I hate second-guessing myself, but this is what I've been trying to tell him.

Here's another direct quote on my admonition for not running the database with archive logging:

"Thanks again for your help on this. we've [sic] not decided to run oracle in archive mode yet as content on this oracle [sic] instance will only be changed through replication and instead of recovering from archive logs it is easy to recover it from replication."

The replication to which he is referring is through the application (Documentum).

I considered offering him that option, but that wouldn't solve his problem. The background (briefly) is that this server, until Wednesday, was being "administered" by an engineer -- it's part of someone's empire here at Lucent, and [WAS] outside of the scope of my Unix system administration team. On Wednesday, one of the hard drives failed, taking with it many of the datafiles Oracle finds useful. Not surprisingly, it quickly became in-scope. We replaced the failed drive, then discovered that the system wasn't even being backed-up. Now, this developer wants a way to recover without, again, having to manually recreate the database.

Thanks again for the reply and the assistance!!
