Oracle Database Discussions

Hi,

While stopping an Oracle database I have used "SHUTDOWN" command, to stop the Oracle database normally. But there are already some existing connections to the database. After shutdown normal Oracle waits for these connections to be disconnected themself.

Suppose these connections do not gets disconnected themself. Then Oracle won't allow you to connect to database again to kill those database sessions, and we are stuck. Though this can be managed by rebooting the database machine. But inspite of rebooting the machine, is there any other way as well to handle this scenario?

Thanks in advance.
