Harold, You say "usually IBM tends to rename the sys1 files, moves them to other volsers, changes sizes of files which tend to force file to different volsers. etc.". I may not understand what you mean by this, but I have not really encountered these issues.
Many of the data sets are on the sysres (or its extensions) and the catalog entries can use indirect volsers or symbols. If it's on the sysres for 1.4, it will probably be on the sysres for 1.7. So the 1.4 catalog entry with volser ****** will still work for 1.7; when you IPL a 1.4 sysres, those will point to that volume; when you IPL a 1.7 sysres, they will point to the 1.7 sysres. Other data sets tend to stay in place also, whether it be a volume for HFS/zFS data sets or operational data sets such as SYS1.PARMLIB; so catalog entries for 1.4 will still work for 1.7. With each new release, you can use ServerPac to identify what data sets are new and where they are located. You can add those entries to your master catalog without impacting the running of your 1.4 system, but still be ready to run 1.7. If IBM 'tends to rename the sys1 files' (which I don't really think they do), add the new name to the catalog. When you've completed conversion to 1.7, then delete the old unneeded entries.

I don't see how you can easily get away with not building a new master catalog. ----- Original Message ----- From: "Imbriale, Donald (Exchange)" <[EMAIL PROTECTED]> Newsgroups: bit.listserv.ibm-main To: <[email protected]> Sent: Friday, December 29, 2006 10:50 AM Subject: Re: Catalog Question <snip> Second, you can avoid this issue in the future by abandoning the process of building a new master catalog for each new release of the operating system. <snip> *********************************************************************** Bear Stearns is not responsible for any recommendation, solicitation, offer or agreement or any information about any transaction, customer account or account activity contained in this communication. *********************************************************************** ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html
