Performance / Stress Testing E-Recruitment

Hi Experts,
I am curious if anyone has found a way to accurately stress test external candidate (or internal candidate) scenarios for e-recruitment. The tools we have used in the past have proven misleading, as they have suggested our environment would handle the load, only to find out after implementation that the system could not.
Any ideas/suggestions are greatly appreciated.
Shane

Hi Shane,
A tool like loadrunner works really well. If you used a similar tool but did not get expected results it may just be more of design / setup of your load test.
The key to the load test is to simulate it as much as possible as production scenario.
Your QA load system should have production like data. your test scripts being executed by the tool should simulate as close as possible to real user activity (like putting wait times between steps in the script, doing activities that update and create data, not just perform searches).
Putting other types of loads on the system - erecruitment never works in a vacuum in production, other users are using HR, potentially finance, etc... So other scripts should be loading the system (dialog users, background users) as "control" load, while your "variable" load - erecuritment is running.
just ideas...

XI/PI performance/stress test report

Dear friends,
Does anybody have the XI performance/stress test report or the template for the reference? I need to write a report, but currently still don't have any idea about the content in this document.
Thanks so much for every kind help.

Sorry guys, but I mean a document and not SAP transactions

Performance (Stress Testing) Simulation For Requests

Hi GRC Gurus,
I am looking for a solution for performing a stress test (for performance) for change requests in Access Control. This should be a repeatable process in order to ascertain if there are any bottlenecks in the processing, memmory etc. In normal SAP, e-CATT was one of the simpler solutions - how about GRC Access Control ?
regards
Mushtaq Mahmood

Only one suggestion from experience (due to the multi-fold use of GRC AC).
Try to get 10 volunteers to aggressively submit and approve access requests, perform risk analysis and perform firefighter sessions, i.e. get a through User Acceptance Test performed to get a "as-real" feel of the performance-stress on the system.
At my current client, we have got around 10 volunteers each in the Europe, Americas and Asia offices and UAT is being performed over a 2 weeks cycle to really hammer the system, both to ensure the configuration is correct and working as expected and also to monitor the performance of the system over the global company network.
Basis team are monitoring the performance of the processes and DB usage.

Database base storage stress test

Hi,
I have a ucm 11g instance up and running with SSO.
I need to test database storage against filesystem storage.
Does anyone have any suggestions on how to test this?
Also I'm sure I read somewhere (but I can't find it now) that once I go in one direction I can't go back, does anyone have any details about this?
Many thanks
James

First of all, take a look at File Store Provider (here: http://download.oracle.com/docs/cd/E14571_01/doc.1111/e10792/c02_settings005.htm#CSMSP445)
In general, filesystem storage is always used even if you store data in the database, in the end. It is, though, understood as a temporary storage. In theory, you can keep your files in both locations and I see no reason why you should not be able to go from FS to DB and back, BUT you have to consider consequences (you might have to rebuild indexes or even migrate data from one storage to the other).
As for stress tests, first you have to decide WHAT you want to test. Potential candidates are:
- checkin of a single item (wasted effort: since FS is always used as an intermediate storage it will always be a bit faster)
- mass checkin (e.g. from Batch Loader - especially if you use Fast Checkin settings, db can be a bit faster, but you will need a real lot of small files)
- search
- update (metadata - wasted effort: should be the same)
- backup
- migration of content
Then, you will have to setup two environments with more-or-less the same conditions (CPU power, memory, disk speed).
And finally, you will have to create and run you test cases. I'd suggest to automate stress tests via writing a program calling the same services with the same data. Use WebServices (if non-Java) or RIDC (if Java).
Alternatively, if your task is "to get results" rather than "perform stress tests", you could try to approach consulting services or project managers to provide some normalized results for you. Something can be obtained in this whitepaper: http://www.oracle.com/us/products/middleware/content-management/ecm-extreme-performance-wp-077977.pdf

Stress Test Oracle 9i

Hello,
I want to perform stress tests on my Oracle 9i database. Is there a software that you can recommend to use. Maybe even scripts or shareware. Thank you.

There are a variety of third party load test tools available, generally part of a suite of QA tools. You can also build your own test harnass.
99% of the work, however, is in figuring out what to run to put a representative stress on your application and, thus, your database. Figure out a representative number of OLTP users, a representative number of DSS users, an appropriate overlap in time and in data, etc.

Tools for stress testing

Does any one have any idea if there are any oracle tools to perform stress test on App Server for a given application.

There are tools to perform the performance analysis of BPC, one is loadrunner. But be careful when defining the "hundreds of users using the application simultaneously"; There are many scenarios in my mind, where you could have several hundred users using BPC, but not sending or retrieving data at the exact same time. You might check the SAP sit eto see if any presentations are posted from the Sapphire conference this Spring.
Hope this helps.

ApplicationException during Stress Testing

Hi All,
I have a PAR file(dynpage application) which is deployed in QA portal. The client did stress testing i.e multiple users are trying to access the application at the same time, clicking on various buttons. Sometimes they are getting
'com.sap.xxx.xxx.ApplicationException.'
I did complete testing at my end. The same application is working fine in DEV portal. I do not have access to QA portal. Also, I could not perform stress testing in DEV portal.
But I understand that the problem is not with the coding.
What could be the issue? Please suggest. Hope I am clear. If not, please let me know.
Thanks.

Labview Realtime stress test

Hi,
I need some help.how to perform Labview Real time application level stress test?is there any tookit available?
So far I know I can use DSM to check CPU load and memory usage. Beside from that If I use below screen shot toolkits ,those will give me more on code level and all are each individual VI trace time.
Any Idea how to perform stress test for RT application level .
Thank you.

Stress testing is inherently application dependent. Basically it consists of looking at what your application can do and doing a lot of it.
Say for example, your application lets multiple remote users establish a connection and log some data. An example of a stress test would be to see how many simultaneous connections it can handle without failing or degrading it performance to an unacceptable degree.
What is your realtime application doing?

SAP performance test, stress test using HP LoadRunner

Hi experts,
Our project is going to Go live soon, customer want to ensure about performance of SAP system and require some testing.
I am preparing HP LoadRunner script and perform a most complex scenario for stress test. But with performance test, we cannot perform because we do not have enough transaction data
Please advice me some solution for this case
Thanks & Best Regards,
Luong Doan

Hello,
If you are looking for simulating load using minimalist tools, a crude way to do this would be configuring Ecatt scripts and running them from multiple machines
But I think it doesn't work for web based transactions.

Yes. the code works and the data set gets return when I execute the code. It only fail with stress test after say 150-160 hits.

Hi, T.M.
If you're looking to troubleshoot an intermittent problem that may be hardware-related, See my "Apple Hardware Test" FAQ for comprehensive advice on using the Apple Hardware Test in troubleshooting, including running the test in Loop Mode.
There is also Xbench, a performance benchmarking tool.
More details as to what prompts your question might help.

Stress Test Tool

Dear Experts, I have here installed the Enterprise Portal only in JAVA, NW2004s 7.0.
Our Go-Live is near and I want to know if haves any tool to stress the access to my Portal.
Somebody know any free tool to stress the test that I need to do?
Thanks for all.

Hello Marcos,
we have used the "Web Application Stress Tool" for stress tests:
http://www.microsoft.com/downloads/details.aspx?FamilyID=e2c0585a-062a-439e-a67d-75a89aa36495&displaylang=en
You can record a typical task in your portal and after that you can make a stress test with it.
After your stress test you will get an overview of the response times and performance. If you wish you can go in detail too.
Regards
Stefan

Stress Test on Portal

Hello,
We are on EP7.0 and trying to run the Open Enrollment for Benefits in the month of Nov. ...I want to know whether there is any tool to log in a number of users on the EP at one time to do a Stress test ...
Also, usually how many users logged on the Portal are considered to be performance effective.
Any help would be highly appreciated

Hi,
Have a look at JMeter (open-source) or Mercury LoadRunner (expensive but very powerful)
