Control Record

A control record is a job record in the F91300 table. It is named *SCHEDULE and is hidden from the user. The *SCHEDULE record contains information about the state of the Scheduler processes on the server, and it is the method of communicating to those processes.

For example, when the launch loop starts on the server, it sets a flag in this record to indicate that it is up and running. You can end the launch loop by toggling the corresponding end process flag (such as Job Launcher Status or Job Monitor status) from the Form menu on Scheduler Server Control. The next time that the launch loop fetches the control record, it finds the flag, resets both flags, and ends.

If the system does not find the control record when it is fetched, the record is recreated by P91300 when entering the Scheduler Server Control form. In addition, if the record is corrupt, the aforementioned function is called to recreate it. The sleep times for the job monitor are reset to 15 minutes, and the audit information in this record is updated with the user ID set to SCHEDULER.

Note: Beginning with Tools Release 9.2.26.0, the F91301 table is used for scheduler control records. It supports multiple servers and multiple ports on the same server for scheduler kernels.
