Establishing Restart Points for CDC Sessions after a PowerCenter Upgrade

Establishing Restart Points for CDC Sessions after a PowerCenter Upgrade

Before you start CDC sessions after a PowerCenter upgrade, establish restart points.
Prior to the PowerCenter upgrade, you should have saved the restart tokens. If you did not follow the procedure to save the restart tokens prior to upgrading PowerCenter, contact Informatica Global Customer Support for assistance.
To establish restart points for CDC sessions after a PowerCenter upgrade:
  1. Verify that the restart token files for all CDC sessions contain restart tokens.
    Depending on the PowerCenter release you are migrating from, PWXPC stored the restart tokens as follows:
    • If you are migrating from a PowerCenter release earlier than 8.1.1 SP2, PWXPC stored the final restart tokens in the restart token file for the session when the session ended.
    • If you are migrating from PowerCenter 8.1.1 SP2 through SP5 and did not enable enhanced restart, PWXPC stored the final restart tokens in the restart token file for the session when the session ended.
    • If you are migrating from PowerCenter 8.1.1 SP2 through SP5 and enabled enhanced restart, PWXPC stored the restart tokens in a backup restart token file with an appended timestamp when the session recovery operation ended. Copy the backup restart token file for each CDC session to the restart token file for that session.
    • If you are migrating from PowerCenter 8.5 or later, PWXPC stored the restart tokens in the restart token file when the session recovery operation ended.
  2. Cold start the CDC session or workflow.
    PWXPC uses the restart token file to restart the CDC session.
