The STATIME_MAIN subsystem parameter specifies the time interval in seconds, for collection of interval-driven statistics not collected at the interval specified by the STATIME or STATIME_DDF subsystem parameters.

- 5–60 (multiples of 5)
- The interval in seconds for writing statistics records for the following IFCIDs:
- 1 (System statistics)
- 2 (Db2 statistics)
- 202 (Buffer Pool Attributes)
- 225 (Storage statistics)
- 230 (Group Buffer Pool Attributes)
- 254 (Coupling Facility Cache statistics)
- 369 (Wait and CPU time aggregated by connection type)
When STATIME_DDF = 0, STATIME_MAIN will also control:- 411 (Remote application statistics based on CURRENT CLIENT_APPLNAME)
- 412 (Remote user statistics based on CURRENT CLIENT_USERID)
Tip:IFCID numbers are often presented in Db2 and its documentation with three or four digits and leading zeros. For example, you might find: "IFCID 1," "IFCID 001," or "IFCID 0001." However, you can assume that these references each have the same meaning.
The statistics records are written at approximately the end of the specified interval.
