I have 2 instances on the server (8.1.6)
Till noon it was fine..
Now that I try to start up the 2nd instance, I set the ORACLE_SID and HOME and PATH to respective paths and when I start the db it says:
ORA-01102: cannot mount database in EXCLUSIVE mode
Why is this. The other DB is simply fine.. When I log into the unix as oracle user, the default profile is set to the other db and then when i need this 2nd instance I change and use..
But not anymore, I tried shutting down the 1st.. same problem.. Why?
Thx..
