Running a Cluster with -default Possible for Security Reason

gcarlisle Jan 22, 2008 10:45 AM

Hello everyone I'm new to Jboss clustering but I have all of the guides that I could possibly get my hands on and I have successfully set up a jboss cluster making some of the recommended changes like setting the HApartition via the jboss.default.partition system property etc and I am currently in the process of testing load balancing. (hope all goes well!)

My question is about running a cluster using -default instead of -all. The system will be in a secure location and there are some concerns about running -all. Is there a way to run a cluster in -default and add the necessary jar files, service files etc and make it work? Or do we just need to run in it in -all and look it down accordingly from there?

Any insight or guidance on this would be greatly appreciated.

Yeah, you can build up default to add clustering.

Suggest you start by copying default and making a "cluster" config. This way you'll still have the original clean default to start with.

Then copy jgroups.jar and jboss-cache.jar from all/lib to cluster/lib. If it's there in all/lib and not in cluster/lib also bring over jboss-serialization.jar.

Then see the http://wiki.jboss.org/wiki/Wiki.jsp?page=JBossASTuningSliming wiki page; near the bottom there is a " If you do not use clustering" section. That shows how to remove clustering services from "all". Use that as a guide to tell you what you need to bring over from "all" into your "cluster" config.

Can't guarantee you won't hit some bumps, but that should get you far enough down the road.

Thanks for the guidance on this. Skimmed over the tuning guide and your suggestion makes sense. Thanks for the help!

Forgot; you'll also need jbossha.jar from all/lib.
