MODIFY (F) JES3 commands

JES3 will accept the following MVS™ MODIFY commands:
MODIFY JES3, CHK
The command allows the operator to check the 'health' of the JES3 address space. A summary report is issued to the console listing any unusual conditions found.

The command runs asynchronously to the JES3 address space code. Therefore, it is possible that JES3 is changing the data while the command is executing.

This can lead to an occasional program check or a loop while the command is executing. When a loop is detected, message "IAT6417 Command 'CHK ' exceeded 1 minute. Reply 'CANCEL' to stop" is issued and a response is required. In either case, enter the command again. If the error happens persistently, you can report the problem to IBM®.

MODIFY JES3, INT=n
This command allows changing of the Monitoring interval for the Wait and Loop monitor. n specifies the interval in seconds. The default value is 10 seconds. The maximum value is 59940 (999 minutes).

The interval specification controls how frequently JES3 will check what the currently dispatched FCT is.

MODIFY JES3, THRSH=n
This command allows changing of the Monitoring threshold for the Wait and Loop Monitor. n specifies the threshold in seconds. The default value is 30 seconds. The maximum value is 300 seconds.

The threshold determines when messages IAT6397, IAT6398, IAT6415 and IAT6410 are issued for an FCT that has been continuously active for the specified number of seconds.
