Hi,
I am new in Jmeter and facing problem while load testing my web application.
I am using jmeter version 2.3.2 for my project.
I have created a test plan of using 4 thread groups and 280 concurrent
threads.
-----
-Test plan
- synchronize Timer (set 280 threads)
- Thread Group (users = 90, ramp-up periord = 0)
a. this thread group hs 12 sample requests
- Thread Group (users = 90, ramp-up periord = 0)
a. this thread group hs 12 sample requests
- Thread Group (users = 50, ramp-up periord = 0)
a. this thread group hs 12 sample requests
- Thread Group (users = 50, ramp-up periord = 0)
a. this thread group hs 12 sample requests
- View Results tree
- View Results in table
- Aggregate reports
-----
12 sample requests are ->
1. HIt the home page of an web application
2. Click on a product tab. http request to open the corresponding product
page
3. The product page has 9 products images. Those images have URL
4. 1-9 http requests for p product images
5. http request for a product detail page
For few sample requests I got the below exception.
java.net.ConnectException: Connection refused: connect at

Questions-
1. What is this exception means and how can I resolve my problem?
2. I need to do load test my web application for 2500 Concurrent
users. Currently what I’m doing is this is the correct approach? Concurrent
means all 2500 Users will hit the home page http request at the same
time.Once the ist sample request is completed then it wil proceed to the
next http sample request.
This is an urgent requirement for my project.
Thanks
Maumita
