Hi Guillaume, We have been running the Oracle TDP for several years, and this has ALWAYS been a problem. The backup objects are described by metadata BOTH in the RMAN backup catalog and the TSM DB. Several things can cause the two DB's to get out of sync, and then you have backup pieces left in TSM that take up space.
We have used 3 different ways to deal with it: 1) If you are running a recent version of the TDP, there is the TDPOSYNC utility. This is new (in the 2.2 version, I think) and addresses the problem where the RMAN catalog and the TSM DB are out of sync. The description of the utility: "This utility checks for items on the TSM server that are not in the RMAN catalog and allows you to repair such discrepancies. By thus removing unwanted objects in TSM storage, you can reclaim space on the server." It is described in the TDP manual, search on TDPOSYNC. Try this first, as it is the supported method for cleaning up. 2) There is the unsupported DELETE OBJECT command: delete object 0 nnnnnn where nnnnnn is the object id of the backup you want deleted from the TSM DB. You can get the objectid from the BACKUPS table: select * from backups where node_name='WHATEVER' The DELETE OBJECT command is unsupported; but I have used it on more than one TSM server, and have never heard of anyone having a problem with it. (Have never used it on a 4.2 system, though.) 3) Rename the FILESPACE on the TSM end. The next time the TDP does a backup, a new clean filespace will be created, and future backups will go there. Keep the old filespace around for 10 days or 30 days, or however long you want to retain those backups. Then delete the old filespace. (Now if you want to do a restore from the old filespace, you will need to rename it back to its original name temporarily.) We have used all 3 methods successfully at different times.

This being the first time I used TDPO, I didn't use a nodename for each database, I used a nodename for each server. So now I have 3 or 4 databases using the same nodename. SOme of these databases have since disappeared and I am stuck with the backups. The Oracle admin can't seem to figure out how to get RMAN to delete the backups and since they are in the active state, they will never expire. I've opened a PMR on this and I'm hoping for a miracle. That Share request about being able to delete 1 file from backups and not only a filespace seems to me would be migty handy here. If anyone out there in TSM land has a recipe, please share.
