Resetting statistics counters

Statistics counters are reset in the following circumstances:

v

At CICS startup

v

When interval statistics are written (but not when an interval occurs and no
statistics are written)

v

At end of day

v

When requested reset statistics are written.

However, you can cause statistics counters to be reset without writing records to
the SMF data set. You do this by changing the statistics recording status, using
either of the commands:

v

CEMT SET STATISTICS ON|OFF RESETNOW

v

EXEC CICS SET STATISTICS ON|OFF RESETNOW.

Note that it is valid to specify the RESETNOW option only when there is a genuine
change of recording status. For example, coding EXEC CICS SET STATISTICS ON
RESETNOW when STATISTICS is already set ON causes an error response.
