Starting the IDMS Log-Based ECCR

You can run the IDMS log-based ECCR as a started task or batch job. Usually, the ECCR runs as a started task. Whenever you create or change IDMS capture registrations, you must restart the ECCR to activate those registrations.

Before you start the ECCR, verify that you completed the following tasks:

Configure the IDMS log-based ECCR options.

Configure the IDMS log-based ECCR JCL.

Activate the PowerExchange Agent, Listener, and Logger.

Create capture registrations for the IDMS sources and activate the registrations.

Create and populate the PowerExchange Log Catalog for IDMS logs.

To start the ECCR as a started task, use the MVS START command:

S eccr_task_name

If you set the COLDSTART option to Y in the ECCRIDLP options member, the ECCR cold starts.

If you set the COLDSTART option to N and previously ran the ECCR, the ECCR warm starts from where it left off.

Verify that all of the IDMS logs of interest for CDC processing have been added to the PowerExchange Log Catalog.

When the IDMS log-based ECCR is running, it regularly checks whether logs have been added to the PowerExchange Log Catalog for capture processing. If logs have been added, the ECCR captures the change data from the logs and sends the data to the PowerExchange Logger.
