There are a number of community modules to support clustering, using different techniques to communicate changes between nodes.
But these are community modules (so they have are seeking developers and/or funding - and have not attracted sufficient investment to meet documentation / testing requirements to be included out of the box as a geoserver extension). Given your experience in setting up everything thus far perhaps you are in a particpation to contribute? Community modules are available as nightly builds (for feedback), or you could download the GeoServer 2.21.1 source code and build the community modules for that specific release. As you are already using JMS I recommend https://docs.geoserver.org/latest/en/user/community/jms-cluster/index.html There is also the database based clustering https://docs.geoserver.org/latest/en/user/community/jdbcconfig/index.html And the spring boot based https://github.com/geoserver/geoserver-cloud -- Jody Garnett On Nov 23, 2023 at 8:22:41 AM, Kosta Cavic via Geoserver-users < geoserver-users@lists.sourceforge.net> wrote: > Hi guys, > > I have setup demo Geoserver HA cluster using peer-to-peer out-of-box > approach with shared directory using NFS. > Setup is following: > - 2 virtual instances with exact same configuration using embedded brokers > with multicast, > - Oracle Linux 8.x, > - Jetty version that Geoserver app is using, exact same version, > - Geoserver 2.23.1, > - OpenJDK 17. > For cluster instance names are *instancename1(instancename2).domainname.com > <http://domainname.com/>*. > Same setting applies for embedded broker configuration. > Configurations for cluster and broker are in separate directories. > > Scenario will not include many configuration changes and that is why > peer-to-peer approach. > > Instance discovery works fine, traffic is visible, they interconnect using > embedded brokers. > However, instances do not communicate any change between themselves. > When I failover instance, no configuration change (even small one) has > been changed between instances. > I have checked queues on both instances, tested traffic via queues, and > ActiveMQ works. > Only, when testing queues I have JMS response "no instanceName is set", > hence I saw that instanceName is embedded in ObjectMessage body. > Also, client.JMSContainer component constantly logs message "... did not > receive a message", because there is no producer. > Is there any Geoserver webapp parameter or webapp wiring parameter that > can enable Geoserver webapp to produce messages via JMS or what can be > wrong here? > > Thanks in advance! > > BR, > > > > *Kosta Čavić* > > *DevOps Engineer* > > > > High Tech Engineering Center llc. > > Mladena Stojanovića 30, 78000 Banja Luka, RS, BiH > > Phone: +381 (0)65 481 640 > > Skype: kosta.cavic > > <http://htecgroup.com/> > > _______________________________________________ > Geoserver-users mailing list > > Please make sure you read the following two resources before posting to > this list: > - Earning your support instead of buying it, but Ian Turton: > http://www.ianturton.com/talks/foss4g.html#/ > - The GeoServer user list posting guidelines: > http://geoserver.org/comm/userlist-guidelines.html > > If you want to request a feature or an improvement, also see this: > https://github.com/geoserver/geoserver/wiki/Successfully-requesting-and-integrating-new-features-and-improvements-in-GeoServer > > > Geoserver-users@lists.sourceforge.net > https://lists.sourceforge.net/lists/listinfo/geoserver-users >
