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 Linux

It 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,
Can you help me with Performance Tuning for Concurrent Reports/Requests ?
It was running fine but suddenly running slow.

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

There 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.

Hello 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 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
Dev

When 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 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
Kumar

Kumar,
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.
select matnr from mara into table t_mara.
select werks from t001w into corresponding fields of table t_t001w .
select matnr werks from marc into corresponding fields of table t_marc.

Hi 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 11g Database

I've heard some Oracle DBA's suggest / recommend that specific parameters be tuned in the O.S. for using Linux as a dedicated Oracle 11g database server. I'm guess those parameters vary greatly based on utilization, hardware, and various other factors. I just wanted to ask if there are some soft or safe performance adjustments I can make which regardless of other various factors that are unknown would most likely benefit and or improve database performance?
Here is what I know:
- OS = RHEL 6.2 or OEL 6.2 64-bit
- RAM = 4 GB
- x2 Quad Core Xeon CPU's
Thanks for shedding any light on this for me...

ALWAYS read and follow the instructions provided by Oracle in the installation guide. It discusses the very issue you mention.
http://docs.oracle.com/cd/E11882_01/install.112/e24321.pdf
There is even a section for 'Configuring Kernel Parameters for Linux'
After you read the installation guide and evaluate your own installation environment if you have any specific questions then post them. And if you intend to 'guess those parameters vary greatly based on utilization, hardware, and various other factors' then it should be obvious that you need to provide information on 'utilization, hardware, and various other factors' or we won't be able to help you with your specific use case.

Performance tuning for ABAP Query (created from t-cd SQ01)

Hello all,
We created ABAP Query report from transaction SQ01.
But the generated report has an appropriate SQL statement which causes performance problem.
To solve this issue, I guess the easiest way is;
0. Give up to use it.
1. Copy it to another object in the customer namespace.
2. Ajust SQL statement.
But I'm wondering if there're appropriate ways to adjust SQL statement of Query.
Could anybody give me any better idea?
Thank you
Yuko

You can try this: Create 2 ranges, for objnr and cdtcode and fill like:
ra_objnr-sign = 'I'.
ra_objnr-option = 'CP'.
ra_objnr-low = 'OR*'.
append ra_objnr.
ra_code-sign = 'I'.
ra_code-option = 'CP'.
ra_code-low = 'CO*'.
append ra_code.
SELECT objnr udate utime
FROM jcds
INTO TABLE it_jcds
WHERE objnr IN ra_objnr
AND stat = l_tj02t
AND cdtcode IN ra_code
AND inact = space

John.
