Oracle Database Discussions

Hi,

Oracle 11g
Windows/Unix

I have a program that kill all users before doing export dump.
This is the select statement that will spool to kill_user.sql

select 'alter system kill session '||''''||sid||','||serial#||''';' from v$session where type='USER';

This program is placed scheduled task for windows or crontab for unix.
My problem is, how can I exempt the owner(sched task) of the program from being killed?
You know that it will be included in the list at the time the select statement is run, right?
And I might happen that it is the first one to get killed, which results to not killing all rest of the users. Is my logic right?

Please help....

Thanks
