Hi,

Thanks for immediate response

my observation :

1. I found from log/trace file that one of the data file stored in
another Hard disk, which is crashed. is there anyway to recover data as on date. all other datafile are safe in another hard disk.

2. why user internal is not connecting to server manager
error message : invalid username/password
if i use orapwd utility , can i able to connected to server ?

3. last option i hv some old back(user) can be useful.

Regards,

Ari.
