Hi Terry,

I've read all the other list reponses. Suggestion?
Look for partial exports to help rebuild portions of
the lost tablespace(s)? What a mess.

You could also suggest they immediately attempt to
prevent similar/further hardware failures at the site,
unless its proven to be a singular disk system
failure. You might help with risk analysis of their
other (undamaged) databases and files, or help get
some answers from their SA/DBA/etc (new or old).
Preventing further issues can save the day after a
single data loss.

They should be willing to listen based on (1) how much
they value their data, or (2) how much the IT
department value their jobs.

Good luck, I hope it works out for you.

Regards,

Mike Thomas

PS: Ask the IT director if he/she has read what's in
envelope three. Just kidding. ;-)
