The 'ORA-01102' error means the instance is already mounted. You have to make sure the instance is shutdown before trying to mount it again.

If Windows - check your Oracle service, stop and start again

If Unix - kill the background processes, check the shared memory & semaphores (ipcs), and start the instance again.

Hope that helps,

I think you'd give us your OS and oracle version info before your asking.

Actually, you are not alone. More than one case give rise to such kind of error message. Some guy from this space got this problem in parallel db, solaris env, primary/standby db, etc. In addition, I ever ran into this problem when i was trying to startup my 2nd oracle 817 db on redhat 7.3 after my successful startup of the 1st 817 db. I agree to some people that the instance is confused about which database to start. so I just specify pfile in the startup command, FYI:

SQL>startup pfile=/app/oracle/admin/RCAT/pfile/initRCAT.ora

and it was cleared.
hope it helps!
