Enabling Periodic Exception Processing

Periodic Exception Processing analyzes system metrics and compares them against predefined thresholds, user-defined thresholds, and application metrics. When a threshold is exceeded, an event exception is shown. Configure using the Configuration Manager or PARMGEN. If you configure Periodic Exception Processing, the function is started automatically at startup of the OMEGAMON Collector.

About this task

You can use Periodic Exception Processing in the following ways:
  • Configure Periodic Exception Processing. In this case, the function is started automatically at startup of the OMEGAMON Collector. One common set of threshold definitions is used for all users.
  • Start Periodic Exception Processing manually after you start Performance Expert Client. In this case, you do not need to configure the function. You can define a set of threshold definitions for each user ID.
  • You can use the Exception Processing user exit that issues messages to the operator console in case of exceptions.

Procedure

Set parameter KD2_PFxx_AEXCP_D2PYACT to Y.

What to do next

  1. After you configure the component, allocate operational data sets. See Completing the configuration.
  2. In addition, you must provide threshold definitions in the threshold data set. Before you can use Periodic Exception Processing, you must allocate additional runtime data sets first to allocate the Threshold Exception data set, and then copy the default threshold definitions.
