Clearing locks automation

Question

hi,
We have OEM 10.2.0.4 and we get blocking session's from Blocking Session Count metric. Here we manually clear locks. we wanted to automate it forms related locks only thru corrective action. Can you please share your thoughts?

Answer 1

You can do this by creating a corrective action script based on the blocking session alert. Set the number of occurrences on the alert to the length of time you want to wait before killing the session. I had this corrective action SQL script running in OMS 10.2.0.3. (Not sure about 10.2.0.4).
spool /tmp/killed_session.out
set feedback on
set heading on
set echo on
set serveroutput on
DECLARE
v_sid varchar2(15);
v_serial varchar2(15);
BEGIN
select substr('%key_value_sid%',instr('%key_value_sid%',':')+2,instr('%key_value_sid%',' Serial#')-6)
into v_sid from dual;
select substr('%key_value_sid%',instr('%key_value_sid%',':',1,2)+2)
into v_serial from dual;
dbms_output.put_line('killed session sid :'||v_sid||' serial :'||v_serial||' %key_value_sid%');
execute immediate 'alter system kill session'||chr(39)||v_sid||','||v_serial||chr(39);
end;
exit;
