Point-in-Time Recovery

Point-in-time recovery invalidates the change data that the PowerExchange Logger logged and that the batch job recorded.

Standard point-in-time recovery does not indicate that the PowerExchange Logger data is invalid to the processors of that data.

A processor of PowerExchange Logger data must perform the following processing if you need to use point-in-time recovery:

Recover the source to the correct point-in-time.

Recover the target to the correct point-in-time. This recovery might require rematerialization of the targets. If you use PowerExchange Condense, wait until the Condense process captures all outstanding changes from the PowerExchange Logger. Then regenerate the restart tokens for the PowerCenter CDC sessions that update the targets.

Reset the change processor to restart processing when the recovery is complete.
