Help to interpret trace file
Hi,
Can someone please tell me what is the meaning of stack number in the file generated ny dbms_trace. how to interpret the trace file.
Thanks in advance.

Hi,
The cause of an ORA-1555 is quite simple :
U start a long transaction (named T1) at time t1. Ur transaction T1 made lots of things such as
insert/update/delete, ...
At time t1, ur transaction T1 update a block named b1. This block is copied in the rolback segment with a "non commited" status in the block header. This "before image" of ur block cannot be deleted from the RBS cause of his "non committed" status.
Ur transaction T1 now commit the modifications => the header of the block b1 in the RBS is upadted with the status "commited". Once the block has the "commited" status, he can be removed from the RBS and Oracle may remove this one if he needs some space in the RBS for some other before image.
At time t2, another transaction (named T2) start and update some rows so T2 will need some space in the RBS and then erase the version of the block b1 (in the RBS).
At time t67 (some time after), ur transaction T1 (the long one) need to read again the block b1. But as T1 has been started at time t1, Oracle will search for an image of the block b1 at time t1 (to ensure read consistency). But, as transaction T2 erased this before image of the block b1, Oracle cant find it and send u the error ORA-01555...
To avoid ORA-015[i]Long postings are being truncated to ~1 kB at this time.

Hi everybody,
I need to know how to read and interpret information from a trace file .
Is there any third party utility to convert all the information into readable text format
so that it can be easily understood.
Please help

and

You don't need a third party converter.

Hi i am using 10.2.0.4.0 version of oracle.
I am having trace file info as below, for one of the query. So how should i interpret the trace file? What is the issue in the query, and the scope of improvement in the query? please note that , i have removed the query and its plans from the trace file, i have only posted the wait sections.

I dont get any WAIT printed into the pipe file created before tracing.
Am i doing something wrong here ?
Edited by: Yasu on Nov 12, 2012 10:14 AMI tried manual method and yes i am able to find WAIT lines in trace file.

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 --

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.

Trace file errors interpretation
We are running Oracle 11.2.0.3 on a Windows 2008 R2 Server with an app server on the same. Our app has a search function that has recently started timing out on us. Sometimes intermittently but often now. I've ran a trace in our dev environment, below code, in an attempt to track down the issue but I'm finding very little useful information in relation to the errors I see in the trace file below. My experience in deciphering trace code is nill so I was hoping there would be someone out there who could elaborate a little on how they interpret these errors or provide a resource so I could do so myself. I appreciate any help provided.

Need help deleting trace files
Hi,
I am new to Oracle RAC and I need to get rid of trace files since they are growing too big. I have one that is 22Gigs and I only have 60 Gigs available right now on that drive. I want to know if I can delete the file manually using the rm command.
My trace files are in: /u01/app/oracle/diag/rdbms/.../.../trace
The file I am concerned is called: "linux1_pz99_13299.trc" and "linux1_pz99_13299.trm"
I am using Oracle 11.1.0.6.0 on Oracle Unbreakable Linux.
Thanks for any help that can be provided.Is that really going to work?
It is my understanding (supported by some inconclusive observations and experiments) that once a trace file grows beyond about 8 kilobytes Oracle will hang onto it in a death grip. You may delete it but Oracle will still have the file handle open and be writing to it.
If the database is running on a Windows platform then an equivalent script will not even give the illusion of deleting the file.
It used to be the case that switching trace file output to a different directory would cause Oracle to release the active trace files but now the trace directory is part of the ADR heirarchy so switching is a more global and more intrusive operation and could interfere with other diagnostics.
You may have to rely on ADRCI's "purge" command unless there is a PL/SQL equivalent.
I shall be very interested to see what others have to say. -
Hello,
I have from some a few doubts about the trace files, researched in various locations, but still could not solve my doubts. I hope you can help me.
First doubt:
call count cpu elapsed disk query current rows
Parse 352 0.03 0.04 0 0 0 0
Execute 434 0.05 0.05 0 0 0 0
Fetch 2359 6.97 104.50 130 460857 0 3665
total 3145 7.05 104.60 130 460857 0 3665For I know the average time of each call to this query, which account should I do?
104/434 = 0.24
104/3145 = 0.03
Another? Why?
Second doubt:
call count cpu elapsed disk query current rows
Parse 45 0.00 0.00 0 0 0 0
Execute 19232 0.79 0.92 0 0 0 0
Fetch 19232 0.90 0.90 0 0 0 19232
total 38509 1.70 1.82 0 0 0 19232How do I know how many times this query was executed?
I thought that number 19,232 too high, and I have looked at the trace file and select and only appears 41 times.
Thanks,
Everson

104/3145 = 0.03What are you trying to determine by computing such an average? The times listed are a guage to indicate how much time was spent for each operation. Apart from that the computation you listed did not look right. You dived 104 by 434 but the elapsed time for Execute was 0.05. Why did you divide the total elapsed time (assuming you did not use the elapsed fetch time) by only the Execute time when it includes the Parse and Fetch times?
The statistics listed indicate how much time was spent on each operation. Most of the time was spent in the Fetch opeation.

I thought that number 19,232 too high, and I have looked at the trace file and select and only appears 41 times.Although there might be 41 Execute operations in the raw trace file the added-up sum of the counts should be 19,232. if not then there is a problem. If you have My Oracle Support account you can log in and find a document explaining raw trace files. This information might be available on-line but is probably proprietary by oracle.

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. -

Using shared directory. Use the parameters dump to point to it
is it possible to create them on client side instead?
No
. :-) any help with my english is wellcome :-) .does this mean sharing user_dump destination at linux level and then mounting it from client machines ( win xp )?is there any doc on this? -
Name of trace file from trace enabled concurrent program
Hi all,
I am looking for a sql script or method to find the name of a trace file in udump for trace enabled concurrent programs. I know the trace files show 11i logon (user_name from fnd_user) in the name of the trace file but I am looking for a sql that would give the exact name of the raw trace file with request id as input.
I have 11.5.10.2.
Any help?

Creating trace file in oracle 10g forms
hii there,
I have developed an application in oracle 10g. but it's too slow . Now i have to trace forms . How can trace oracle forms.
please send it in details as early as possible. I don't know about this trace file generation.
-----SachinHi,
To run SQL trace for a form :
a. Get to the point in the form where you want to turn trace on.
For example, if the problem occurs on the commit, wait until you are
ready to commit, THEN turn trace on.
b. Turn tracing on. In GUI versions: Help - Tools - Trace, enable tracing.
c. Execute the steps you want to trace.
d. Turn tracing off. In GUI versions: Help - Tools - Trace, disable tracing.
The trace file will be written to the subdirectory specified in the
'user_dump_dest' parameter in the INIT.ORA file. -
Following is getting created in D:\Oracle\Ora81\DATABASE folder once or twice a month. I do not see any error entries in db1alrt.log. Please help to find out the problem.
Thanks,
Anil
