Subject Inconsistent Horizontal Tomcat Cluster with Apache Load-Balancing (Windows)
Date Fri, 11 Sep 2009 14:33:02 GMT
Windows Server 2003
Tomcat 6.0.20
Apache HTTP Server 2.2.11
JK 1.2.28 Connector

The goal is to have horizontal clustering with load balancing and failover
(session persistence).

The load balancing aspect works as expected. The issue I've been having is
that when ServerA crashes, it will swap over to ServerB and the session will
persist; however, if ServerB crashes, it will swap over to ServerA but lose
the session.
In the log files for ServerB:
INFO: Manager [/test-app]: skipping state transfer. No members active in
cluster group.

I've been struggling with making this work over the past couple months with
no luck. I've found several resources on the web, but they have a lot of
conflicting information even when they say they are accomplishing the same
end result.
Thank you for your time.
