If PowerExchange is not capturing changes from a data source on z/OS, verify that the following requirements are met:
The PowerExchange Agent is active.
The PowerExchange Logger for z/OS is active and connected to the PowerExchange Agent.
The ECCR for the data source is active.
The ECCR is capturing change data.
For DB2 for z/OS, IMS, and VSAM sources, check messages PWXEDM172808I and PWXEDM172809I to determine if change data capture is active for each registration and that the ECCR is capturing changes.
For DB2 for z/OS sources, the source tables must be defined with the DATA CAPTURE CHANGES option.
The capture registrations that you created for data sources in the PowerExchange Navigator are correct and active.
The data source is being updated by an application.
