I have setup Oracle7.3 on SCO Openserver 5.0.
While starting Oracle I was getting error “ORA:01110 File 30 needs media recovery.
I resolved this by following way:
1. Logged in as oracle user.
2. Gave below commands:
# svrmgrl
SVRMGR>connect internal
SVRMGR>startup
THen it gave same error. So DB got mounted but not opened.
SVRMGR>RECOVER
Media Recovery Done.
THen I restarted Oracle and it worked. This time it didnt show the error.
This means it recovered data from “redo.log”. I was lucky.
Cheers
