control size of UOW after an alter to rotate partition

requesting that DB2 generate reasonably sized URs when performing a mass delete action against a table with DATA CAPTURE set to CHANGES. in a specific case, we were rotating partitions on a base source table which was being replicated with data capture - but when the Alter table occurs to rotate the partition, the purging of the data is propagated via db2 logs as deletes to the target through CDC. when rotating partitions, you would expect to be able to purge that data without replicating it to target table - however, in our case, it pushed through the entire contents of the partition as a single delete statement to CDC which overloaded it's staging space and brought down our LPAR as it exhausted aux storage because the single UOW was too large to process. need to be able to control the size of the uow as you are replicating deletes from an alter statement that is rotating partitions.

    Dear Nizar, Thank you for submitting this requirement. We believe this is a good idea. It will require coordination between Db2 and another IBM product. We will re-open this idea when both products have this requirement prioritized for delivery in their 12 month forecast.

    Sincerely,

    The Db2 for z/OS Team
