You can do either and will some associated issues. Here are some: If you have a MCAT for each LPAR you will have so many MCAT's + its backup to maintain and garbage in it piles up with time.
If you have a shared MCAT, you need to maintain one MCAT/SYSPLEX and one backup.At the time of z/OS upgrade create a new SYSPLEX MCAT (you may have one character in MCAT specific to z/OS versrion/release in MCAT name) ( gives you opportunity to cleanup / gives you opportunity to test z/OS upgrade in DR ahead of time). One will need to keep two MCAT SYNCed up during the upgrade.

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 The information contained in this e-mail, and any attachment, is confidential and is intended solely for the use of the intended recipient.
