Dropping connected users in Oracle database

Question

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-01         


        

Answer 1

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 ', '
/
