It is standard procedure here to record the DBID in our "database fact sheets" for each database. I think this is recommended as a "best practice" somewhere in the Oracle rman doc. Plus, we keep logs of our rman output so we could find the DBID (as well as the entire backup piece handle) there too as long as those logs aren't lost along with the database. I think there are a few other places the DBID can be found but I can't think of them off the top of my head.
