Since we originally deployed CAS, a sample configuration file for Jboss
Cache has been distributed with the CAS server (
https://www.ja-sig.org/svn/cas3/tags/cas-3-2-1-final/cas-server-integration-
jboss/src/test/resources/jbossTestCache.xml ).  Upon comparing it with our
current configuration, I have noticed there have been several discrepancies,
which I hoped could be explained.

JGroups discrepancies
1. <FD> has been commented out in favor of <FD_SOCK>
2. <pbcast.NAKACK> and <UNICAST> are both used
3. <FRAG> has been included

JBoss Cache Discrepancies
1. UseReplQueue, ReplQueueInterval, ReplQueueMaxElements are declared but
are only used by asynchronous replication
2. TransactionManager is specified yet the online documentation for cluster
has it being removed (
http://www.ja-sig.org/wiki/display/CASUM/Clustering+CAS )

My primary focus is on the JGroup changes as I don¹t know if FD_SOCK uses
the same notion of shunning as FD.  The source behind FD_SOCK shows removal
of suspect members and broadcasting the removal to the cluster, so it should
be okay.  I am also curious why the <FRAG> entity was introduced; were
people having replication packets that were too large or being blocked due
to size?

Thanks,
Andrew
