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

Do a query:

SELECT * FROM v$session s;

Find your user and do the next query (with appropriate parameters):

ALTER SYSTEM KILL SESSION ', ';
