Verifying That Basic CDC Requirements Are Met

Verifying That Basic CDC Requirements Are Met

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.
