I want to simulate 200 concurrent users logging in and performing some basic tasks in QC 9.2(Creating a new defect/requirement etc). We have access only to VUGen through Load runner. I want to know if we can create and run 200 virtual users using VUGen alone? Is it possible to create 200 concurrent users and create 'n' no. of iterations of the activities the users would be performing through VUGen? We dont have access to Controllers either..
Do you have 200 desktops? If so, have at it. Install VUGen on each, copy the scripts to each. Have 200 persons hit Go simultaneously and stand back for the fireworks.
If not, but you want to leverage your VUGen script, you'll need to get a Controller.
If not and you could care less about your VUGen script, consider open source tools to accomplish this task.
Just as an FYI, 200 concurrent users is pretty heavy usage for QC. Have you sized that correctly?
I think moreover the problem is going to lie in that you will need to create 200 users in Quality Center.
You need to plan ahead on this a little and determine if you want to go with individual QC users non attached to the network, or LDAP associated users. My suggestion would be to use what you are expecting to use in the real workld usage. If it is the LDAP users, you will need to make sure to coordinate with your network support group to ensure those dummy accounts are created (and destroyed) correctly.
Yeah, we have licenses to support 200 concurrent users. We have multiple QC servers connected to a load balancer..so it means approx 70 concurrent users per server.
We'v had the users created for us but somehow VUGen isnt capturing and replaying the actions correctly. Seems it gets held up with processes at client end only and doesnt get to reach to QC server to fetch server response :-(
