Hi guys,

              I was wondering what advice you had on limiting and organizing DBs into different RMAN schemas.
            We've got a client with lots of DBs, who wants to move more to RMAN.

Unfortunately not everyone is proficient in RMAN to start with (I got elevated to #2 in proficiency, but don't be excited about that) And we've had several cases where a DB was cloned and the DBID wasn't changed. So I got to fix the Incarnations.

    We've also had problems where a DB was upgraded to 10G but the schema wasn't etc., etc.

    We've got 3 different RMAN catalog databases. All     Some have schemas with as many as 30 DBs being maintained.     The DBs range from 8.1.6 to

    We've had a number of performance issues and earlier someone had split all the SAP DBs into their own. There's at least a dozen of those. The other schemas are generally divided into specific releases and prod/dev/test.

    I've been thinking about not using catalogs for the dev & test DBs and just sticking with the control files.

    We want to create another RMAN DB and I thought we might as well go to 11G, but everyone is very leery about that. I did like the new import feature in 11G.

    Suggestions and warnings welcome.
  Do have a copy of Note: 247611.1 Known RMAN Performance Problems

    TIA     Larry Wolfson
