Hi Theo,
Since you are using static membership and NOT dynamic(multi-cast) which
auto-detect members, my current understanding says that you will have to
add entry of all the members of your cluster in each of nodes server.xml.
Example:
My cluster has two nodes. So to configure these I had add these two members
entries in both node's server.xml(since running on the same machine, they
have varying port with same ip):
<Interceptor
className="org.apache.catalina.tribes.group.interceptors.StaticMembershipInterceptor">
<Member
className="org.apache.catalina.tribes.membership.StaticMember"
port="4000"
host="192.168.1.6"
uniqueId="{10,1,0,100,0,0,0,0,0,0,0,0,0,0,0,0}"/>
<Member
className="org.apache.catalina.tribes.membership.StaticMember"
port="4001"
host="192.168.1.6"
uniqueId="{10,1,0,101,0,0,0,0,0,0,0,0,0,0,0,0}"/>
Regards,
Ameer Mawia
