Dropping connected users in Oracle database
oracle
Solution
Users are all capitals in `v$session` (and data dictionary views). If you match with capitals you should find your session to kill.
SELECT s.sid, s.serial#, s.status, p.spid
FROM v$session s, v$process p
WHERE s.username = 'TEST' --<<<--
AND p.addr(+) = s.paddr
/
Pass actual SID and SERIAL# values for user TEST then drop user...:
ALTER SYSTEM KILL SESSION '<SID>, <SERIAL>'
/
Problem
I want to drop some users in Oracle DB using sqlplus but I am getting error: ``` SQL> DROP USER test CASCADE; DROP USER test CASCADE * ERROR at line 1: ORA-01940: cannot drop a user that is currently connected ``` I followed the link in SO to find out the sessions - Dropping a connected user from an Oracle 10g database schema But when I ran the command I am not getting any results: ``` SQL> select sid,serial# from v$session where username = 'test'; no rows selected ``` Please help me how to drop users in this case.
