Migrating an ESDS Data Set from VSAM Batch CDC to CICS/VSAM CDC

If you previously used PowerExchange batch VSAM CDC to capture change data from VSAM ESDS data sets, you can migrate these data sets to CICS/VSAM CDC to capture change data records in an online CICS Transaction Server environment.

Perform the following migration steps:

In the PowerExchange Navigator, create a capture registration for the source ESDS data set.

Verify that the RDO definitions for the CICS fields that are associated with the registered ESDS data set are defined with RECOVERABLE(BACKOUTONLY) or RECOVERABLE(ALL) option.

Define CICS/VSAM ECCR override options, as needed, in the //EDMKOVRD DD statement of the CICS startup procedure or in the data set to which this DD statement points. To capture data from ESDS data sets, you must at least define the CAPTURE_ESDS=ON option.

Restart the CICS/VSAM ECCR in one of the following ways:

Restart the CICS region.

Issue the EDMC RESTART command.

Issue the EDMC REFRESH command.
