We are testing the Quality Center9.0 server performance by using the Load Runner8.1. We generated a load script on QC 9.0 for Login and Logout functionality with WEB HTTP/HTML) protocol, URL based script. When we are trying to execute the script.
The web_set_user function is how you set the authorization credentials in LoadRunner. Put it at the top of your vuser_init before running anything else. If you are sure the web_set_user is not working, we need more information.
