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

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

Hi
these all are doing t he same thing that is checking the program for better performance
Tools for Performance Analysis
Run time analysis transaction SE30
SQL Trace transaction ST05
Extended Program Check (SLIN)
Code Inspector ( SCI)
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.
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.
Extended Program Check
This can be called in through transaction SE38 or through transaction SLIN. This indicates possible problems that may cause performance problems.
Code Inspector (SCI)
You can call the Code Inspector from the ABAP Editor (SE38), the Function Builder (SE37), the Class Builder (SE24), or as a separate transaction (SCI).
The Code Inspector indicates possible problems. However, note that, especially with performance issues: There is no rule without exception. If a program passes an inspection, it does not necessarily mean that this program will have no performance problems.

SQL Trace(ST05) and Run Time Analysys(SE30)

Hi ABAP Experts,
Can any one explain what is the use of

Hi,
The SQL Trace part of the Performance Trace tool allows you to see how the OPEN SQL statements that you use in ABAP programs are converted to standard SQL statements (see Embedded SQL) and the parameters with which the embedded SQL statements are passed to the database system.
Overview
From the time you turn on the trace function to the time you turn it off again, all database activity occurring either for a specific user or for an entire system is recorded. The SAP System takes OPEN SQL statements and converts them in to embedded SQL statements that it passes to the database and makes the results available. The embedded SQL statement and its parameters are recorded in the SQL Trace file. The results of the SQL statement, like return code, number of entries retrieved, inserted, or deleted by the database are recorded in the SQL Trace file as well. The log file also contains the runtime of the statement and the place in the application program, respectively transaction, from which it was called which enables additional analyses (supported by the SQL Trace function).
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
Create a Trace (SQL Server Profiler)
To create a trace
On the File menu, click New Trace, and connect to an instance of SQL Server.
The Trace Properties dialog box appears.
Note:
The Trace Properties dialog box fails to appear, and the trace begins instead, if Start tracing immediately after making connection is selected. To turn off this setting, on the Tools menu, click Options, and clear the Start tracing immediately after making connection check box.
In the Trace name box, type a name for the trace.
In the Use the template list, select a trace template on which to base the trace, or select Blank if you do not want to use a template.
To save the trace results, do one of the following:
Click Save to file to capture the trace to a file. Specify a value for Set maximum file size. The default value is 5 megabytes (MB).
Optionally, select Enable file rollover to automatically create new files when the maximum file size is reached. You can also optionally select Server processes trace data, which causes the service that is running the trace to process trace data instead of the client application. When the server processes trace data, no events are skipped even under stress conditions, but server performance may be affected.
Click Save to table to capture the trace to a database table.
Optionally, click Set maximum rows, and specify a value.
Caution:
When you do not save the trace results to a file or table, you can view the trace while SQL Server Profiler is open. However, you lose the trace results after you stop the trace and close SQL Server Profiler. To avoid losing the trace results in this way, click Save on the File menu to save the results before you close SQL Server Profiler.
Optionally, select the Enable trace stop time check box, and specify a stop date and time.
To add or remove events, data columns or filters, click the Events Selection tab. For more information, see: How to: Specify Events and Data Columns for a Trace File (SQL Server Profiler)
Click Run to start the trace.

In SQL Trace how to see which statement getting more time .

Hi Expart,
In SQL Trace (T-code ST05) . I am running the standard transaction . how to see which statement
running more time and less time . suppose one statement running more time so how resolve the
performance .
Plz. reply me
Regards

No, that is incorrect, the red ones show only the ones which need several hundret milliseconds in one execution. This can even be correct for hard tasks. And there are lots of problem, which you will not see
I have said everything here:
SQL trace:
/people/siegfried.boes/blog/2007/09/05/the-sql-trace-st05-150-quick-and-easy
Go to 'Tracelist' -> Summarize by SQL statements', this is the view which you want to see!
I summarizes all executions of the same statement.
There are even the checks explained, the slow ones are the one which need a lot of time per record!
See MinTime/Rec > 10.000 microseconds.
Check all number of records, executions, buffer, identicals.
The SE30 Tipps and Tricks will not help much.

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.

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

and click on list trace to view the details.
If you notice performance issue, you can perform an SQL trace :
1 - ST05
2 - Activate trace
3 - Run your prog.
4 - Deactivate trace & display it !
You'll see accessed tables, with runtime, etc...
You can also perform traces on other items such as authorisation objects.

Performance Tuning is useful mainly reducing load on database. It is very important aspect while writing the programs/FM etc.....
SQL Trace
Use
The SQL Trace function is an on-demand log of selected SQL statements that are issued against the database through the Open SQL Engine. The SQL Trace can be switched on or off dynamically. The log format is database independent. Besides the SQL statement text, each log record contains information about the point in time when the statement was executed, its duration, its input parameters and results (where applicable) as well as context information.
Features
The SQL Trace is especially useful for:
Development:
SQL Trace can help JDO, enterprise beans, servlet and JSP developers to learn which kind of database accesses their code produces.
 Performance analysis
Typically, performance issues are caused by inefficient database accesses. In this case SQL Trace can be used to show the issued SQL statements and their duration, thus helping to identify inefficient SQL statements.
Functions
The following functions are available on the initial screen:
Select trace:
Select the trace mode SQL Trace, Enqueue Trace, RFC Trace, or Table Buffer Trace. You can select mutliple trace modes simultaneously.
Select trace function:
Start the trace recording.
Stop the trace recording.
Branch to trace list, detailed list, or time-sorted list.
Branch to Explain SQL to analyze an SQL statement without an explicit trace file.
Trace files are managed by the system. Thus they can be saved, like any other object;
saved trace files can be displayed and deleted.
Trace Status
A trace can only be activated once on any application server. The Trace Status display informs you whether another user in the system has already activated a particular trace.
Starting the Trace
Prerequisites
You can only switch on the Performance Trace for a single instance. You should already have decided the scope and targets of your performance analysis.
Procedure
To analyze a trace file, do the following:
... 1. Choose the menu path Test  Performance Trace in the ABAP Workbench.
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.
2. Using the selection buttons provided, set which trace functions you wish to have switched on (SWL trace, enqueue trace, RFC trace, table buffer trace).
3. 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.
4. Now run the program to be analyzed.
You will normally analyze the performance trace file immediately. In this case, it is a good idea to use a separate session to start, stop, and analyze the Performance Trace
If you are shown trace kernel errors on the initial screen (for example, not enough storage space available), you must first remove the errors or have them removed by your system administrator.
The selected trace types can be changed as required during a performance trace interval (time between switching on and off the trace). The user (user group) must remain unchanged.
Result
The results of the trace recording are written to a trace file. If trace records are overwritten during the trace interval, the system displays a message to inform you when you analyze the trace file.
The results of the trace recording are stored to ten trace files. Overwriting trace records, however, cannot be entirely excluded in this case either.
The Performance Trace records all database access calls, table buffer calls, remote calls, or calls for user lock activity. These measurements can affect the performance of the application server where the trace is running. To preserve system performance, you should therefore turn off the trace as soon as you finish recording your application.
Stopping the Trace
Prerequisites
You have started the trace and finished running the program that you want to analyze.
For performance reasons, you should switch off the traces as soon as you have finished recording.
Procedure
To deactivate the trace:
... 1. 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.
2. Select the trace functions that you want to switch off.
3. 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-
Result
The results of the trace are stored in one or more trace files. You can then analyze the performance data stored in the trace file. See also, Analyzing Performance Data.

No insert Statements for EKKO EKPO in ST05 sql trace for transaction me21n

No insert Statements for EKKO EKPO in ST05 sql trace for transaction me21n.
IN ST05 I set a filter for ME21N and executed transaction to create a Purchase Order and then checked
ST05 but there is NO insert for EKKO or EKPO??
How Do I find in which columns of EKKO and EKPO data is inserted in ST05?
Edited by: DeepakNandikanti on Apr 28, 2010 8:27 AM

Hi,
I tried in my system and I can see INSERT statement on EKKO and EKPO tables. What exactly you are looking for? Some one else might have switched on the trace at the same time. Can you try again and see.
ST05=>Switch on trace
ME21N=>Create PO.
ST05=>Switch off and display trace.
In trace list search for EKKO and EKPO.
Column names are not shown in the trace list. It is the SQL trace and column list is generated dynamically like :A0, :A1....
@ Suhas,
That might be because the tables are updated via BAPIs ... Do you think SAP uses direct update statements on the DB tables ??
I didn't get above statement. Is there any other way of updation that happens when using BAPI? I believe that, even in case of BAPI there will be update task FMs called during database update. Please correct if i got it wrong.
Thanks,
Vinod.

Starting SQL-Trace Automatically - Transaction Code: ST05

Good Morning Experts!
I have got a problem with my "SAP - Business Warehouse (BW) System".
We have very much Traffic on this System every night (between 03:00 and 04:00 a.m.).
Because nobody is at work so early in the morning, I wanted to ask you, if there is a possibility to start the SQL-Trace (which you can call by transaction code: ST05) automatically.....?
Is there a possibility to write a short ABAP Code to start the SQL-Trace automatically?
Thank's and best regards.

Hello Rob.
Thank you for replying.
I tried to create a job with the "Job Wizard" with SM36.
Now i realized, that i have to wirte my own ABAP-Report (Programme), which uses the ST05 SQL-Trace function.
I am not an ABAP-Professional, so would you be so kind and give me the code-lines of this programme?
I can not imagine if you have to write only 5-10 lines or if the code is much longer...
Thank you and best 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.

ECAT
eCATT stands for extended Computer Aided Test Tool (eCATT) which is built is testing tool to test SAP system. By using testing tool we can test the entire business process, and we can also use this tool with a third party testing tool (I am not covering this topic). Execution of every test script ends with a log, which explains the results of the test script.
By using eCATT we can do following operations,
·        Test transactions, reports, and scenarios
·        Call BAPIs and function modules
·        Test remote systems
·        Check authorizations (user profiles)
·        Test updates (database, applications, GUI)
·        Test the effect of changes to customizing settings
·        Check system messages

To develop a test script in eCATT we need to follow the following steps,
1. Creating Test Scripts.
2. Creating Test Data Containers[16] .
3. Understanding System Data Containers[17] .
4. Executing Test Configurations.
There is a very good web blog on eCATT in sdn.com which explains eCATT with necessary screen shots.
