Description

The present invention relates to a job activation control method, and more particularly, to a job activation control method for efficiently operating a data processing system in an electronic computer room.

[Conventional technology]

In the data processing system, the work given to the system by the user is accepted as a job, a plurality of programs constituting the job are processed as tasks, and the execution of one unit of the job is completed. The data processing system receives a plurality of jobs and sequentially processes the received jobs. Jobs have various forms such as batch jobs, online jobs, and remote batch jobs.

A batch job is a job in which a plurality of jobs are put together and processed collectively. In this batch job, the jobs accepted by the operator in the computer room are sequentially activated to proceed with the processing.

As a known document related to job activation control, there is JP-A-62-150455. This is a job starting method in which a job is started from a workstation as a terminal device.

[Problems to be solved by the invention]

By the way, among the operations of the operator in the operation management work of the computer room, one of the important ones is the job start control work. The job activation control work is performed manually by an operator in the computer room. Since this work is a manual work, there is a problem that the end time of the preceding job cannot be properly determined, the start control of the subsequent job is delayed, and the operation of the computer room cannot be performed efficiently.

Also, when the batch job ends, the message of the batch job processing result is output for inheriting the information.
Up to now, no consideration has been given to collecting the message output by this batch job and connecting it to the startup control of the subsequent job. As described above, since the information is succeeded to the succeeding job by the intervention of the operator, the data processing system cannot be efficiently operated.

The present invention has been made to solve the above problems.

It is an object of the present invention to provide a job activation control method for efficiently operating a data processing system in an electronic computer room.

The above and other objects and novel features of the present invention will be apparent from the description of this specification and the accompanying drawings.

[Means for solving problems]

In order to achieve the above object, in the present invention, data having a processing device, basic software for performing data processing, and a monitor program for receiving a job, managing the progress of the data processing, and controlling the execution of the job In a data processing system equipped with a processing device and an external storage device for storing data, the message output routine of the basic software picks up a message output after the start of execution of a job, informs the monitor program, and outputs the message. Is compared with a message registered in advance, and if the same message exists, a job having the message as a start condition is searched and the searched job is started.

[Action]

According to the above means, in the data processing system, the message exit routine of the basic software picks up the message output after the start of the execution of the job and informs the monitor program. If the same message exists by comparing the output message with the message registered in advance, the activation instruction flag is set. Then, the monitor program searches for a job having the message as a start condition, and starts the corresponding job found.

As a result, it becomes possible to control the activation of the succeeding job by the message output from the preceding job, and to automatically activate the job by the network control of the job by the output message. Therefore, it is possible to reduce the job starting machine operations of the operator in the computer room, and it is possible to efficiently operate the data processing system in the computer room.

〔Example〕

An embodiment of the present invention will be specifically described below with reference to the drawings.

FIG. 1 is a block diagram illustrating the configuration of job activation control in a data processing system according to an embodiment of the present invention. In FIG. 1, 1 is basic software, 2 is a message exit routine, 3 is a waiting message table (WMT), 4 is a monitor program including a job start processing routine, 5 is an operator console, and 6 is started next. It is a succeeding job.

The basic software 1 is a program set including a plurality of programs that perform data processing, a control program such as an operating system (OS) that performs system control, and the like. Also, the basic software 1 includes a routine for outputting a message of a job, and when outputting a message from a job, the message exit routine 2
Is output via. The output message is displayed on the display screen of the operator console 5 and accumulated in the waiting message table 3. Further, the monitor program 4 includes a job activation processing routine,
It is a program that automatically starts the jobs that make up a user's work according to a computer schedule.

The job activation control here is controlled by a message output from the job according to the result of the operating system (OS) activating the job. That is, when a series of activation of the preceding job is completed and the message from the job requested to be output to the OS is output on the display screen of the operator console 5, the message exit routine 2 receives the message. When the message exit routine 2 receives the message, it waits for the message table (WM) in the pageable system work area (CSA).
T) Message 1 to message m registered on 3
And the output message is compared. When the message contents match as a result of the comparison, the message exit routine 2 notifies the monitor program 4 by setting a flag indicating the output of the corresponding message. When the monitor program 4 receives the job activation instruction by the output message comparison, it activates a job activation routine, retrieves the scheduled job, and activates the retrieved succeeding job 6.

FIG. 2 is a block diagram for explaining the processing flow of the job activation control process in the monitor program as a specific example. This job activation control process is notified to the monitor program 4, and the monitor program 4 is activated and the process is executed for the job scheduled in the monitor file 11 as a job activated by message comparison.

When the monitor program 4 is started, the monitor program 4 inputs the job information already scheduled from the monitor file 11 and executes the start processing routine 12. The start processing routine 12 stores the scheduled job information “JOBA, # JJ081I” in the job information table (MJT) 13 and the waiting message table (WMT) 3 on the memory. Next, the process control is transferred to the job activation processing routine 14. Job start-up processing routine 14
Starts the "JOBA" of the succeeding job 6 designated from the waiting message according to the information in the job information table (MJT) 13. By performing such a series of processes, the startup control of the succeeding job 6 is sequentially performed.

That is, for example, when the job "JOBA" waiting for the message "# JJ081I" is scheduled, the following process is performed.

(1) The start processing routine 12 of the monitor program 4 sets the waiting message “# JJ081I” in the waiting message table (WMT) 3 and also the job information table (M
In JT) 13, set the job name "JOBA" and the WMT entry number "4". The entry number "4" is the entry number of WMT3 in which the waiting message "# JJ081I" is set.

(2) Job startup processing routine 14 of monitor program 4
Searches the job information table (MJT) 13 for the job by the waiting message.

(3) In the job activation process, check the activation conditions for JOBA. At this time, the waiting message table (WMT)
It is confirmed by a routine (not shown) of the monitor program 4 that the job start instruction flag of the entry number "4" of 3 has been set to "1" and the waiting message has been output. Start "JOBA".

By the way, the message exit routine 2 here is a user-own coding routine provided for controlling a message output to the operator console 5. The monitor program 4 uses the message exit routine 2 to receive a message output by executing a job. For the received message, a flag indicating message output is set on the waiting message table (WMT) 3, and the monitor program is collectively notified that the message as the waiting condition has been output.

FIG. 3 is a block diagram for explaining another processing flow of the output message communication process in the message exit routine as a specific example. In the output message communication process of this example, a flag indicating message output is set on the waiting message table, and the monitor program is collectively notified that the messages that are in the waiting condition have been output.

This is the message exit routine, as shown in FIG.
This is realized by providing a processing step 22 for setting a flag indicating a message output in 20. That is, in the message exit routine 20, in processing step 21,
The message output from the job is compared with the message already registered in the waiting message table 30, and if the comparison results are the same, processing step 22 is executed. In process step 22, a process for setting a start instruction flag 31 indicating a message output for job start control in the waiting message table 30 is performed for the matched message.

For example, when the message 25 of "# JJ081I" is passed to the message exit routine 20, the messages are sequentially compared from the first entry of the waiting message table (WMT) 30 for comparison (processing step 21, 2
3). Here, since the message 25a registered in the fourth entry of WMT30 matches the passed message 25, the start instruction flag 31 is set (processing step
twenty two). Further, each entry of the following WMT 30 is compared with each other one after another, and the process is repeated until the final entry m of the WMT 30 is compared, and the process ends.

In this way, by setting the activation instruction flag indicating the message output on the waiting message table, it is possible to collectively notify the monitor program that the messages that are in the waiting condition have been output.

As described above, according to the present embodiment, by collecting the message output by each job of the batch job, comparing it with the message registered in advance, and connecting to the activation of the subsequent job, the data processing system by the operator It is possible to reduce the machine operation for job activation in. The data processing system can be operated efficiently.

The main points of the job activation control method based on the output message of the present embodiment described above can be summarized as follows.

(1) The message exit routine of the basic software picks up the message output by the job, compares the message with a previously registered message, and sets the start instruction flag if the same message exists, and sets the monitor program Contact.

(2) The monitor program searches for a message in which the start instruction flag is set, and searches for a job whose start condition is the message.

(3) The monitor program starts the relevant job found.

(4) For example, a "WTO message" or a "WTOR message" output from the batch job is passed to the message exit routine (user own coding routine) of the basic software.

(5) Further, in the message exit routine, it is compared whether or not the message is equal to a pre-registered job activation waiting message, and if they are equal, the activation instruction flag is set, and the monitoring instruction program is collectively set by setting the activation instruction flag. You can also contact them.

(6) In this case, when the monitor program receives the message from the message exit routine, it searches for a job that has the message as a start condition and starts it.

(7) Job activation by such an output message
It is possible to use one output message as the starting condition for multiple jobs. Therefore, fine-grained network management is performed by the output message of the job, and job start control can be realized.

The present invention has been specifically described above based on the embodiments,
It is needless to say that the present invention is not limited to the above-mentioned embodiments and can be variously modified without departing from the scope of the invention.

〔The invention's effect〕

As described above, according to the present invention, it becomes possible to control the job activation control executed in the data processing system by the message output by another job, and the network control between jobs can be realized. As a result, it is possible to reduce the number of job startup operations performed by the operator in the computer room. Further, it is possible to automatically start the job by network control by the message of the job, which has an effect of reducing an error caused by an operator's manual work.
