Description

DETAILED DESCRIPTION OF THE INVENTION [Outline] In a data processing system having an automatic operation mechanism, when the initial setting process of the system is completed,
Record the IPL completion date, and after the automatic IPL of the system, recognize the date of the current day, and this date,
By providing a means to compare the previous automatic IPL completion date, only the initial setting (system setup) processing will be performed if the current day's date matches the previous date, and initialization will be performed if they do not match. The initial setting process is performed after the process (clearing the work disk, etc.) is performed.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an initial setting (system setup) processing method in a data processing system having an automatic driving mechanism.

With the recent widespread use of computer systems, it has become necessary to save labor when operating the computer systems, and the computer systems have been equipped with an automatic operation mechanism.

When automatic operation of the computer system starts, at the start of normal operation, it is necessary to clear (all) the information of the previous day and then set up (start up) the system. In some cases, while maintaining the system resources at that time,
You need to set up the system.

It is necessary to determine the difference in the setup process of such a system and effectively perform the initial setting.

[Problems to be solved by conventional technology and invention]

FIG. 2 is a diagram schematically showing a conventional initialization processing method.

First, when the automatic power-on timer provided in the automatic power control device (APC) 3 recognizes that the power-on time has come, the automatic operation mechanism (of the data processing system) via the service processor (SVP) 2 AOF) 1 is started and the following automatic driving operation is performed.

Step 10: Automatically power on the main unit.

Step 11: Subsequently, automatic initial program loading (IPL) is performed, and when the automatic IPL is completed, the process proceeds to the next step.

Step 12: Perform the initial setting (system startup) processing automatically or manually.

In the case of automatic operation, for example, initialization (clear) of the work area of the file memory (FM) 4, cancellation of an output waiting job, resetting of the job number, etc. are performed, and then the system is brought into operation. Starts up various necessary subsystems (initial setting processing).

In the case of manual operation, after performing the above initialization processing, various subsystems necessary for the operation of the system are started (initialization processing), or the initialization processing is not performed and only the initialization processing is performed. Whether or not to perform is instructed by the intervention of the operator.

Step 13: Enter system operation. If a failure occurs during operation and the system goes down, the process returns to step 11, re-automatic IPL is performed, and the next initialization process starts.

Step 14: Based on the end time instruction from the automatic power supply controller (APC) 3, the automatic system end processing is performed.

Step 15: According to the timer instruction of the automatic power supply controller (APC) 3, the automatic power supply to the main unit is cut off.

Therefore, when the initialization process is automated, there is a problem that the system resources immediately before the system goes down are cleared by the initialization including the initialization process.

When it is necessary to restart the system operation using the system resources just before the system goes down, for example, the initialization process without initialization process must be instructed by the intervention of the operator. There was a problem that it would disappear.

In view of the above-mentioned conventional drawbacks, an object of the present invention is to provide an initial setting processing method in automatic driving that automatically determines and performs correct initial setting processing corresponding to the state of the system when performing automatic driving. It is a thing.

[Means for solving problems]

FIG. 1 is a flow chart of processing showing a configuration of an initial setting method during automatic operation of the present invention.

According to the present invention, in a data processing system having an automatic operation mechanism (AOF) 1, a means 4 for storing the last automatic initial program loading (IPL) completion date, a means 1a for setting the date of the current day, Means 16 for comparing the automatic initial program loading (IPL) completion date of the above and the current day's date, and when the current day's date matches the previous automatic initial program loading (IPL) completion date Executes only the system initialization process 120 and checks the current day's date and the previous automatic initial program loading (IP
L) Initialization processing 1 if the completion date does not match
After performing step 21, the initial setting process 122 is configured to be performed.

[Action]

That is, according to the present invention, in a data processing system having an automatic operation mechanism, when the initial setting process of the system is completed, the automatic IPL completion date of the system is recorded,
After automatic IPL of the system, by recognizing the date of the current day and providing a means for comparing this date with the previous automatic IPL completion date, the date of the current day,
If the previous date matches, only the initial setting (system setup) processing is performed, and if they do not match, the initialization processing (clearing the work disk, etc.) is performed, and then the initial setting processing is performed. Therefore, there is an effect that the initial setting process at the time of automatic operation can be correctly performed according to the aspect of the system, and the system resource can be held at the time of system down.

〔Example〕

 Embodiments of the present invention will be described in detail below with reference to the drawings.

FIG. 1 described above is a flow chart of the processing showing the configuration of the initial setting method during automatic operation of the present invention.
~ 122 are the means necessary to carry out the present invention.
The same reference numerals indicate the same objects throughout the drawings.

Hereinafter, referring to FIG. 1, the initialization processing method during automatic operation of the present invention will be described.

Even if the present invention is carried out, the starting operation from the automatic power supply controller (APC) 3 to the automatic driving mechanism (AOF) 1 is not particularly different from the conventional one, and therefore the description thereof is omitted. Here, after the automatic IPL operation in step 11. The operation associated with the present invention will be mainly described.

Step 11: Perform automatic initial program loading (IPL), and when the automatic IPL is completed, move to the next step.

Step 16: In the data processing system to which the present invention is applied, when the automatic IPL is completed, the date of the day is set in, for example, the main storage device (MS) 1a managed by the operating system (OS). Therefore, the date information is taken out from the main memory (MS) 1a and the previous automatic IP
L When the completion date is retrieved from a specific area of the file memory (FM) 4, compare both, and if they match, step
Jump to 120, and if they do not match, move to step 121.

Step 120: It is recognized that there is a re-IPL during the system operation, and only system setup (startup) processing (initial setting processing) is performed in order to retain the system resource immediately before the system down.

Steps 121 and 122: Recognizing the start of operation of a new system, clear the work area of the file memory (FM) 4,
After performing initialization processing such as canceling the output waiting job and resetting the job number, initialization processing for starting up the system is performed.

In any of the above steps 120, 121, 122, when the system starts up, the main storage device (MS) 1a
The current day's date set above is used for the previous automatic IPL.
The date of completion is stored in the specific area of the file memory (FM) 4.

The operations after step 13 are the same as those of the conventional method, and therefore will be omitted.

In the above example, for example, from 8:30 am to afternoon
Although the case where the system is operated until 10:30 has been described as an example, if the system operation period exceeds 0:00 am, the date will be changed during system operation. It is necessary to look at the current time before, and to achieve the comparison logic that outputs the disagreement in step 16 so that the initialization process is performed only when the time is after the start time of the automatic system termination process. For example, the mismatch between the date and the time is detected.

As described above, the present invention adds the function of storing the date of the previous automatic IPL completion time and the means for comparing the previous date and the current day in the initial setting process during automatic operation. The feature is that the mode of the initial setting process is automatically determined.

〔The invention's effect〕

As described above in detail, in the data processing system having the automatic driving mechanism, the initialization processing method during automatic operation of the present invention, when the initialization processing of the system is completed, sets the automatic IPL completion date of the system. After recording, after the automatic IPL of the system, by recognizing the date of the current day and providing a means for comparing this date with the previous automatic IPL completion date, the date of the current day, If the previous date matches, only the initial setting (system setup) processing is performed, and if they do not match, the initialization processing (clearing the work disk, etc.) is performed, and then the initial setting processing is performed. Therefore, the initial setting process during automatic operation can be correctly performed according to the mode of the system, and the system resources can be retained when the system is down. There is that effect.
