Hi Forstmann,
Many thanks for the information.But I require Performance Testing plan materials wher it has been performed in existing systems.
The material link what you have pasted refers to Performance tuning guide.

Performance test planning: timing
Hi folks,
I'm wondering if anyone has suggestions or input on the timing of test planning specific to performance testing. In particular, how far in advance is it recommended that performance test planning would begin in reference to the intended test window(s)Hi Jack,
My preference is to start planning for a performance test as soon as possible, even before there is an application to test.
The first stage in planning should be an analysis of how the application will be used. This information can be gathered from a business plan if the application is new, or from site usage metrics from tools like Omniture or Web Trends if the application is presently deployed.
From the business plan or metrics you can begin to work out the key transactions (most heavily used and most business critical), as well as planning how users will execute those transaction (what percentages, what think times, etc).
Then as the test date gets closer and the application becomes available/stable/etc you can begin to flesh out the details of the plan. But the overall goals, analysis and high level planning can begin very early in the development cycle.

Oracle database Performance testing
What are the procedure to dp Oracle performance Testing???
Is there any tools to do Oracle database Performance or load testing??insa wrote:
OS- windows
DB-Oracle11gr2
Just i want check if 100 of users using my Application at a time what will be the performance of my database??Database performance is dependent on a number of factors - where application design, application code and data model, are critical components.
And these components need to be designed, written, and implemented with performance and scalability as primary requirements. From design issues like using 3NF correctly, to coding issues like using bind variables correctly.
You cannot simply slap design and code together, run that against the database, and then tune database performance. That is not the correct approach. Oracle database technology performs very well. It is the application that does not perform. It is the design that does not perform. It is the architecture that does not perform.
When I see the comment that someone wants to test database performance, I see someone not understanding what determines performance - and incorrectly thinking that the database is a black box, and that this black box's performance can be tuned and set, irrespective of the data model, application code and architecture used. -
Database Performance Testing Tool
Hi Gurus,
Can anyone suggest me some Performance Testing Tools with respect to Database Environment?
The Tools in the Open Source Environment would be preferable.
Thanks in advance.
~AnupHi Anup,
There's a tool called Orion in OTN page that's used to simulate database activity I/O. Try it!

Testbed data for J2EE/database performance testing
Hi all,
I am doing some research into how various databases operate when used in a
J2EE environment - and specifically how the
database implementations affect J2EE performance in the long run. I am
setting up a test environment
with Oracle, Sybase, DB2, SQLServer and mySQL. What I am in search of,
however, is a set of substantial dummy
data that I can use to populate these databases. Does anyone have any
suggestions on how to go about
generating or snagging data which might servce the purpose? Any assistance
is greatly and wonderfully appreciated!
Chana CamposWell.... while you're creating a bunch of application code that does select, update
and delete to your databases - make some that does 'insert'.

CO88-Error :Perform the planned price change for material
Hi Experts,
While running CO88 i get this error. "Perform the planned price change for material ". My material is manage at S and it doesn't have any marked cost. The status is FR and no other status on cost etimate for the article are active. what i shoul do? why if i run the PP order with KO88 i don't have any error?
Please help i'm facing the closing period.Hi,
If dynamic price change is active in your system the first posting in the new period of this material tries to
- release a future cost estimate of that period OR
- change the price to the future price in accounting view
(if the future price date is reached)
Unfortunately this dynamic price change does not work in order settlement. Therefore you are asked to perform the price change first by t-code CKME (or CK24).
If you are using price determination control 3, any price change or release should always be the first transaction in a new period to avoid any inconsistencies.
The dynamic price release will only release the price with transactions which involve material movement and this is not the case by posting invoices and order settlements.
if you are in period 12/2009 then a settlement in 12/2009 does not require the release cost estimate of 01/2010.
But if you are already in 01/2010 therefore settlement in 12/2009 is a posting into the previous period. This will change also data of the current period. Therefore the cost estimate has to be released first.
Another option, if you don't want to receive this message, would be to change this message from Error to Warning (check note 434752).
Please follow the following steps:
T-CD:OMRM
Message M8 394
=>you set the message type to '-' for error message M8394, that means no message is to be issued.

How to setup the environment for doing the Performance Testing?
Hi,
We are planning to start the performance testing for iProcurement Product, Max number of user we are going to use 1000. For this simulation, what are all basic setups need to do for Application Tier, Database Tier,etc... Can anyone suggest what is procedure to setup environment depending upon the load?User Guides for thee rv120W are here:

ALE distribution of planned material changes made using MM12
Greetings,
I have searched and come up empty-handed looking for an answer, perhaps someone in this forum can point me in the right direction. I am trying to find out if there is a tcode and idoc message type that will distribute a planned material change, prior to it's activation, while it is still in it's planned state. While in the source system, I can see these changes in mm14, I do not see the "future" values as part of the MATMAS generated by a BD10, nor as part of the ECMMAS generated by a CC92 transaction. Ideally we could allow material master changes in our source system on a future date using the same ECM number as a BOM change for example, and distribute these changes together to the target system, prior to the ECM effectivity, without further requiring a additional BD10 to be performed after the material change activation date. Does anyone have advice on this? Thank you for any info you can provide.1. Activate change pointers
2. Customize it to check for status before activation and trigger the distribution. (I think it should generate even if the material is not activated so no customization required - but just test and confirm. It's been a while I've looked at this).
3. Maintain this in your distribution model and distribute master data accordingly. -
RMS performance testing using HP Loadrunner
Hi,
We are currently planning on how to do our performance testing of Oracle Retail. We are planning to use HP Loadrunner and use different virtual users for Java, GUI, webservices and database requests. Have anyone here done performance testing in RMS using HP Loadrunner and what kind of setup did you use?
Any tips would be greatly appreciated.
Best regards,
GustavHi Gustav
How is your performance testing of Oracle Retail ? Did you get good results ?
I need to start a RMS/RPM performance testing project and I would like to know how to implement an appropriated structure . Any informations about servers , protocols , tools used to simulate a real production environment would be very appreciated.
Thanks & Regards,

Hi,
Can someone give me an idea of database load testing. Suppose testers are performing load testing on any application & we have to check load (bottlenecks) on database side, then what are the areas we might need to observe from database side.
Oracle version - 10.2.0.3
Thanks in advanceCheck if the server is ok with memmory and cpu usage and swap..........
ON database side check the long running active sessions where they are waiting and suggest something so that these queries can speed up. You can suggest code change like new indexes , hints or outlines etc.....after checking the waits and sql plans of various slow sql statemenets -
Performance testing of servlets / beans / jsp ?
Hi. I'd like to performance test my applications, anyone have a clue on what software to use?
I use Fort� for Java CE 3 as the IDE and TomCat 3.23 as the servlet / jsp container.
Hopefully there are some opensource tools to use for this?
Regards,
ChrisYou can precompile JSP's, this removes the small hickup when they are requested the first time (making the server translate and compile them). Check the documentation of your specific web/application server on how to do this.
Otherwise:
- buy better hardware
- use a better application server
- make sure your network is properly configured (so packets don't get routed around the network four times before they reach their destination for example)
- make sure your program logic doesn't create bottlenecks such as
unnecessary HTTP requests, redundant loops, etc.
- optimize your database access, use connection pooling
- optimize your database queries. Create indexes, make sure the SQL queries themselves aren't doing unnecessary trips around the database, etc. -

How to create a test plan with specific transactions (or program)
Hello,
I'm a new user in Sol Man !
How to create a test plan with specific transactions (or program).
In my Business Blueprint (SOLAR01) I've created in 'transaction tab' the name of my specific transactions and linked it.
In my test plan (STWB_2) those specific doesn't appear to be selected !
Thanks in advance.
Georges HUYNENHi
In solar01 you have defined but you have to assign the test case in solar02 for this test case in the test cases tab.
When you do so expand the business sceanario node in test plan generation of STWB_2 transaction and now that will appear.

Unable to saver images in a note within a Test Plan - STWB_2
Hi all,
While trying to edit a note in Tx STWB_2 (Test Plans), I'm not able to save an image on it. I can add and save text but no images. Other odd thing is that even when I click on "Save Active", the message "Document saved as raw version" appears. In case of text, the data is saved (as mentioned earlier). No mutter save mode I select the note is always saved as a raw.
Is this behavior the standard one or should I perform some actions? Could this message be linked to the fact that I canu2019t saved images in my notes.
Your help is highly appreciated
