CICS operational statistics (CMRSTATS)

CICS statistical records are first written to the system management facility (SMF) data set with CICS SMF 110 records. Statistical records can then be reformatted to CMRSTATS records by the CMRSTATS batch routine.

The following figure shows how CICS statistical records are processed for batch reports.

CICS statistical records

Predefined statistical reports select data from the CMRSTATS data set. If you want to create CICS SMF or other third-party vendor reports from data held in the SMF data set, you must first filter out MainView for CICS statistical records. A sample member named CMRSTATX located in your BBSAMP data set removes MainView for CICS records, leaving SMF 110 records for other reports.

All statistical records contain a field in the header area that identifies the record type. Records are selected from the CMRSTATS data set by the two-digit hexadecimal code entered into the TYPE field of the record. Global Performance records (Type CC) are written to the data set at five-minute intervals. Other types of records are written according to the startup parameters specified in the CMRSOPT table.
