Let everyone know that it is going to happen, and when.
Provide an alternative catalog to use (optional).
At the "when", back it up to site standards.
Delete it.
Spend the first hour of the following Monday waiting for the 'phone to ring.
It goes without saying, but here it is, you also test everything first. You test the backup, by ensuring that you can restore it. Checking all output messages, check that same amount of space is used, following-up on anything you don't understand. You need a clean backup/restore before you consider the delete.
To test the delete, define a new catalog. Catalog some datasets to it. Back it up. Delete it. Restore it. Delete it.
On the other hand, why are you doing it? Don't you have some storage people whose job it is to do stuff like that? |

| Beware ........ any Vsam clusters that are owned by the user catalog will also be deleted. Check the contents of the User Catalog to be deleted. You will be suprised how many "obsolete" catalogs are still the owner of Vsam Clusters. |

| Probably your master catalog is pw protected, and there will be no one to tell you that pw. So since you only browse, let the people who know handle that. |

Hi I did the below:
1. Removed the Datasets and Alias related to the UCAT
2. Deleted the UCAT using IDCAMS DELETE.

| That sounds great, deleting a ucat without a master catalog pw. Now try to delete the master catalog, that will be funny if its not pw protected. |

Peter, maybe he knows the PW 
Just a case of going around and checking that there are no entries related to the catalog still exist in all of the VVDS on the system.
Usually a few laying about after a UCAT delete, and they crop up with errors from time to time too. |

Hoo-boy, do I remember that! I defined a TSO HLQ one time and forgot to put in the REL(usercat). They didn't have write access to the master catalog, so there wasn't much they could do on the system! It took a couple of looks to figure out what I'd done wrong. |

I recall biffing a UCAT and for some strange reason (read user error) where he'd left a STEPCAT in the job, and could I get rid of that particular dataset.
Well, Yes, of course I could, but it did take a while.
Robert, admitting to a mistake. Oh God, does this really mean that sysprogs are only human too |

| I told an application programmer one time the main difference between their job and mine was that when they made a msitake, it would be known by the on-call person and themselves whereas when I made a mistake, EVERYBODY knew about it! |

Don't forget to EXPORT DISCONNECT the Usercatalog from any other alternate Mastercatalogs
ps: Be VERY afraid of using the FORCE parameter when deleting a Usercatalog! Had a weekend competely ruined by that about 20 years ago. |
