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>

CLI

/subsystem=jgroups/stack=tcp:remove-protocol(type=MPING)
/subsystem=jgroups/stack=tcp:add-protocol(type=TCPPING)
/subsystem=jgroups/stack=tcp/protocol=TCPPING/property=initial_hosts:add(value="1.2.3.4[7600],1.2.3.5[7600]")
/subsystem=jgroups/stack=tcp/protocol=TCPPING/property=num_initial_members:add(value=2)
/subsystem=jgroups/stack=tcp/protocol=TCPPING/property=port_range:add(value=0)
/subsystem=jgroups/stack=tcp/protocol=TCPPING/property=timeout:add(value=2000)

Note that the operation requires reload (see reload)
