    Dear Joseph, Our Db2 for z/OS team has been busy reviewing this Aha! idea and would like you to please elaborate more about the problem itself.

    In the meantime, they have the following comments to share with you:

    1. For UTS, it is a single table per table space. when the table is dropped, the table space is also dropped. Db2 generates catalog update log records to reflect the event. The QREP tool can use log record to recognize the drop table has occurred in the source and take appropriate action in the target object. Even if the table is recreated again with different OBID, it may recreated the same, however it will contain newly added data which is independent from the old data. Should that be treated as different object right ?

    2. If user would like to create object with the same OBID for any reason. The syntax of CREATE TABLE DDL statement provides OBID clause which allow user to specify OBID for the table if OBID has not been reused by other table within the same data base.

    We look forward to hearing from you.

    Sincerely,

    The Db2 for z/OS team
