Performance Tuning for Concurrent Reports
Hi,
Can you help me with Performance Tuning for Concurrent Reports/Requests ?
It was running fine but suddenly running slow.
Request Name : Participation Process: Compensation program
What is your application release?
Please see if (Performance Issues With Participation Process: Compensation Workbench [ID 389979.1]) is applicable.
To enable trace/debug, please see (FAQ: Common Tracing Techniques within the Oracle Applications 11i/R12 [ID 296559.1] -- 5. How does one enable trace for a concurrent program INCLUDING bind variables and waits?).
Thanks,
Hussein

Performance Tuning for OBIEE Reports
Hi Experts,
I had a requirement for which i have to end up building a snowflakt model in Physical layer i.e. One Dimension table with Three snowflake tables(Materialized views).
The key point is the Dimension table is used in most of the OOTB reports.
so all the reports use other three snowflakes tables in the Join conditions due to which the reports take longer time than ever like 10 mints.
can anyone suggest good performance tuning tips to tune the reports.
i created some indices on Materialized view columns and and on dimension table columns.
i created the Materialized views with cache Enabled and refreshes only once in 24 hours etc
is there anything i have to improve performance or have to consider re-designing the Physical layer without snowflake
Please Provide valuable suggestions and comments
Thank You
KumarKumar,
Most of the Performance Tuning should be done at the Back End , So calculate all the aggregates in the Repository it self and Create a Fast Refresh for MV and you can also do one thing you can schedule an IBOT to run the report every 1 hour or some thing so that the report data will be cached and when the user runs the report the BI Server extracts the data from Cache
Hope that helps

Performance Tuning for a report
Hi,
We have developed a program which updates 2 fields namely Reorder Point and Rounding Value on the MRP1 tab in TCode MM03.
To update the fields, we are using the BAPI BAPI_MATERIAL_SAVEDATA.
The problem is that when we upload the data using a txt file, the program takes a very long time. Recently when we uploaded a file containing 2,00,000 records, it took 27 hours. Below is the main portion of the code (have ommitted the open data set etc). Please help us fine tune this, so that we can upload these 2,00,000 records in 2-3 hours.

Edited by: kishan P on Sep 17, 2010 4:50 PMHi Peter,
I would suggest few changes in your code. Please refer below procedure to optimize the code.
Steps:
Please run SE30 run time analysis and find out if ABAP code or Database fetch is taking time.
Please run extended program check or code inspector to remove any errors and warnings.
Few code changes that i would suggest in your code
For select query from t001w & marc remove the corresponding clause as this also reduces the performance. ( For this you can define an Internal table with only the required fields in the order they are specified in the table and execute a select query to fetch these fields)
Also put an initial check if str_table[] is not initial before you execute the loop.
where ever you have used read table. Please sort these tables and use binary search.
Please clear the work areas after every append statment.
As i dont have a sap system handy. i would also check if my importing parameters for the bapi structure is a table. Incase its a table i would directly pass all the records to this table and then pass it to the bapi. Rather than looping every records and updating it.
Hope this helps to resolve your problem.
Have a nice day
Thanks -

Performance Tuning for BAM 11G
Hi All
Can anyone guide me for any documents or any tips realted to performance tuning for BAM 11G on on LinuxIt would help to know if you have any specific issue. There are number of tweaks all they way from DB to Browser.
Few key things to follow:
1. Make sure you create index on DO. If there are too much old data in the DO and not useful then periodically delete it. Similar to relational database indexes, defining indexes in Oracle BAM creates and maintains an ordered list of data object elements for fast retrieval.
2. Ensure that IE setup to do automatic caching. This will help with reducing server round trips.
3. Tune DB performance. This would typically require DBA. Identify the SQL statements most likely to be causing the waits by looking at
the drilldown Top SQL Statements Ordered by Wait Time. Use SQL Analyze, EXPLAIN PLAN, or the tkprof utility to tune the queries that were identified.
Check the Dataobject tables involved in the query for missing indexes.
4. Use batching (this is on by default for most cases)
5. Fast network
6. Use profilers to look at machine load/cpu usage and distribute components on different boxes if needed.
7. Use better server AND client hardware. BAM dashboard are heavy users of ajax/javascript logic on the client -

HI,
I am getting the error The action cannot be performed error for Webi Report. I am getting this error after i save the report and open it again.This is happening for only 1 particular report. In the end i removed some of the objects from the query and added some new ones.
Strangely it worked! -

Edited by: jaya rangwani on May 11, 2010 12:52 PMHello Jaya,
Will provide some point which will increase the performance of the program:
1. VBAK & VBAP are header & item table. And so the relation will be 1 to many. In this case, you can use inner join instead multiple select statement.
2. If you are very much confident in handling the inner join, then you can do a single statement to get the data from VBAK, VBAP & VBKD using the inner join.
3. Before using for all entries, check whether the internal table is not initial.
And sort the internal table and delete adjacent duplicates.
4. Sort all the resultant internal table based on the required key fields and read always using the binary search.
You will get a number of documents where you can get a fair idea of what should be done and what should not be while doing a program related to performance issue.
Also you can have number of function module and BAPI where you can get the sales order details. You can try with u2018BAPISDORDER_GETDETAILEDLISTu2019.

Performance Tuning of webi report BO4.0
Hi ,
I have report which has two data providers in 1st Data Provider i have 10 objects and in 2nd Data provider i have 3 objects the issue is performance report is taking 6 minutes to run.
Please help me out how we can increase the performance at Query Level.
Thanks
SivaHi
There are various levels to which you have to check to improve the performance of reports could be at connection levels, query, database etc.
some of them you can try
1. check array fetch size in relational connection parameters, deactivating array fetch size can increase the efficiency of retrieving your data, but slows server performance.
2. Setting options for the default list of values in business layer and data foundation layer
Automatic refresh - If this is selected, the list of values is automatically refreshed each time the
list is called. This can have an effect on performance each time the list of values is refreshed. You should disable this option if the list of values returns a large number of values.
3. set query stripping (Optimize query with Query Stripping in Web Intelligence - Business Intelligence (BusinessObjects) - SCN Wiki)
4. also check Performance Tuning Methods in BO

Need help in Performance tuning for function...
Hi all,
I am using the below algorithm for calculating the Luhn Alogorithm to calculate the 15th luhn digit for an IMEI (Phone Sim Card).
But the below function is taking about 6 min for 5 million records. I had 170 million records in a table want to calculate the luhn digit for all of them which might take up to 4-5 hours.Please help me performance tuning (better way or better logic for luhn calculation) to the below function.
A wikipedia link is provided for the luhn algorithm below
Create or Replace FUNCTION AddLuhnToIMEI (LuhnPrimitive VARCHAR2)
RETURN VARCHAR2
AS
Index_no NUMBER (2) := LENGTH (LuhnPrimitive);
Multiplier NUMBER (1) := 2;
Total_Sum NUMBER (4) := 0;
Plus NUMBER (2);
ReturnLuhn VARCHAR2 (25);
BEGIN
WHILE Index_no >= 1
LOOP
Plus := Multiplier * (TO_NUMBER (SUBSTR (LuhnPrimitive, Index_no, 1)));
Multiplier := (3 - Multiplier);
Total_Sum := Total_Sum + TO_NUMBER (TRUNC ( (Plus / 10))) + MOD (Plus, 10);
Index_no := Index_no - 1;
END LOOP;
ReturnLuhn := LuhnPrimitive || CASE
WHEN MOD (Total_Sum, 10) = 0 THEN '0'
ELSE TO_CHAR (10 - MOD (Total_Sum, 10))
END;
RETURN ReturnLuhn;
EXCEPTION
WHEN OTHERS
THEN
RETURN (LuhnPrimitive);
END AddLuhnToIMEI;
http://en.wikipedia.org/wiki/Luhn_algorithmAny sort of help is much appreciated....
Thanks
RedeThere is a not needed to_number function in it. TRUNC will already return a number.
Also the MOD function can be avoided at some steps. Since multiplying by 2 will never be higher then 18 you can speed up the calculation with this.
create or replace
FUNCTION AddLuhnToIMEI_fast (LuhnPrimitive VARCHAR2)
RETURN VARCHAR2
AS
Index_no pls_Integer;
Multiplier pls_Integer := 2;
Total_Sum pls_Integer := 0;
Plus pls_Integer;
rest pls_integer;
ReturnLuhn VARCHAR2 (25);
BEGIN
for Index_no in reverse 1..LENGTH (LuhnPrimitive) LOOP
Plus := Multiplier * TO_NUMBER (SUBSTR (LuhnPrimitive, Index_no, 1));
Multiplier := 3 - Multiplier;
if Plus < 10 then
Total_Sum := Total_Sum + Plus ;
else
Total_Sum := Total_Sum + Plus - 9;
end if;
END LOOP;
rest := MOD (Total_Sum, 10);
ReturnLuhn := LuhnPrimitive || CASE WHEN rest = 0 THEN '0' ELSE TO_CHAR (10 - rest) END;
RETURN ReturnLuhn;
END AddLuhnToIMEI_fast;
/My tests gave an improvement for about 40%.
The next step to try could be to use native complilation on this function. This can give an additional big boost.

Performance Tuning for ECC 6.0
Hi All,
I have an ECC 6.0EP 7.0(ABAPJAVA). My system is very slow. I have Oracle 10.2.0.1.
Can you please guide me how to do these steps in the sytem
1) Reorganization should be done at least for the top 10 huge tables
and their indexes
2) Unaccessed data can be taken out by SAP Archiving
3)Apply the relevant corrections for top sap standard objects
4) CBO update statistics must be latest for all SAP and customer objects
I have never done performance tuning and want to do it on this system.
Regards,

Performance tuning for new OFMW environment
Hello
We have just set up a new UAT environment entirely on all Oracle FMW latest products which includes:
1) OS -RHEL V5
2) WebCenter
3) SOA Suite
4) Database
5) IDM
6) HTTP Server
7) WebLogic Server
As as post infrastructure setup plan we need to to performance tuning as well. Shall we do only WLS performance tuning or we need to tune each and every product in order to get optimum results.
Any guide? resource to help?
Pls advice
Regards
DevWhen you install the product soa-suite (and probably webcenter too) a prerequisite check is performed
that gives information about packages and parameters that need to be adjusted on your operating system.
For products that run on WebLogic Server you probably have to tune the JVM, examples can be found here:
- http://middlewaremagic.com/weblogic/?p=6930 (discusses JRockit)
- http://middlewaremagic.com/weblogic/?p=7083 (focuses on Coherence, but the considerations can be applied to other environments as well)
Examples that set-up the SOA-Suite can be found here:
- http://middlewaremagic.com/weblogic/?p=6040 (discusses considerations when installing the SOA suite)
- http://middlewaremagic.com/weblogic/?p=6872 (discusses considerations when adding the web-tier to the SOA suite)
The enterprise deployment guides can help too:
- SOA Suite: http://download.oracle.com/docs/cd/E21764_01/core.1111/e12036/toc.htm
- WebCenter: http://download.oracle.com/docs/cd/E21764_01/core.1111/e12037/toc.htm
These also contain sections on integration with Oracle Identity Management and the Oracle HTTP Server -

Performance tuning of a report.
hello all,
I have been assigned a report to improve the performance.Initially after studying the report i found that all the data was fetched by using select * from... query,hence i changed the query by selectin the particular feilds from the tables.the tables used in my report r bsid and bsad majorly..after these changes there was not much of a diff in the performance,after tracing the report thru st05 it was realized that the select for bsad is taking the max time to fetch..as bsad is a huge table and has huge amount of data..is ther any way i can reduce this time..by using indexes n all..can u please provide me with an example to reduce the time taken for fetchin data from bsid and bsad..
