Threads limit & tomcat sessions?

Hi, I am running JMeter to simulate 180 concurrent users. I have 5 machines, each running approx 40 threads in the thread group. Everything seems to be running fine for a while...and then I am seeing problems with tomcat sessions - items that are put in the session at the top of the plan don't

Re: Help with random submission but constant throughput

I've heard that it's best to use a maximum of 20 threads per thread group. Is this correct? Is it just for memory usage? Does that mean 20 threads per plan, or is it okay to have multiple thread groups, each with 20 threads (but running concurrently). To simulate 180 users, how many machines w

Help with random submission but constant throughput

Hi, I am trying to simulate 180 users hitting a web site randomly, but know that the throughput should be the web site submitting 1 job every 2 seconds to the backend. Any ideas how to combine random rate and yet still control the throughput? Many thanks, David

Re: Constant Throughput with loop

sure. I'd like to have a controller that encapsulates a bunch of jdbc calls underneath it eg "submit job" I'd then like to measure the throughput of how often the controller get's executed - at the moment I get the throughput of all the jdbc calls that are exectuted, right? I'd like to know "ho

Re: Constant Throughput with loop

Sorry - my bad. Figured out that it is all done per thread, so that was what was confusing me! Would still like to have a constant throughput for the number of times a controller is executed, though. Is there a way to do this without having to count everything within that controller? Cheers, D

Constant Throughput with loop

Hi, I'm trying to get a constant throughput in a test plan that includes a loop. I tried the Constant Throughput Timer first with just a single JDBC call, and it works fine if there is no loop. However, placing the call in a loop makes it all goes wierd (doesn't keep throughput constant, seems

I keep getting the following random exception, when I just click on items in the test plan on the left hand side. Any ideas? Cheers, David java.lang.NullPointerException at sun.java2d.pipe.DrawImage.copyImage(DrawImage.java:50) at sun.java2d.pipe.DrawImage.copyImage(DrawImage.j
