Huge user trace files being generated under udump

last few days one of my database is generating huge number of user trace files under udump. I tried to investigate in alert.log file. But as I am not very expert to analyze the alert.log file I could not find the cause behind it. Only the ORA-00600: internal error code is found there. But it is a generic error . Please help.

Thank you again. I got the clue from your reply.
The error message is pasted below in short.
ORA-00600: internal error code, arguments: [12333], [0], [0], [0], [], [], [], []
Current SQL statement for this session:
BEGIN :1 := TESTDBA.LOCAL_SYSDATE_SFT_FNC( 1,:2,:3 ); END;
And it is obvious that the function had some problem recently. We need to investigate on that. Now my request is
Please guide me how to check in metalink with the value '12333' which came as argument of ORA-00600 error. Here my job was easy as I got the problem function name . By I want to know the art of analysing the error message in alert.log file.
Also tell me which places I should check regularly as a responsibility of a DBA ?
What are the common errors in Alert log file? Where I should be cautioned ? Where I should ignore. Give me some tips please. Do not restrict your discussion on Alret.log only . Also please cover all important areas. If you think I am taking much of your time then please send me some link or source of PDF etc.

Where is the user trace file?

I have issued the statement below to enable sql trace in session 260 ,and it execute successfully.but i can not find where the trace file in directory $ORACLE_BASE/admin/testcs/udump (testcs is my database name).
SQL> execute dbms_system.set_sql_trace_in_session(260,34880,true);
PL/SQL procedure successfully completed.
where is the trace file?
By the way,how can i find the information about the package DBMS_SYSTEM which is not in ORACLE references?

Did you issue some queries after turning tracing on? The trace file might not be created until there is some activity in the session.
I know that DBMS_SYSTEM is documented in the O'Reilly Press book "Oracle Built-in Packages" by Feuerstein, Dye & Beresniewicz.
However for tracing I think that Oracle expects you to use the dbms_support package:
execute sys.dbms_support.start_trace_in_session -
(sid => &sid, serial => &serial, waits => true, binds => true)Or for Oracle 7.3.4 or 8.0 you can use oradebug. Example:
select pid, spid, username from v$process;
PID SPID USERNAME
8 25807 oracle
SVRMGR> oradebug setorapid 8
-- or -
SVRMGR> oradebug setospid 25807
-- turn on
SVRMGR> oradebug event 10046 trace name context forever, level 12
-- turn off
SVRMGR> oradebug event 10046 trace name context off

Question regarding alert log file and trace files

What should be the alert log file size ? And when should it be deleted? And for how many days user trace files should be kept?
Also will anyone please tell me the importance of these files.
Thanks

Create a new trace-file

hello together,
i have a question according to creation of new user trace files in user_dump_dest:
with the following command:
EXEC dbms_system.set_sql_trace_in_session(18,628,TRUE);
I created a new file in the trace directory.
Then I stopped the tracing with:
EXEC dbms_system.set_sql_trace_in_session(18,628,FALSE);
I disconnected with the traced session sid=18 and connected once again.
With retracing the session I didn't get a new trace file but the existing trace file was actualized.
=> what do I have to do to achive a new trace file for the second session-tracing?
Thanks and Regards
Stefan

Hello Maran,
I only want to trace one session; but I want to create a new trace file for the second run when tracing; but at the moment the first trace file will be continued...
thanks

Trace file and control files !!

hi,
I have created trace file of the control files by using 'alter database backup controlfile to trace' command. i have two questions..where can i find this trace file and how can i use this trace file to generate the control files.
Waiting for the replies...
Regards,
Saad Bin Khalid

1. You can fine the trace in the udump folder ... you can check the file time stamp to check when you created the file as it may be possible that here are other user trace files too
$ sqlplus / as sysdba
SQL> alter database backup controlfile to trace;
Database altered.
SQL> show parameter USER_DUMP_DEST
NAME TYPE VALUE
user_dump_dest string /PROD/udump
SQL> exit
$ cd /PROD/udump
$ mv PROD_ora_30823.trc cr_ctl.sql
$ vi cr_ctl.sql
edit the control file script
Now you have a new control file script to re-create your control file.
2. You can edit the same and execute at nomount stage to generate new controlfiles ... remember controlfiles should be removed before creating the new ones

How can stop the bdump and udump trace files from accumulating?

The files are growing so until it is filling up the user's c: drive. It's hundreds of files over 20 megs.

Angela,
The management of those files is a reposnsibilty of the DBA. ie The files dumped there are from background processes, session traces and your alert log.
The alert log in bdump should be checked daily and errors investigated. Some errors will result in trace files being dumped. The alert log will always grow during normal operation and you can simply delete it or better yet zip it up and store it somewhere for a period of time.
You can clean up the udump user traces files by simply deleting them periodically. For other traces you should have a look to see what they are for. Any ORA 600 traces should be investigated.
If you are not a DBA and this seems to much trouble then you can just delete the files to reclaim the space.

How to find username from trace file for deadlock due to user

This is the info from the trace file.
*** 2003-08-18 08:07:40.590
*** SESSION ID:(560.60728) 2003-08-18 08:07:40.560

The following deadlock is not an ORACLE error. It is a
deadlock due to user error in the design of an application

Tkprof : 0 user SQL statement in trace file

Hello!
Please explain , what is difference of tkprof-converting of user session trace file and an internal/background process ?
Get I message "0 user SQL statement in trace file" cause this difference?
In my target session I issued :
begin
sys.dbms_system.set_ev(...., .., 10046, 12, '');
end;
begin
sys.dbms_system.set_ev(..., .., 10053, 1, '');
end;
/Thanks and regards,
Pavel

Did you try to tkprof a 10053 trace ?
That is not going to show anything. 10053 traces are meant to be read as they are. tkprof is there to deal with 10046 traces.

How to stop the generation of the trace files relate to the particular user

Dear All,
Please advice:
Is it possible to stop the trace file created by a user for a particular job (sql/exp)
For example :
Trace files create whenever the user run the sql/exp command from his application server.
This will created a huge files and caused the file system getting full (not in bdump but it is generation in application user home directory).
Is there any method to stop the generation of the trace files relate to the particular user base on that job.
thanks,
Shanoj

Dear SHANOJ
This trigger will created for that specific user by dba or person who have sysdba privs. it will triggered at the login time of that user and alter the sqltrace.
for example we have write one trigger in our database for every ddl operation in database.
CREATE OR REPLACE TRIGGER "SYS"."SYS$DDLTRIG" after DDL on database
declare
v_machinename VARCHAR2(100);
v_osuser VARCHAR2(100);
v_dbuser VARCHAR2(100);
v_host VARCHAR2(100);
v_program VARCHAR2(100);
v_instance VARCHAR2(100);
v_date VARCHAR2(100);
begin
select to_char(sysdate, 'mm-dd-yyyy HH24:MI:SS'),user,sys_context('userenv','OS_
USER'),sys_context('userenv','HOST'), (select instance_name from v$instance),(se
lect program from v$session where sid = (select distinct sid from v$mystat)),(se
lect machine from v$session where sid = (select distinct sid from v$mystat)) int
o v_date,v_dbuser,v_osuser,v_host,v_instance,v_program,v_machinename from dual;
IF ora_sysevent = 'DROP' or ora_sysevent = 'REVOKE' or ora_sysevent = 'GRANT' or
ora_sysevent = 'CREATE' or ora_sysevent = 'TRUNCATE' or ora_sysevent = 'ALTER'
Then
insert into ddl_log_new(v_date,v_dbuser,v_osuser,v_host,v_instance,v_program,v_m
achinename,V_EVENT,V_OBJECT_NAME,V_OBJECT_TYPE,V_OBJECT_OWNER) values (v_date,v_
dbuser,v_osuser,v_host,v_instance,v_program,v_machinename,ora_sysevent,ora_dict_
obj_name,ora_dict_obj_type,ora_dict_obj_owner);
END IF;
END;
i hope above example will helpful for u,

Trace file event set....need the file for the user...

hello all,
i had a question about the trace file, I was asked by one of ur manager to set events for trace file...he asked to do this...
ALTER SESSION SET EVENTS '10046 trace name context forever, level 12';
alter system set events '1483 trace name errorstack, level 12' ;
i understand they go to the udump, but my question how am i suppose to know which trace file to look as there are tons of them in udump??? We actually want this for a specific schema that we are lookin for. Could anyone explain what the above are doing and how to get the trace file for it. Thanks

If you are running this from your session and want to check the file that has been created for your session,from Effective Orcle by design,this may be helpful,
select rtrim(c.value,'/') || '/' ||d.instance_name ||
'_ora_' || ltrim(to_char(a.spid)) || '.trc'
from V$process a,v$session b,v$parameter c,v$instance d
where a.add=b.paddr
and b.audsid=sys_context('userenv','sessionid')
and c.name='user_dump_dest'This would tell you the exact file that would had been created for your session.

Remove the line alter session set sql_trace=false and just exit/disconnect. The explain plain is contained in the STAT lines in the trace file and are only written when the cursor closes. If you turn off tracing before the cursor closes the STAT lines will not get written.

Unable to generate trace file

Hi,
I have written the stored procedure for starting sql trace on a given session for say n number of seconds.
create or replace procedure start_trace
v_sid in number,
v_serial# in number,
seconds in number)
IS
v_user varchar2 (32);
duration number;
dump_dest varchar2 (200);
db_name varchar2 (32);
no_session_found exception;
stmt varchar2(100);
stmt1 varchar2(100);
BEGIN
begin
select username into v_user
from v$session
where sid= v_sid and
serial# = v_serial#;
exception
when NO_DATA_FOUND then
raise no_session_found;
end;
dbms_output.put_line('Tracing Started for User: '|| v_user);
dbms_output.put_line('Tracing Start Time: '|| TO_CHAR(SYSDATE, 'MM-DD-YYYY HH24:MI:SS'));
dbms_system.set_sql_trace_in_session(v_sid,v_serial#,true);
if seconds is null then
duration := 60;
else
duration := seconds;
end if;
dbms_lock.sleep(duration);
dbms_system.set_sql_trace_in_session(v_sid,v_serial#,false);
dbms_output.put_line ('Tracing Stop Time: '|| TO_CHAR(SYSDATE, 'MM-DD-YYYY HH24:MI:SS'));
select value into dump_dest
from v$parameter
where name = 'user_dump_dest';
dbms_output.put_line('Trace Directory: ' || dump_dest);
exception
when no_session_found then
dbms_output.put_line('No session found for sid and serial# specified');
END start_trace;
The above procedure compiles successfully and when I call it from sql prompt it gives me the message that the pl/sql procedure was completed successfully and all put_line statements are displayed.
Real problem comes when I check udump for the trace file. I can not find it there. It seems all the statements in the procedure are executed successfully except dbms_system.set_sql_trace_in_session(v_sid,v_serial#,true) and dbms_system.set_sql_trace_in_session(v_sid,v_serial#,false) for some strange reasons.
Any help will be appreciated.
Thanks.

Thanks for the reply.
I do not get any error message. The following is the output:
SQL> exec start_trace(118,6243,30);
Tracing Started for User: SVCWRK
Tracing Start Time: 09-26-2011 16:28:29
Tracing Stop Time: 09-26-2011 16:28:59
Trace Directory: /orasoft/app/oracle/admin/testsvcb/udump
PL/SQL procedure successfully completed.
But the trace file is not generated.
I am using Oracle 10.2.0.4.0.
Will try using DBMS_MONITOR.
Thanks again.
