PWXUCREG utility

PWXUCREG utility

A PowerExchange utility that you can use to suspend one or more capture registrations temporarily so that the PowerExchange ECCR does not capture database changes using those registrations during the suspension period. The utility can also reactivate suspended registrations to resume change data capture, display registration status, and skip change records based on timestamps when registrations are first activated.
This utility runs only on z/OS systems and processes registrations only for the following ECCR types:
  • Adabas ECCR
  • Datacom table-based ECCR
  • IDMS log-based ECCR
  • IMS log-based ECCR
Use the utility to perform the following tasks:
  • Suspend capture registrations to temporarily stop change capture activity for registered sources during the suspension window.
  • Reactivate suspended capture registrations after a suspension to resume change data capture.
  • Display the status setting for capture registrations to verify a status change.
  • Skip all change records in the change stream that have timestamps earlier than the current system time when starting change capture for a registration that has been activated for the first time from the PowerExchange Navigator.
