I have a small cluster of 3 nodes running tomcat 6.0.24 with openJDK 1.6.0_20 on Ubuntu 10.04 LTS.
I have roughly 5,000-6,000 sessions at any given time, and when I restart one of the nodes I am finding that not all sessions are getting replicated , even when I have the state transfer timeout set to 60 seconds. It seems that only sessions that have been touched recently are replicated, even if the session is still otherwise valid. I did one test where I created about 1,500 sessions and then took out one node, When I brought it back online, it only replicated the 4-5 sessions that were from active users on the test cluster. It did not replicated the idle sessions that were still valid that my prior test had created. I am wanting to tune my settings, but I am unsure where would be the best place to start. Should I start with the threads available to the NIO Receiver, or would I be better off focusing on a different set of attributes first, such as the send or receive timeout values? Any tips or pointers as to which setting might be the most productive would be greatly appreciated.
