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.

In the Chains page, at the top right, click Create Chain.
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.)
Click Create to create the chain.

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