Session doesn't die with ALTER SYSTEM KILL SESSION
I'm trying to kill a session with ALTER SYSTEM KILL SESSION '<SID>,<Serial#>'; as the Administrator user.
When execute the ALTER SYSTEM KILL SESSION, I see:
System KILL altered.
But when I query V$SESSION, the session status is still ACTIVE.
I've also tried
ALTER SYSTEM DISCONNECT SESSION '<SID>,<Serial#>' IMMEDIATE; as the Administrator user, but when I do, I get:
Error starting at line : 24 in command -
ALTER SYSTEM DISCONNECT SESSION '48333,52001' IMMEDIATE
Error report -
ORA-01031: insufficient privileges
01031. 00000 - "insufficient privileges"
*Cause: An attempt was made to perform a database operation without
the necessary privileges.
