If its working when you're not recording, probably it is an issue between the ActiveX plugin and the LR recoding module. You can try a couple things if that's the case: Recording it with another browser. This already happened with me. IE was crashing when recording and I had to record the script with Firefox, which uses a different plugin. If that doesn't help, you can try changing the recoding mode to a lower level, like HTTP/HTML in URL mode (Options > Recording > URL-based Script) Martin Does it work when you’re not recording with LR??

Oracle form is linked to 170 Markview solution. When I click on the oracle form, it opens a url which inturn download a plugin(activex plugin) for markview. while recording its starts downloading but do not open the markview page. Instead it gives error on browser stating object does not support property or method. This happens if I have tried to open it first time on a system. So if this plugin is already installed and then if I try to record it give an error stating that " not able to open configuration file of plugin" Thanks Martin I was able to record the oracle 11i but facing another issue.

I can say that about 90 of the strange issue I had recording Oracle apps had something to do with the Java version and JInitiator. Try removing both and start fresh. Alos, does it work when LR is not recording?? I already faced a similar issue with an application where LR was interfering with a ActiveX control installed on the browser. If that's the case, it could be interesting removing some unused ActiveX controls from IE6.

What happens in application is that when I click on that link it initiate downloading of some jar files and Jinitiator1.1.1.25, then it opens oracle form and also one another page which says applet started and message stating that ” closing this window will cause oracle based application to close immediately”. So while recording when I click on the link to open oracle form, IE(V 6.0) crashes and I am not able to record .

I had some issues with 12, some additional parameters are needed. Also, in some cases, the port number returned by the Oracle server is wrong and I had to manually change it, ignoring the correlation and using a pre-defined parameter. Please let me know it this helps, otherwise I could check the code. Rgds, Martin Hi Gaby,

All correlation of sessions are in order. Using LR 9.51

The server does not even see any attempt to connect, so I suspect Oracle NCA not configured correctly, and the request does not hit the server. Any tips how to trace further?

]]> Comment on How to evaluate the response time of a Citrix application by Martin http://e-mojo.net/how-to-evaluate-the-response-time-of-a-citrix-application/comment-page-1#comment-134 Martin Sun, 17 Jan 2010 23:50:40 +0000 http://e-mojo.net/martin_spier/?p=94#comment-134 Hi Ram, glad you found the article useful and thanks for the comment! Apart from this solution, I've already used several proprietary tools to test Citrix applications and find response times for specific transactions, including LoadRunner. I like to use this estimation approach to evaluate response times on Citrix when there is no need for hard data and also not much time to record scripts, but sometimes it is necessary to create a simulation, using LoadRunner or any other tool. As I mentioned, the biggest challenge on recording this kind of script is synchronizing the actions. As you mentioned, LoadRunner records the processing time as think time, which is not useful for measuring the real response from the application. In order to measure the correct time, we have to change the recorded think time commands for synchronization commands, like a wait for window or an update on the screen. I've posted a link to a very interesting article about this issue <a href="http://e-mojo.net/recording-citrix-scripts-loadrunner" rel="nofollow">here</a>. Please have a look and see if it can help you. And keep in mind that it takes some time to get every sync right.. ;-) Cheers, Martin Hi Ram,

All i wanted to know is, with respect to Loadrunner synchronization is the only way to calculate the response time. Is there any way where load runner helps us in finding the response time. for example when an key stroke like "ENTER", "TAB" it goes faster and it does wait for any event to appear. Likewise when you click on the picklist in an screen it takes time to retrive data from the database and this is recorded as think time in CITRIX protocol. Please don't mistake these are few of my clarifications. Hi, It is a good post. All i wanted to know is, with respect to Loadrunner synchronization is the only way to calculate the response time.

What can happen sometimes is that Oracle returns the wrong port number on that variable. Check if 61048 is the correct port and if it's not, set a static port number on the nca_connect_server call and try executing again. Cheers, Martin Hi Chetan,
