8 and an execution unit 19 as control means for executing the processing operation based on the processing content selected by the control command conversion processing unit 18.

In this embodiment, two types of OS1
As one, UN of SVR4 system developed by Sun Microsystems
Solaris (Solaris) 11A, which is an IX integrated environment, and Lynx (Lynx) 1, which browses text-based data
1B is installed, and the interfaces of the Solaris 11A are made compatible with the interfaces of the Solaris 11A.

A command character string is transmitted and received between the OS 11 and the OS control unit package 20 through the communication control unit 21, and a received character string message from the OS 11 to the OS control unit package 20 is, for example, an open message. There is an open boot operation character string for notifying that a boot operation is being performed. When the OS 11 is Solaris 11A, a character string of “ok \ r” is displayed.
In the case of B, the character string “PPC6-Bug>” is used.

The OS identification unit 22 of the OS control unit package 20 receives such a received character string message at the time of booting the OS, so that the currently operating O
S11 can be identified.

Now, here, each OS 11 (Solaris 11
A, Lynx 11B) will be described focusing on the start / stop / restart command. FIG. 2 is an explanatory diagram showing the contents of the control command conversion table 23, and FIG. 3 is an explanatory diagram showing the contents of the control command conversion table 17.

For example, in the normal specification of Solaris 11A, the start command is "rb", the processing content is "start OS", the stop command is "shutdown", the processing content is "stop at prompt" and Change the start command to "rebo
ot ", and the processing content is" automatically restart by OS ". The prompt means a command input waiting state.

On the other hand, in the normal specification of the Lynx 11B, the start command is “rb”, the processing content is “OS start”, and the stop command is “reboot-h” in the auto boot OFF environment. The content is "stopped in an infinite loop and stopped", the restart command is "reboot", and the processing content is "dropped to the prompt and cannot be restarted".

That is, in the control command table 23 of the OS control unit package 20, as shown in FIG. 2, in the case of a start request, the start commands of "rb" (Solaris) and "rb" (Links) are stopped. "Shutdow
In the case of a stop command of “n” (Solaris) and “reboot-h” (Links), and in the case of a restart request, a restart command of “reboot” (Solaris) and “reboot” (Links) are stored in advance.

Further, as shown in FIG. 3, the control command conversion table 17 of the OS 11 stores "rb" (Solaris)
"OS startup" as processing contents corresponding to the start command of "Shutdown" (Solaris) "Stop at the prompt", "re
“Restart automatically by OS” is stored as the processing content corresponding to the restart command of “boot” (Solaris).

The control command conversion table 17 is
According to the normal specifications, “OS boot”, “reboot-
h "(Links) stop command corresponds to the processing content" falls into an infinite loop and stops "." reboot "(Links) restart command corresponds to the processing contents" falls to the prompt and cannot be restarted ". As shown in FIG. 3, here, as shown in FIG. 3, processing contents corresponding to the “rb” (links) start command include “OS start” and “reboot-h” (links) stop command. The corresponding processing contents are "stop at the prompt and stop", "re
It is assumed that "the register is turned on, the display is stopped at the prompt, and the operation is stopped" is stored in advance as the processing content corresponding to the restart command of "boot" (links).

That is, the processing contents corresponding to the “reboot-h” (Links) stop command and the processing contents corresponding to the “reboot” (Links) restart command are stored as contents different from the normal specification. .

When the control command conversion processing section 18 of the OS 11 receives the "reboot-h" which is the stop command of the link 11B, the control command conversion processing section 18 determines that the processing content corresponding to this stop command "stop at the prompt" and "stop". This will be selected from the conversion table 17.

When the control command conversion processing section 18 of the OS 11 receives the “reboot” which is the reboot command of the link 11B, the processing content “register is turned on corresponding to the reboot command, and the prompt "Stop" is selected from the control command conversion table 17.

Next, the operation of the OS control device 1 shown in this embodiment will be described. FIG. 4 is a flowchart showing a processing operation related to the OS control device 1 when a stop request is issued during the operation of the Lynx 11B.

In the OS identification unit 22 of the OS control unit package 20, when the OS 11 is started, the OS
It is assumed that the currently operating OS 11 has been identified as the Lynx 11B according to the character string received from the OS 11.

In FIG. 4, when the shutdown button of the command operation unit 50 for requesting a stop command from the user is pressed (step S1), the OS unit side communication control unit 1
3 transmits a stop request notification corresponding to the press of the shutdown button to the OS control unit package 20 (step S2).

When the control command selection unit 24 of the OS control unit package 20 receives the stop request notification through the communication control unit 21 (step S3), the control command “reboot”, which is a control command of the link 11B corresponding to the stop request notification, is received.
-h "is selected from the control command table 23 (step S4), and the" reboot-h "stop command is transmitted to the OS 11 through the communication control unit 21 and the OS unit-side communication control unit 13 (step S4). S5).

Control command conversion processing unit 18 on OS 11
Receives the stop command of "reboot-h" (step S6), selects the processing content "stop at the prompt and stops" corresponding to the stop command of "reboot-h" (Solaris) from the control command conversion table 17 (Step S
7).

The execution unit 19 on the OS 11 executes a control operation based on the processing content selected by the control command conversion processing unit 18, and the OS 11 (Links 11B) drops to a prompt and stops (step S8). ), This processing operation ends.

According to the processing shown in FIG. 4, even if the stop commands ("shutdown", "reboot-h") are different between the Solaris 11A and the links 11B as in the case of the stop request notification, the processing contents are not changed. "Stop at the prompt"
Therefore, the processing contents corresponding to the same request notification can be shared among a plurality of OSs 11.

FIG. 5 is a flowchart showing a processing operation related to the OS control device 1 when a restart request is issued during the operation of the links 11B.

In FIG. 5, it is determined whether or not the IPL button of the command operation unit 50 for requesting a restart command from the user has been pressed (step S11).

If the IPL button has been pressed, O
The S unit side communication control unit 13 transmits a restart request notice corresponding to the pressing of the IPL button to the OS control unit package 20 (step S12).

When the control command selecting unit 24 of the OS control unit package 20 receives the restart request notification through the communication control unit 21 (step S13), the control command selecting unit 24 transmits the control command of the links 11B corresponding to the restart request notification. A restart command of a certain “reboot” is selected from the control command table 23 (step S14).

The control command selector 24 selects the selected “re
A restart command “boot” is transmitted to the OS 11 through the communication control unit 21 and the OS unit side communication control unit 13 (step S15).

7).

The execution unit 19 includes the control command conversion processing unit 1
Based on the processing content selected in step 7, the IPL register 14 is turned ON, and the processing operation is performed so that the prompt falls and the OS 11 (links 11B) stops (step S18). Further, it is determined whether or not the currently operating OS 11 (Links 11B) has dropped to the prompt (step S19).

If the currently operating OS 11 has dropped to the prompt, the communication control unit 21 of the OS control unit package 20 reads the contents of the IPL register through the register reading unit 25, and the IPL register 14 is ON. Check.

When it is confirmed that the IPL register 14 is ON, the communication control section 21 transmits a start request notification for starting the OS to the control command selecting section 24.

The control command selection unit 24 selects a start command “rb”, which is a control command of the Lynx 11B, corresponding to the start request notification for starting the OS 11, from the control command table 24 (step S20).

Further, the control command selecting section 24 transmits the selected start command “rb” to the control command conversion processing section 18 of the OS 11 through the communication control section 21 and the OS section side communication control section 13 (Step S21).

When receiving the start command “rb” (step S22), the control command conversion processing unit 18 selects the processing content “OS start” corresponding to the start command “rb” from the control command conversion table 17 (step S22). S2
3). The execution unit 19 executes the OS 11 (Links 1) based on the processing content selected by the control command conversion processing unit 17.
1B) is executed (step S2).
4), the processing operation ends.

If the IPL button has not been pressed in step S 21, the IP
It is determined whether or not the L register 14 is ON. When the IPL register 14 is in the ON state, it indicates that the application program 12 has abnormally terminated.

If the IPL register 14 is in the ON state, the application program 12 ends abnormally and the OS 11 has dropped to the prompt. Thereafter, the application program 12 that has abnormally ended can be recovered by starting the OS by the processing operations of steps S20 to S24.

According to this embodiment, the OS 11 currently in operation is specified by the OS identification unit 22 and the command operation unit 50 is specified.
The control command selection unit 24 selects a control command related to the currently operating OS 11 corresponding to the request notification from the control command, and the control command conversion processing unit 18 selects processing content corresponding to the control command. Since the control operation is executed based on the content, even if a plurality of OSs 11 are installed, the currently operating OS 11 is specified, and the processing operation based on the control command and the processing content corresponding to the request notification is performed. Can be performed smoothly.

According to the present embodiment, when the application program 12 is abnormally terminated while operating on the OS 11, the register writing unit 15 of the application program 12 turns on the IPL register 14. By doing so, the OS control unit package 20
