The CICS/VSAM ECCR runs in the CICS region. To capture changes, the ECCR uses CICS global user exits (GLUE) and a PowerExchange task-related user exit (TRUE).

The ECCR passes captured changes to the PowerExchange Logger for z/OS. The PowerExchange Logger logs the changes in its log files. PowerExchange, in conjunction with PWXPC and PowerCenter workflows, can then extract the changes from the PowerExchange Logger log files for propagation to targets in near real time.

Review the CDC configuration and management information that is specific to CICS/VSAM data sources. For other implementation tasks, see CDC Implementation Summary. For example, you must create data maps and capture registrations in the PowerExchange Navigator, and define a PWX NRDB connection in PowerCenter.
