hi all
i read some articals of how to trace oracle sessions and i have some question
i use database 10g
trace vs event ??? different between them ????
how to trace individual statement i hope to give me this point in ex:
due to i can't get the sql_id ,how to know the sql_is of specify statement??

How to set SQL trace in OCI session ?

Hello,
In a SQL*Plus session, I can use the SQL statement "alter session set sql_trace=true;" to set SQL trace in that session only. I assume I could execute the same SQL statement from C code in an OCI client and achieve the same goal.
However, if I cannot change the code of this OCI client, is there a way to set SQL trace for that single session alone, without changing the C code? Say, through an environment variable, configuration file, etc.?
Thanks.

I am not aware of a way to selectively enable the server-side tracing without modifying the client code.
There is client tracing available by setting the environment variable EVENT_10842 as follows:
"server=<>;user=<>;stmt=<>;level=<>;interval=<>"
e.g.
setenv EVENT_10842 "server=inst1,inst2;user=scott,system;stmt=all;level=15"
Where:
"server" is a comma separated list or "all"
"user" is a comma separated list or "all"
"stmt" can be INSERT,UPDATE,DELETE,SELECT or "all"
The following levels are supported:
1 - Trace all server attach and server detach calls for servers listed in "server" attribute of the environment variable.
2 - Trace all session begin, logon, session end, logoff calls for the users listed in "user" attribute of the environment variable.
3 - Trace all prepare, execute, fetch calls for the specified statement types listed in "stmt" attribute of environment variable.
4 - Trace all Bind, Define, Describe calls.
5 - Trace all OCI LOB calls
7 - Get statistical info on all connection pooling /connection related calls
8 - Get statistical info on all session info
9 - Get statistical info on all handle info
10 - Get statistical info on time taken in execute and fetch calls
11 - Get statistical info on transaction related calls
15 - Trace all calls with statistical info.

Automize SQL TRACE for a selected session

Hi,
Should I automize the process of SQL Tracing for a particular session of our choice?
Lets say when there are several sessions, and we want to select the particular session for SQL TRACING, then the SQL tracing for that session enable via running a routine.
I used AFTER LOGON trigger for enabling SQL trace, but using this approach enable SQL TRACING all the sessions.
My Logon Trigger for enabling SQL Tracing:
create or replace trigger LOGON_SQL_TRACE
after logon on database
begin
execute immediate
'alter session set sql_trace=true';
end;
I want to use a perfect routine that first get the sid, serial# or username etc. from V$session, V$process or else, and then enable the SQL TRACING for the selected session.
Like SYS.DBMS.SYSTEM.SET_SQL_TRACE_IN_SESSION package is available for doing that or may be some others as well.
But how should we use these packages or other SQL tracing commands in a routine, which we can use for, enable SQL Tracing implicitly.
Any ideas will be great.
Bill

SYS.DBMS.SYSTEM.SET_SQL_TRACE_IN_SESSION is just fine.
You can get the SID and SERIAL# from v$session; you just have to know the username, osmachine, the OS process, ...

Ability to perform ALTER SESSION SET SQL TRACE but not all alter clauses

I see that in order to run the ALTER SESSION SET SQL TRACE command, the user should be explicitly granted alter session privilege as the CREATE SESSION privilege alone is not enough. Is there a way to grant the ability to perform ALTER SESSION SET SQL TRACE but not the other clauses such as GUARD, PARALLEL & RESUMABLE?.
Thanks
Sathya

If you are using Oracle 10g and above, you can use DBMS_SESSION.session_trace_enable procedure,
it doesn't require alter session system privilege.
Simple example:
SQL> connect test/test@//192.168.1.2:1521/xe
Connected.
SQL> alter session set tracefile_identifier='my_id';
Session altered.
SQL> alter session set sql_trace = true
2 ;
alter session set sql_trace = true

DBMS_SYSTEM : 다른 USER나 SESSION에 SQL TRACE 걸기

제품 : SQL*PLUS
작성날짜 : 2002-04-12
DBMS_SYSTEM : 다른 USER나 SESSION에 SQL TRACE 걸기
==================================================
Purpose
DBA user등에서 일반 user가 실행하는 sql의 trace를 떠 보고 싶은
경우가 있다. 이렇게 다른 user session에 sql trace를 받을 수 있는
방법에 대해 알아보자.
Explanation
SQL*Plus에 접속하여 SQL trace를 거는 것이 아니라 DBMS_SYSTEM package를
이용하여 다른 유저나 다른 세션에서 특정 세션을 지정하여 SQL trace를 걸
수 있다.
( DBMS_SYSTEM package는 Oracle 7.3부터 사용할 수 있다. )
DBMS_SYSTEM package를 사용하기 위해서는 먼저 다음의 script를 실행한다.
$ cd $ORACLE_HOME/rdbms/admin
$ sqlplus sys/manager
SQL> @dbmsutil
SQL> @prvtutil.plb
dbmsutil.sql file은 sys user나 svrmgrl 에서 실행시킨다.
이 package를 다른 유저에서 실행하려면 미리 grant를 주어야 한다.
$ sqlplus sys/manager
SQL> grant execute on dbms_system to system;
[ DBMS_SYSTEM package ]
- DBMS_SYSTEM.set_sql_trace_in_session(sid, serial#, TRUE)
지정된 session에 대해 SQL trace를 실행하여 user_dump_dest parameter에
지정된 위치에 trace file이 생성된다.
- DBMS_SYSTEM.set_sql_trace_in_session(sid, serial#, FALSE)
지정된 session에 대한 SQL trace를 해제한다.
Example
system user에서 scott user를 지정하여 SQL trace를 건다.
sqlplus system/manager
SQL> select sid, serial#
from v$session
where username = 'SCOTT';
SID SERIAL#
8 12
SQL> exec sys.dbms_system.set_sql_trace_in_session(8, 12, TRUE);
-> scott user에 대한 SQL trace가 실행된다.
SQL> exec sys.dbms_system.set_sql_trace_in_session(8, 12, FALSE);
-> scott user에 걸린 SQL trace가 해제된다.
참고 :
Dedicate 방식으로 접속한 user는 user_dump_dest/ora_processid.trc로
생기며, MTS 방식으로 접속한 user에 대해서는
background_dump_dest/s000_22509.trc 와 같이 MTS server name으로
생성된다.
또한, 위 경우 모두 trace file을 한번 삭제한 후에 다시 그 process를
사용하는 session에 대해 trace를 걸면 trace file은 생기지 않는다.

OCCI/ODBC application sql trace failure...

Hi,
I was doing the sql*net trace for an OCCI/ODBC Application writen in c++. I have an InstantClient on my PC. I was trying to access the Oracle through my C++ program to
compare the performance of OCCI and ODBC.
I was using the Oracle 10g(ver10.2.0.1.0 ), Oracle instant cilent(win32-10.2.0.3-20061115), and VS 8.0.
TNSNAMES.ora:
ORCL =　　
　　(DESCRIPTION =
　　(ADDRESS_LIST =
　　(ADDRESS = (PROTOCOL = TCP)(HOST = host_name)(PORT = 1521))
　　(CONNECT_DATA =
　　(SERVER = DEDICATED)
　　(SERVICE_NAME = ORCL)
(SID = ORCL)
LISTENER.ORA:(It was created by net manager.)
SID_LIST_LISTENER =
　　(SID_LIST =
　　(SID_DESC =
　　(GLOBAL_DBNAME = ORCL)
　　(ORACLE_HOME = F:\oracle\product\10.1.0\Db_3)
　　(SID_NAME = ORCL)
LISTENER =
　　(DESCRIPTION =
　　(ADDRESS = (PROTOCOL = TCP)(HOST = HOST_NAME)(PORT = 1521))
The sqlnet.ora file was writen to trace the client sql. Fortunately, my C++ program can access the oracle and get my result back successfully. In the same time, the trace files
can be created, but when using the tkprof tool to explain it, it comes to the file with useless information.
One of the *.trc file explaind by tkprof tool:
Sort options: default
count = number of times OCI procedure was executed
cpu = cpu time in seconds executing
elapsed = elapsed time in seconds executing
disk = number of physical reads of buffers from disk
query = number of buffers gotten for consistent read
current = number of buffers gotten in current mode (usually for update)
rows = number of rows processed by the fetch or execute call
Trace file: ora21763.trc
Trace file compatibility: 8.00.04
Sort options: default
1 session in tracefile.
0 user SQL statements in trace file.
0 internal SQL statements in trace file.
0 SQL statements in trace file.
0 unique SQL statements in trace file.
327 lines in trace file.
Finally, I got TNS-12518 TNS-12564 error. I tried to add DIRECT_HANDOFF_TTC_LISTENER=OFF, but it didnt work. I traced the listener, the error occured in the listener.trc "
ntt2err: soc 464 error " and " nsbequeath: error reading REDIR/NSE msg".
I just cann't get the right trace file and cann't sovle the two errors(TNS-12518 TNS-12564). Can somebody give me some advices, please.

Hi,
The TKPROF facility accepts as input an SQL trace file generated when SQL Trace has been turned on for the system or a session, not a SQL*NET trace file. A SQL*Net trace file is a dump of raw data packets and communications at the SQL*NET layer. If you want to get performance statistics from SQL beign executed by your application, then you need to turn on SQL Trace not SQL*MET tracing.
To enable SQL trace at the system level, you need to execute:
alter system set SQL_TRACE=TRUE
The NS-12518 TNS-12564 normally means you are running into some sort of resource deletion issue. This can be caused by various things. Make sure you are properly cleaning up and closing sessions in your application.
Are you performing some sort of stress test or have you just written a Multi-threaded test harness that executes different types of SQL with OCCI/ODBC?

Generate Sql Trace in oracle reports

Hi,
My Reports version is 10.1.2.0.2 and I would like to see the trace files of the sql queries that are executed while generating a report using rwbuilder.
I tried using a Formula column, with
SRW.DO_SQL('ALTER SESSION SET SQL_TRACE=TRUE');
return(1);
Also, I enable system level trace to capture anything and everything that is being fired into DB from reports.
I tried,
ksh rwthinclient.sh report=$REPORT_FILE_PATH/Journal.rdf server=$REPORT_SERVER userid=$ORAUSERID/$ORAPASSWD@$REPORT_DATABASE destype=cache desformat=pdf TRACEFILE=ver1.trc TRACEOPTS=trace_all TRACEMODE=trace_replace RUN_DATE=$CurDate;
I do not get trace at all. Kindly help me out.

Hi,
Maybe have a look at this MOS note: Running SQL*Trace on an Applications Report [ID 1019231.6]

SQL TRACE for WEB deployed report

When I put
Alter Session Set sql_trace=TRUE
into the BEFORE Parameter Form trigger...
I get a trace file showing data on the one SQL in that trigger.
There is no TRACE output of the main query or any of the PL/SQL in the Program Units.
The report is invoked from company-wide intra-net.
I think it is Oracle Apps running in Linux server.
What am I doing wrong?
PS
I cannot execute this report from Report Builder.

Hello,
Just a remark : if you are using Reports 9.0.4 / 10.1.2, you don't have to modify the reports , you can activate the SQL trace with the parameter SQLTRACE=YES

SQL Trace for schema level

Hi
Database 10.1.0.4
Sql trace file which I have used but didn't get the trace file. I have tried to get per session Id but not able to get the trace file, when ever user logged into application, virtually 6 user get lgged in and you never know about user. So I have desided to capture for schema
I have used this for tracing
SQL> ALTER SESSION SET sql_trace=TRUE;
SQL> ALTER SESSION SET sql_trace=FALSE;
Or
SQL> EXEC DBMS_SESSION.set_sql_trace(sql_trace => TRUE);
SQL> EXEC DBMS_SESSION.set_sql_trace(sql_trace => FALSE);
or
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);
I want to get trace file for schema, can anyone suggest how do I get trace file at schema level.
Thanks for help

Hi,
Using instance-level tracing by setting the init.ora/spfile... parameter SQL_TRACE=TRUE, all processes against the instance will create their own trace files. This particular method of tracing should be used with care since it creates a great deal of overhead against the system. In addition, the default value for this parameter is FALSE.
Cheers

SQL Trace and Bind Values

I need to capture bind values in SQL Trace. I am running Oracle 9.2.0.8. I will be running my queries from an application, not SQL Plus. I can use a after log on trigger to turn on trace. Has anyone done this with success? Are there any other ways to do this at the server level?
Thank you for your input
David

Hello David,
it is such easy ... you wouldn't believe it.
Have a look at the pl/sql procedure "dbms_system.set_ev", with this one you can do this on session level: http://www.oracleadvice.com/Tips/dbms_system.htm#SET_EV
There are also some other possibilities... but this should hit your question..
To turn on:
SQL> exec dbms_system.set_ev(<SID>, <SERIAL>, 10046, 12, '');
To turn off:
SQL> exec dbms_system.set_sql_trace_in_session(<SID>, <SERIAL>, FALSE);

Stefan

Hi,
i did the homework, but some how i dont seem to understand what oracle is doing behind
esp with hints like
select /*+ leading(v1 v2) use_nl_with_index(v2) */ count(v1.val)
/*+ no_parallel(t) no_parallel_index(t) dbms_stats
cursor_sharing_exact use_weak_name_resl dynamic_sampling(0) no_monitoring
substrb(dump(min("XXX"),16,0,32),1,120),
substrb(dump(max("XXX"),16,0,32),1,120),i havent used this things any where in my program, but still they are used,
so i got confused, can you throw some light on this issue,
regards

How to use Sql Tracer

Hi ,
How to use SQL Tracer..(ST05).
Thanks,
Subbu

Hi,
ST05: SQL trace
1.create a small ABAP/4 program that contains only the select statement. Before proceeding, test it to ensure that it works.
2.Open that program in the editor so that it is ready and waiting to execute.
3.Open a new session using the menu path System->Create session.
4.Run transaction ST05 (enter /nst05-zero-five, not oh-five-in the Command field, or choose the menu path System->Utilities->SQL Trace). The Trace SQL Database Requests screen is displayed.
5.If the Trace SQL Status Information box reads Trace SQL is switched off, go to step 7.
6.At this point, the Trace SQL Status Information box contains Trace SQL switched on by, followed by the user id who turned on the trace and the date and time it was started. You must switch it off before you can proceed. If the trace was started within the past hour, it is possible that it is still being used. Contact the indicated user or try again later. If the trace was started hours or days ago, the user probably left it on by mistake and it can be safely turned off. To turn off the trace, press the Trace Off pushbutton. The message in the Trace SQL Status Information box should now read Trace SQL is switched off.
7.Press the Trace On pushbutton. The Trace SQL Database Requests dialog box is displayed. The DB-Trace for User field should contain your user ID. If your user ID is not in this field, enter it now.
8.Press the OK button. You are returned to the Trace SQL Database Requests screen and the status information reads Trace SQL switched on by, indicating that you turned on the trace.
9.Switch back to the window containing your editor session (the one with your program waiting to execute).
10.Press F8 to run your program. (Only press F8, do not do anything else, do not even press the Back button.)
11.When your program has run and the hourglass is no longer displayed, switch back to the trace window.
12.Press the Trace Off pushbutton. The status information reads Trace SQL is switched off.
13.Press the List Trace pushbutton. The Trace SQL Database Requests dialog box is displayed. The fields on this screen will already contain values.
14.Press the OK button. You might need to wait a little while, at most a couple of minutes. The Trace SQL: List Database Requests screen is displayed.
15.Type %sc in the Command field and press the Enter key. The Find dialog box is displayed.
16.Type the name of the table you are tracing in the Search For field. (This is the table named in the select statement in your ABAP/4 program.)
17.Press the Find button. A search results list should be displayed with your table name highlighted.
18.Click on the first highlighted table name. You are returned to the Trace SQL: List Database Requests screen. Your cursor is positioned on the first line containing your table name. To the right of it, in the Operation column, should be the word PREPARE, OPEN, or REOPEN.
19.Press the Explain SQL button on the Application toolbar. The Show Execution Plan for SQL Statement screen is displayed.
20.Scroll down to the execution plan. The index used will be displayed in blue.

Regarding SQL trace

Hi all,
I want to run a SQL trace for processing of CREMAS IDOC's ( custom Functional module) and i want to see which all tables or SQL statement is taking more time .
Can you tell me procedure to run SQL trace.

HI,
Here are the 2 good links
http://publib.boulder.ibm.com/tividd/td/ITMAN/SC32-9195-00/en_US/HTML/sap_add06.htm
http://help.sap.com/saphelp_webas610/helpdata/en/d1/8022e5454211d189710000e8322d00/content.htm
Well using SQL trace
like as follows:
Goto transaction ST05. Press TRACE ON.
Execute your transaction .
Come back to this screen and click TRACE OFF.
Then check the trace details.
You end up getting unnecessary details
Lets say you have to analyze your particular SQL query,
1. put a breakpoint at the select statement and execute the transaction , as it stops at your breakpoint , run SQL trace in seperate session.
2. Trace ON
3. Execute the select statement.
4. Trace OFF
5. Analyze.
In this way you can analyze your particular select query
Pls check links like:

SQL Trace
SQL trace (ST05) provides the developer with the ability to analyze database select statements. Simply execute ST05 to turn on SQL trace, then execute the statement/program you want to analyze. Now turn off SQL trace using ST05
And click on list trace to view the details.
Authorization trace analysis
1. Open two sessions
2. Execute transaction ST01 in one of the sessions
3. Select the authorization checkbox, note the other traces
you can perform (SQL, RFC, Table Buffer etc)
4. Click the 'Trace On' button
5. Within your other session execute the transaction/report
you want to trace or get the user in question to do it
6. Return to the session where you turned the trace on and
click on 'Trace Off' otherwise it will continue to record all authorization checks
7. Click on the 'Analysis' button
8. Enter appropriate data into selection screen such as
Username, type of trace records (i.e. Authorization check)
9. Click on the Execute button.
10. Report displaying trace results will now be displayed

SQL Trace over JDBC

I'm not sure if this is possible but I'm looking to retrieve a running total of the number of rows processed by the OLAP option without polling the "longops" dynamic management view. As such, is it possible to set a SQL Trace running but rather than spooling the results to a file, return them over the JDBC connection for the client application to interpret? (I am naturally assuming here that it is possible to get this "running information" from a SQL trace for a given session ID. If not, the question is moot I guess...
I am using 11.1.0.7.0.
Thanks for any help.

Hi
Whether if you use Sender or Receiver communication channel, SAP PI always open the connection to remote server. That is, SAP PI is always the component client, therefore the only thing you should to open is the MS SLQ port.
