Replies:
Oracle version is 9i Release 2. Same client.
OS is SOLARIS 9. I have the same on windows too.

DB gets started but after some times it gives this error and on
windows when u use TOAD, this is the most obvious error after some
time ( 3 -4 days..).

All rations are fine, no problem at all.

Anything else ???

Hope this is quite enough.
