I have two instances of Tomcat 7.0.8 running in the same machine (Tomcat7A and Tomcat7B) and IIS 7.5 acting as front-end load-balancer with isapi-redirector 1.2.31, running on Windows 2008 R2. When i disconnect the instance wich is handling a request i can see a new instance being assigned with the same sessionid but then the user is redirected to the login page.

1 Answer 1

Setting up a cluster on the Tomcat side which does session replication often involves more than just editing server.xml. Often you have to mark your applications as "distributable" in web.xml, and potentially do other things. Also, all of the classes you put into a session must implement the serializable interface.

Finally, beware the Jakarta ISAPI plugin for IIS - it is a port from Apache mod_jk, and is quite broken, at least at high load. We have a 7-server tomcat cluster (300 req/sec peaks) and eventually switched to using nginx on Linux on the front end instead of IIS because the ISAPI_redirect.dll would spontaneously stop serving anything at high load (with nothing in the error logs and no other evidence of problems in perfmon). IIS 7.5 Application request routing plugin might be a better option if you want to stay all-windows.

Hi thanks for the answer, i already had the <distributable> tag to my webapps, and it was working fine for most of the pages but now it redirects all the time with a new session_id. I will try with Application Request Routing plugin to see if its more stable. –  Jose Matias Apr 12 '11 at 13:18
