration of the system described in the template 13 and a system operation description 162 that is information for explaining a logical operation is recorded as template information 160. Index file 1
6 is provided, and the user (designer) can easily select a desired template by guiding the user to select an HA scenario template based on the index file 16.

In this embodiment, as shown in FIG. 7, the component information included in the design information 153 for each component constituting the HA system design information 152 of the slot file 15 in the HA scenario template 13 is shown. The type and the element name 153a are variable items (variable parameter setting target items) in the slot file 15. That is, the element names of the various system components 33 including the hardware components such as the server computer 30 and the shared device, and the software components such as the application processes and the services are set in the slot file 15 in the variable items to be set at the time of the system design. And Therefore, it is possible to create the HA scenario template 13 for a system including any type of components. In addition, by defining the element names of the respective system components as variable items, as shown in FIG.
It is possible to define each element 33 that is the target of the operation according to the HA scenario 32 by the HA kernel 31 in the inside.

In the present embodiment, as shown in FIG. 8, the corresponding configuration information included in the design information 153 for each component constituting the HA system design information 152 of the slot file 15 in the HA scenario template 13 A property (property information 153b) indicating a system-dependent attribute of the element is also one of the variable items in the slot file 15. As described above, by defining an arbitrary attribute depending on the system for each system component in the variable item, as shown in FIG. 8, the HA kernel in the server computer 30 can be used for an arbitrary type of element 33 which is handled differently. It becomes possible to define the detailed parameters required at the time of the operation according to the HA scenario 32 by 31.

Further, in the present embodiment, as shown in FIG. 9, the corresponding configuration information included in the design information 153 of each component constituting the HA system design information 152 of the slot file 15 in the HA scenario template 13 The connection (connection property, connection information 153c), which is an attribute of the element determined corresponding to the server computer 30, is one of the variable items to be set at the time of system design. In this way, by defining server-dependent attributes in variable items for each system component, as shown in FIG. 9, for each type of element 33 handled differently by each server computer 30, each server computer 30 It is possible to define detailed parameters required for an operation according to the HA scenario 32 by the HA kernel 31 in the inside. Here, since the server-dependent information is grouped, the description of the logical operation (frame file 1) is described.
On the fourth side), there is no need to divide the description for each server computer 30.

In this embodiment, as shown in FIG. 10, the corresponding configuration information included in the design information 153 for each component constituting the HA system design information 152 of the slot file 15 in the HA scenario template 13 is shown. The method of the element (method information 153d), that is, the process executed to affect the operation or state of the component is one of the variable items to be set when designing the system. Thereby, as shown in FIG. 10, the contents of the operations of the method processes 34-1, 34-2,... Which are read by the HA kernel 31 in the server computer 30 and operate on the same system component 33, are defined. It becomes possible.

Further, in the present embodiment, as shown in FIG. 11, the element type included in the HA system design information 152 of the slot file 15 in the HA scenario template 13 is a call of the design information 153 of the component of the service 35. The (call information 153e) is a variable item for setting a method to be called in each step of the execution start process and the execution stop process of the service 35. Here, any procedure (such as "starting" or "stopping" a service, or H
A), which is often prepared in the A system, is defined by the methods to be called by the procedure and the calling order of the methods. This allows any kind of component, their properties, their connections,
In addition, various operations of the service expressed by these methods can be performed, and a highly versatile HA system realizing means can be provided.

In the present embodiment, as shown in FIG. 12, each variable item 120 defined in the slot file 15 (to be set at the time of system design) has a value type 121 to be set. A value range 122 has been added. Further, an implicit value (default value) 123 is also added. The type 121 indicates an integer type, a character string type, an IP (Internet Protocol) address type, or the like. The range 122 is given by a maximum value / minimum value, a selectable candidate value, and the like.

As described above, for each variable item 120, the type 12
Having the information of 1 and the range 122 enables detection and notification of an incorrect setting as described later. Also, the implicit value 12
By having 3, the setting can be omitted.

Next, a GUI function of the HA system design support unit 11 of the HA system design support computer 10 in FIG. 1 for selecting the HA scenario template 13 using the index file 16 will be described with reference to FIG. explain.

First, in order for the user to design the HA system from the initial state, the HA system design support computer 10
It is assumed that the HA system design support unit 11 in the inside has been started. In this case, the template selection unit 111 in the HA system design support unit 11 reads the index file 16 (step 131), and reads the HA system configuration information 161 and the system operation description 162 (each included in each template information 160 in the file 16). Based on the HA scenario template 13, a template list screen 132 is displayed based on the hardware configuration, which is a feature of the HA system indicated by each HA scenario template 13, and display items in which explanatory information on the logical operation is set (step S 2). 133). Here, the template selection unit 111 selects the template list screen 1
32, the file name (slot file name) of the slot file 15 in the HA scenario template 13 corresponding to each display item is internally stored.

The user (designer) selects the H to be designed from the template list screen 132.
A display item selection designation 134 in which information matching the system configuration and the logical operation of the A system is set is performed by a mouse operation or the like.

Then, the template selection unit 111 receives the selection designation 134 by the user (step 1).
35). Then, the template selecting unit 111 stores the template information 1 in the index file 16 internally stored in correspondence with the received user-specified display item.
Then, the template setting unit 112 is notified of the slot file name 164 included in the file 60 (step 136). This is equivalent to selectively notifying (the template name of) the HA scenario template 13 having the slot file 15 indicated by the slot file name 164.

In response, template setting unit 112
Reads the slot file 15 having the file name notified from the template selection unit 111, and displays the GUI file corresponding to the user's operation while displaying the slot file 1
The user is guided to input values for the variable items defined in step 5 (step 137).

As described above, in the present embodiment, the template list screen 13 based on the index file 16
By displaying No. 2, the user (designer) can select the HA scenario template 13 suitable for the HA system that he is designing. Moreover, the user does not need to be aware of the file name of the HA scenario template 13 (and the file name of the slot file 15 in the HA scenario template 13). However, in the present embodiment, the template list screen 132 displays all the HA scenario templates 13 prepared in the system.
Is displayed, it takes some time before the user (designer) searches for the target template information, that is, selects the HA scenario template 13.

Therefore, another embodiment of the GUI function of the HA system design support unit 11 that allows the HA scenario template 13 to be easily selected will be described with reference to FIG.

The template selection unit 111 in the HA system design support unit 11 first reads the index file 16 (step 140), and HA system configuration information 161 included in each template information 160 in the file 16 (see FIG. 2). , All system components are extracted, and an element number setting screen 141 having an element number input field is displayed for each of the extracted components (step 142).

The user (designer) sequentially selects the corresponding element number input fields on the element number setting screen 141 for all the constituent elements of the HA system (target HA system) that he / she is designing, and each time the input fields are selected. Then, the number of elements required to realize the target HA system is set.

The template selection unit 111 determines that the user
Each time the number of elements is set in one of the input fields, the set number of elements is input (step 143), and it is checked whether the number of input elements for the corresponding element is appropriate (step 144). The check of the number of input elements is performed by referring to the HA system configuration information 161 of each template information 160 in the index file 16, and by selecting the minimum element from the number of elements of the corresponding elements of the HA system indicated by the information 161. This is performed by obtaining the number and the maximum number of elements, and checking whether or not the number of input elements is within the range between the minimum number of elements and the maximum number of elements. Each HA scenario template 1 is stored in the index file 16.
It is also possible to previously store the information on the minimum and maximum values of the number of elements for each component of the HA system indicated by 3, and in this case, the check in step 144 can be performed at high speed.

When the number of input elements is within the above range, template selecting section 111 accepts the number of elements,
If the number is outside the above range, the number of elements is rejected, and the user is requested to re-enter the number of elements in the corresponding input field.

When the user finishes inputting the number of elements for all the constituent elements of the target HA system selected from the number-of-elements setting screen 141, the HA system design support unit 11 (the template selection unit 111 in the HA system design support unit 11) enters the information. To the effect. Then, the template selection unit 111 reads the index file 16 and only the template information 160 having the HA system configuration information 161 that matches the configuration (elements and the number of elements) of the target HA system specified by the user on the element number setting screen 141 Are all selected (step 145). Then, the template selecting unit 111 executes the system operation description 16 in the selected template information 160.
2 and the corresponding HA scenario template 13
Is displayed, a template selection screen 146 including a list of display items in which the explanation information of the logical operation of the HA system is set, that is, a list of information indicating templates corresponding to the system configuration of interest to the user is displayed ( Step 147). Here, the template selection unit 111
Holds the file name (slot file name) of the slot file 15 in the HA scenario template 13 corresponding to each display item on the template selection screen 146.

The user (designer) selects and designates, from the template selection screen 146, a display item in which operation explanation information matching the logical operation of the target HA system is set. Then, the template selection unit 111 accepts the selection designation by the user (Step 14).
8). Then, similarly to step 136 in FIG. 13, the template selection unit 111 is included in the template information 160 in the index file 16 which is internally stored corresponding to the display item of the received user-specified operation explanation information. The slot file name 164 is notified to the template setting unit 112 (step 149). Subsequent operations are the same as in step 137 described above.

Next, the GUI function for setting variable items of the HA system design support unit 11 of the HA system design support computer 10 in FIG. 1 will be described with reference to FIGS.

When the template setting unit 112 in the HA system design support unit 11 is notified of the file name (slot file name 164) of the slot file 15 of the HA scenario template 13 selected and specified by the user from the template selection unit 111, The slot file 15 having the file name is read from the corresponding HA scenario template 13.

Based on the description of the read slot file 15, that is, the slot file 15 of the HA scenario template 13 selected by the user, the template setting unit 112 determines the hardware configuration and software configuration of the HA system to be designed, Is guided (guided) by the user as to the input operation to the variable items to be set in relation to the above.

First, the template setting section 112 determines the element type and the element name 153a, which are the information of the highest hierarchy of the design information 153 for each element constituting the HA system design information 152 of the slot file 15, and determines the element type. Are extracted, and a setting target element type selection menu screen G1 which is a list of the element types is displayed.

Here, when the user selects a desired element type from the screen G1 by mouse operation or the like, the template setting unit 1
Reference numeral 12 denotes an element which forms a pair with the selected element type, the type of element and the element name 1 in the design information 153 for each element.
All are extracted based on 53a, and an element selection menu screen G2 which is a list of the elements is displayed.

Here, when the user selects a desired element from the screen G2 by mouse operation or the like, the template setting section 11
Reference numeral 2 includes four items of “name” (element name), “property”, “connection”, and “call” for selecting a variable item (setting item) to be parameter-set for the selected element. The setting item selection screen G3 is displayed.

When the item “name” is selected from the screen G3, the template setting section 112 displays a name setting screen G4 for setting the name of the corresponding element (element name, object name), and displays the item “ When "property" is selected, a property setting screen G5 for setting the property of the corresponding element is displayed. Where the property is
Since the attribute is a system-dependent attribute of the corresponding element, that is, an attribute unique to the element, the property setting field of the property setting screen G5 is a one-dimensional table based on the property information 153b in the design information 153 for the element. Displayed in a formatted layout.

The template setting section 112 sets the screen G
When the item “connection” is selected from 3, the connection setting screen G6 for setting the connection of the corresponding element (attribute determined corresponding to the server computer 30) is displayed. Here, since the connection is an attribute that depends on the server computer 30, the connection setting field of the connection setting screen G6 is a two-dimensional connection determined in combination with each server computer 30 based on the connection information 153c for the corresponding element. Is displayed in a tabular layout. Here, the type of connection is arranged on the vertical axis of the table in the screen G6, and the server computer 30 is arranged on the horizontal axis. The layout of this screen G6 is
It does not depend on specific specific components, but is uniquely determined from the description of the slot file 15. This means that the element type selection menu screen G1,
In addition to the element selection menu screen G2, name setting screen G4, property setting screen G5, a procedure setting screen G described below
7, the same applies to the element selection screen G8 and the method selection screen G9. Therefore, when designing an HA system including new components and attributes, it is only necessary to rewrite the HA scenario template 13, and there is no need to change the DSG program 12.

Further, the template setting section 112 sets the screen G
When the item “call” is selected from the item 3, the corresponding element (here, a service, that is, a service type is selected as an element type on the screen G <b> 1 and a target service is selected as an element on the screen G <b> 2) A procedure setting screen G7 for setting a method (procedure) to be called in each step of the execution start processing and the execution stop processing is displayed. In this case, an element selection screen G8 for selecting an element to be operated by the target service is displayed. When the user selects a desired element from the screen G8, the screen includes a list of methods for operating the element. The method selection screen G9 is displayed. The list of the methods on the screen G9 is the method information 15 of the design information 153 in the slot file 15 for the element selected from the screen G8.
Extracted from 3d. The method selected from the method selection screen G9 is set in the description column of the “call” sequence on the procedure setting screen G7. The screen G7 is provided with function buttons 170 such as “insert”, “add”, “delete”, and “replace” so that editing can be performed on the description column of the “call” sequence.

As described above, in the present embodiment, the GUI function provided by the template setting unit 112 in the HA system design support unit 11 allows the design object to be designed based on the description of the slot file 15 of the HA scenario template 13 selected by the user. In this HA system, the hardware configuration, the software configuration, and the user's input operation on the variable items to be set in relation to the hardware configuration and the software configuration can be efficiently guided by the hierarchical menu screen (GUI screen).

As described above, based on the slot file 15 of the HA scenario template 13 specified by the user, the parameters are set for each variable item in the file 15.

Next, the storage of the slot file 15 in which the parameters are set for the variable items will be described with reference to FIG.
This will be described with reference to FIG.

Now, as shown in FIG. 18A, after the template setting unit 112 reads 180 the slot file 15 of the HA scenario template 13 specified by the user, the hardware configuration of the HA system to be designed is , The software configuration, and the user's input operation to the variable items to be set in connection with them are shown in FIGS.
It is assumed that the parameter setting 181 for each variable item in the slot file 15 has been completed as a result of guidance using the GUI screens (screens G1 to G9) as shown in FIG. In this case, the template setting unit 112 stores the slot file (15) in which the setting of the variable items has been completed in a file different from the slot file 15 constituting the original HA scenario template 13 according to the user's designation. A save process 182 for saving the file 17 is performed. In addition, even when the variable item is being set, the slot file (15) which is being set is designated by the user.
Can be saved as a new slot file 17.

As described above, the slot file (15) which has been set or is being set for the variable item is transferred to the original HA.
By saving as a new slot file 17 different from the slot file 15 in the scenario template 13, the slot file 15 can always be kept in the initial state. When the next design work is performed, the HA system design support unit 11 reads the slot file 15 in the HA scenario template 13, that is, the saved slot file 17 (in the middle of setting) instead of the initial slot file 15. By giving the instruction, the setting work can be continued (new setting for an unset variable item) or the setting work can be redone (change or correction of the set value). In this case, the slot file 17 is reloaded / saved 18
3 will be performed.

In addition, the slot file 17 in which the variable items have been set by resuming the setting operation can be stored as another new slot file.
However, if such an operation is repeated by many designers, various versions of the slot file 17 will be generated, which may make version management difficult. Therefore, a method of storing a slot file that does not allow the generation of a new slot file from the slot file 17 will be described.

First, the HA system design support section 11 includes:
As shown in FIG. 18B, a template management unit 184 is provided. The template management unit 184 selects the slot file 15 in the HA scenario template 13 specified by the user, the selection unit 184a, the copy unit 184b that generates a copy of the selected slot file 15 as the slot file 17, and deletes the copy. It has a deletion unit 184c. This template management unit 1
The slot file 17 after being copied by the copy unit 184 b in the file 84 is a target of the setting process for the variable items by the template setting unit 112. This slot file 1
7 can be generated by performing the selection process of the selection unit 184a and the copy process of the copy unit 184b a plurality of times in accordance with the user's specification.

The template setting section 112 selects and reads 185 the slot file 17 according to the user's specification.
(That is, a slot file 17 specified by the user is selected from a plurality of copies, and the selected slot file 1 is selected.
7 is read as a variable item setting target), and then a parameter setting 186 for each variable item in the slot file 17 is performed. And template setting unit 1
12 performs a save process 187 for overwriting and saving the contents of the slot file (17) already set to the variable items or in the process of being set in the original slot file 17 according to the user's designation. As a result, the variable items in the slot file 17 always have the latest setting contents, which facilitates version management. Next, when the design work is performed, the setting work can be continued by instructing the HA system design support unit 11 to read the overwritten saved slot file 17. In this case, reloading / saving 188 of the slot file 17 is performed. When performing the variable item setting for a new HA system, the template management unit 184 is started, the slot file 15 of the target HA scenario template 13 is selected, and the copy is made to the new slot file 17. Should be generated as

In the present embodiment, a frame file name 150 indicating the file name of the frame file 14 is recorded in a predetermined area of the slot file 15 forming the HA scenario template 13 in combination with the frame file 14. Have been. As shown in FIG. 19, the frame file name 150 corresponds to the slot file 15 in which the frame file name 150 is recorded.
Also in the case where the data is copied in the copy processing 190 of the HA system design support unit 11 and stored as a new slot file 17 (in the case of FIG. 18B), the template setting unit 1
When the slot file 12 reads the slot file 15 and performs a setting process for a variable item and saves it as a new slot file 17 (in the case of FIG. 18A), the slot file 17 is also read and changed to a variable item. When the setting process is performed and the original slot file 17 is overwritten and saved (in the case of FIG. 18B), the original slot file 17 is retained without being rewritten.

For this reason, the HA scenario generation unit 113 reads the frame file 14 in the corresponding HA scenario template 13 according to the frame file name 150 stored in the stored slot file 17 and generates the HA scenario 18. can do.

As described above, the file name (frame file name 150) of the corresponding frame file 14 is recorded as a fixed item of the slot file 15, and when copying the slot file 15 and setting a variable item,
By holding these fixed items, template information necessary for scenario generation can be obtained without having to always have the frame file 14 in combination with the slot file, that is, without having the frame file 14 duplicated. .

Next, a description will be given, with reference to FIG. 20, of checking an input value when setting a parameter input to a variable item for the slot file 17.

In this embodiment, the slot file 1
5, each variable item 120 has a value type 1 to be set.
21, a value range 122, and an implicit value 123 are added (see FIG. 12). Therefore, the type 121, the range 122, and the implicit value 123 maintain the state added to the variable item 120 in the slot file 17 as shown in FIG.

Therefore, the template setting unit 112
5 to 17, when performing parameter input setting to the variable item 120 according to the user operation through the GUI screen, each time one character input setting to one variable item 120 is performed (step 201), the variable item 120 is set to the variable item 120. In accordance with the type 121 attached, the type of the input character is checked (step 202). In this step 202, if the type 121 indicates, for example, an integer type, an input error other than a number is regarded as an input error, and if the type 121 indicates an IP address type, a process such as an input error other than a number and a period "." Done.

The template setting section 112 sets the variable item 1
Each time the input of the set value without the error of the character type for the character set 20 is completed, the type of the input set value is checked by the type 12
1 (step 203). This step 20
In No. 3, if the type 121 indicates, for example, an IP address type, an input error is made if the address format is not correct (even if the individual character type is correct).

The template setting section 112 executes step 2
If it is determined that there is no error in the type check of 03, range 1
According to 22, the range of the input set value is checked (step 204). In this step 204, for example, if it is an integer type, it is an input error if it is not between the minimum value and the maximum value indicated by the range 122, and if it is a character string type, it is an input error between the minimum and maximum character string lengths shown by the range 122 Otherwise, an input error is assumed.

The input set value to the variable item 120 is
The type and range check can be performed immediately after the input as in the present embodiment, or can be performed collectively for each GUI screen, for example.

For example, when the user gives a comprehensive check instruction after completing the input setting for all the variable items 120, the template setting section 112 performs the setting from the slot file 17 (even though there is no implicit value 123). The variable items 120 that have not been set, that is, all the unset items are searched (step 205), and the information on the existence and location of each of the searched unset items is notified to the user (step 20).
6). Further, even when an input error is detected in each of the checks 202 to 204, the template setting unit 112 notifies the user to that effect.

In the present embodiment, the HA scenario generation unit 113 has the function of checking the above-mentioned unset items. However, when generating the HA scenario 18 from the slot file 17 and the frame file 14 indicated by the frame file name 150 in the slot file 17, the HA scenario generation unit 113 automatically checks an unset item ( (Step 207), and the result is notified to the user (Step 208). The HA scenario generation unit 113
If no unset item is detected, HA scenario 1
8 is performed.

Here, details of the HA scenario generation operation by HA scenario generation section 113 will be described with reference to FIG.

The HA scenario generation unit 113 transmits the frame file 14 specified by the frame file name 150 held in the slot file 17 in which the values of the respective variable items are correctly set by the template setting unit 112.
Is read, and a variable item is searched from the description of the logical operation in the file 14 (step 211).

In this embodiment, the slot file 1
Each variable item in 5 is given a unique identification name. Therefore, each variable item in the slot file 17 is also given a unique identification name. The same identifier is also assigned to the variable item in the description of the logical operation of the frame file 14 corresponding to the variable item in the slot files 15 and 17.

Then, the HA scenario generation unit 113 searches the slot file 17 using the identifier attached to the variable item retrieved from the frame file 14 and acquires the set value of the variable item having the same identifier (step 21).

By describing the HA system operation management information 154 necessary for performing operation status monitoring / display (state display) and change operation together with the system design information 152, information such as an apparatus name and an IP address can be changed by a user. Since the information can be obtained from the HA system design information 152 in the same file (set to the item), these information
It is no longer necessary to define and hold the same in the A system operation management information 154. Further, since it is not necessary for the operation manager included in the HA scenario 18 (32) to analyze unnecessary information (information derived from the frame file 14), necessary minimum information can be obtained efficiently.

As described above, the HA system design information 152 has a type 121, a range 122, and an implicit value 123 for each variable item 120 (see FIG. 12). That is, the HA system design information 152 corresponds to FIG.
