Reset statistics regularly at system checkpoint

Unless you have a specific reason for resetting MSC logical link statistics manually, you should configure IMS to reset link statistics regularly at system checkpoint by specifying a reset option of RESET,CHKPT on the type-2 command UPDATE MSLINK.

Automatic reset at system checkpoint is the default reset option that is in effect when IMS restarts.

The longer the interval between resets, the less useful the statistics become for determining problems and other analyses. If you need to run a benchmark or gather statistics for an interval longer than the interval between IMS system checkpoints, you can turn off the automatic reset at checkpoints by issuing the UPDATE MSLINK command with the NORESET,CHKPT parameters.

When automatic resets at checkpoint are turned off, IMS does not reset link statistics, and you must manually reset the statistics to start a new recording interval. Statistics are manually rest by issuing the type-2 command UPDATE MSLINK NAME(linkname) START(STATISTICS) OPTION(RESET).
