573141Oct 9 2008 — edited Oct 14 2008hello all
I have been asked to look into a problem server with the following details
OS: sunOS 5.8
Oracle: 10.2.0.1
sys user password is not available !
backgrround processes for the instance(sid=test) are running
only schema credentials available and with that user is able to connect.
verified all oraenv parameters(ORACLE_SID is same as the running instance(test)).
only one instance is configured in this server(verified all tnsnames.ora, data files etc).oratab is empty
the issues are,
when I tried to connect to the server using "oracle" user using conn / as sysdba
1. Tried to shutdown using , shutdown immediate
ORA-01507:database not mounted
ORACLE instance shut down
still able to see the background processes and user is able to connect
2. Tried startup command,
In the nomount state I can see more than one PMON process with the same sid
when tried to mount/open
ran into the error,
ORA-01102: cannot mount database in EXCLUSIVE mode
Eventhough the background processes for the "test" instance are running I am not able to shutdown the instance using "oracle" user
please help
newbie
