On a z/OS system, the PowerExchange Agent verifies capture registration information, provides registration information to some types of ECCRs, and manages global queues and data flow among CDC components.
The PowerExchange Agent provides capture registrations to the following ECCRs:
Db2 for z/OS
IMS synchronous
Batch VSAM
CICS/VSAM
Other ECCRs read capture registration information directly from the CCT data set. For all of the ECCRs, the PowerExchange Agent verifies the capture registration information.
The PowerExchange Agent also manages global queues and data flow among various PowerExchange CDC components.
Use of the PowerExchange Agent is required for CDC on z/OS.
