Performance Tunned Trace/ Analysis tool

Hi,
I am seraching for any tool / utility provided by SAP in the ABAP Development workbench to trace/analyse the perofrmace of DB Accesses , Internal table operations in programs so I could analyse the inefficient ABAP code and could replace the same with efficient.
thanks and regards,
Avakash.

Hi Avakash,
Check this info.
You can use ST05 to find the performance of each select.
u can use SE30 - runtime analysis to find which part of your code is taking more time.
using ST05:
activate the trace --> execute the program --> deactivate the trace --> display trace.
then go to Trace list --> Summarize trace by SQL statements.
here u can analyze performance of all the selects.
If you want to compare the duration by the selects in your program itself then use: GET RUNTIME statement.
Hope this resolves your query.
Reward all the helpful answers.
Regards

Trace Analysis

Where can I obtain the details and "interpretations" of a trace, i.e., what does ringmode=1 mean?; what does CallState=1 mean? Where can I get whatever all the trace headings, messages, etc.??????? If anything, we don't have any CCM plugins, and we don't have Trace Analysis tool configured nor installed on our cluster. Thank you in advance for your assistance.

Though a little old now, there is a book out there written by Paul Giralt which talks in detail about CCM traces. Its titled "Troubleshooting Cisco IP Telephony." This covers CCM 4.x, but the basics of traces haven't changed much since then... just won't include a lot of the newer 5.x and later features. Will do a good job of covering media and call flow however.
ISBN-10: 1587050757
ISBN-13: 978-1587050756
I have been in TAC supporting CUCM for more than 5 years and I still refer to Paul's book from time to time.

Tools in Performance Tunning

What are the tools in performance Tunning in ABAP/4
Thanks Regards,
Kumar

Hi kumar,
Tools provided for Performance Analysis
Following are the different tools provided by SAP for performance analysis of an ABAP object
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 the SPFLI table in our test program is 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.
how to perform sql trace:
Poorly written SQL statements have the greatest impact on application performance. An SQL
statement using which an Oracle database system reads and/or sorts thousands or even millions of
rows of data can bring the database to a standstill. Indexes should be used properly to prevent such
situations from occurring. To analyze such problems you should use the SQL Trace (TCode ST05) to
with database access operations.
CAUTION
Only one person can perform an SQL trace at a time. Remember to turn off the
trace when you are finished. SQL trace slows the system down.
1. Using SQL Trace
1. Open a program that you want to analyze, in the editor, so that it is ready and waiting to be
executed.
2. Open a new session using the menu path System   Create session.
3. Run transaction ST05 (enter /nst05-zero-five, not oh-five in the Command field, or choose
the menu path System Utilities Performance Trace).
4. Then the initial screen of the test tool appears.
The status of the Performance Trace is displayed in the lower part of the screen. This status tells you
three things namely
Whether any of the Performance Traces are switched on
The users for whom Performance Trace is enabled
The user that switched the Performance Trace on
If the trace is switched on you must switch it off before you can proceed. There are two cases in
which the trace needs to be switched off. They are
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.
5. The initial screen has various trace functions such as SQL Trace, Enqueue Trace, RFC
Trace
6. Select SQL Trace.
7. There are various options under which trace can be switched on. They are
If you want to switch on the trace under your user name, choose Trace on.
If you want to switch on the trace for another user or user group, choose Trace on for user.
To enter a single user, specify the user name.
To enter a user group, specify a search pattern (you can use the normal wildcards).
If you want to change the user or user group, switch off the Performance Trace and then restart it,
entering the new users or user group.
8. Now switch back to the window containing your editor session (the one with your program
waiting to be executed).
9. Press F8 to run your program.
Note Just press F8 and do nothing. Do not even press the Back button.
10. When your program has run and the hourglass is no longer displayed, switch back to the trace
window.
11. Press the Trace Off pushbutton.
12. Once Performance Trace is switched off, you can analyze the data
Using Runtime Analysis Tool (SE30)
1. You can open the Runtime Analysis tool as follows:
To start from Choose
Any screen System   Utilities   Runtime Analysis   Execute
Initial screen of ABAP
Workbench
Test   Runtime Analysis
Initial screen of ABAP Editor Program   Execute Runtime Analysis
ABAP Editor Utilities   More utilities   Runtime Analysis
2. In the simplest case, you would enter a short description and a measurement object
(transaction, program, or function module) to run the analysis in the current session.
3. In the Measurement restrictions group box, you can make more specific restrictions for the
measurement. For example, you may want to include only certain statements or time periods.
(For further information refer section 3. 0).
4. To start the measurement, choose Measure runtime. From the initial screen, you can
specify whether the analysis should run in the same session or in a parallel session using the
Enable/Disable button in the In parallel session group box.
5. Run the transaction, program, or function module as normal.
6. Return to the initial screen of the Runtime Analysis transaction. To do so, either leave
transaction, program, or function module as normal, or start the runtime analysis again.
7. The name of the performance data file that has just been created is displayed at the bottom of
the initial screen. The file created by the system is added to the list of performance data files.
You can now analyze, print, or delete the file, or save it locally. The Performance file group
box contains options for analyzing performance files. (For further information refer sections 4.
0 and 5. 0)

Performance Analysis Tools

Hi,
I have a problem with performance analysis tools.
1) I am using java -jar perfviewer.jar to launch the performance viewer.
Using Visual Administrator, I have Exported Configuration data of services to .zip file.
In Performance Viewer, I have used this zip to load the exported values using option Source Files-> Load.
It has thrown an error saying Format of the file was not recognized.
Can any one help me in this??????

Regarding Performance tunning...

HI Experts,
can you suggest me, how exactly performance is checked.
what is the measure we considered for performance check.
what are ideals status of the performance check for a certain program.
that is, how much should be database use, abap use and the system
use in the program.
i checked my program in t-code SE30, and it is showing almost
above 90% use of database and very less use of abap and
almost no use of system.
so please tell me exactly how much it should be...
Thanks in advance.

vijay chavan

Hi
these are the ways of checking performance of a report
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.

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.
Run time analysis transaction SE30
steps
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
Run time analysis transaction SE30
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.
SQL Trace ST05
steps
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.

Urgent : How to do the SQL trace analysis

Hi Floks,
How to do the SQL Trace analysis and any another tools is there to test abap programming then this tools runtime analysis,extended Programming Checking,Code inspector .How to utilize that tools .please forward me

HI,
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.
1. 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.
Activities
Typically, you should use the SQL Trace when you need to check the behavior of a particular application. This is the following scenario:
Look at the below links, you will get the idea

How to do Performance tunning in OBIEE

Hi All,
We are using OBIEE 10.3.4 version on windows envorinment .In our OBIEE project we are using 9 reports my requriment is we need to do performance tunning for OBIEE side.For eace report accessing its taking around 80 sec.We need to decrease these accessing time,is there any possibility to access all the reports with less response time in OBIEE side.
Could you anyone suggest how to do performance tunning in OBIEE side.

This section provides a few examples of how to use Oracle hints in conjunction with the Oracle BI Server. For more information about Oracle hints, refer to the Oracle SQL Reference documentation for the version of the Oracle server that you use.
Index Hint
The Index hint instructs the optimizer to scan a specified index rather than a table. The following hypothetical example explains how you would use the Index hint. You find queries against the ORDER_ITEMS table to be slow. You review the query optimizer's execution plan and find the FAST_INDEX index is not being used. You create an Index hint to force the optimizer to scan the FAST_INDEX index rather than the ORDER_ITEMS table. The syntax for the Index hint is index(table_name, index_name). To add this hint to the repository, navigate to the Administration Tool's Physical Table dialog box and type the following text in the Hint field:
index(ORDER_ITEMS, FAST_INDEX)
Leading Hint
The Leading hint forces the optimizer to build the join order of a query with a specified table. The syntax for the Leading hint is leading(table_name). If you were creating a foreign key join between the Products table and the Sales Fact table and wanted to force the optimizer to begin the join with the Products table, you would navigate to the Administration Tool's Physical Foreign Key dialog box and type the following text in the Hint field:
leading(Products)
So, the table names "order_items" and "products" in the above documentation will not be the same after BIEE puts aliases on them.

Analysis Tool in Reader 9

I am unable to use te measure option in Analysis Tool of Adobe Reader 9. In View / Toolbar / More Tools there is a note saying that I have to activate the Document Rights to enable measuring tool.
It means nothing to me. Anybody can help me?

I have Acrobat Pro Extended (trial version for while) and I can't see the function that perform this operation. In Adobe Forum search I found references to Java, C# and .NET script to do so.
Thank you Aandi anyway.

Source code analysis tools for ActionScript 2?

I have been tasked with performing source code analysis on a very large (>1000 files) AS2 codebase.
Not surprisingly, Googling is not yielding useful results. Before declaring defeat, I felt it important to query this forum.
Any guidance would be appreciated.

We'd like to evaluate the hundreds of files using a static analysis tool, just as one would use lint for a C codebase.
Thanks,
M

Cannot Perform Tune-Up

I am no longer able to perform a health analysis or perform a tune-up. How to fix this?

Hello helpsuze,
Please include what make / model computer you are working with and what operating system it is running.
What happens when you attempt to run the health analysis and perform the tune-up, how does the computer respond?

Performance Tune Stored procedures

Hi Experts,
What is the best approach to performance tune stored procedures. Is it to run expalin plan for the queries used in cursors or there is more to it?
I need all your advise.
Thanks

As generic advice: Absolutely not.
The performance of PL/SQL may be irrelevant to the performance of specific SQL statements contained.
Consider the following:
1. A very inefficient query that runs one time and takes 2 seconds to execute.
2. A query that runs in 2 milliseconds inside a loop.
Which one is more likely to be the issue?
The answer is that it depends on the number of interations of the loop.
The proper tool for tuning PL/SQL, as discussed by Tom Kyte, are, depending on version, DBMS_PROFILER or DBMS_HPROF.
Find out where the time is being spent.
Then tune that which takes the most time.
It is not necessarily the slowest SQL statement.

EP Performance Tunning and concurrent user login problems

Hi all.
We have a EP , integrated with Windows AD and SAP R3.
In real situation, there will be 1000 users login in EP in 0.5 hours. And their operation time will be 6-8 hours, connect to R3 or other applications.
Is EP can support such concurrent user login scenario ?
if EP fails, is there some performance monitor tool or performance tunning issue ?

Hi
EP supports this logon load, however it all depends on sizing and architecture! Also the content of the STARTPAGE can be critical (make it "light").
If the portal fails, then often it is only one J2EE server process, which fails - so by having more server-processes will be an easy/minimum form of high availability. A "real" HA solution must be considered if your business will not work without the portal og SAPGUI connections can be used as workaround/fallback in such situations.
