Urgent - Performance tuning
The following code takes more execution time..How can we reduce the execution time through performance tuning..
SELECT DISTINCT bebeln AS bktxt bebelp amblnr avgart bbwart bmatnr bwerks blifnr bmenge bebeln b~erfmg
INTO CORRESPONDING FIELDS OF TABLE it_mseg
FROM mkpf AS a INNER JOIN mseg AS b ON bmblnr = amblnr
FOR ALL ENTRIES IN it_ekpo
WHERE
bebeln = it_ekpo-ebeln AND bebelp = it_ekpo-ebelp AND b~matnr = it_ekpo-matnr
Hi!
Either you go for index M of table MSEG.
Then specifiy in addition
b~MATNR eq it_ekpo-matnr
b~WERKS eq it_ekpo-werks
b~LGORT eq it_ekpo-lgort
b~BWART eq '101'
b~SOBKZ eq space
b~ebeln eq it_ekpo-ebeln
b~ebelp eq it_ekpo-ebelp.
Check, if movement type and special stock type are correct in your case. Maybe you need multiple entries, try if this can still speed up the select.
Or you go for document index EKBE.
Start selection the POs. Then select EKBE for all entries with VGABE = '1'. Then go for MKPF/MSEG with primary key. Every table starting from EKBE will have a (partial) primary key access, has to be pretty fast.

Christian

Hi,
Please can anybody help me in the performance tuning of the VA01 transaction since its consuming a lot of time in production.
This issue is very urgent.
Pls help.Always check the driver internal tables is not empty, while using FOR ALL ENTRIES
Avoid for all entries in JOINS
Try to avoid joins and use FOR ALL ENTRIES.
Try to restrict the joins to 1 level only ie only for tables
Avoid using Select *.
Avoid having multiple Selects from the same table in the same object.
Try to minimize the number of variables to save memory.
The sequence of fields in 'where clause' must be as per primary/secondary index ( if any)
Avoid creation of index as far as possible
Avoid operators like <>, > , < & like % in where clause conditions
Avoid select/select single statements in loops.
Try to use 'binary search' in READ internal table. Ensure table is sorted before using BINARY SEARCH.
Avoid using aggregate functions (SUM, MAX etc) in selects ( GROUP BY , HAVING,)
Avoid using ORDER BY in selects
Avoid Nested Selects
Avoid Nested Loops of Internal Tables
Try to use FIELD SYMBOLS.
Try to avoid into Corresponding Fields of
Avoid using Select Distinct, Use DELETE ADJACENT

Report running for long time & performance tuning
Hi All,
(1). WebI report is running for long time.so what are the steps i need to check for it ?
(2). Can you tell me about performance tuning in BO ?
please help me.....
Thanks
Kumar(1). WebI report is running for long time.so what are the steps i need to check for it ?
The first step is to see if the problem lies in the query on the data source or in webi itself. Depending on the data source there are different ways to extract the query and try to run it against the database. Which source does your report uses?
(2). Can you tell me about performance tuning in BO ?
I would recommend to start by reading the administrator's guide. There is a section about how to improve performance.

Oracle 11g Performance tuning approach ?
Hello Experts,
Is it the right forum to follow oracle performance tuning discussions ? If not, let me know what will be the forum to pick up some thread on this subject.
I am looking for performance tuning approach for oracle 11g. I learned there are some new items in 11g in this regard. For persons, who did tuning in earlier versions of Oracle,
what will be the best way adopt to 11 g?
I reviewed the 11g performance tuning guide, but I am looking for some white papers/blogs with case studies and practical approaches. I hope that you have used them.
What are the other sources to pick up some discussions?
Do you mind, share your thoughts?
Thanks in advance.
RIThe best sources of information on performance tuning are:
1. Jonathan Lewis: http://jonathanlewis.wordpress.com/all-postings/
2. Christian Antognini: http://www.antognini.ch/
3. Tanel Poder: http://blog.tanelpoder.com/

5. Cary Millsap: http://carymillsap.blogspot.com/
and a few dozen others whose blogs you will find cross-referenced in those above. -
Performance tuning of BPEL processes in SOA Suite 11g
Hi,
We are working with a customer for performance tuning of SOA Suite 11g, one of the areas is to tune the BPEL processes. I am new to this and started out with stress testing Hello World process using SOAPUI tool. I would like help with the below topics -
1. How do I interpret the statistics collected during stress testing? Do we have any benchmark set that can indicate that the performance is ok.
2. Do we need to run stress tests for every BPEL process deployed?
2. Is there any performance tuning strategy documentation available? Or can anybody share his/her experiences to guide me?
Thanks in advance!
Sritama1. How do I interpret the statistics collected during stress testing? Do we have any benchmark set that can indicate that the performance is ok.
You need
pay attention to:
java heap usage vs java heap capacity
java eden usage vs java eden capacity
JDBC pool initial connections vs JDBC pool capacity connections
if you are using linux: top
if you are using aix: topas
2. Do we need to run stress tests for every BPEL process deployed?
yes, you need test each BPEL. You can use "Jmeter" tool.
Download Jmeter from here: Apache JMeter - Apache JMeter&trade;
Other tools:
jstat
jstack
jps -v
Enterprise Manager
WebLogic Console
VisualVM
JRockit Mission Control
3. Is there any performance tuning strategy documentation available? Or can anybody share his/her experiences to guide me?
I recommend "Oracle SOA Suite 11g Performance Tuning Cookbook" http://www.amazon.com/Oracle-Suite-Performance-Tuning-Cookbook/dp/1849688842/ref=sr_1_1?ie=UTF8&qid=1378482031&sr=8-1&keywords=oracle+soa+suite+11g+performance+tuning+cookbook -

[ADF-11.1.2] Proof of view performance tuning in oracle adf
Hello,
Take an example of : http://www.gebs.ro/blog/oracle/adf-view-object-performance-tuning-analysis/
It tells me perfectly how to tune VO to achieve performance, but how to see it working ?
For example: I Set Fetch size of 25, 'in Batch of' set to 1 or 26 I see following SQL Statement in Log
[1028] SELECT Company.COMPANY_ID, Company.CREATED_DATE, Company.CREATED_BY, Company.LAST_MODIFY_DATE, Company.LAST_MODIFY_BY, Company.NAME FROM COMPANY Companyas if it is fetching all the records from table at a time no matter what's the size of Batch. If I am seeing 50 records on UI at a time, then I would expect at least 2 SELECT statement fetching 26 records by each statement if I set Batch Size to 26... OR at least 50 SELECT statement for Batch size set to '1'.
Please tell me how to see view performance tuning working ? How one can say that setting batch size = '1' is bad for performance?Anandsagar,
why don't you just read up on http://download.oracle.com/docs/cd/E21764_01/core.1111/e10108/adf.htm#CIHHGADG
there are more factors influencing performance than just query. Btw, indexing your queries also helps to tune performance

I am working on already existing PL/SQL code which is written by someone else on validation and conversion of data from a temporary table to base table. It usually has 3.5 million rows. and the procedure takes arount 2.5 - 3 hrs to complete.
Can I enhance the PL/SQL code for better performance ? or, is this OK to take so long to process these many rows?
Thanks!
YoginiCan I enhance the PL/SQL code for better performance ? Probably you can enhance it.
or, is this OK to take so long to process these many rows? It should take a few minutes, not several hours.
But please provide some more details like your database version etc.
I suggest to TRACE the session that executes the PL/SQL code, with WAIT events, so you'll see where and on what time is spent, you'll identify your 'problem statements very quickly' (after you or your DBA have TKPROF'ed the trace file).
SQL> alter session set events '10046 trace name context forever, level 12';
SQL> execute your PL/SQL code here
SQL> exitWill give you a .trc file in your udump directory on the server.

Also this informative thread can give you more ideas:

as well as doing a search on 10046 at AskTom, http://asktom.oracle.com will give you more examples.

Performance tuning in XI, (SAP Note 857530 )
Could any one pls tell me where to find sap notes.
I am looking for "SAP Note 857530 "
Integration process performance(in sap XI).
or how can I view the performance of the integration process ? or exactly how performance tuning is done.
pls help,
Best regards,
verma.Hi,
SAP Note:
Symptom
Performance bottlenecks when executing integration processes.
Other terms
ccBPM
BPE
Performance
Integration Processes
Solution
This note refers to all notes that are concerned with improving the performance of the ccBPM runtime.
This note will be continually updated as improvements are made.
Also read the document "Checklist: Making Correct Use of Integration Processes" in the SAP Library documentation, on SAP Service Marketplace, and in SDN; it contains information about performance issues to bear in mind when you model integration processes.
Refer to the appended notes and maintain the default code changes by using SNOTE, or by importing the relevant service packs. Note that some performance improvements cannot be implemented by using SNOTE and are instead only available in service packs.
Regards
