IEFU83

This SMF Record Exit must be enabled and the recording of SMF record type 120 subtype 9 must be activated, for Application Performance Analyzer to report on WebSphere® activity. The IEFU83 exit point can be defined to SMF so that SMF will be called for the entire system, batch jobs, started tasks, and TSO logons. Application Performance Analyzer only requires that IEFU83 be defined to the SYSSTC exit point. Application Performance Analyzer will define the exit point when WAS=(YES...) is specified on the CONFIG SAMPLE statement.

Enable IEFU83 and activate SMF record type 120 subtype 9 recording by performing the following steps:

Create or update a SMFPRMxx member in SYS1.PARMLIB (or any parmlib that will be used for IPL). Specify 120(9) on the TYPE option, and IEFU83 on the EXITS option of the SYS or SUBSYS(STC) parameters. For example:
```
   SYS(TYPE(120(9)),...,
   EXITS(IEFU83,...)) /* enable IEFU83 for the entire system */

   SUBSYS(STC,TYPE(120(9))
   EXITS(IEFU83,...)) /* enable IEFU83 for started tasks     */ 
```
To make the changes effective, issue the 'SET SMF=xx' console command.

When you set up SMFPRMxx correctly, the Application Performance Analyzer-started task will inform you of each exit point that Application Performance Analyzer is using. For example, if you set up SMFPRMxx to take SMF exit IEFU83 for started tasks then you would see a message similar to the following for SYSSTC:

CAZ1221I CAZ0-MAIN  Module CAZ00993 added to exit SYSSTC.IEFU83

To reload the exit after you apply any maintenance or install a new release of Application Performance Analyzer, complete one of the following actions:

IPL the system and start the Application Performance Analyzer-started tasks.
Ensure that all Application Performance Analyzer-started tasks on your system are stopped, and then restart these tasks.
