Couldn't you define a very small 3390 volume for this purpose in the storage subsystem so that at least you're waste is less

I tried to APAR it years ago, and didn't get very far, so I gave up. The answer I received was that it would make major changes in how the RACF database management logic works on z/OS, so they didn't want to change it. > Isn't that an overkill of dedicating two full 3390 addresses (5 GB) for 2 > x > 17 cylinder of data, the size of the database?? Yes. That's just the way RACF works, AFAIK. It's a waste, but c'est la vie. > Could I put the Primary and the Backup at least on the same volume? Kind of defeats the point if the physical volume chokes for some reason. You should have the Backup on a different physical volume.
