We do this because we tend to backup all the volumes in a storage group "in one fell swoop" using DFDSS. All the datasets which reside in that storage group have an HLQ which relates to the storage group. So, by having the UCAT in the storage group, it is "in sync" with the datasets in that storage group when we do our backups. IOW, the datasets (on DASD) which have a given HLQ will reside in a specific Storage Group (and no other) and so will be cataloged in the UCAT in that Storage Group. > > To answer Sam's question, the system I inherited has all of > it's Ucats on non-SMS volumes and I saw no reason to change > it.

Unfortunately, it was determined that too many catalogues were falling in the cracks and not being backed up at the proper time. -- John McKown Senior Systems Programmer HealthMarkets Keeping the Promise of Affordable Coverage Administrative Services Group Information Technology The information contained in this e-mail message may be privileged and/or confidential.
