Performance Tuning on Queues

Hello all!
Does anyone have good documentation on tuning performance for message queues. We are processing a lot of messages, and would like to take advantage of the queues in XI to help the performance. Does anyone know anything about this?

You can use the queues for prioritisation of messages that may help with performance.
Large messages through high priority queues etc.... Provider faster processing and more resoruces. Smaller messages through less urgent queues and slower processing.

Performance tuning in EP6 SP14

Hi,
We just migrated our development EP5 SP6 portal to NW04 EP6 SP14 and are seeing some performance problems with a limited number of users (about 3).
Please point me to some good clear documentation related to performance tuning. Better yet, please tell me some things you have done in your EP6 portal to improve performance.
Any help is greatly appreciated.
Regards,
Rick

Hi
In general we have experienced that NW04 is faster than earlier versions.
One of the big questions is if the response time is SERVER time (used for processing on the J2EE server), NETWORK time (latency and many roundtrips), CLIENT time (rendering, virus-scanning etc) or a combination.
1) Is the capacity on the server ok? CPU utilization and queue lenght high? Memory swapping?
2) A quick optimazation server-side is logging: Plese verify that that log and trace levels are ERROR /FATAL or NONE on J2EE and also avoid logging on IIS and IIS proxy is used
3) Using a HTTP trace you can see if the NW portal for some reason generetes more roundtrips (more GETS) that the old portal for the same content - what is the network latency? Try to do a "ping <server>" from a client pc and see the time (latency) - if it is below 20 ms the network should do a big difference.
4) On the client try to call the portal with anti-virus de-activated if the delta/difference in response times are HUGE your client could be to old? (don't underestimate the client). Maybee the compression should be set different to avoid compres (server) and uncompres (client) - this is a tradeoff with network latency however.
Also client-side caching (in browser) is important.
These are just QUICK point to consider - tuning is complex

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.

Business Process Performance Tuning

Hi Pals,
I would like to request your help and inputs regarding tuning performance of Business process for my scenario.
I have created a synchronous Process with 3 message mapping transformation steps. ( inbetween Sync Receive and Sync Send steps). So its pretty simple process.
I am able to execute only 3500 processes per hour.
The SAP Netweaver Server m/c configuration is 2 dual core processors with 12 GB RAM.
Business process - Without buffering with multiple queues (content specific).
IE Logging - No sync logging, logging level - 0 ( so logging turned off )
I have tried out all the configurations mentioned in below weblogs, but with very less improvement in my case.
Performance Tuning Checks in SAP Exchange Infrastructure(XI): Part-III
Performance Tuning Checks in SAP Exchange Infrastructure(XI): Part-II
Performance Tuning Checks in SAP Exchange Infrastructure
I think something else is choking the execution, as the CPU or memory usage is not more than 10-20%.
Please pour in your inputs.
Thank you!
Best Regards,
Saravanan N

Thank you very much Bhavesh!
In my BPM, all the steps are set for "No New Transaction". So as to avoid any performance issue. But there is no improvement.
Even I have deleted all the work-items from Trxn: SWWL before the test.
From ST03N, for each process instance executed, four function modules takes the maximum time.
Function Module--No. of Calls--
Execution Time/RFC Call
TRFC_QIN_DEST_SHIP-- 1--
995 milliseconds
TRFC_QIN_ACTIVATE--1--
1077 milliseconds
ARFC_DEST_SHIP--2--
280 milliseconds
ARFC_RUN_NOWAIT--2--
402 milliseconds

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.

Stratos

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.

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!
Sritama

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.
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

Performance tuning in PL/SQL code

Hi,
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!
Yogini

Can 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:
HOW TO: Post a SQL statement tuning request - template posting
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.
