CA IDMS Tuesday Tip by Edward Gorga, Principal Support Engineer for September 24, 2013.

The statistics interval is initially set in the SYSGEN by the STATISTICS INTERVAL parameter of the SYSTEM statement. From IDMS 18.0 you can also specify that statistics be written to the log and cleared at a specified time and day interval using the new ROLL TIME and FREQUENCY parameters in the SYSTEM statement.

The DCMT VARY STATISTICS command can be used to dynamically change the statistics interval as well as the new day frequency (ROLL FREQUENCY) and time (ROLL TIME).

Here are some examples of the DCMT command:

DCMT VARY STATISTICS INTERVAL 31600 - Varies the interval at which statistics are written to the IDMS log in seconds.

DCMT VARY STATISTICS ROLL FREQUENCY 10 - Varies the number of days interval at which statistics are written to the log and reset.

DCMT VARY STATISTICS ROLL TIME 22:00 - Varies the time of day at which statistics are written to the log and reset.

DCMT VARY STATISTICS ROLL TIME 22:00 FREQUENCY 10 - Varies both parameters in one command.
