Hi,
We are currently using a product called Terracotta to do session
fail-over/replication but are considering moving away from this product as
it doesn't seem to support Java 7 and Tomcat 7.
What products exist out there that would help with session
fail-over/replication? I only know of 3:

Hi,
I am using Apache 2.2.3 with mod_jk 1.2.31 and Tomcat 6.0.30 .
I have never had issues with using mod_jk to connect my Apache requests to
a tomcat instance before now but I am now running into a situation where
Apache requests going to a tomcat instance on another server are giving me
an 400

I'm trying to help out my old company who has no IT staff to look at this.
This might be a bad coding issue but I'm hoping to be able to understand
this issue.

Hi,
I am testing the jdbc pool to replace the c3p0 pool we were using for our
Tomcat connection pool. We are also using Spring 2.0 and Hibernate (and
Tomcat 6).
When I put this in my hibernate-context.xml, our application is using the
jdbc pool and appears to work:

Hi,
There might be better ways but I monitor the c3p0 connection pool using
jmxterm (my jar jmxterm-1.0-alpha-4-uber.jar).
For c3p0, the mbean is com.mchange.Pooled...
Hope this helps a little!

Hi,
Not sure if this is the same issue but I believe you might need the
tcp_tw_reuse and tcp_tw_recycle parameters in /proc/sys/net/ipv4 to be at
a value of 1? Since you already achieved 1 connections, I'm thinking
it's probably something else though.

Hi,
I had a thread a while back but my configuration has changed and so has my

My config:

setting of 18

To add to this, apache seems to be hung up as well as it can't even serve
