A sample (wicket) webapp for playing with memcached-session-manager (msm). It comes with two tomcats (in runtime/) that are configured with msm+kryo (msm kryo-serializer) storing sessions in memcached.

This sample comes with two tomcat instances (in runtime/, tomcat1 and tomcat2) that are configured with msm+kryo (msm kryo-serializer) for non-sticky sessions by default.

To change the stickyness you can switch via ./switch-stickyness.sh sticky|nonsticky. Btw, there are 2 different tomcat versions available in runtime/ (6.0.32 and 7.0.8), you can switch them via ./switch-tomcat.sh 7.0.8 or ./switch-tomcat.sh 6.0.32.

Prerequisites

  1. Maven: you should have installed maven to be able to build the webapp.
  2. memcached: you should have installed memcached so that you can run the webapp with sessions replicated to memcached
  3. I don't mention java here :-)

Building the webapp / war file

  1. Build the web application: $ mvn package

Running the webapp

You can run the webapp using the preconfigured tomcats in runtime/. Before you start tomcat, make sure that you have started two memcached nodes: $ memcached -p 11211 -u memcached -m 64 -M -vv & $ memcached -p 11212 -u memcached -m 64 -M -vv & This is the cmd line that I'm using on my system with memcached installed using the memcached user. -vv tells memcached to write lots of stuff to stdout, so you'll see when a session is requested or stored in the output of memcached.

To start both tomcats just run $ ./runtime/tomcat1/bin/catalina.sh run & $ ./runtime/tomcat2/bin/catalina.sh run &

Now you can access both tomcats with your browser on http://localhost:8081/ and http://localhost:8082/. To simulate a loadbalancer in front of your tomcats and a session failover just request the same url on the other tomcat (just change to port in the url).
