9.3.1 Create or Edit Chain

This section describes how to create or edit a chain.

To create a chain, Database Actions internally uses the DBMS_SCHEDULER.CREATE_CHAIN procedure.

1. In the Chains page, at the top right, click Create Chain.
2. In Properties, enter the following fields:
   • Name: Name to assign to the chain.
   • Evaluation Interval: NULL reevaluates of the rules of a running chain only when the job starts and when a step completes. A non-NULL value causes rule evaluations to also occur periodically at the specified interval.
   • Enabled: Enables the chain. (Causes the DBMS_SCHEDULER.ENABLE procedure to be called after the chain is created.)
3. Click Create to create the chain.

   Click Create and Open to create the chain and open in Diagram mode.
