SQL> shutdown abort
ORACLE instance shut down.
SQL> startup mount
ORACLE instance started.
ORA-01012: not logged on
Process ID: 0
Session ID: 0 Serial number: 0
It appears that the shutdown abort was successful but the mount command did not complete. Disconnect from the previously connected session and logon normally to start the instance.
SQL>exit

SQL>startup mount
Now we can go ahead and increase our processes parameter. Actually I opted not to increase the parameter since I knew the root cause of the processes being exceeded. This was a Enterprise Manager Grid Control repository and due to some OMS processes had caused the database processes to be exceeded.
