We have it set to true. The developers are serializing way more than
they should be to the session though..

cris,
what is your useDirtyFlag set to in the server.xml.
This should be set to true, if you wanna optimize the session
replication performance.

Thanks for the link. Let me be more specific. I want to share some info
across Tomcats that are using web services. They need to read/write to this
common area. 

Can this backport do that?

RE: Clustering applications

2003-08-14 Thread Cristopher Daniluk
We use tomcat-replication.jar, which is the backport that someone else
mentioned earlier. It works well as a failover tool, but there is a
slight delay in replication. Maybe tuning could alleviate that but I
think with rapid browsing, it may not be able to keep up. We use the
replication for failover support, but we still keep sticky sessions via
a jvmRoute..

Suppose I wanted to set up Tomcat and share some common info across apps
running on the instances of Tomcat. How would I do this?

When googling for a bit, I came across JavaSpaces. Is anyone else using
this, or is that barking up the wrong tree?


Thanks,

Hi,

Tomcat 5 has this functionality.  The code has been backported to Tomcat
4.  It's in CVS somewhere (the place escapes me) but if you search the
list archives you will find it.

yeah, the current clustering is an all to all node replication,
If I find time I will optimize that
