Speaking for the IIDR CDC for z/OS product, when a refresh, either differential or standard, is performed, any mirroring activity for the subscription is suspended after a final bookmark has been sent to the target. Once the refresh has finished, the mirroring activity is restarted using the bookmark that was last sent. If a differential refresh is used, and "Log Differences" is specified, the situation does not change. Mirroring is not active while the refresh is ongoing.

Subject: Differential Refresh Question
Hi,
Does anyone know if I were to perform Differential refresh on 1 table in a subscription, do the rest of the tables in the subscription continue mirroring based on their last applied bookmark or it will be using the new bookmark from the differential refresh? And also if I were to only perform log differences from differential refresh, will it's bookmark also skip to the latest?
Any help is much appreciated. Thanks
