Oracle Database Discussions

Hi ,

To give a small background , today I was getting the following error while trying to connect to one of the schema.
I am seeing the same error on my EM console too.

ORA-01033: ORACLE initialization or shutdown in progress (DBD ERROR: OCISessionBegin)

To resolve this issues , I thought of doing a manual start up . The shutdown was successful and failed to mount the DB . I am getting this error "ORA-01102: cannot mount database in EXCLUSIVE mode"

SQL> shutdown abort;
ORACLE instance shut down.
SQL> startup;
ORACLE instance started.

ORA-01102: cannot mount database in EXCLUSIVE mode

Could someone help me in resolving this issue? I am using Oracle 11.2.0 on Window 7

Thanks,
