Cognos performance testing

Jump to solution
Hi,

Is any one knows how to stress test Cognos 8.4 application.


We are planning to do performance testing Cognos 8.4 with Loadrunner 9.1.

I recorded a script with web(HTTP/HTML) protocal.
Report will take longer time to display,
during that time on web page it displaying 'Report is running', in script it created below code several times

web_submit_data("cognos.cgi_3",
"Action=http://whtwcogw1.sarm.net/cognos8/cgi-bin/cognos.cgi",
.
.
.
web_submit_data("cognos.cgi_9",
"Action=http://whtwcogw1.sarm.net/cognos8/cgi-bin/cognos.cgi",

finally report is generated.

Web_reg_find() function not able to capture 'Report is running' text.
If I run the script as it is it running vey fast and at the end report is not displaying.

Not sure what logic we have to use in side the script so that script should wait till the report get generated.


Thanks

Ravi,
We will be attempting to use LR to test Cognos soon, as well. We have not started yet, but I did find a document on IBM's website about best practices using LR to test Cognos. It looks very informative, and I think it will address your need. I hope this helps.

Joshua S,

Is your Cognos performance testing started?
If yes, are you able to prepare scripts?

Thanks

We have actually determined that, at this time, we do not require LoadRunner for our testing because we are only looking at approximately 10-15 concurrent users. So instead, we plan to use QTP for this testing because it is easier to script. Sorry, I won't be of any more help.
