Abstract

PURPOSE: To automatize the reraising of the output of a WS memory dump and subsequent WS and to resume AP from a state at the time when a WS error has occurred. CONSTITUTION: A diagnosis means 3 holds AP information of AP 1 during execution at that time in an AP information holding area 5, then stops AP1 when the occurrence of the WS error is detected by WS diagnosis, and outputs the WS memory dump to a WS memory dump file is a dump preservation storage medium 4. A restarting means 2 cuts/supplies the power of WS20 in terms of software after the output of the WS memory dump by the diagnosis means 3, reraises WS20 and resumes AP1 from the state at the time when the WS error has occurred, based on AP information preserved in the AP information preservation area 5 by the diagnosis means 3 when the WS error occurred, after WS20 is reraised.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a host computer (office processor, etc.) and WS (WorkStati).
on. Workstation (WS) error in the computer system connected to the workstation (error in WS running by AP (Application Program) application program on the host computer side, eg WS stall), WS memory dump is output and WS memory is output. The present invention relates to a WS memory dump output / WS restarting method in which a WS is restarted after a dump is output.

[0002]

2. Description of the Related Art Conventionally, this type of WS memory dump output
In the WS restart method, if a WS error occurs,
The WS terminates abnormally in the state when the WS error occurs, and the host computer determines that the power of the WS has been turned off based on the detection of status information indicating the occurrence of the WS error, and forces the running AP. It was ended (abnormally ended).

In order to re-execute the AP, the operator turns off / on the power of the WS hardware and
After S was restarted, the AP was re-executed based on the AP restart instruction from the operator. Here, the AP is forced to be re-executed from the beginning rather than being restarted from the state when the WS error occurred.

Further, when collecting a WS memory dump, an FD (Floppy Disk, floppy disk) is operated by an operator before restarting the WS.
It was necessary to output the WS memory dump to the above. Since the operation of the operator intervenes in the collection of such a WS memory dump, there is a high possibility that a collection error (error) will occur.

FIG. 3 is a flow chart showing the outline of the processing of the above-mentioned conventional WS memory dump output / WS restarting system.

[0006]

In the above-described conventional WS memory dump output / WS restarting system, operator intervention is required to re-execute the AP that has abnormally terminated due to a WS error. There is a problem in that it takes time to perform a predetermined measure and man-hours for re-execution of AP. Moreover, since the information indicating the state of the AP when the WS error occurs (the state of the data handled by the AP when the WS error occurs and the execution point when the WS error occurs) is not saved when the AP abnormally ends, Upon re-execution, it was necessary to start execution of the AP from the beginning.

Further, since operator intervention is required to output the WS memory dump, it is difficult to reliably and accurately collect the WS memory dump when a WS error occurs (without a collection error), and the WS memory dump is collected. If not possible, there is a problem that the operating state of the WS at the time of occurrence of the WS error cannot be confirmed and the cause analysis of the WS error becomes difficult.

In view of the above points, an object of the present invention is to automate the output of a WS memory dump and the subsequent restart of the WS, and to deal with the WS error as soon as possible.
So that it can be restarted from the state when the WS error occurred.
To provide a WS memory dump output / WS restarting method capable of reliably and accurately collecting a memory dump when an S error occurs, and reducing the man-hours of an operator for dealing with a WS error. is there.

As a conventional technique relating to the automation of the output of the WS memory dump, see Japanese Patent Laid-Open No. 196740/1987.
Japanese Unexamined Patent Publication (fault data communication device) "is disclosed. However, the conventional technique according to this publication relates only to the automation of the output of the WS memory dump, and the WS after the automatic output of the WS memory dump as in the present invention.
Automatic restart (including restart from the state when the AP WS error occurs) is not mentioned at all. Where W
The essence of the present invention is that the automatic collection (output) of the S memory dump and the automatic restart of the WS are performed as a series of processes (for example, if only the restart of the WS is automated, the operator The WS memory dump can no longer be collected due to, and the demerits are greater than the merits.),
The purpose and configuration of the prior art relating to the publication, which mentions only one of them, and the present invention are different.

[0010]

According to the WS memory dump output / WS restart method of the present invention, a dump storage storage medium in a host computer for storing a WS memory dump file and AP information when a WS error occurs are stored. The AP information storage area in the memory of the host computer and when the WS diagnosis detects the occurrence of a WS error, the AP information at that time of the AP being executed is stored in the AP information storage area and then the AP is stopped. Then, the diagnostic means for outputting the WS memory dump to the WS memory dump file in the dump storage storage medium, and after the WS memory dump is output by this diagnostic means, the power of the WS is turned off / on by software. When the WS error is generated after the WS is restarted, the A
And a restart means for restarting the AP from the state when the WS error occurred based on the AP information stored in the P information storage area.

[0011]

In the WS memory dump output / WS restart system of the present invention, the dump storage storage medium in the host computer stores the WS memory dump file, and the AP information storage area in the memory in the host computer causes a WS error. The AP information at the time is saved, and the diagnosis means W by the WS diagnosis.
When the occurrence of the S error is detected, the AP information at that time of the AP being executed is stored in the AP information storage area, the AP is stopped, and the WS memory dump is output to the WS memory dump file in the dump storage storage medium. After the restart means outputs the WS memory dump by the diagnostic means, the WS power is turned off / on by software to restart the WS, and after the WS restart, when the WS error occurs, the diagnostic means causes the AP information storage area. The AP is restarted from the state when the WS error occurred on the basis of the AP information stored in.
