Max, DB2 is an absolute madhouse from the perspective of dataset allocation. See Scotts post from a few days ago re GRS. *IF* (big IF) you can guarantee that the volumes containing your catalogs are *never* going to be varied online to another system, consider genning them as non-SHARED as Bruce suggests. Think about the share options as well if you decide to go this path. Personally, I consider the potential data corruption too high a risk. The cost of the (non-propogated) RESERVE is not that high IMHO.
