Non-Sorting, online way to encrypt Db2 Datasets

Currently to encrypt Db2 datasets in an online fashion we use the REORG SHRLEVEL CHANGE. For large tablespaces, or well-organized tablespaces, this incurs the cost of reorganizing (sorting mostly) that we would rather not have just to encrypt. We would like a function of the reorg (or some other utility as there wouldn't be any reorganizing) that performed just a copy to the shadow datasets so that the datasets would be encrypted, in an online fashion (log/switch phases, etc).

    Dear Jeremy, Thank you for submitting this Db2 Utilities Suite for z/OS enhancement request. After careful review and consideration, development has provided their feedback as follows:

    The Db2 REORG utility relies on individual record/key processing for log apply and online availability, and we are not aware of other solution at the data set management level like FlashCopy that can be used to enable or change the encryption key without an outage. Instead, there is a continued focus in the Db2 roadmap to improve and to lower the cost of running the REORG utility, which will provide further relief in this type of encryption enablement scenario.

    We appreciate your input to the Db2 Utilities Suite for z/OS development team. And we hope that you will continue to submit enhancement suggestions for improvements as customer feedback is a key component to shaping the future direction of Db2 Utilities Suite for z/OS.

    Sincerely,

    The Db2 Utilities Suite for z/OS team
