- How do I switch clustering to TCP instead of multicast UDP in EAP 6? https://access.redhat.com/solutions/140103
Internal
Procedure
Switch to a "tcp" Default Stack
Manual
Locate the "jgroups" subsystem in standalone.xml or domain.xml relevant profile, and set default-stack value to "tcp":
... <subsystem xmlns="urn:jboss:domain:jgroups:1.1" default-stack="tcp"> ...
CLI
/subsystem=jgroups:write-attribute(name=default-stack,value=tcp)
Note that the operation requires reload, but you should reload the server configuration only after the entire procedure is complete (see reload)
Replace the MPING protocol with TCPPING
Manual
Locate the "tcp" stack inside the "jgroups" subsystem and replace the MPING protocol with TCPPING:
... <stack name="tcp"> <transport type="TCP" socket-binding="jgroups-tcp"/> <protocol type="TCPPING"> <property name="initial_hosts">1.2.3.4[7600],1.2.3.5[7600]</property> <property name="num_initial_members">2</property> <property name="port_range">0</property> <property name="timeout">2000</property> </protocol> <!--<protocol type="MPING" socket-binding="jgroups-mping"/>--> <protocol type="MERGE2"/> ... </stack>
