Preventing ABARS ABACKUP processing from including multivolume BDAM data sets

DFSMShsm ABACKUP invokes DFSMSdss to process level-0 data sets in the INCLUDE list. During ARECOVER, DFSMSdss is unable to recover multivolume BDAM data sets. To prevent ABACKUP from processing such data sets, issue the following patch:

PATCH .ABRCB.+A8 BITS(.....1..)

If this patch is set, ABACKUP bypasses all multivolume BDAM data sets and continues processing. The reason why ABACKUP bypasses both SMS-managed and non-SMS-managed multivolume BDAM data sets is that you could direct a non-SMS-managed multivolume BDAM data set to be SMS-managed at the ARECOVER site, and DFSMSdss would fail to recover the data set.

Note: This patch should not be used unless your installation has multivolume BDAM data sets in its INCLUDE list, because an extra OBTAIN is needed to identify and bypass these data sets; the OBTAIN will impact ABACKUP’s performance.
