We have it set to true.

RE: Clustering applications
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.

RE: Clustering applications
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? -Original Message- From: Filip Hanik [mailto:[EMAIL PROTECTED] Sent: Tuesday, August 12, 2003 10:12 PM To: Tomcat Users List Subject: RE: Clustering applications http://cvs.apache.org/~fhanik/ Filip > -Original Message- > From: Eric J.

RE: Clustering applications
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..

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?

Re: Clustering applications
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. -e On Tue, 12 Aug 2003, Sean Leblanc wrote: > Suppose I wanted to set up Tomcat and share some common info across apps > running on the instances of Tomcat.

RE: Clustering applications
yeah, the current clustering is an all to all node replication, If I find time I will optimize that Filip > -Original Message- > From: Cristopher Daniluk [mailto:[EMAIL PROTECTED] > Sent: Wednesday, August 13, 2003 9:00 AM > To: 'Tomcat Users List' > Subject: RE: Clustering applications > > > We have it set to true.
