I am working with an Oracle 8i database. I logged to the Oracle Enterprise Manager as sysdba and shut down the database in the normal mode. But it is taking a lot of time and the OEM session also got hung. Now I cannot log on to the database, it says that it is shutting down (ORA-01081). I tried to start it again but I get the same message.
I am not sure what users are still logged on to the database. There is an application which runs on the database and it may have open hung sessions in it.
