10046跟踪事件

一、打开

alter session set events '10046 trace name context forever,level 12';

二、写SQL 内容

select
wmsys.wm_concat(mcc.CODE) as CODE
from test.T_test_TYPE mcc
LEFT JOIN
mss.T_test mcc1 on mcc1.TYPE=mcc.CODE
where mcc1.VALID='1' and mcc.VALID='1'

三、关闭10046事件

alter session set events '10046 trace name context off';

四、获取trc文件位置

select
d.value||'/'||lower(rtrim(i.instance, chr(0)))||'_ora_'||p.spid||'.trc' trace_file_name
from
( select p.spid
from sys.v$mystat m,sys.v$session s,sys.v$process p
where m.statistic# = 1 and s.sid = m.sid and p.addr = s.paddr) p,
( select t.instance from sys.v$thread  t,sys.v$parameter  v
where v.name = 'thread' and (v.value = 0 or t.thread# = to_number(v.value))) i,
( select value from sys.v$parameter where name = 'user_dump_dest') d
