No trace file produced
I am try to trace a page in my application using &p_trace=YES. I have added to the url and run the page. I have checked the location that trace files are saved to using show parameter USER_DUMP_DEST. I have navigated to the directory but no trace files has been produced. I'm using Apex 3.1 and Oracle XE.
Any ideas?
Thanks
Ian
I have found it The trace file was in bdump not udump which user_dump_dest points to

Hi,
I've gotten a bunch of deadlocks in 8.1.7 and I'd like to be able to make use of the trace files, but the files are really cryptic and I can't find any documentation anywhere that explains how to read them. Moreover, I can't find any software that knows how to process them into something useful (tkprof just gives a basically empty file in return).
Anyone have any ideas?
TIAHi
My current application (still under development) is experiencing Oracle
deadlock problems.
The application is written using VB thru ADO and COM, Oracle 816.
My problem is that, while I can review the trace file produced, I can't
figure out what the actual deadlock is occurring on. I have seen deadlock
trace files that clearly state "table blah", but in this case, I get:
*** 2003-06-21 14:32:03.841
*** SESSION ID:(27.31211) 2003-06-21 14:32:03.810
DEADLOCK DETECTED

Is there something like TKPROF that will process the trace file and give
me
more info on what is happening? It looks like I am waiting for a resource
to be freed, but which one is the question.
thanks for any help. -
Gather Schema Statistics produces HUGE oracle trace file
Hi
I am running gather schema stats on my E-Biz 12.1.3 / 11.2.0.3 system
Each week we run Gather Schema Stats
I have noticed that when the job completes a 3g trace fuile is produced under the Oracle RDBMS home
I have tried un-checking the box when the COnc Request is submitted to DO NOT SAVE OUTPUT FILE but it is still procuced.
I dont want it and do not understand why it is produced. Anyone out there have a resolution?I have noticed that when the job completes a 3g trace fuile is produced under the Oracle RDBMS homeWhat is the file name/location? What is the contents of this trace file?
I have tried un-checking the box when the COnc Request is submitted to DO NOT SAVE OUTPUT FILE but it is still procuced.Do you have any debug/trace enabled on HRMS schema?
I dont want it and do not understand why it is produced. Anyone out there have a resolution?Was this working before? If yes, any changes been done since then?
What are the parameters you use to run "Gather Schema Statistics" concurrent program?

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? -
Explain Plan from TKPROF trace file.
Hello,
My procedure is taking time for that i have trace on in procedure fo find explain plan of particular query.
Using below statement Trace is on.
EXECUTE IMMEDIATE 'ALTER SESSION SET SQL_TRACE = TRUE';
EXECUTE IMMEDIATE 'ALTER SESSION SET TIMED_STATISTICS = TRUE';Now for getting expalin plan from TKPROF i have used below statement but for some query i have found explain paln and some case i cant found explain plan.
tkprof mf_ora_23773.trc mf_ora_23773.txt explain =abc/abc
can u please help me to analyze where i m wrong?
Thanks.First of all, you should best avoid using the explain= clause on the tkprof command line.
This will run explain plan on the statement in the trace file, and that explain plan can even be wrong, as there is no information on datatypes in the trace file.
The real explain plan data is flushed to the trace file, when the program issues commit or rollback. Oracle always issues an implicit commit when the program disconnects, so when you run the program to completion you should have explain plan output in your trace files.
You won't get explain plan output if you don't have access to the objects in the SQL statement. Also recursive SQL won't produce explain plan result.
One would need to see part of your trace file to verify your assertion the explain clause doesn't always work.

Trace files showing bind variables value=""
10g on solaris
Hi All,
We have an issue with an informatica workflow issuing an update statment to Oracle in trems of performace.
I switched the tracing on using DBMS_SUPPORT with binds set to TRUE. It has captured the trace files accordingly against a controlled set of data. Twot trace files were produced.
The first trace files shows the SELECT statment being issues that identifies the records that will be updated.
The 2nd trace file shows the actual UPDATE statment being issued as a PL/SQL loop to do the update.
There were 20 records that the users have rigged to updated and the update statment shows 20 cases where updates took place. All updates took place succesfully after checking the post results. However my issue is why the trace files are showing the bind vaules as being set to ""?..any ideas appreciated!
an extract of the trace file...

Having investigated on the comment of NVARCHAR2 not allowing bind variables to be displayed in the trace file... I checked the datatype of the table/column being used in the index and its is defined as VARCHAR2(15)... ? so Im still not sure as to why we are still getting this.. could it be to do with the clinet application and the way in which it passes the bind vlaues to the oracle update statment?
any ideas appreciated?

The script:

ALTER SESSION SET EVENTS '10046 TRACE NAME CONTEXT OFF';In the script we have two bind variables defined, the first a VARCHAR2 and the second a NVARCHAR2. The output of the script looks like this in both cases:

To answer your question, it is the client application that must correctly define the bind variable types.

Trace file generation using oradebug

OS : Solaris 5.10
I am trying to trace a session started by a Java application.
So, i've logged in as SYS. Got pid, spid from v$process. Then started the debug
SYS@MN_PROD>oradebug setospid 2523
SYS@MN_PROD>oradebug event 10046 trace name context forever, level 32and closed it using
oradebug event 10046 trace name context offWhen i type
ORADEBUG TRACEFILE_NAMEIt shows a filename in bdump directory. But i can't find this file in bdump or udump.
Is there any init.ora setting i need to do to get this file generated?Decimal Binary Description
1 0001 Emit statistics for parse, execute, fetch, commit, and rollback database calls (standard sql_trace)
2 0010 Unknown
4 0100 Emit values for SQL bind variables (also called “placeholders”)
8 1000 Emit statistics for Oracle kernel internal function calls (also called “wait events”) listed in v$event_name
These levels can be combined as if by a bitwise or function to produce combinations of data in an Oracle trace file.

hello,
i checked the following url:
http://technet.oracle.com/doc/reports25/ormc2/ch1.htm#toc009
there i read about the error messages that could occur during
report generation:
there are types like:
REP
ORA
DBA
EXP
IMP
and so on ...
could anybody post trace-files where some of these error occur ?
since months i am trying to get an answer to the following message:
is there any save way to identify ALL error messages in a trace file ?
Or is there any trigger which fires if an error during report generation occurs ?
many thanks for any help
greetings from berlin
thorsten lorenzhello,
thank you for your answer.
but what if i want to get trace-file data
and error-data ? i am using "oracle reports 6".
it seems to me if one can get only trace-data OR
error-data (or am i wrong ?)
if "ORA" and "REP" messages can occur, which error-types could further occur ?
in oracle documentation there is the word "system-specific" message.
but what is the format of such system-specific-message ? does
it begin with "System-specific" ? i can't produce such a message ...
identfication of ORA and REP messages is easy. but what if i want to
get ALL error-messages in a safe manner ? the parser would look for ORA
and REP but for what things else the parser should search ?
or are there errors-messages which can't be predicted ?
any ideas ?
i saw a trace file of oracle reports version 9, too.it seems
those trace files are better structured ...
greetings

Capturing errors in trace file
If I intentionally out a error in report and run it through report bulider, the trace file shows proper errors.
But, If I try to run it from command prompt, it produces the trace file but dosen't give error information. I have tried giving TRACEOPT = TRACE_ALL. and all other trace options. Do we have any other way to capture errors in report.?
My reqirement is to log the errors produced in the report to a table, and find out the successful execution of the report.Hi All ,
MY database is oracle 11G , SParc OS 64 Bit , i got the same error on my primary database.
Please find the exact error below :
KQRCMT: Write failed with error=604 po=3ebb848b0 cid=13
diagnostics : cid=13 hash=d906a6b flag=2a
KQRCMT: Write failed with error=604 po=3ebb848b0 cid=13
diagnostics : cid=13 hash=d906a6b flag=2aThat is the only error in the trace file.
i have checked on google and metalink but not much is available.
please suggest
Thanks

Trace file of directory /ORACLE/ SID /SAPTRACE/USERTRACE increase ceaseless
Dear all,
Now I face a problem that the Trace file of directory /ORACLE/<SID>/SAPTRACE/USERTRACE increase ceaseless and very quickly, the trace files size was increased to 8G only two days, so the directory always is full due to this.
So anybody could tell me this is why ? and what method could help to decrease the trace log to produce ?
Thanks & Regards,

Thanks for your reply, I saw the notes and use Transaction SM50 to check the trace level, the level is default ,
this system is our solution manager, although the directory is full but the system still could be connected.
The trace files contents as below：

Strange trace files after code generation! Are they generated by XText?
We have a DSL from which we generate C-Code (.c and .h files). The project build (especially on Windows platform) is very slow mainly due to refreshing and indexing (by Eclipse CDT) mysterious trace files.
Currently we don't know which part of the framework is responsible for generating these trace files (CDT, XText, Eclipse, whatever ...).
We were not able to analyse the content of the trace file, since none of the files appear at the file system.
The filename syntax is as follows:
For a C source code file "/project/src-gen/my_c_function.c" the following trace file gets generated: "/project/src-gen/.my_c_function.c._trace"
Does anybody know if XText is responsible for this ?Hi
Sounds like a bad bug. I would progress in two ways.
Load EGIT as source and profile to see where the time goes.
Use Wireshark to see if unexpected Internet traffic is occurring quite
possibly with long timeouts.

I am beginner in oracle and i need to analyze the trace file, i have traced a session and converted the raw trace file into txt and html file using trace analyzer ,but after that how can i read or identyify which one produces a problem.
Please anyone suggest me .
Thanks in advance

I have a Db package and want to get actual execution plan of all the statements in that pakcage it does provides the plan for System's statements but does not displays the plan for Sql statements

end;
alter session set sql_trace=false;
exit; ---exit from Sql

How to create the trace file using run_report_object at runtime
Dear All
using :
Oracel Application Server 10g
Oracle Database 11g
Windows XP/sp3
I'm using run_report_object to call a report inside the form. THis report is running OK from reports builder, however it's too slow when run from Application server.
How Can I create a trace file (at runtime) that contains the time spent in sql and formating the layout of the report ??
Here is My code :
repid := find_report_object('report5');
SET_REPORT_OBJECT_PROPERTY(repid,REPORT_FILENAME,'INVOICE.REP');
v_url :='paramform=no';
v_url := v_url||' FROM_NO=' || :PRINT_BLOCK.FROM_NO ;
v_url := v_url ||' TO_NO=' || :PRINT_BLOCK.TO_NO ||' FROM_DATE=' || v_from_date ||' TO_DATE='|| v_to_date ||' NO_DATE=' ;
v_url := v_url ||:PRINT_BLOCK.NO_DATE||' IDENT=' ||:PRINT_BLOCK.IDENT_NO||' REPORT_HEADING='''||V_REPORT_HEADING||'''' ;
v_url := v_url||' COMPANY_NO='||:global.company_no;
SET_REPORT_OBJECT_PROPERTY(repid,REPORT_OTHER,v_url);
SET_REPORT_OBJECT_PROPERTY(repid,REPORT_SERVER,:GLOBAL.INV_REPORT_SERVER_NAME);
SET_REPORT_OBJECT_PROPERTY(repid,REPORT_DESFORMAT,'pdf');
v_rep := RUN_REPORT_OBJECT(repid);
IF rep_status = 'FINISHED' THEN
V1:='/reports/rwservlet/getjobid'||substr(v_rep,instr(v_rep,'_',-1)+1);
WEB.SHOW_DOCUMENT('/reports/rwservlet/getjobid'||substr(v_rep,instr(v_rep,'_',-1)+1)||'?server='||REPORT_SERVER_NAME,'_blank');
END IF;
Thanks a lotSlow running reports often are not the result of a flawed report, but rather a flawed configuration. For example:
1. If you call your reports (from Forms) via the default or inProcess Reports Server, often because startup time is slow, it will appear that it took too long for the report to be delievered. Using a stand-alone Rep Server is the preferred way to do this.
2. If your Forms application makes numerous calls to RRO (RUN_REPORT_OBJECT), this can tend to result in what might appear as a memory leak (although it is not). The result is delayed processing because of the excessive memory use. This problem has been overcome in Forms/Reports 11 by the use of JVM pooling. However in v10 enabling "6i compatibility" mode is the way to overcome the issue. See Note 266073.1
3. If the report runs fine from the Builder and it is connecting to the same db as when you run it from App Server, the issue is unlikely a db problem. However, if you want to look anyway, enable sqlnet tracing.
4. To enable Reports tracing and investigate other tuning options, refer to the Reports 10 documentation:
http://docs.oracle.com/cd/B14099_11/bi.1012/b14048/pbr_tune.htm
Almost forgot to mentioned this one....
If you are using a v11 db with App Server 10, you will probably want to consider reviewing Note 1099035.1 as it discusses an issue related to performance with such a configuration.

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.
