Triggering Reintrospection
You can set up a trigger to reintrospect based on a JMS event, a system event, timer event, or user-defined event. See Triggers for more information about triggers.
To set up a reintrospection trigger
1. Create a new trigger:
a. Right-click in the Studio resource tree where you want the trigger to reside.
b. Type a name for the new trigger and click OK.
2. Specify the condition that is to invoke the trigger: JMS Event, System Event, Timer Event, or User Defined Event.
3. For Action Type, select Reintrospect Data Source.
4. Specify the data source in one of these ways:
Type the resource-tree path and data source name in the Data Source Path field.
Click Browse and in the Select a datasource dialog box navigate to the data source, highlight it, and click OK.
5. Optionally, specify email information (in the To, Cc, Bcc, Reply-To, Message Subject, and Message Body fields) to send email when the trigger fires.
6. Select one or both of these options:
Do Not Persist Detected Changes—If you do not want to persist detected changes.
Do Not Send If No Changes Detected—If you do not want email sent if no changes were detected.
7. Check Enable Trigger near the top of the panel to enable this trigger.
8. Use Studio Manager to track the status and history of when this trigger runs.
