Ask result sql trace events 10046 level 8 and 12

hi all, i read result of sql trace events 10046 level 8 on

and I do sql trace event 10046 level 8 or 12. But the results did not same, execution plan does not appear
how to have execution plan appears??

We use level 12 and we have both RSO (row source operation) and execution plan. Remember, execution plan is just the preditive estimate execution path by the opimizer. RSO is actually how the optimizer executes.

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.

I am using sql trace , please tel me where i can get the value for mode of lock and type of resource.

hi,
I am using sql trace , it has cols like mode and type , but they have numbers , is there any place where i can get the metadata of these values
yours sincerley

I have already found, but the problem is, i have to put cases to show lock in fornt of numbers , what i wanted
is if i could get this mapping any where in database like( metadata is kept) , then i have to put only join.
Q2) I have one more question in which col of the event, i can have lock request status , like weather it is
granted or wait.
yours sincerly
Q1. You can create a table from the data in the link that
Ashwin Menon posted, and use simple JOIN in order to replace the numbers with the Mode
Q2. Please check this great blog:

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.

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.

Sql Trace - data lost

Could a sql trace cause a database to loose data? While running a trace, we lost data for the same period the trace was running. Please advise.
Thanks
FOP14

Pardon my inexperience, could you explain the comment, "committed data?"
By committed data, I mean either an explicit COMMIT that successfully completed or a data modification statement that completed successfully without an explicit transaction. Data modifications should be durable in either of
these cases and won't be lost even in the event of a server crash or restart because the modifications are physically written to the transaction log.
In this situation, data was being added to the database - we printed reports, "proving" data was entered. These entries occurred during the trace on several occasions,
after the trace was completed, these transactions are no longer in the database. Even assigned "account id's" for new constituents disappeared - so then when you entered a new constituent the database assigned the "used" id as the "new" id. So
id #20571 was assigned during trace and after trace it was assigned to the next candidate as if it was not used previous.
The database support team assure us the database is stable and "NOONE" else has complained of this occurrence, but we lost data. It just doesn't make sense. The only
thing different was the trace. Thanks for your help.
As long as the report queries do not specify NOLOCK or READ UNCOMMITTED, I would expect the data shown on the reports to be in the database. How exactly are the IDs assigned? Are those IDENITY column values, SEQUENCE objects, or assigned via
some other method? I'm trying to figure out what may have happened as I can't think of how a SQL trace could cause data to disappear.

Sql trace and tkprof result

When I use sql trace and tkprof. After I use tkprof, I get the result statistics. However, I don't understand one point that I see many queries which I didn't run. I mean how come these queries executed? and by who?
thanks

some could be recursive sql statemets run by oracle. Post some example what you are running and what you are seeing?
The SQL statements can be listed in a TKPROF report in the order of how much resource they used, if desired. Also, recursive SQL statements issued by the SYS user to manage the data dictionary can be included or excluded.

BDC,ALV,SQL trace

1.How can we change the language setting while uploading BDC?
2.How can we add a push button to the ALV report?
3. What is SQL Trace, how would you carried out performance analysis of ABAP code Using SQL Trace? Give the steps?

Hi
SQL Trace transaction ST05: The trace list has many lines that are not related to the SELECT statement in the ABAP program. This is because the execution of any ABAP program requires additional administrative SQL calls. To restrict the list output, use the filter introducing the trace list.
The trace list contains different SQL statements simultaneously related to the one SELECT statement in the ABAP program. This is because the R/3 Database Interface - a sophisticated component of the R/3 Application Server - maps every Open SQL statement to one or a series of physical database calls and brings it to execution. This mapping, crucial to R/3s performance, depends on the particular call and database system. For example, the SELECT-ENDSELECT loop on a particular database table of the ABAP program would be mapped to a sequence PREPARE-OPEN-FETCH of physical calls in an Oracle environment.
The WHERE clause in the trace list's SQL statement is different from the WHERE clause in the ABAP statement. This is because in an R/3 system, a client is a self-contained unit with separate master records and its own set of table data (in commercial, organizational, and technical terms). With ABAP, every Open SQL statement automatically executes within the correct client environment. For this reason, a condition with the actual client code is added to every WHERE clause if a client field is a component of the searched table.
To see a statement's execution plan, just position the cursor on the PREPARE statement and choose Explain SQL. A detailed explanation of the execution plan depends on the database system in use.
SQL Trace ST05
Starting the Trace:
To analyze a trace file, do the following:
Choose the menu path Test  Performance Trace in the ABAP Workbench or go to Transaction ST05. The initial screen of the test tool appears. In the lower part of the screen, the status of the Performance Trace is displayed. This provides you with information as to whether any of the Performance Traces are switched on and the users for which they are enabled. It also tells you which user has switched the trace on.
Using the selection buttons provided, set which trace functions you wish to have switched on (SWL trace, enqueue trace, RFC trace, table buffer trace).
If you want to switch on the trace under your user name, choose Trace on. If you want to pass on values for one or several filter criteria, choose Trace with Filter. Typical filter criteria are: the name of the user, transaction name, process name, and program name.
Now run the program to be analyzed.
Stopping the Trace:
To deactivate the trace:
Choose Test Performance Trace in the ABAP Workbench. The initial screen of the test tool appears. It contains a status line displaying the traces that are active, the users for whom they are active, and the user who activated them.
Select the trace functions that you want to switch off.
Choose Deactivate Trace. If you started the trace yourself, you can now switch it off immediately. If the performance trace was started by a different user, a confirmation prompt appears before deactivation-
Analyzing a Sample trace data:
PREPARE: Prepares the OPEN statement for use and determines the access method.
OPEN: Opens the cursor and specifies the selection result by filling the selection fields with concrete values.
FETCH: Moves the cursor through the dataset created by the OPEN operation. The array size displayed beside the fetch data means that the system can transfer a maximum package size of 392 records at one time into the buffered area.

Sql trace (st05)

hi friends
.pls tell in detail how to evaluate the performance of one select querry by using sql trace.( pls tell all traces )

Kumar,
SQL Trace
SQL trace(ST05) provides the developer with the ability to analyse database select statements. Simply execute ST05
to turn on SQL trace, then execute the statement/program you want to analyse. Now turn off SQL trace using ST05
and click on list trace to view the details.
You can also perform traces on other items such as authorisation objects.
Authorisation trace analysis 1. Open two sessions
2. Execute transaction ST01 in one of the sessions
3. Select the authorisation checkbox, note the other traces
you can perform (SQL, RFC, Table Buffer etc)
4. Click the 'Trace On' button
5. Within your other session execte 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 athorisation 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

Some useful transaction related to this are ..
ST01 SAP system trace
ST02 Buffer statistics.
ST03 Workload analysis.
ST04 Database performance analysis.
ST05 SQL trace .
ST06 Operating system monitor ...
From the recorded SQL trace you can deduce:
· Which SQL statements your application carries out
· Which values the system uses for specific database accesses and changes
· How the system translates ABAP OPEN SQL commands (such as
SELECT) into standard SQL commands
· Where your application positions COMMIT statements
· Where your application makes repeated database accesses
· What database accesses or changes occur in the update section of your
application

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/TKPROF VS SQL ACCESS ADVISOR

Hi All,
Can anyone please tell me what's the exact difference between SQL TRACE/TKPROF and SQL ACCESS ADVISOR in Oracle 10g.(By showing some examples)
And also why should I go for SQL ACCESS ADVISOR ?? (Since I have used the former all these days) :)
Why can't I still use SQL TRACE/TKPROF.
Please if anyone can pour light on this. Thanks in Advance.

Run time analysis transaction SE30 :This transaction gives all the analysis of an ABAP program with respect to the database and the non-database processing.
STEPS
Run time analysis transaction SE30
In Transaction SE30, fill in the transaction name or the program name which needs to be analyzed for performance tuning.
For our case, let this be ZABAP_PERF_TUNING
After giving the required inputs to the program, execute it. After the final output list has been displayed, PRESS the BACK button.
On the original SE30 screen, now click on ANALYZE button.
The percentage across each of the areas ABAP/ Database/System shows the percentage of total time used for those areas and load on these areas while running the program . The lesser the database load faster the program runs.
