Uninstalling the SMF user exit

To uninstall the SMF user exit code from a system, complete this procedure.

Procedure

Stop the System Data Engine.
Remove the SMF user exits that were previously installed. See the following sample MVS™ commands that dynamically remove the exit:
```
SETPROG EXIT,DELETE,EXITNAME=SYS.IEFU86,MODNAME=HBOSMF86
```
If you have installed the SMF user exits on some subsystems, remove the SMF user exits from those subsystems, too. For example, to remove the SMF user exit from the subsystem JES2, run the following commands:
```
SETPROG EXIT,DELETE,EXITNAME=SYSJES2.IEFU86,MODNAME=HBOSMF86
```
Remove the SMF user exit from the system link pack area (LPA) by issuing the following MVS command:
```
SETPROG LPA,DELETE,MODNAME=HBOSMF86,FORCE=YES
```
Stop the Data Streamer.
To free the 2G above-the-bar storage, and other storage spaces that are used by the SMF user exit, run the sample job HBODSPCE.
