This is the SMF Step Initiation Exit and it must be enabled for the desired address space types on which Application Performance Analyzer will report. The IEFUSI exit point can be defined to SMF so that SMF will be called for the entire system, batch jobs, started tasks, and TSO logons. Enable IEFUSI by performing the following steps:
SYS(...,
EXITS(IEFUSI,...)) /* enable IEFUSI for the entire system */
SUBSYS(TSO,
EXITS(IEFUSI,...)) /* enable IEFUSI for TSO workloads */
SUBSYS(JES2,
EXITS(IEFUSI,...)) /* enable IEFUSI for JES2 Batch workloads */
SUBSYS(JES3,
EXITS(IEFUSI,...)) /* enable IEFUSI for JES3 Batch workloads */
SUBSYS(STC,
EXITS(IEFUSI,...)) /* enable IEFUSI for Started Tasks */
CAZ1221I CAZ0-MAIN Module CAZ00990 added to exit SYSTSO.IEFUSI
After applying any maintenance or installing a new release of Application Performance Analyzer, do one of the following actions:
SETPROG EXIT,DELETE,EXITNAME=SYS.IEFUSI,MODNAME=CAZ00990
SETPROG EXIT,DELETE,EXITNAME=SYSJES2.IEFUSI,MODNAME=CAZ00990
SETPROG EXIT,DELETE,EXITNAME=SYSJES3.IEFUSI,MODNAME=CAZ00990
SETPROG EXIT,DELETE,EXITNAME=SYSTSO.IEFUSI,MODNAME=CAZ00990
SETPROG EXIT,DELETE,EXITNAME=SYSSTC.IEFUSI,MODNAME=CAZ00990
Then restart the Application Performance Analyzer-started task, which will load the new Application Performance Analyzer exits.
