ORACLE KILL SESSION WINDOWS
On Windows systems use orakill %ORACLE_SID% command (run cmd.exe with administrative privileges).You are in situation to quickly kill multiple sessions which consume high resource on database which cause performance issues. We can now go ahead and kill the process with “kill -9 ”. This means we safely kill the session’s OS process.įirst we have to figure out which process is the correct OS process of this session: SELECT s.sid, s.serial#, s.username, s.osuser, p.spid, s.machineĬolumn spid of this query shows the id of the dedicated server. In the above example the session is idle and not rolling back. If the session is busy rolling back, you should wait until it is done. To see if the session is rolling back you can use the awesome sql script from Tanel Poder ( ) : SQL> STATE EVENT SEQ# SEC_IN_WAIT P1Ģ63 WAITING inactive session 140 1584 152 If the transaction is huge this can even take hours. Normally transactions should be kept small but this is not the standard in production environments. When the session realizes the kill flag, it starts rolling back the open transaction. The session never checks for the flag which is an abnormal behavior (ignoring the flag).The session realizes the flag and starts undoing the changes (not really ignoring the flag).There are two reasons why a session would “ignore” the flag: The command sets a flag in the session which will make the session “commit suicide”. That is pretty ease but not always successful.Īn alter system kill session ‘,’ may not kill the session because that’s not what the commands does. There are many reasons why a dba has to kill a session.
