Abstract

PURPOSE:To improve the reprocessing efficiency for a job which is finished abnormally by the competition of resources by setting said job under a remaining state. CONSTITUTION:A terminator 5 outputs a logic ''0'' when the job processing is over with no fault and a logic ''1'' when the job processing is finished abnormally respectively. The logic ''1'' is inverted by an inverter circuit 6 and turned into logic ''0''. Thus the actuation of a job erasing part 7 is stopped, and a control part 3 is actuated via a gate circuit 9. The part 3 lowers the priority of the job down to a desired level for each class. Then this job is made remain within a job cue memory 1.

Description

Detailed Description of the Invention: Technical Field of the Invention The present invention relates to a method for retaining resources of a job when an abnormal termination occurs due to resource contention during processing in a data processing device that executes a job. It is related to.

(bl) Prior Art and Problems Electronic computers, especially data processing devices, are widely used and are effective in processing jobs.

This data processing device inputs jobs using a card reading device or the like, waits them in a job queue according to class and priority, activates an inishake, and executes processing according to the priority of the job queue. Although the resources required to execute a general job are managed in a queue so as not to conflict with each other, conflicts may occur for some reason. At this time, the inishek releases the relevant resources), and if you try to process the failed job again, you will have to activate the card reader and input the job again, which is inconvenient. The drawback was that it slowed down the processing speed.

(C1) In view of the conventional drawbacks, the present invention proposes a resource residual method that can efficiently reprocess jobs that have abnormally terminated due to resource contention. .

+di Structure of the Invention Briefly stated, the present invention provides a data processing device that is equipped with a job queue, a spool file, an initiator, and a terminator and executes job processing. It is characterized by having a function of detecting, a function of causing the resources to be released when the function is activated to remain in the spool file, and a function of making the resources remain in the job queue, so that abnormally terminated jobs remain. That is.

(el　Embodiments of the invention Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

The figure is a block diagram of one embodiment, but does not show the resource retention method of the present invention.

In the figure, 1 is a job queue memory, 2 is an inishake, 3 is a management section, 4 is an execution section, 5 is a terminator, and 6 is a terminator.
7 indicates an inverter circuit, 7 indicates an erase section, 8 indicates a spool file, and 9 indicates a data 1 circuit.

Job power A input from the card reading device is stored in job queue memory 1 as class yJll A I...

B1 . . . , CI . The management unit 3 of the initiator 2 stores jobs in the job queue in order of priority.
It is taken out from the memory 1 and sent to the execution unit 4 to execute the job. The execution unit 4 transmits the execution results to the terminator 5 and cleans up the job processing. terminator 5
For example, if the job processing is completed without any problems, the logical value is ``0''.
If the program terminates abnormally due to resource contention, etc., it operates to output the logical value "1°. Therefore, in the case of normal termination, the logical value "0'' is inverted in the inverter circuit 6 and the eraser 7 is activated. At the same time, the erasing unit 7 instructs the management unit 3 to erase the relevant job from the job queue memory. As a result, the job in question in job queue memory 1 is deleted. Conventionally, the above-described operation was repeated even when the process ended abnormally. In the case of abnormal termination, the present invention sets the logical value "1" to the terminator 5.
is output, the inverter circuit 7 stops the operation of the erasing section 7, and the control section 3 is activated via the gate circuit 9.

The gate circuit 9 is, for example, an AND circuit with one input terminal having a logic value of "1", and is provided for the management unit 3 to distinguish between abnormal termination and normal termination. The priority of the job is lowered and the job is changed to the required priority for each class in the job queue memory 1 and left.

ffl Effects of the Invention As explained in detail above, the resource retention method of the present invention operates the card reading device when a job that has abnormally ended due to resource conflict is left and the job is reprocessed. This allows for efficient reprocessing without any problems.
If applied to a device that processes jobs, it will have many advantages in terms of processing efficiency.
