SELECT 'kill -9 ' || p.spid, s.username, 'alter system kill session ''' || SID || ',' || s.serial# ''' ' FROM gv$session s, gv$process p WHERE s.paddr = p.addr(+) and s.TYPE ='USER' and s.program like 'rman%' You can kill RMAN sessions which gives extra efor to the database like below. SELECT 'kill -9 ' || p.spid, s.username, 'alter system kill session ''' || SID || ',' || s.serial# ''' ' FROM gv$session s, gv$process p where s.SQL_ID like '4p5w3j8b3yhcw' and s.PADDR = p.ADDR (+) and s.STATUS='ACTIVE' order by 1 Sometimes you have just SQL_ID and you need to find sessions related with this SQL_ID, then you can find like below and you can generate kill script like below. SELECT 'kill -9 ' || p.spid, s.username, 'alter system kill session ''' || SID || ',' || s.serial# || ''' ' FROM v$session s, v$process p WHERE s.paddr = p.addr(+) AND s.SID IN (SELECT SID FROM v$session_wait WHERE event LIKE 'SQL*Net message from client%') and s.username ='DEVECI' and s.saddr not in ( select SES_ADDR from v$transaction ) You can change event to kill any other event group sessions. You can generate kill session script like below. alter system kill session '63,1963' Ĭustomer offers you to kill sessions group like SQL Net Client, or JDBC Client sessions or RMAN sessions. You can kill any session with its SID and SERIAL# number like below. select s.SID,s.SERIAL#,S.USERNAME from v$session s where s.sid=63 You need to find session SID and SERIAL# with below script. Sometimes application developers or client offers you to kill any session or sessions group like SQL Net Client, or JDBC Client sessions or RMAN sessions.
alter system kill session alter system kill session alter system kill session Kill Locked Session Query result will be like below if you have blocking session in your database. SELECT 'alter system kill session ''' || SID || ',' || s.serial# || (sql_id, 0), sql_address,blocking_session,wait_class,event,p1,p2,p3,seconds_in_wait FROM gv$session s WHERE blocking_session_status = 'VALID' OR sid IN (SELECT blocking_session FROM gv$session WHERE blocking_session_status = 'VALID') Alter system kill session You can generate Kill script of Blocking sessions like below. select s1.username || || s1.machine || ' ( THIS SID=' || s1.sid || ' ) is blocking ' || s2.username || || s2.machine || ' ( SID=' || s2.sid || ' ) ' AS blocking_status from gv$lock l1, gv$session s1, gv$lock l2, gv$session s2 where s1.sid=l1.sid and s2.sid=l2.sid and l1.BLOCK=1 and l2.request > 0 and l1.id1 = l2.id1 and l2.id2 = l2.id2 You can find momentarily blocking session and lock with below scripts. select v.sql_text,v.sql_fulltext,sub.* from v$sql v, (select sample_time,s.sql_id sql_id, session_state, blocking_session, owner||'.'||object_name||':'||nvl(subobject_name,'-') obj_name,s.program,s.module,s.machine from dba_hist_active_sess_history s, dba_objects o where sample_time between to_date(' 07:30:02','DD/MM/YYYY HH24:MI:SS') and to_date(' 15:10:02','DD/MM/YYYY HH24:MI:SS') and event = 'enq: TX - row lock contention' and o.data_object_id = s.current_obj# order by 1 desc) sub where sub.sql_id=v.sql_id
Change date time column which is specified with bold character. You can find historical blocking session and lock with below scripts.
