For RPN TS, each partition reorged need a separate IC tape drive, need a way to limit the number of tape drives per iteration of REORG for the IC

If 65 partitions of a RPN with NPSIs are being reorg at the same time, 65 IC tape drives would be required. That is excessive and probably all shops can't support that. Even when no NPSIs, this would be a problem. HAA generates LISTPARTS 4096 when there is a NPSI. It does not generate LISTPARTS when a RPN does not have NPSIs. I am purposing adding List RPN Partitions which is separate from List Partitions (non-RPN). List RPN Partitions would probably alot smaller than List Partitions due to the TAPE constraint. Another idea would be able to have HAA be able to support RPN ICs separately on the panels to allow a site to have the ICs going to DASD instead of TAPE.

    Db2 for zOS delivered an enhancement in APAR PI75518 https://www.ibm.com/support/pages/apar/PI75518 to limit the number of DASD or TAPE drives used for inline ICs during REORG.

    The limit can be set globally using a Db2 ZPARM or through a new REORG keyword ICLIMIT_TAPE.


    Db2 Automation Tool supports ICLIMIT_TAPE (and ICLIMIT_DASD) in the "Copy options" section of a REORG utility profile (panel DAJ$UCOP - Image Copy Options)
