[Geoserver-users] Geoserver Clustering Issue

Hi everyone,
I am facing problems regarding clustering. I'm unable to communicate
geoserver across multiple servers. Multiple geoservers on one machine or vm
with perfect and catalog is updated when changes are made to one node. But
I'm unable to send these changes over network to other machines. Any
guidence please?

Hi,

Question is OK but I guess that there are not so many users running Geoservers in clusters. Problem "But I'm unable to send these changes over network to other machines" makes me feel that it could have something to do with general network and firewall configuration.

Thank you for the reply. First of all i think network isn't an issue here,
I've tested my network supports multicast. Vertical clustering works well
and changes are submitted to instances running on same machine bit changes
on other machines aren't broadcasted. It has something to do with the
geoserver clustering i believe rather than general network.

A goo search for “geoserver cluster” turns up lots of resources that describe various ways to implement clustering. Here’s a good one:

Thank you for the reply Martin, I've followed all the tutorials and they all
lead to vertical clustering (same machine with multiple instances) none of
them explains how to achieve horizontal clustering, though geo solutilns
themselves claim horizontal clustering is possible.

Yes, we have several horizontally clusted installations in production using
this module:

Thanks Andrea for getting back to me.
I have followed this JMS clustering tutorial but still unable to configure.
I'll give it a shot within a day or two again.

Meanwhile little tip/trick i would like to ask all of you, I have Apache
HTTP server on one machine which forwards my tile requests to cluster on
another machine on which 5 concurrent instances of geoservers are running
under tomcat servlet container. How can i spead up tile requests from
multiple instances? My cluster is running with the same speed as a single
server would act.

Regards
