CICS Db2 statistics

In addition to the limited statistics output by the DSNC DISP STAT command and those output to the STATSQUEUE destination of the DB2CONN during attachment facility shutdown, a more comprehensive set of CICS® Db2 statistics can be collected using standard CICS statistics interfaces:

• The EXEC CICS EXTRACT STATISTICS command accepts the DB2CONN keyword to allow CICS Db2 global statistics to be collected. CICS Db2 global statistics are mapped by the DFHD2GDS DSECT.
• The EXEC CICS EXTRACT STATISTICS command accepts the DB2ENTRY() keyword to allow CICS Db2 resource statistics to be collected for a particular DB2ENTRY. CICS Db2 resource statistics are mapped by the DFHD2RDS DSECT.
• The EXEC CICS PERFORM STATISTICS command accepts the DB2 keyword to allow the user to request that CICS Db2 global and resource statistics are written out to SMF.
