I expect the angels probably sing when your shell scripts are running Rachel.

I wondered why a database was needed to store the information. It's obviously NOT needed or you couldn't use the controlfiles for the RMAN information. and for what it's worth, no matter how fancy I CAN write a script, I try to write it as "plain vanilla" as possible, with lots of comments about what I am doing at each step. I realize this sets me apart from the norm but who wants to be normal? --- Freeman Robert - IL <[EMAIL PROTECTED]> wrote: > I actually think RMAN is pretty simple.
