20.13.3.2. Configuring JGroups Discovery Group on the Server
The example shown below defines a JGroups discovery group:
<discovery-groups>
<discovery-group name="dg-group1">
<jgroups-stack>udp</jgroups-stack>
<jgroups-channel>udp</jgroups-channel>
<refresh-timeout>10000</refresh-timeout>
</discovery-group>
</discovery-groups>
The JGroups discovery group definition uses two main attributes:
jgroups-stackattribute: This denotes the name of a stack defined in theorg.jboss.as.clustering.jgroupssubsystemjgroups-channelattribute: This attribute denotes the channel which JGroups channels connect to for receiving broadcasts
Note
JGroup attributes and UDP specific attributes are exclusive. You can use either JGroup or UDP set of attributes in the configuration of a discovery group or a broadcast group
