DCMT VARY STATISTICS Parameters

broadcast-parms

Indicates to execute the DCMT command on all or a list of data sharing group members.

Note: For more information about broadcasting and broadcast-parms syntax, see the section How to Broadcast System Tasks.

INterval

Varies the interval at which statistics are written to the DC/UCF log file.

The statistics interval is initially established at system generation time by the STATISTICS INTERVAL parameter of the SYSTEM statement.

interval-number

Specifies the number of real-time seconds in the new statistics interval.

OFF

Directs DC/UCF not to collect statistics based on a time interval.

ROLl

Varies the interval at which statistics are written to the log file and reset.

TIMe interval-roll-time

Specifies time of day in twenty-four hour format (HH:MM) format at which statistics are written to the log and reset. The time is interpreted as local time.

If you change the local time while Statistics Interval Roll is active, the interval will continue to be every 24 hours from the local time originally used as input. This means that after a time change, such as to daylight savings time, the statistics will run an hour later or earlier in local time. If you want to reset the statistics so that they run at the original local time, you must either restart your system, where the interval will be reset based on the values in the SYSGEN, or use the DCMT VARY STATISTICS ROLL TIME HH:MM command to reset the interval to the local time.

FREquency day-frequency

Specifies the day frequency at which statistics are written to the log and reset.

NOROLl

Varies the system not to perform statistics interval roll.

TRANsaction ON

Enables collection of transaction statistics for all tasks.

Transaction statistics collection is initially enabled at system generation time by the STATISTICS TRANSACTION parameter of the SYSTEM statement.

TRANsaction OFF

Disables collection of transaction statistics for all tasks.

Transaction statistics collection is initially disabled at system generation time by the STATISTICS NOTRANSACTION parameter of the SYSTEM statement.
