Exception processing user exit

OMEGAMON® XE for DB2® PE supports a user exit to enhance the exception processing capabilities. This exit can handle periodic exceptions and event exceptions. Therefore, you can start the exception user exit for periodic processing, event processing, or both, depending on which kind of exception processing you have activated in the Exception Processor panel.

You can activate the user exit together with periodic exception processing, event exception processing, or both. But you can also activate it when periodic exception processing, event exception processing, or both are already active.

To activate the user exit, type any character in the User Exit field. To deactivate the user exit, enter a blank in this field. The User Exit field is displayed only if the data collector is active.

Several users can invoke periodic exception processing or event exception processing simultaneously using different threshold data sets. The users can start or stop this user exit independently. The user exit routine can check for the user ID, the exception field name, the field value, or other characteristic items to select individual paths of processing.

OMEGAMON XE for Db2 PE provides a sample of the exception processing exit, called DGOMUPXT, which issues a message to the operator. The message text varies depending on whether the situation is an event exception or a periodic exception. For a description of the different formats of this message, see message number DGOV0100I in Messages.

You can modify DGOMUPXT according to your needs, for example, to examine the type of exception and perform any action necessary to handle the situation.
