7.6.6 Notes on the Interval Control job
The following provides precautions (items you should know in advance) for using the Interval Control job.
Example of jobnets that use the Interval Control job are as follows:
-
Register a jobnet for execution, and execute the succeeding job 30 minutes later.
For details about how to register a jobnet for execution, see 4. Executing an Application in the manual JP1/Automatic Job Management System 3 Overview.
As the wait time for the Interval Control job, you can specify a value from 0 to 1,440 (in minutes).
- Cautionary notes
-
-
The wait time you specify in the Interval Control job is the wait time for the interval control process, not the time from the start to end of the job execution. Depending on such factors as the status of the network at the time, the wait time might not exactly match the time you specify.
-
When the Interval Control job is running and the JP1/AJS3 service is restarted on the host corresponding to the agent running the Interval Control job, measurement (monitoring) of the preset wait time begins after the restart. When the wait time expires, the monitoring condition is satisfied.
Suppose 60 (minutes) is defined as the wait time for the Interval Control job. If the JP1/AJS3 service restarts while the Interval Control job is in the Now running status, the monitoring condition is satisfied 60 minutes after the restart regardless of the time that has elapsed up to the restart.
For the following cases, the job status is the Now running even after the JP1/AJS3 service restarts. Note that if you restart the JP1/AJS3 service during monitoring, the amount of time between execution of the Interval Control job and when the monitoring condition is satisfied is longer than the wait time specified for the job.
- When the Interval Control job defined in a start condition is executed.
- When the Interval Control job is executed from the manager host on which the option to continue execution of active event jobs is enabled.
For details about the option to continue execution of active event jobs, see 8.2.1 Continuing the execution of event jobs if the JP1/AJS3 service stops in the JP1/Automatic Job Management System 3 Administration Guide.
-
If you click Yes in the Expire right after starting section in the Detailed Definition - [Interval Control] dialog box, define the Interval Control job in a start condition, and then register the root jobnet with that start condition for execution while either of the following is true, it might take some time before the start condition is satisfied.
- Many root jobnets with start conditions or jobnets defined with event jobs are registered for execution at the same time.
- Many events are detected.
