Hi, I'm chasing down details about the "standalone clustering" (as included
in Beta3) for documentation.
I've noted the following:
1 - There's a clustering-standalone.xml configuration file in standalone/configuration
that you can start the server with using ./standalone.sh
-server-config=clustering-standalone.xml
2 - This configuration differs from the standard config in that:
- the org.jboss.as.clustering extension is enabled
- some additional items are configured in the urn:jboss:domain:osgi:1.0 subsystem
- 2 new subsystems configured (jgroups and infinispan)
- 6 new socket bindings added to the standard-sockets group for jgroups
So exactly what feature set does this give you out of the box for clustering?
I'm guessing session replication between standalone instances with JGroups for
intra-node communication and Infinispan for storage?
Anything else?
Other questions:
How does each instance determine which other instances it should be clustered with?
Does this work with multiple instances on one machine (multi-homed or on different ports)?
Can multiple standalone instances using "cluster" configuration live on the same
network but not all be one cluster? Like 10 instances as 2 clusters of 5 for example?
Aside from centralized management, what are the other key features from domain mode that
you won't get from standalone clustering ?
Are there any known changes that are going to be made to this feature set for GA ?
Thanks in advance.
