Jmeter Load Testing Luminis 4 - 503 errors (too many outstanding requests)
We are finally getting around to doing load testing our Luminis 4 environment after having a problem with the start of registration every semester. I am using Jmeter 2.4. I have a full script that mimics what a user does during peak registration, it logs into the portal, (downloading all the graphics, css files, etc.) then switches to our registration tab, calls the cpip URL to single signon to banner, navigates to a couple of menus in banner, retrieves the users current registrations and logs out of luminis. I have some response assertions checking for failed logins, etc. At low levels of activity, the script works well and returns expected results. As I increase the load, it quickly starts getting 503 errors from Luminis:
Apache Tomcat/5.5.27 - Error report
HTTP Status 503 - You have too many outstanding requests - wait for them to complete and try again
It seems that Tomcat is cutting me off. Has anyone successfully load tested. Do I have to run distributed tests from many machines?
Any work arounds?
