IEFU84

This SMF Record Exit must be enabled and the recording of SMF record type 101 must be activated, for Application Performance Analyzer to report on DB2® accounting activity. The IEFU84 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 IEFU84 be defined to the SYSSTC exit point. Application Performance Analyzer will define this exit point when DB2I=(YES,SMF=YES...) is specified on the CONFIG SAMPLE statement.

Enable IEFU84 and activate SMF record type 101 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 101 on the TYPE option, and IEFU84 on the EXITS option of the SYS or SUBSYS(STC) parameters. For example:
```
   SYS(TYPE(101),...,
   EXITS(IEFU84,...)) /* enable IEFU84 for the entire system */

   SUBSYS(STC,TYPE(101)
   EXITS(IEFU84,...)) /* enable IEFU84 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 IEFU84 for started tasks then you would see a message similar to the following for SYSSTC:

CAZ1221I CAZ0-MAIN  Module CAZ00994 added to exit SYSSTC.IEFU84

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.
