While recovering from split-brain (network partitioning),
map entries in the small cluster will merge into the bigger cluster

cluster, there might an existing entry with the same key already.
Values of these entries might be different for that same key.
Which value should be set for the key? Conflict is resolved by
the policy set here. Default policy is hz.ADD_NEW_ENTRY
There are built-in merge policies such as
hz.NO_MERGE ; no entry will merge.
hz.ADD_NEW_ENTRY ; entry will be added if the merging entry's key
doesn't exist in the cluster.
hz.HIGHER_HITS ; entry with the higher hits wins.
hz.LATEST_UPDATE ; entry with the latest update wins.

View file @ c3479bdb
After you have licensed and downloaded Coherence EE from Oracle, place
the following jar files in this folder:
coherence.jar
coherence-work.jar
To build the clustering plugin, issue the following command from
the Openfire (source) /build/ folder:
$OPENFIRE_SRC/build> ant -Dplugin=clustering plugin
Also note that due to classpath loading order, it may be necessary to
either remove the coherence-cache-config.xml file from the Coherence
runtime JAR, or rename the plugin-clustering.jar file to force it to
load before coherence.jar (e.g. "clustering-plugin.jar" or similar).
In order to run Oracle Coherence in production mode, you will need to
secure licensing for the Enterprise Edition (EE) of Coherence. While
clustered caching for Openfire is available in the Standard Edition (SE),
per the Oracle Fusion licensing docs the InvocationService (which is
used by Openfire to distribute tasks among the cluster members) is only
available in EE or Grid Edition (GE).
Note that Coherence is configured to run GE in development mode by default.
You can change this setting by overriding the following Java system properties
via /etc/sysconfig/openfire (RPM) or openfired.vmoptions (Windows):
-Dtangosol.coherence.edition=EE
-Dtangosol.coherence.mode=prod
The current Coherence release is version 3.7.1.

<h1>
Hazelcast Clustering Plugin Readme
</h1>
<h2>Overview</h2>
<p>
The Hazelcast plugin adds support for running multiple redundant Openfire
servers together in a cluster. By running Openfire in a cluster, you can
distribute the connection load among several servers, as well as having some
form of failover in the event that one of your servers dies. This plugin
is a drop-in replacement for the original Openfire clustering plugin that
removes the dependency on an expensive proprietary third-party product.
</p><p>
The current Hazelcast release is version 2.3.1.</p>
