All of my Sysplexes each have a shared single MCAT per plex. Setting up a Sysplex is probably where the recommendation to a single MCAT is located. In an emergency the LOADxx can be edited to point to any other MCAT and they will all serve to get a system up and running. Additionally in each physical Data Center we have a 3 pack Rescue system (built from Mark Zeldens sources - Thanks Mark !) that normally lives somewhat back level to ensure new maintenance etc. doesn't also render the system unusable.
I wouldn't try to run a complex Sysplex with multiple Master Cats.

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 ________________________________ Warning: All e-mail sent to this address will be received by the corporate e-mail system, and is subject to archival and review by someone other than the recipient.
