Excellent script! Was asked to restore a DB from some backupset files – no controlfile backups, no documentation. I had to create a dummy database and set dbid just to catalog the backupsets – so your script came in very handy.

Thanks a ton!

As far as I can see, the above approach is the only way to set the new DBID to a value you want. This is not possible with “nid” (a new value might be generated, but not *your* value)

Marcin, I can hardly more agree with you: use nid!

Hi GrÃ©gory,

Good stuff, but why not use just nid ?
Did you have any problem with that ?
I had been using dbms_backup_recovery from time to time when I had problems with RMAN and due to lack of catalog command in 8i and 9i.

Surachart,
why to change ID of database ? it is always a good when you manually duplicate your database into other one. why ? There is some problem without that with RMAN – see my blog entry – http://oracleprof.blogspot.com/ – about that

Good Article! Anyway I have no idea why? I should to change DBID.
Perhaps that make easy to remember or support.

My idea.. I don’t interest yet…

If it can help when I mess up all my backups. I think that’s very good.
