EJB Performance Test

How do i test MY EJB performance from a Desktop client or JSP or Servlet, I don't have any testing tools

Hi ,
If u don't have any tool as such , then you can try testing your EJBs from more than one macines at least.
I think, the real performance of any distributed components won't be really tested unless and until they are tested for many requests. This is specificaly true with the EJB transactions for dead-locks.
If u don't have any tool , then u can write a program that sends many requests in a loop , for JNDI look-ups .
Hope this helps .

Live discussion on "EJB Performance Verification"

Empirix, the maker of the Bean-test EJB testing tool, is offering a
free one hour web event presentation called "Enterprise JavaBeans
Performance Verification". This event will be held this Friday
November 16th at 2pm EST.
To register for this web event or learn about about web events being
offering by Empirix, go to: http://webevents.empirix.com/Q42001/
Enterprise JavaBeans Performance Verification
Enterprise Java Beans (EJBs) are the central components in a
Java-based enterprise architecture solution. They contain the business
logic for an enterprise system and implement the communication between
the Web-tier and database tiers. EJBs typically are architected and
implemented for months before integrating with the Web-tier hardware
and software. Waiting to verify the scalability of the overall EJB
design and the efficient implementation until late in the software
project with a Web test tool is risky and may cause the entire
software project to fail.
Due to the important role EJBs play, performance testing of the EJB
architecture and implementation is critical during the entire design
cycle, the test cycle, application server tuning, and with any
hardware and software environment changes. Manual vs. automated EJB
component verification strategies will be discussed. During the
presentation, we will show how an example EJB will be scalability
tested using Bean-test, Empirix's automated EJB component test tool.
We will show how Bean-test automatically creates a test harness,
exercises an EJB under load, isolates a scalability problem, and
confirms an implemented correction to the scalability problem is
successful.

Note, there is a replay of this free web event on Monday, December
10th at 2pm EST for those who could not make it the first time.

Looking for a Performance testing tool

We want to stress test our multiserver Adobe Connect before putting into production. HP tool was not successful. Any Recommendations on tool and method?

Cameron,
Thanks for your input! Sounds like you are probably using these
products.
I saw the PerformAssure demo. Their GUI is very slick!! PerformAssure
does some cool stuff like comparing EJB metrics with system metrics
and were able to show me the EJB method that was causing a problem
with a petstore application.
I heard about this new tool from a company called Performant
(http://www.performant.com). I am signed up for a demo with these
folks. Will let you all know what I find.
I looked at Wily site and didn't persue them as they seem to be
deployable in the production environment. Our application is not live
yet, but we want to be able to make sure it can handle good load ;)
Thanks!

I haven't had a chance yet to look at Sitraka's software, but Precise
Indepth/J2EE and Wily Introscope are both pretty popular with Weblogic, and
I think they both do a good job of what they do.

Hello All!
I need help! I am trying to find out which of the tools is better
suited for me to be able to do performance testing of an application
under load.
I am looking for a tool that can provide me detailed application
performance metrics. Seems like both Insight and Perform Assure can do
this job for me.
If any of you have had experience with using performance tools such as
Prescise Insight or Sitraka's Perform Assure I would appreciate any
input you might have on your usage experience of these tools.
Also if you know of any other tools that might provide similar
information such as the above tools, that would be really helpful.
Thanks a bunch!

UI performance testing of pivot table

Hi,
I was wondering if anyone could direct me to a tool that I can use to do performance testing on a pivot table. I am populating a pivot table(declaratively) with a data source of over 100,000 cells and I need to record the browser rendering time of the pivot table using 50 or so parallel threads(requests). I tried running performance tests using JMeter, but that didn't help.
This is what I tried so far with JMeter:
I deployed the application in the integratedweblogicserver and specify the Url to hit in JMeter ( http://127.0.0.1:7101/PivotTableSample-ViewController-context-root/faces/Sample) and added a response assertion for the response code 200. Although I am able to hit the url successfully, the response I get is a javascript with a message that says "This is the loopback script to process the url before the real page loads. It introduces a separate round trip". When I checked in firebug, it looks like request redirect of some sort happens from this javascript to another Url (with some randomly generated parameters) which then returns the html response of the pivot table. I am unable to hit that Url directly as I get a message saying "session expired". It looks like a redirect happens from the first request and then session is created for that request and a redirect occurs.
I am able to check the browser rendering time of the pivot table in firebug (.net tab), but that is only for a single request. I'd appreciate it if anyone could guide me on this.
Thanks
Naveen

I found the link below that explains configuration of JMeter for performance testing of ADF applications(Although I couldn't find a solution to figure out the browser rendering time for parallel threads).

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,
Chris

You 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.

Can Web Performance Test work on AJAX or Javascript Project which will show only one URL for all the pages?

Hi there,
I'm working on testing a AJAX and JavaScript Project which has several pages but all in the same URL. I need to test some attribute on the page or parameter past by AJAX or Javascript. Can Web Performance Test work to get what I want?
Thanks,

Hello,
Thank you for your post.
Web performance test is used to test if a server responses correctly and the response is consistent with what we expected. And we test the response speed, the stability and scalability.
The Web Performance Test Recorder records both AJAX requests and requests that were submitted from JavaScript, but
web test does not execute JavaScript. I am afraid that you can’t use web test to test parameter past by AJAX or JavaScript.
Please see:
Web Performance Test Engine Overview
About JavaScript and ActiveX Controls in Web Performance Tests
From the first link, “Client-side scripting that sets parameter values or results in additional HTTP requests, such as AJAX, does affect the load on the server and might require you to manually modify the Web Performance Test to simulate the scripting.”
If you want to execute the function typically performed by script in web test, you need to accomplish it in coded web performance test or a web performance test plugin. Please see:
How to: Create a Coded Web Performance Test
How to: Create a Web Performance Test Plug-In
I am not sure what the ‘some attribute on the page’ is. If you mean that you want to test those controls on the page, you can do coded UI test, which can test that the user interface for an application functions correctly. The coded UI test performs actions
on the user interface controls for an application and verifies that the correct controls are displayed with the correct values. You can refer to this article for detailed information about code UI test:

Performance Testing - Upgrade from 4.6B to ECC6.0

Hi,
We are doing an upgrade from SAP 4.6B to ECC6.0. I would like to know what would be the best approach for doing a performance test in an upgrade project. More specifically,
1. What are the main components that need to be tested for performance?
2. What are the important transaction codes/external applications (if any) that can be used to do performance testing in both 4.6B and ECC6.0? (ST05 or ST30 or something else?)
3. Any best practice recommended by SAP for doing performance tests?
Thanks in Advance,
Reena

Need to install Visual C++ 2010 in MDT before performance testing.

Hi all,
I'm in a situation in which I'm deploying a laptop over MDT, and the display driver is captured by MDT fine. However, upon initial boot after installing the OS, I come across this error when running WINSAT.exe; "The program can't start because MSVCR100.dll
is missing from your computer. Try reinstalling the program to fix the problem." This isn't the first report I've seen of ATI drivers triggering this, but I'm stuck with it regardless.
This is attributed to a component of Visual C++ 2010 not being installed. (It's not preinstalled in our capture, and I'm trying to avoid having to do that again.)
Being that we're a 0-touch organization when imaging, I need a way to remedy this. I'm currently trying to run the install, 'vcredist_x86.exe /q:a' from "run a command line" (sourced on the server's C:\ drive) before the performance tests,
but I can't find a proper place to put this command at in the task sequence. Is this even a viable method? Is there a method to skip WINSAT.exe pre-boot? My initial tests with this aren't working.
Any advice or pointers appreciated!

Hi,
Normally I think WinSAT is only relevant when deploying the image to your targeted computers (hardware). So why not integrate Visual C++ components into your reference image?
At the customer I'm currently working for we also put all our Visual C++ installations in the so called Build image.
I have provided a list with the install commands for the various programs.

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?

FORMS CRASHES (FRM-92101) ON AS 10.1.2.0.2 DURING LOAD PERFORMANCE TESTING

Hiya
We have been doing Load Performance Testing using testing tool QALoad on our Forms 10g application. After about 56 virtual users(sessions) have logged-in into our application, if a new user tries to log-in into our application, the Forms crashes. As soon as we encounter the FRM-92101 error, no more new forms session are able to start.
The Load Testing software start up each process very quickly, about every 10 seconds.
The very first form that appears is the login form of our application. So before the login screen appears, we get FRM-92101 error message.
However, those users who have already logged-in into our application, they are able to carry on their tasks.
We are using Application Server 10g 10.1.2.0.2. I have checked the status on Application Server through Oracle Enterprise Manager Console. The OC4J Instance is up and running. Also, server's configuration is pretty good. It is running on 2 CPUs (AMD Opteron 3GHz) and has 32GB of memory. The memory used by those 56 sessions is less than 3GB.
The Applicatin Server is running on a Microsoft Windows Server 2003 64bit Enterprise Edition.
Any help will be much appreciated.
Cheers

Hi Shekhawat
In Windows Registry go to
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\Session Manager\SubSystems
In the right hand side panel, you will find String Value as Windows. Now double click on it (Windows). In the pop up window you will see a string similar to the following one:
%SystemRoot%\system32\csrss.exe ObjectDirectory=\Windows SharedSection=1024,20480,768 Windows=On SubSystemType=Windows ServerDll=basesrv,1 ServerDll=winsrv:UserServerDllInitialization,3 ServerDll=winsrv:ConServerDllInitialization,2 ProfileControl=Off MaxRequestThreads=16
Now if you read it carefully in the above string, you will find this parameter
SharedSection=1024,20480,768
Here SharedSection specifies the system and desktop heaps using the following format:
SharedSection=xxxx,yyyy,zzzz
The default values are 1024,3072,512
All the values are in Kilobytes (KB)
xxxx = System-wide Heapsize. There is no need to modify this value.
yyyy = IO Desktop Heapsize. This is the heap for memory objects in the IO Desktop.
zzzz = Non-IO Desktop Heapsize. This is the heap for memory objects in the Non-IO Desktop.
On our server the values were as follows :
1024,20480,768
We changed the size of Non-IO desktop heapsize from 768 to 5112. With 5112 KB we managed to test our application for upto 495 virtual users.
Cheers

Servlets/JDBC vs. servlets/EJB performance comparison/benchmark

I have a PHB who believes that EJB has no ___performance___ benefit
against straightforward servlets/JSP/JDBC. Personally, I believe that
using EJB is more scalable instead of using servlets/JDBC with
connection pooling.
However, I am at a lost on how to prove it. There is all the theory, but
I would appreciate it if anyone has benchmarks or comparison of
servlets/JSP/JDBC and servlets/JSP/EJB performance, assuming that they
were tasked to do the same thing ( e.g. performance the same SQL
statement, on the same set of tables, etc. ).
Or some guide on how to setup such a benchmark and prove it internally.
In other words, the PHB needs numbers, showing performance and
scalability. In particular, I would like this to be in WLS 6.0.
Any help appreciated.

First off, whether you use servlets + JDBC or servlets + EJB, you'll
most likely spend much of your time in the database.
I would strongly suggest that you avoid the servlets + JDBC
architecture. If you want to do straight JDBC code, then it's
preferable to use a stateless session EJB between the presentation layer
and the persistence layer.
So, you should definitely consider an architecture where you have:
servlets/jsp --> stateless session ejb --> JDBC code
Your servlet / jsp layer handles presentation.
The stateless session EJB layer abstracts the persistence layer and
handles transaction demarcation.
Modularity is important here. There's no reason that your presentation
layer should be concerned with your persistence logic. Your application
might be re-used or later enhanced with an Entity EJB, or JCA Connector,
or a JMS queue providing the persistence layer.
Also, you will usually have web or graphic designers who are modifying
the web pages. Generally, they should not be exposed to transactions
and jdbc code.
We optimize the RMI calls so they are just local method calls. The
stateless session ejb instances are pooled. You won't see much if any
performance overhead.

Using Test Setting file to run web performance tests in different environments

Hello,
I have a set of web performance tests that I want to be able to run in different environments.
Currently I have csv file containing the url of the load balancer of the particular environment I want to run the load test containing the web performance tests in, and to run it in a different environment I just edit this csv file.
Is it possible to use the test settings file to point the web performance tests at a particular environment?
I am using VSTS 2012 Ultimate.
Thanks

Instead of using the testsettings I suggest using the "Parameterize web servers" command (found via context menu on the web test, or via one of the icons). The left hand column then suggests context parameter names for the parameterised web server
URLs. It should be possible to use data source entries instead. You may need to wrap the data source accesses in doubled curly braces if editing via the "Parameterize web servers" window.
Regards
Adrian

ActiveX Control recording but not playing back in a VS 2012 Web Performance Test

I am testing an application that loads an Active X control for entering some login information. While recording, this control works fine and I am able to enter information and it is recorded. However on playback in the playback window it has the error "An
add-on for this website failed to run. Check the security settings in Internet Options for potential conflicts."
Window 7 OS 64 bit
IE 8 recorded on 32 bit version
I see no obvious security conflicts. This runs fine when navigating through manually and recording. It is only during playback where this error occurs.

Hi IndyJason,
Thank you for posting in MSDN forum.
As you said that you could not playback the Active X control successfully in web performance test. I know that the ActiveX controls in your Web application will fall into three categories, depending on how they work at the HTTP level.
Reference:
https://msdn.microsoft.com/en-us/library/ms404678%28v=vs.110%29.aspx?f=255&MSPPError=-2147217396
I found that this confusion may be come from the browser preview in the Web test result viewer. The Web Performance Test Results Viewer does not allow script or ActiveX controls to run, because the Web performance test engine does not run the, and for security
reasons.
For more information, please you refer to this follwoing blog(Web Tests Can Succeed Even Though It Appears They Failed Part):
