file=/oracle/DV2/sapdata3/btabi_15/btabi.data15. found valid data

This is not a problem - just RMAN complaining when it doesn't need to. Key thing is "found valid data" at the end. Happens only in 8i, should no longer appear in 9i.

However, you can also get the message in 9i with no corresponding "found valid data". Now - that is a real problem!
