DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic operation method of an information storage device for managing updating / retrieval of information in a storage system such as a database and a file, and an automatic operation system using the method.

[0002]

2. Description of the Related Art A general full-text search type database requires that registered data be in a unique format in order to perform a full-text search at high speed. As described above, an information storage system (such as a database or a file system that holds registered information, requests a specific format for each type of input data,
Or, when registering data in a system having means for receiving updates, the user must check the location (database name or the like) where the data to be input is registered and its format in advance. In such a case, data registration is usually performed by a system administrator who is familiar with the registration work, rather than a general user.

[0005] In an information storage system, various locks are generally used to ensure the consistency of information to be held. For this reason, in an information storage system that allows search and update to be performed in parallel by a plurality of transactions, in order to ensure data consistency, the processing target is updated during search processing by another transaction. I can't. Therefore,
The processing of the transaction that has requested the data update is delayed until the search processing by another transaction ends. Note that a transaction is one primitive (cannot be further decomposed) operation (operation such as writing or reading data) at the application program level, and usually means an operation on a database.
Here, it is assumed that the operation on other storage means such as a file is included.

[0004] In the information storage system, it is very important to ensure the reliability of the information held.
However, some database management systems (DBMS) such as the above-mentioned general full-text search type database and file systems do not provide a failure recovery function for preserving data retained at the time of failure. . Even if the DBMS has a failure recovery function, the update record must be written to a large-capacity storage device (such as a magnetic tape storage device) for each update process. Since input / output (I / O) to the mass storage device takes time, it causes a delay in processing.

[0005]

SUMMARY OF THE INVENTION Therefore, the present invention provides an information storage system which does not require a system administrator for registration work, and allows each user to independently register information in an information storage system. Automatic operation of the system,

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS In a first mode according to the first configuration of the present invention, an automatic operation system (server) responds to a request from an input system (client) to format information of registration data and notification destination information. To respond. The input system creates registration data in a format according to the returned format information, and notifies the automatic operation system together with the returned notification destination information. The Automated Operation System receiving this, based on the notified destination information,
A predetermined information storage system (server) is notified of the registration data, and the data is registered. This allows each user of the input system to independently create data in a predetermined format and register information in the information storage system. Therefore, according to the first aspect of the present invention, a system administrator for the registration work becomes unnecessary.

In the first embodiment, the notification destination information includes information indicating the information storage system of the notification destination (for example, D
BMS address, transmission location path name, database name, etc.) and storage location information (eg, physical address or logical address of the data,
Alternatively, it is desirable that the information storage system include information indicating these, such as information used as position information of data). In this case, the automatic operation system notifies the information storage system of the storage location information included in the notified notification destination information in addition to the notified registration data. With this configuration, the information storage system that has received the notification stores the registration data at a position corresponding to the notified storage position information, and thus can register data at a predetermined position.

[0015] In a second mode according to the second configuration of the present invention, the automatic operation system (server) stores the update data notified from the input system (client) in a temporary storage area, and stores the update data in a predetermined update condition. Is satisfied, the update data is notified to a predetermined information storage system (server). Accordingly, data update processing can be performed without making the user aware of the lock wait of the update processing, and concurrency as seen from the user of the update work can be ensured. This second aspect may further include the first configuration of the present invention.

In the second mode, the update condition is
It can be assumed that a predetermined time has elapsed since the last update or search to the information storage system. Further, it may be that a predetermined time has elapsed since the update data was finally notified to the information storage system, and since the update data was finally notified to the information storage system,
A predetermined number of searches may have been performed. in this way,
It is desirable to set the update condition according to the properties of the network system or information storage system to be operated or the information registered in the information storage system.

In a third mode according to the third configuration of the present invention, the information storage system provided in the server is duplicated into a reference system and an update system. The automatic operation system (server) of this aspect stores the same update data in an update data storage area (a storage area for temporarily storing the update data) when notifying the update data to the update DBMS. Further, when a predetermined switching condition is satisfied, the automatic operation system switches between the reference system and the update system, and notifies the new update system of the update data held in the update data storage area. Thereby, data reliability can be ensured without using the failure recovery function of the information storage system. This is because, even if a failure occurs in one of the duplicated information storage systems, information can be easily restored by copying the other system. When the information of the information storage system is restored in this way, if the information held by the restored information storage system is updated using the update data held in the update data storage area, the data can be restored when a failure occurs. State can be returned.

The notification of the update data to the update DBMS and the storage of the update data in the update data storage area may be performed simultaneously or continuously, but may be performed at different timings as in the second mode. Good. That is, when receiving the notification of the update data, the automatic operation system first stores the update data in the update data storage area, and if a predetermined update condition is satisfied, updates the update data held in the update data storage area. May be notified to the information storage system. By doing so, it is possible to ensure the simultaneous execution of the update work, as in the second aspect. In this case, as in the case of the above-described second aspect, the update condition is appropriately set according to the properties of the operating network system, information storage system, or information registered in the information storage system. It is desirable to do.

Similarly, the switching condition can be appropriately set. For example, a predetermined time has passed since the last switching of the information storage system for the switching target, and the search or update is performed in any of the information storage systems constituting the pair to be switched. It may be determined that it is not being executed, or that the search or update is not being executed in any of the information storage systems to be switched, and that the update data is stored in the update data storage area. Alternatively, the switching condition is that the search or update is not being executed in any information storage system to be switched, the update data is held in the update data storage area, and the information storage After the system is switched, the reference process performed on the reference information storage system to be switched may have reached a predetermined number of times.

The value (initial value 0) held in each elapsed time storage area 422 is increased according to the elapsed time. The means for increasing the value held in the area 422 may be a clock circuit.
Alternatively, a means using software using a clock built in the information processing apparatus may be used.

Next, the automatic operation system 12 of this embodiment
The flow of processing of the communication control means 45 at 0 will be described with reference to FIG.

First, upon receiving data input (step 601), the communication control means 45 of the present embodiment determines that the input source is an input system (step 60).
2) It is checked whether the input is an inquiry for format information (step 603).

If the query is for format information,
The communication control unit 45 passes the notified data type to the format notification unit 46, and inquires the format information and the notification destination information held in the data type information storage area 51 of the data type table corresponding to the data type. Notify the original input system and execute the process at step 60.
It returns to 1 (step 604). This step 60
The format notifying unit 46 to which the data type has been passed in step 4 searches the data type table 43, reads out the data type information storage area 51 corresponding to the passed data type, and stores the contents of the area 51 in the communication control unit 45. Notify.

If the input is not an inquiry for format information in step 603, the communication control means 45 checks whether or not the input is a notification of registration data (step 605).

If the input is the notification of the registration data, the communication control means 45 stores the notified registration data and transmission destination data in the registration waiting information storage area 52 of the registration data storage area.
And the process returns to step 601 (step 6).

A registration command of the registration data waiting for registration is issued to 30, and the actual update (commit) process is performed. Step 703 may not be performed. In this case, the condition for issuing the registration command is that a predetermined time has elapsed since the last access except for registration was made to the information storage system to be registered.

(3) Information Storage System As shown in FIG. 1, the information storage system 130 of this embodiment includes a database management system 131 and a plurality of databases 132 managed by the database management system 131. Although the network system 100 of the present embodiment includes a plurality of information storage systems 130, the number may be one, and the number of databases 132 included in each information storage system 130 depends on the function of the database management system 131. As many as you allow. Note that any commonly known system can be used for the database management system 131. In the present embodiment, a system that stores information in a database is used as the information storage system 130. For example, a system that stores information in a file may be used.
A system for storing information by other means may be used.

When database management system 131 receives registration data in a predetermined format together with a registration instruction, database management system 131 registers the registration data in database 132. Also, in the case of instructions such as data search, deletion, and correction instructions, predetermined processing is performed in the same manner as in a normal database management system.

When the notification destination information includes a logical address in the database 132, the database management system 131 uses the notified storage location information to
A device having means for determining the storage position of registration data is used. By using such a database management system 131, the position of the database 132 indicated by the storage position information notified together with the registration data is
Registration data can be stored.

C. According to the present embodiment, the automatic operation system previously holds the format information and the notification destination information of the registration data, and the input system notified of this by the inquiry transmits the registration data of the notified format. To create the information, the user of each client can independently register information in the information storage system 130. Therefore, according to this embodiment, there is no need to prepare a system administrator for the registration work.

Further, according to the present embodiment, since the registration of data at the request of the client is performed in the registered data storage area of the automatic operation system without waiting for the lock, the client needs to wait for the lock. Absent. Therefore, according to the present embodiment, the concurrency as seen from the user of the registration work is ensured.

In this embodiment, of the update processing, only the registration processing is performed by the registration data notifying means 44. However, for all the update processing, the update data is temporarily stored in the registration data storage area 41. Therefore, the registration data notification means 44 may issue an update command. By doing so, the concurrency as seen from the user is ensured for all update processes.

In 204, if the automatic operation system 150 inquires about the format in the update process other than registration (the inquiry in step 33 described above), it notifies only the notification destination information to the inquiry source. Here, the type of data required for the update process requested by the database management system 131 of the information storage system 130 may also be notified.

If the input is not an inquiry for format information in step 1203, the communication control means 95 checks whether the input is an instruction for an update process (step 1205).

If the input is an instruction for an update process, the communication control means 95 replaces the notified update data and the destination information with each other.
It is stored in the registration waiting information storage area 52 of the update data storage area 47, and the process returns to step 1201 (step 1).
206).

If it is determined in step 1205 that the input is not an update instruction, the communication control means 95 determines that the input instruction includes a predetermined command (that starts a transaction) (step 12).
07), the identifier of the pair 90 of the destination information storage system 130 in the user counter 50 is stored in the pair identifier storage area 5
The value held in the lock area 503 of the row held in 01 is 0
Is stored in the lock area, and the value held in the number-of-users storage area 502 of the row is increased by one.
0 is stored in the lock area (step 1208). Finally, based on the identifier of the pair 90 included as the notification destination in the input data, the communication control unit 95 reads the address of the reference information storage system 130 included in the pair 90 from the system configuration table 48. Is detected, the input content is notified to the address, and the process is performed in step 12
01 (step 1209).

If the source of the input received in step 1201 is information storage system 130 (step 1202), communication control means 95 determines that the input content is
If it is an end notification for a predetermined command (for ending the transaction) (step 12
10) The identifier of the pair 90 of the destination information storage system 130 in the user counter 50 is stored in the pair identifier storage area 5.
The value held in the lock area 503 of the row held in 01 is 0
Is stored in the lock area, the value held in the number-of-users storage area 502 of the row is reduced by 1, and 0 is stored in the lock area (step 1211). (Excluding the end notification of the update processing) to the transmission destination designated by the information storage system 130 by the input, and returns the processing to step 1201 (step 12).
12). Similarly to the notification of the end of the registration processing of the first embodiment, the communication control system 95 of the present embodiment does not notify the input system 110 of the notification of the end of the update processing (registration, deletion, or modification) in step 1212. But,
For example, the notification may be made by notifying the input system 110 in the case of the notification of the normal end, but generating an interrupt to the input system 110 only in the case of the notification of the abnormal end (rollback or the like).

Next, the automatic operation system 15 of this embodiment
The processing flow of the switching means 49 at 0 will be described with reference to FIG.

The switching means 49 of this embodiment reads the data transmission address storage area 521 of all the registration waiting information storage areas 52 in which the data of the update data storage means 47 is registered, and 40
Of the row in which the same identifier as the pair identifier (pair A) held in the area 521 is stored in the pair identifier storage area 401, a predetermined elapsed time (10 in this embodiment) is stored. A search for a value larger than (minute) is searched (step 1301), and if not detected (step 1302), the process waits for one second and returns to step 1301 (step 1303).

At step 1301, when one row holding a value larger than the predetermined elapsed time in the elapsed time storage area 402 is detected, the switching means 49 sets the pair identifier storage area of the row (hereinafter referred to as row A). Based on the pair identifier held in 401, wait until the value held in the lock area 50 corresponding to the pair of the user counter 50 becomes 0, store 1 in the lock area 50, and correspond to the pair. The value held in the number-of-users storage area 502 is read. If the number of users is not 0 (step 1305), switching means 4
9 stores 0 in the lock area 50 corresponding to the pair (step 1306), and stores a value larger than the predetermined elapsed time in the elapsed time storage area 4 in the same manner as in step 1301.
02 is searched for another row (step 130).
7). If there is another row (step 13)
08), with the line as a processing target,
4 and if there is no other row (step 1308), 1
After waiting for two seconds, the process returns to step 1301 (step 1
303).

At step 1305, the number of users is 0
Then, the switching means 49 stores 0 in the elapsed time storage area 402 of the timer 40 corresponding to the pair A (step 13).
09), the address held in the reference storage area 481 and the address held in the update storage area 482 in the row corresponding to the pair A in the system configuration table 48 are exchanged (step 1310).

As described above, since the reference system and the update system have been switched, next, the switching means 49
The update command is created using the update data and the header held in each of the registration waiting information storage areas 52 holding the identifiers in the data transmission address storage area 521. The information is transmitted to the update information storage system 130 of the pair A via the communication control means 95 (step 1311).

Finally, the switching means 49 determines in step 131
1 deletes all the data in the registration waiting information storage area 52 used to create the update command (step 13).
12) Then, 0 is stored in the lock area 503 corresponding to the pair A (step 1313), and the process returns to step 1301 after waiting for one second (step 1303).

According to the above processing, the switching processing is performed on a pair of information storage systems 130 that have passed a predetermined time since the last switching processing was performed and have no transaction being accessed. An update command for update data waiting for update is issued to the system information storage system 130, and the actual update (commit) process is performed. Step 1301 and step 130
In step 7, instead of checking whether the predetermined time has elapsed, it may be checked whether the number of references and / or the number of update data has reached a predetermined value.
