Generating trace file in udump

Hi,
Database is 10.1.0.5 on windows 2003. There is trace file getting generated in udump which says:
opitsk: network error occurred while two-task session server trying to send break; error code = 12152
Thanks

I'm getting the same since patching from 10.1.0.5 patch 2 to patch25 when connecting over PL/SQL Developer and quering with large resultsets:
PL/SQL Dev query session lost on large resultsets after db update
Did you solve your problem ?

Generate Trace file when doing RMAN

OS AIX 5.3L with Oracle 10g (10.2.0.1), Since beginning of the RMAN backup, the Oracle generated trc file in udump and it is quite big ( over my dump_file_size limit). According to Metalink, it is a bug (Bug:4529700), since 2005 and it seems happening to all platforms. So does this bug have patch yet? How can I aovid the dump trace file to avoid exploring the storage directory?

*** DUMP FILE SIZE IS LIMITED TO 5242880 BYTES ***
because of the limit of my dump_file_size, so it stopped and Oracle generates another small one.
and these trace file always were generated at the end of the RMAN backup.
If you read the bottom of the note, it mention the bug: 4529700 -- Trace File Created During Rman Database Backup and in that note: it gave an example content of the file. You probably refereed to another bug: 4596065, which generated an empty trace.

No trace files in udump and bdump.

Dear all,
I have oracle 10g on linux.
There are no files in folder bdump and udump.What could be the reason.
Is there any parameter that need to be set.
Please advice.
Regards,
Amit.

Hello Amit,
Looks pretty strange you have all parameters set properly and you have physical directories available but you are not seeing any trace files.
Try this little test and see if oracle generates trace files.. or not.

Oracle generate trace file when log switch

Hi,
i am using oracle 9.2.3 on solaris 9. I found oracle generate a trace file in UDUMP directory when log file switch.
could anyone tell me how to tell oracle not to generate the trace file when log switch?
thanks a log

During switch are seeing any error in alert log? By the way what is the content of that trace file? Is any event set in your init.ora?
Thanks and Regards,

Generate trace file with required name

hi all,
as a sys user i want to trace a user session. so i am using
SQL> EXEC DBMS_SYSTEM.set_sql_trace_in_session(sid=>123, serial#=>1234, sql_trace=>TRUE);
SQL> EXEC DBMS_SYSTEM.set_sql_trace_in_session(sid=>123, serial#=>1234, sql_trace=>FALSE);
to trace. but this trace file is mixing with another trace files in udump.
did some google and found that we can use ALTER SESSION SET TRACEFILE_IDENTIFIER = "MY_TEST_SESSION". but this will generate trace file for sys user account not for the desired user session. how we can define trace file name for desired user session trace.
Please let me...
thanks

>but this trace file is mixing with another trace files in udump.
above is NOT true for any *NIX Operating System.
The trace file name will contain the OS ProcessID#
is this application 3-tier/
does application utilize connection pooling?

How can reduce generate trace file.

Hi all,
how can reduce generate trace file.
frequently created sql trace file in oracle 10g
approximate 5g in one day.
and database size 10gb
os windows

If you cannot disable the tracing for some reason, consider setting maximum file size for the dump.

How to Generate Trace Files in SQL*Plus

Hi Friends ,
How to Generate Trace Files in SQL*Plus ?
i have no idea
thanks
raj

What trace files would you like to generate?
Are we talking SQL trace files?
ALTER SESSION SET sql_trace = TRUE;This will be generated in the user_dump_dest on the server.
show parameter dump

How to generate trace file from different session?

I have a cron job which starts several Oracle stored proc (Oracle 9.2). I want to generate a trace file when the job is running. I know I can use this alter session command before I start this job. But this is my session not the job session. So this command won't generate trace file for job's session.
ALTER SESSION SET EVENTS '10046 TRACE NAME CONTEXT FOREVER, LEVEL 8';
Appreciate any ideas.
Thanks.
S.

Easiest way is to use database control/grid control - click trace session button!
The 'old fashioned way is'
begin
DBMS_SYSTEM.SET_SQL_TRACE_IN_SESSION(SID,serial#,TRUE);
end;
find sid and serial# in a select from v$session
There are other ways too but this is probably the easiest.
You'll need appropriate privileges to run this .

Harry

How to generate Trace files

Hi,
I have a package under which there are some procedures and functions.
I am supposed to generate the trace files for each run of the procedures in the package.
How to generate trace files? Pls help me out.
Thanks in advance
Regards,
Vijay

I dont have access to production server to see the
trace file. Is there a way to see the content of the
trace file from client machine?No. At least there isn't one without additional work from your administrator. I remember I've seen somewhere some kind of solution when user_dump_dest is used as oracle directory (specific oracle object) in your db and then use either external tables or utl_file or something like that to read the trace file. Of course this assumes your DBA should do some work before.
However I'd say that simply getting trace file from server is much easier :)
Consider, Autotrace option in sqlplus. With the help
of Autotrace set option, we can see the trace output
on the sqlplus screen for the anonymous blocks. Different tool, different behaviour.
Is there a way to see the trace for the stored
procedures?Explained above.

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.

Generating Trace file for ODI Sessions

ODI Gurus
am new to ODI, for one of our integration project am using ODI for transforming data from Source to Target Instance.
Oracle Database is installed on both Source and Target instances. Is there a way to generate Database Trace files for ODI sessions triggered.
If yes can you provide the steps to enable/disable database trace for ODI sessions.
Regards
Uma Shankar

Hi Uma Shankar,
My assumptions:
1.) You want to selectively enable Oracle tracing when only the ODI scenarios are executed and not otherwise.
If that is the case then you will have to add some external steps comprising of OS commands and variables that will control if those steps are to be executed or not. These steps will invoke the OS commands to start Oracle tracing.
2.) You know the steps to create a package and know how to use Interfaces and other ODI utilities in the flow of the package.
3.) You know how to create and execute scenarios
Steps to Selectively enable tracing.
1.) Add a variable named V_START_TRACE to the package. This variable will be passed a value from scenario which will determine if you want to enable to trace or not. This variable type is EVALUATE and can have 2 values - TRUE or FALSE. You will have to check for the condition and depending on the condition you will take a path forward.
2.) Add 2 OS commands to the package - OS_START_TRACE and OS_END_TRACE
3.) Create 2 shell scripts (or bat files) - odi_start_trace.sh and odi_end_trace.sh with the following commands:
odi_start_trace.sh :-
sqlplus session - ALTER SYSTEM SET trace_enabled = TRUE;
odi_end_trace.sh :-
sqlplus session - ALTER SYSTEM SET trace_enabled = FALSE;
You need to invoke SQLPLUS sessions from the above shell scripts to enable/disable the oracle level tracing.
4.) Add the above shell scripts to the OS commands created in Step 2.
5.) Join the steps in the following order in the package :
V_START_TRACE (OK) ->OS_START_TRACE (OK) -> <<+Your Actual Integration Code+>>(OK) -> OS_END_TRACE
V_START_TRACE (KO) -> <<+Your Actual Integration Code+>>(OK)
The above KO variable statement doesnt start the trace if the evaluated value doesnt = TRUE. So this will let you do a selective trace.
6.) Create the scenario from the package and execute the scenario by passing it a value "TRUE" for variable V_START_TRACE.
Check the startscen.sh syntax, something like:
*>startscen.sh ... "GLOBAL.V_START_TRACE=TRUE"*
The above is a general solution for enabling trace for any RDBMS
If you need any more information, feel free to ping back.

Why backup controlfile to trace doesn't produce the trace file in udump?

Hi there,
I recently redirected some of the data files on different drives. I started nomount with pfile and created new controlfile with the new datafile locations. I was able to open db and saw the new location of the db files. But when I trace the controlfile, I didn't see the trace file on the udump. Could anybody explain why?

also, when I did the show parameter I got the following results:
SQL> show parameter spfile
NAME TYPE VALUE
spfile string
SQL> show parameter pfile
NAME TYPE VALUE
spfile string
I did startup the db with pfile and open it with resetlogs. I created spfile from pfile. Why I'm not seeing the location of the pfile or spfile? Could you please help me understand this?

Generate trace file for a certain transaction

Experts,
I am trying to generate a trace file for a certain transaction for a period of time.
I used tx st03 > transaction profile > double click on transaction and am able to get a list for the day. How do I set the date to generate for the month for example?
Thanks,
Iqbal

Since you post the question in security forum, not peformance or platform forum, I guess are looking for system auditing function.
then SM19/SM20 might be the choice, you can read through

Generate trace file for a certain transaction by dates

Experts,

I used tx st03 > transaction profile > double click on transaction and am able to get a list for the day. How do I set the date to generate for the month for example?
Thanks,

Hi Iqbal,
In Tr. ST03 itself, you have three ranges. Day, Week and Month.
Just select the month. Expand it. Select which month you want.
Then check Transaction Profile. It should give you the details for the whole month.

How to SQL trace File in udump Folder

Hi,
I kept the Sql Trace for one database. Now i am getting the bulk of files in udump folder. I tryed the command
ALTER SESSION SET SQL_TRACE=FALSE
to stop the trace, but it is not stoping.
Now my problem is how to stop this file load in to that folder.
Thank u,

hi,
Thank u alok, Thank u very much. its working fine.
U told first that it is my mistake of enabling in database level. What are the real commands to start the trace and stop the trace by that session. What the Oracle Books says is this commands i followed ( Book name --- ORACLE HIGH PERFORMANCE TUNING FOR 9i AND 10g BY GAVIN POWELL ) Page -- 339
ALTER SESSION SET TIMED_STATISTICS = TRUE;
ALTER SESSION SET TIMED_OS_STATISTICS = 5;
ALTER SESSION SET MAX_DUMP_FILE_SIZE=1M;
ALTER SESSION SET SQL_TRACE = TRUE;
ALTER SESSION SET STATISTICS = ALL;
This command i followed. This is for session only, then why this is happened in database level.
Can u provide me the commands for start and stop the SQL TRACE.
Thank u for ur reply.
