    ORA-01102: cannot mount database in EXCLUSIVE mode

      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
