Hola, Why are you doing these as EXECUTE IMMEDIATE? Try alter session set TIMED_STATISTICS=TRUE; which should work as long as your session has alter session privilege (if not, connect as sysdba and grant it :) After you do the 10046 command, do some work (run a query or something) and then exit the SQL*Plus session and look for your tracefile. I like to use alter session set TRACEFILE_IDENTIFIER='myname'; Which will make identification of the tracefile easier since it places myname (or whatever you put there) in the tracefile name.

For example is there a way to fill them without using statpacks I tried EXECUTE IMMEDIATE 'alter session set TIMED_STATISTICS=TRUE'; EXECUTE IMMEDIATE 'alter session set STATISTICS_LEVEL=ALL'; EXECUTE IMMEDIATE 'alter session set max_dump_file_size=UNLIMITED'; EXECUTE IMMEDIATE 'ALTER SESSION SET EVENTS ''10046 TRACE NAME CONTEXT FOREVER, LEVEL 12'''; and didn't worked Thank you :) p.d. there is a free oracle database day dba. http://download-west.oracle.com/docs/cd/B12037_01/server.101/b10742.pdf ---------------------------------------------------------------- Please see the official ORACLE-L FAQ: http://www.orafaq.com ---------------------------------------------------------------- To unsubscribe send email to: oracle-l-request@xxxxxxxxxxxxx put 'unsubscribe' in the subject line. -- Archives are at //www.freelists.org/archives/oracle-l/ FAQ is at //www.freelists.org/help/fom-serve/cache/1.html ----------------------------------------------------------------- ---------------------------------------------------------------- Please see the official ORACLE-L FAQ: http://www.orafaq.com ---------------------------------------------------------------- To unsubscribe send email to: oracle-l-request@xxxxxxxxxxxxx put 'unsubscribe' in the subject line. -- Archives are at //www.freelists.org/archives/oracle-l/ FAQ is at //www.freelists.org/help/fom-serve/cache/1.html -----------------------------------------------------------------
