Customizing and activating user exits
User exits are predefined exit points where a user-written routine can be given control.
On completion of the user-written routine, control is returned to the program. OMEGAMON for Db2®
Performance Expert supports the following three user exits:
- Exception processing exit
- Use exception processing exits to handle periodic exceptions and event exceptions. For information, see Exception processing exit.
- Db2 authorization exit
- Use the Db2 authorization exit (KD2_OMPE_DB2_EXIT) to overwrite/replace the Db2 authorization module DSN3@ATHB2 with a user exit that you can write and customize.
- User authorization exit
- Use the user authorization exit (KD2_OMPE_DB2_USER) to implement additional authorization checking on the data delivered by Db2. By using this method, you can control which users have access to specific Db2 data at a granular level.
