REBUILD - After recovery of TS is NPSI improvement

Recovered SEMHNSA Partition 1 which has a NPSI. Rebuild has no idea that only partition 1 was recovered and rebuilds all the partitions for NPSI XEMHUNSA. Believe improvements need to be made to make the REBUILD know that only partition 1 needs to be rebuilt and the non-recovered partitions needs only to be unloaded and loaded back to the NPSI. This should work similar to REORG where only partitions that are being reorged are unloaded/sorted and others partitions in the NPSI are just unloaded.

    When the following is run, REBUILD only does the partitions in the listdef.


    LISTDEF RECOVERX

    INCLUDE TABLESPACE DLOADMB1.SMBMMEE

    PARTLEVEL (616,631,686,742)


    RECOVER LIST RECOVERX

    TOLOGPOINT X'00000000C17235531C14' PARALLEL 4

    REBUILD INDEXSPACE LIST RECOVERX SCOPE PENDING


    When the following is run, the RECOVERY utility will only recover PARTLEVEL (616,631,686,742), but the REBUILD will do all partitions. I was wondering if there was a way to have the information passed from the RECOVER to the REBUILD so that the REBUILD only does the recovered partitions. The information is in SYSCOPY.

    Rebuild step shows every logical part of the NPSI is being rebuilt. Should this be a bug instead of an idea?

    XEME4PR1 and XEME5PR1 are NPSIs and the logical part are in RBDP, but REBUILD does the whole NPSI. I have the whole joblog but don't see how to attach it.

    Thank you for submitting this Db2 Utilities Suite for z/OS enhancement request.

    This requirement is in ‘Need More Information’ status.

    Please answer the following request from the development team:

    Today, after a part level PIT RECOVER is performed on the base table space, the associating logical partition of the NPSI is placed into RBDP for subsequent REBUILD INDEX operation. It is up to the end user to decide whether to only rebuild the needed logical partition(s), or rebuild the entire NPSI. So we are not clear on the need for the proposed enhancement unless there is other reasons not documented for further consideration.

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

    Sincerely,

    Db2 Utilities Suite for z/OS Team
