ORA-01093
ALTER DATABASE CLOSE only permitted with no sessions connected
Cause
There is at lease one more session, other than the current one, logged in to the instance. ALTER DATABASE CLOSE is not permitted when other sessions are active.
Action
Find the other sessions and disconnect them. Then retry the ALTER DATABASE CLOSE command. Also, issue the SHUTDOWN IMMEDIATE command to force users off the system, or issue the SHUTDOWN ABORT command to shut down the database without waiting for users to be forced off.
