ORA-01102 Cannot mount database in Exclusive mode

Hello,

I performed Shutdown Immediate in Oracle 8I and now I am unable to mount the database.
I’m getting the following message: “ORA-01102 Cannot mount database in Exclusive mode”
I only have one database running on this machine. It was automatically created by Oracle installer upon installation of Oracle software. I can no longer connect via SQL * Plus,
Only through Server Manager (connect internal) Please advice on how to fix this. I am new at this so detailed advise is highly appreciated.

Thank you for your help,

Kira

is it unix

if u r using WIN NT/2000

check the services in control panel.
if there is another service for Oracle ( u might have tried to create another database ) stop that service.

shutdown the database
startup

if still the same error. check the instance name in v$instance

You are probably not starting up the right DB. Check that you have the right init.ora in the startup command and that ORACLE_SID is correctly set. If NT, then run first SET ORACLE_SID=XYZ, if UNIX then: ORACLE_SID=XYZ export ORACLE_SID.

I am almost sure that you are trying to mount a DB which is already mounted by the other intstance.
