Dialog Statistics › Setting a Checkpoint Interval

Setting a Checkpoint Interval

The DCMT VARY ADSO STATISTICS command is used to set a checkpoint interval, which determines when the collected statistics are written to the system log, as follows:

• DCMT VARY ADSO STATISTICS CHECKPOINT INTERVAL checkpoint-interval-number specifies that statistics for all dialogs are written to the log once at every checkpoint-interval-number statistics accumulations. Additionally, statistics are written to the log when the application terminates. Note that CHECKPOINT INTERVAL 0 is equivalent to CHECKPOINT INTERVAL OFF.
• DCMT VARY ADSO STATISTICS CHECKPOINT INTERVAL OFF specifies that statistics are written to the log only when the application terminates.

If no DCMT VARY ADSO STATISTICS command with the CHECKPOINT INTERVAL parameter is issued prior to the execution of an application, the runtime system uses the specification established at system generation.
