Biggest problem I see with multiple master catalogs is that you have to keep entries in synch. First time you debug a weird problem resulting from out-of-synch catalogs, I think you'll want a single one.
As for installing software maintenance, you should alternate between (at least) two sysres volumes. Swap from one to the other to migrate software upgrade. In case of problems, fall back to the older level. Sysres data sets are cataloged like this: VOLSER------------****** DEVTYPE------X'00000000' This will resolve to the volume you IPLed from on each system. . .

It doesn't mean I was looking in the correct manuals it just means that what I had been told may not be 100% accurate. The manuls do seem to IMPLY that a shared master catalog is the way to go but there is nothing recommending one over the other that I can see. ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN
