Re: Master Catalog query
This is giving me flash-backs In the 'bad old days' we used to manipulate the master catalog initialization code in NIP to actually do what you are talking about. We had one master catalog for 'production' jobs and one for 'test' jobs. We zapped the Operating System code at crucial points (Open, Close, etc), looked at the category of the job to determine which catalog to use, and then [pointed to the appropriate master catalog. The confusion this brought on cannot be overstated! Folks would catalog a SYS1 dataset with a 'test' job and wonder why it couldn't be found by a 'production' job. Also, it lead to datasets with duplicate names that had different data. It was a real mess and took a long time to clean up. End of story. Now, to your question...No, there is only one master catalog on a system. I am not sure what you are hoping to accomplish, but be glad that there is only one master catalog.

Re: Master Catalog query
Remember, this was back in the very early 1980's when IBM still distributed source code. It was written before my time, but I had to support it. That's when I learned about how to debug Standalone dumps and how to follow control block chains. I was VERY glad when we finally got rid of it (but on the other hand, it was a great learning experience). -Original Message- From: IBM Mainframe Discussion List [mailto:IBM-MAIN@bama.ua.edu] On Behalf Of Elardus Engelbrecht Sent: Friday, January 13, 2012 7:56 AM To: IBM-MAIN@bama.ua.edu Subject: Re: Master Catalog query Veilleux, Jon L wrote: In the 'bad old days' we used to manipulate the master catalog initialization code in NIP to actually do what you are talking about.

Re: Master Catalog query
The answer is still no... But if you have 2 images, you can have 1 mastercat per image and use them to be alternates of each other.

Re: Master Catalog query
At one of the places I worked, we had several LPARS and each one of these had its own master cat. Each mast cat was then connected as a user cat to the other masters and vice versa. When we created alias', we had to define each alias in each master. Also, when doing catalog work, you had to remember to disconnect the user cat from all masters then, when finished, re-connect it to all the masters.

I tried searching google with keyword Multiple master catalog but I ended up with master-catalog sharing concept. Could anyone please share your thoughts or idea. Few thoughts: 1. user catalog structutre is the same as master catalog structure. The difference is in role being played at the moment, and the content. 2. You can have copy of any catalog (BCS), including all your user catalogs. 3. Any copy of any catalog (BCS) is like a cold (tape) copy, not live replica. What does it mean? Your catalogs are live, are being updated, your copies are not. So, after you restored the catalog you need to perform forward recovery. 4. Master catalog is crucial for the z/OS, but not for you. Yes, you need z/OS to make your application working, but if you loose user catalog containing you application data - you will have z/OS, but no application. Conclusion: you should care about both master and user catalogs as well. -- Radoslaw Skorupka Lodz, Poland -- Tre tej wiadomoci moe zawiera informacje prawnie chronione Banku przeznaczone wycznie do uytku subowego adresata.
