Abstract

PURPOSE:To judge the no response of an opposite job at optimum time and to make a whole system efficient by permitting a job on a supervising side to judge no response with elapse time as a reference by means of considering the state of a supervised job at the same time. CONSTITUTION:A job supervisory means 21 which exists in a slave job 2 and which supervises the job state of the slave job 2 including a transmission waiting state from a master job 1 and a transmission preparing state for the master job 1, and packet transmission/reception means 11 and 24 transmitting/receiving data between the jobs 1 and 2 are included. A response transmission means 25 existing in the slave job 2 and transmitting the job state of the slave job 2, the job name of the slave job 2 and a sequence number to the master job 1 after prescribed time which is uniquely decided in the program elapses after the transmission/reception of a packet is included. Furthermore, the system is composed by including a termination notice means 23 transmitting the packet of processing termination notice when a processing terminates and a no response supervisory means 14 which exists in the master job 1 and which judges no response from time which is uniquely decided in the program and from the job state of the slave job 2 included in the transmission packet from the slave job 2. Thus, no response judgement time can be judged in optimum time.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a non-response monitoring method in a multi-job system in which a plurality of jobs operate simultaneously in relation to each other to constitute one system.

[Conventional technology]

Conventionally, the non-response monitoring method in this type of multi-job system has been to check whether the parent job returns a response from its child jobs, and if it is in a state where a response must be returned, the connection with the previous corresponding job is The system compares the time of transmission and reception with the current time and determines that there is no response if the non-response determination time set at the time of starting the family job has passed.

[Problem to be solved by the invention]

As mentioned above, in the non-response monitoring method in conventional multi-job systems, the parent job automatically decides to not respond. the state of dependence,
No-response is determined using the same criteria as for abnormal conditions such as loop processing within the job itself. Therefore, if the non-response judgment time is set too long, if the own job falls into a loop process, it will not notice it for a long time and there will be a lot of waste, and if the non-response judgment time is set too short, it will depend on external processing. There is a drawback that if the control is handed over to the user and the control is not returned for a long time, there will be an inconvenience that no response will be made even though normal processing is in progress.

[Means to solve the problem]

In the non-response monitoring method in the multi-job system of the present invention, a plurality of jobs operate in conjunction with each other to realize one function, and a parent job on the monitoring side and a child job on the monitored side operate in a fixed period of time. In a non-response monitoring method in a multi-job system divided into jobs, job monitoring means exists in a child job and monitors job states of the child job including at least a state of waiting for transmission from a parent job and a state of preparing for transmission to the parent job. , a packet transmitting/receiving means for transmitting and receiving data between jobs, and a packet transmitting/receiving means that exists in a child job and controls the job status of the child job by automatically passing control after a certain period of time uniquely determined within the program after transmitting and receiving packets. a response sending means that sends the job name and sequence number of the child job to the parent job; a completion notification means that exists in the child job and sends a processing end notification packet when processing ends; The non-response monitoring means is configured to determine non-response based on a time uniquely determined within the program and the job status of the child job included in the packet sent from the child job.

〔Example〕

Next, the present invention will be explained with reference to the drawings.

FIG. 1 is a configuration diagram of an embodiment of the present invention, showing a case where a multi-job system is composed of two jobs: a parent job 1 that monitors non-responses, and a child job 2 that monitors non-responses. ing. The job status monitoring means 21 is a means for updating the contents of the job status information storage area 22 when the status of the child job 2 changes. The end notification means 23 sets a job identifier and end notification information in a packet, and causes the packet transmission and reception means 24 to send the packet to the parent job 1.
is an area attached to a job that can be written to by any job, and when data is written to that area, a packet using a mailbox between jobs is notified that the job that owns that area has been written to. It is a means for transmitting/receiving information. The response transmitting means 25 is configured so that the child job, at its initial processing stage, is set to an appropriate time that is larger than the non-response judgment reference time b1 in the response preparation state and smaller than the non-response judgment reference time b2 in the user processing state and the external entry/exit mountaineering state. After time e1 has elapsed, control is passed in the middle of another process, and the job name, sequence number, and job status read from the job status information storage area 22 of the child job are sent to the packet transmitting/receiving means 24. This is means for transmitting to the parent job 1 via the parent job 1. The last response time storage area 12 is an area for storing the time when a packet was last received from the child job 2, and the job status information storage area 13 is an area for storing the time when a packet including the job status was received from the child job 2. This area is updated and stored according to the job status. The non-response monitoring means 14 is configured so that the parent job, which operates asynchronously with the packet transmission operation of the child job, is called at an interval e2 uniquely set within the parent job, and the job status of the child job and the last packet reception time are monitored. This is a means of checking for non-response from the system.The criterion for determining non-response is input as a parameter, and the non-response judgment criterion time bl is used for the response-preparing state. For these two states, the non-response judgment reference time b2
is used.

FIG. 2 is a flowchart of the processing of the no-response monitoring means 14, and the processing of the no-response monitoring means 14 will be explained with reference to FIG. This means is a subroutine in which control is automatically handed over even during the processing of the parent job when a certain time e2 has elapsed from a certain timing, and when the means ends, the original processing returns again. The status of the child job is checked in the job status information storage area 13 from step ■ to step ■, and if response work is in progress, step ■ returns to step ■.
Then, it is checked whether a certain period of time has elapsed from the last transmission/reception time to the current time, and if it has elapsed, the job status of "no response" is stored in area R at step (2). The parent job refers to area R and performs no-response processing according to the processing of the parent job. Also, if the job status of the child job is in user processing or external input/output, check whether a certain amount of time has elapsed from the last sending/receiving time to the current time after step ①. , if it has elapsed, the job status of "no response" is stored in area R at step (3). If the time has not elapsed in step ■, the job status is stored in area R as “No response” in step ■.Finally, in step [phase], the call time e2 is set so that this procedure is called again. Declare to the system.

FIG. 3 is a flowchart of the processing of the response transmitting means 25.
The operation of the response transmitting means 25 will be explained with reference to FIG. This method is used for a certain period of time e]
When the time has elapsed, control is automatically passed even during the processing of the child job, and in the subroutine that returns to the original processing at the end of this means, the job status of child job 2 is sent to parent job 1. This is to notify that job 2 is running without abnormally ending. First, in step ■, job status information is set in the transmission packet from the job status information storage area 22, in step @, the job name and sequence number of the child job are set as the packet identifier, and in step ■, the packet transmitting/receiving means is set. call and send a packet. Finally, the call time e1 is set so that this means is called again in step [stock].

〔Effect of the invention〕

As explained above, the present invention realizes functions in relation to each other, and in a multi-job system in which a job on the monitoring side and a job on the monitored side exist, the status of the job to be monitored is also taken into consideration at the same time. The job on the monitoring side judges whether there is no response based on the elapsed time, so the child job does not operate independently but with an interface with the user, or the child job is connected to an external file. Even if there is a process that requires a lot of time for input/output, it is possible to determine whether the other job is not responding in an optimal time, and this has the effect of increasing the efficiency of the entire system.
