Working With System Image Definitions › Define a Resource to a System Image › Implement the State Change Exits

Implement the State Change Exits

Some resource classes let you specify state change exits through processes. You can specify two types of exit processes:

• A process that executes before the starting method specified on the Activation Details panel is performed.
• Processes that execute when specified state changes occur. For example, if a resource fails, you may want to invoke a process that writes a problem report. You can specify a process to execute when the actual state, the desired state, or the logical state of the resource changes.

To implement the state change exits for the resource

1. Press F8 (Forward) from the Status Monitor Message Details panel.

   The State Change Exits panel appears.

2. Specify the required exits.

   The specified information is saved when you save the resource definition.

Example: Failure Exit

The following panel shows an example in which the State Change Exits panel specifies that a process be executed when the resource fails:
