Abstract

PURPOSE:To commonly use a display device as a system console and work station, by making the attribute of the display device changeable to a mode, in which a CPU is changed in accordance with a changing request. CONSTITUTION:When, for example, a device operating as a work station is to be used as the console of a service processor SVP which is able to make system IPL operation, for eample, XO3 is designated as a mode changing request to the SVP console. The field is sent out correspondingly to the device when the hardware attribute to a display device under a pheripheral type display controlling device SWP5 is changed. When a system request key is depressed by an operator thereafter, the SWP5 interrupts the cession of a corresponding display device and makes the display device operate as a console.

Description

Detailed Description of the Invention [Technical Field of the Invention] The present invention relates to a terminal control device (SWP;
%rkstationProcessor) 1 A shared control method for system consoles and workstations that enables asynchronous switching between the system console (SVP console) and workstations using the 5YSREQ key of the peripheral display device under it. It's busy work.

[Conventional technology and problems]

Conventionally, when configuring a system, it has not been possible to asynchronously share a peripheral display device as a system console and workstation. Generally, a peripheral display device that inputs operation commands is called a console, and in addition to this console function, it also has system
PL (In'ifialPrcgran lIoadi
ng) One so-called system console (SVP console), which performs operations and also has 5 functions, is always provided in the system. Conventionally, these consoles cannot be used as workstations, so for example, if a system that was previously operated only by a console uses a workstation, it is necessary to install an additional display device as a workstation. . Therefore, the cost of the system naturally increases, and the operator also has to operate a plurality of peripheral display devices, resulting in poor operability.

[Purpose of the invention]

The present invention is based on the above considerations, and provides that a peripheral display device can be shared as a system console and a workstation, and that switching between the system console and work stage can be performed during the session. Its purpose is to provide a shared control method between the system console and workstation that can be controlled asynchronously.

[Structure of the invention]

To this end, the shared control system between the system console and the workstation of the present invention includes a main storage device, a central processing unit, a terminal control device channel-coupled to the central processing unit, and a service processor under the terminal control device. This is a shared control method between a system console and a workstation, which switches the display device under the terminal control device between the system console and the workstation, and is equipped with a display device that can operate as a workstation. Structured field sent to the display device when changing attributes for the display device under the control device, display device system-request Notification means for notifying when the 0 key is pressed, can operate as a service processor A mode switching means is provided for the display device, and the terminal control device switches the display device under the terminal control device after the central processing unit issues a system request key validation instruction using the structured field. When the system request key is pressed, the notification means notifies the central processing unit, and a mode switching request between the system tatami console φ moderated workstation mode and the structured workstation mode of the display device is notified. The present invention is characterized in that, when executed by the central processing unit in accordance with the field, the process of changing the attribute of the display device to the mode according to the switching request is performed as shown in line 5.

These functions are valid only for peripheral display devices connected to the SWP5.

The S field is a data stream that contains character data, other types of data, and regulatory information, and that performs a unique function on its own. FIG. 2 shows the data format of the S field for 5WCF. In Figure 2, Lengt

When using a device that is operating as a P console as a workstation, specify, for example, SV the equipment that is
When used as a P console, specify, for example, X03 as a mode switching request to the SVP console. This S field is used when changing the hardware attributes for a display device under 5WP5.
It is sent as an S field depending on the device.

When the 5YSREQ key is pressed by the terminal operator after the 5YSREQ key validation instruction is given by the S field, the asynchronous status that is notified to the software and its interface are explained in FIG. 3. Also, for example,
Figure 4 explains an interface using an asynchronous status in which on +Busy+TJnit Check) is the device status and XvFFma (mode switching request) is the sense status.
Ma86ma (Attention +TJnit Che
FIG. 5 illustrates an interface based on synchronous status and asynchronous status, with ek +Device END) as the device status and XvFFma (mode switching request) as the sense status.

The 5YSREQ key is indispensable to realize the asynchronous switching function of SWCF, and is provided on the keyboard of the display device. When pressed by the operator, the current process is interrupted and other processes are started. It allows you to do it.

Its function is that when operating as a workstation, it can suspend sessions and operate as a console. Furthermore, when operating as a console, the following processing is performed depending on the state of the application program connected to the terminal. First, if the session has been interrupted (by pressing the SYSREQ key), it will resume operation from that point. The second is to interrupt the session (5YSREQ key
However, if the session is terminated when the session is switched to the console, the restart process will not be performed. Therefore, depending on the connection method of the terminal, the 5YSREQ key is used when performing asynchronous switching on a terminal under swP in the case of a peripheral type, and is used for LOGON/Switching on a line type AC terminal.
Used when performing LOGOFF operation.

When using the display device as an SVP console or workstation, the PF
Key (Program Function Key) assignment differs depending on hardware attributes (modes).

FIG. 6 shows one example.

Mode switching on the SVP Consolet Workstation hardware attribute may be performed by pressing the 5YSREQ key or by requesting a mode change using the S field. 5YSRE by S field
When the terminal operator presses the 5YSREQ key after the Q key validation instruction is issued, the terminal operates as an SVP in terms of hardware regardless of the mode at that point. Further, when a mode switching request is issued by the S field, the mode is switched to the mode specified there. If the Feature Type of the S field is, for example,
In the case of a host, the mode switches to the SVP console mode.

For example, when switching the hardware attribute mode, s
r on the vp console, "R mouth" on the RDPC8LJ workstation, r RM on the manual frame
Displays mode identification, such as ANOPJ. SVP
FIG. 7 shows a switching diagram of hardware attributes in the console. In Figure 7, 5Y indicated by *1
The SREQ key is treated as N0P (No0operation), and the 5YSREQ key indicated by *2 causes an asynchronous interrupt.

Next, the processing of light console messages will be explained. Light console commands do not affect the mode of hardware attributes; erasure/display of light console messages is controlled by the 5YSREQ key. The processing when a write command is issued before resetting the light console message is as follows: (1) Save the light console message on line 24 in swp.

■ Display write data.

■ Save the information on the 24th line of the write data in swp.

■ Display the light console message on the 24th line.

Therefore, if a write command is issued before the write/console/messenger is reset, the processing speed will drop because the above sequence is processed. FIG. 8 shows an overview of the processing of light console messages.

In the present invention, when operating as a workstation, it is possible to switch to the console without terminating the session (LOGOFF command), and to switch to the console again after the operation as the console is finished. When switching to a station, the previous processing can be continued.

In asynchronous switching, when the terminal operator presses the 5YSREQ key, the switching processing is performed through a switching processing routine based on information notified from the hardware. This asynchronous switching function is supported only for display devices under SWP. In addition, for display devices under SWP, asynchronous switching and RCF
(It is also possible to use the synchronization switching function using Tkmote Con5ole Facilit) in combination.

RCF is VTAM (Virtual Telecomm)
unicationAecessMethod), and after completing TAM initialization, R
It can be used as a console by starting CF (starting with the "BEGIN RCF" command) and inputting the "LOGONCONS" command from the terminal. Further, when it is desired to use the device used as a console in combination with an application program (AIF/AIM, etc.) under the workstation, the console operation is stopped by the "LOGOFF" command, and then the 'LOGON' command is used.

Note that after VTAM is stopped, it cannot be used as a console. 5WCF operates as a console since IPI, and can guarantee the same operation as RCF without depending on VTAM start/stop processing. 5v
Figure 9 shows the aspect of asynchronous switching between the Pj console and workstation, and Figure 10 shows the aspect of the display screen switching process during asynchronous switching.
It is a diagram. In FIG. 10, 0VIS is the name of one system, and the processing is performed in five rows using the menu screen.

〔Effect of the invention〕

As is clear from the above description, according to the present invention, C, Sv
There is no need to prepare a separate display device for the P console, and switching between the workstation and the console can be done without disconnecting the session. This reduces the system price and greatly improves operator operability.
