One needs to know the meaning of the kernel functions and their working within the oracle database. I guess, oracle support can do the analysis more easily as they have access to the software code as well necessary tools to interpret these internal routines.

pls guide with best practiceIn 11g, there is an extensive tracing that happens for the reasons best known to Oracle only. But if you want to disable it, Coskan had published a small post mentioning an undocumented parameter(which means you must think twice before using it) to disable it- disablehealth_check* .

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.

How to access Trace file in storage account

Hi,
I am new to Azure Cloud, I would like to know how to access the trace file stored in Storage account.
We have implemented diagnostics & traces, I have no idea how to access the trace file.
I have no idea what are the folders created inside the storage account and where the trace files are stored.
Would some one help me?
Thank you!

Hi,
In addition, you could use Azure Storage Explorer (https://azurestorageexplorer.codeplex.com/) to search your trace files.

How to find trace file error in form

i have one button ,when ever i press the button this error is ocuured,i check this button pl/sql procedure code but in this code not using that sql statement,
if any one know to find the sql statement through trace file.
plz give the replay as soon as possible.
thank's

The newest SQL Developer can converts the trace to readable format too, I'm not shure if you see the sql statement related to the error then.
It seems you get ORA-00904 which says you use an invalid coumn in a dml statement.
Normally such error should pop up in message - do you overwrite the message handling or use exception handling in you form which block this message?
Easiest way to find this is to compile the form against the target database.
If this does not give an error, you should check, if you use dynamic sql statements which are wrong.
If you call database routines from your form, than this could be the errro cause too.

How to change trace file location in Oracle Fusion Middleware

Hi all,
I would like to know how to change the location of the trace file in Oracle Fusion Middleware - Report Server 11g ?
I notice there is logging.xml file in $ORACLE_HOME/config/ReportServerComponenent/logging.xml. In the xml file, it did specify the location of the diagnostic file and other log files.
Is it the correct way to reconfigure the location of the log file? I havent try it though. :D
Thanks.

Hi Fleix,
For additional instructions for Release 11i, see Note.167635.1 and Note.150168.1.
For additional instructions for Release 11.0.3 and 10.7, see Note.148982.1 and Note.135715.1.
a. Append the following to the end of the URL used to login to the Oracle Applications:
?play=&record=collect&log=/tmp/oracle.FRD.log
** Note: The self service login URL will not work for creating FRD trace files. You may need to talk to your technical team to get the URL that accesses the forms server directly.
b. If the URL to logon to 11i applications is:
http://machine:9603/dev60cgi/f60cgi
Then the following label needs to be included:
?play=&record=collect&log=/tmp/'file_name'.frd
For example to create frd for above url log in to application as
http://machine:9603/dev60cgi/f60cgi?play=&record=collect&log=/tmp/4764802.992.frd
c. Now log into the application and go directly to the form with the problem and perform the actions which generate the error.
Once the error has been generated and cleared, immediately log out of the application so no additional diagnostics are captured.
d. The diagnostics will be written to the file specifed after "log=". In the example, this would be /tmp/4764802.992.frd
e. After reproducing the issue, log on the server side of the instance and go to the directory to /tmp (cd tmp)
f. Retrieve the frd file: /tmp/4764802.992.frd
This file contains all the details about built-in programs, triggers, procedures in a FORM
Thanks,
Anchorage :)

Listener trace should be humanly readable by itself and
oracle trace files should be processed by using tkprof.

How to read trace files alerted in the alert.log file

Hello,
My alert.log file indicated multiple trace files to review. How to read these trace files to understand the cause of errors. Do I open the trace files with vi and do a search for 'ORA-' error. Are there tools to read and understand trace files. Thank you.

It depends what kind of trace file it is.
You can use vi or other text editing tool to open the trace file. The trace file usually provides more detailed information when you have ORA- errors in alert.log. It's also very helpful for Oracle support when troubleshooting.

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.

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 .
Cheers,
Harry

Current SQL statement for this session:
SELECT NEXT_ID, UPDATE_DT_TIME, UPDATE_USER_ID FROM ID_V WHERE UPPER(TABLE_NAME) = UPPER(:B1 ) FOR UPDATE OF NEXT_ID
Has most of the information.
You have to check what session 126 and 147 were doing. It also gives you information on object_id and rowid where you had the lock by two sessions.
The culprit is FOR UPDATE OF NEXT_ID.

APEX Overhead and trace files

Hey everyone,
We've been asked to "stress" and "load" test our application as it is predicted our user base might grow in the near future (company acquisitions/etc)...
Unfortunately, there is concern about the overhead added by APEX. From everything I've read, I do not personally believe APEX adds much to each page view (as compared to our own self-managed data), however I need to PROVE this to our system admins/etc. Simply referencing things on the internet like "APEX doesn't add much overhead" doesn't exactly make the case.
To accomplish my mission, I've done the following:
1) generated a trace file on a test page by appending the following to the end of the URL:
"&p_trace=YES" (without quotes)
2) found the location of trace files using:
select value from v$parameter where name = 'user_dump_dest';
3) found the exact trace file for my apex page view
grep -l "3853406964369" *.trc (where the number in quotes was the session id taken from my apex url)
4) formatted the trace file using tkprof from the linux command line:
tkprof orcl_ora_24115.trc tkprof_output
Now, I'm in the process of examining the file. It is great that it shows everything involved in generating a page! A couple of quick questions though.
A) is it safe to assume that this trace file (found by using my method above in steps 1-4) only contains records associated with my single apex page view? My fear is that just because a file contains my session id, that does not guarantee that other random stuff from other sessions is also in the same file (sorry i'm new to trace files and especially trace files generated by apex).
B) if i view a second page with the trace=YES, will a second file get generated or does it get combined into 1 file? how can i easily tell which file is for which page view?
C) is there an easy way to differentiate what queries would normally be made by oracle (regardless of the UI) versus queries ran by APEX specifically (which would not occur if we were using PHP for a front end)?
Specifically, I see queries (similar to the following) that do not appear to be APEX specific from what I can tell:
-- example 1 --
select i.obj#,i.ts#,i.file#,i.block#,i.intcols,i.type#,i.flags,i.property,
i.pctfree$,i.initrans,i.maxtrans,i.blevel,i.leafcnt,i.distkey,i.lblkkey,
i.dblkkey,i.clufac,i.cols,i.analyzetime,i.samplesize,i.dataobj#,
nvl(i.degree,1),nvl(i.instances,1),i.rowcnt,mod(i.pctthres$,256),
i.indmethod#,i.trunccnt,nvl(c.unicols,0),nvl(c.deferrable#+c.valid#,0),
nvl(i.spare1,i.intcols),i.spare4,i.spare2,i.spare6,decode(i.pctthres$,null,
null,mod(trunc(i.pctthres$/256),256)),ist.cachedblk,ist.cachehit,
ist.logicalread
from
ind$ i, ind_stats$ ist, (select enabled, min(cols) unicols,
min(to_number(bitand(defer,1))) deferrable#,min(to_number(bitand(defer,4)))
valid# from cdef$ where obj#=:1 and enabled > 1 group by enabled) c where
i.obj#=c.enabled(+) and i.obj# = ist.obj#(+) and i.bo#=:1 order by i.obj#
-- example 2 --
select intcol#, toid, version#, intcols, intcol#s, flags, synobj#
from
subcoltype$ where obj#=:1 order by intcol# asc
and I see queries that are definitely APEX related (based on the existence of references to wwv objects):
-- example 3 --
SELECT ID, BRANCH_NAME, BRANCH_ACTION, BRANCH_POINT, BRANCH_TYPE,
BRANCH_CONDITION, BRANCH_CONDITION_TEXT, BRANCH_CONDITION_TYPE,
BRANCH_WHEN_BUTTON_ID, NVL(SAVE_STATE_BEFORE_BRANCH_YN,'N'),
SECURITY_SCHEME
FROM
WWV_FLOW_STEP_BRANCHES WHERE FLOW_ID = :B4 AND FLOW_STEP_ID = :B3 AND
BRANCH_POINT = 'BEFORE_HEADER' AND (REQUIRED_PATCH IS NULL OR
(REQUIRED_PATCH > 0 AND (:B2 IS NULL OR INSTR(:B2 ,
':'||TO_CHAR(REQUIRED_PATCH)||':') = 0) ) OR (REQUIRED_PATCH < 0 AND (:B1
IS NULL OR INSTR(:B1 ,':'||TO_CHAR(0-REQUIRED_PATCH)||':') = 0) ) ) ORDER
BY BRANCH_SEQUENCE, ID
and then of course it's easy for me to identify any queries that are based on our code because I recognize the object names we use.
In the mean-time I'm starting to look into how to interpret trace files (outside of the context of apex).
My biggest concern is that I do not want to "ding" or "tax" APEX for queries that it had nothing to do with and that would be ran by oracle regardless of the UI we use to "view a page".
Thanks!

Move older audit files to a different filesystem until you find someone being able to define what files can be deleted.
