Hi All,
I wrote one query .It's taking long time.To improve the performance of the query I got Execution plan and statistics of the table. Now I want to find out the trace file. Can any one please give idea to the way to create a trace file.long back I have created but I forgot that. I am not a DBA. So please guide me to create a Trace file (.trc). I have done in the following way. But I didn't get.
Alter session = 'True'
alter 10046 level 12;
<query>
alter sesion='false'
but I didn't get .trc file in my Inbox
Thank you,
|

Not only is the find command broken for him, he still hasn't told us what he really did, since what he posted doesn't work :
SQL> alter session set tracefile_identifier='TEST';
Session altered.
SQL> alter session set sql_trace='TRUE';
alter session set sql_trace='TRUE'
*
ERROR at line 1:
ORA-00922: missing or invalid option
