Mention that you can use JDBC_PING in jgroups.xml instead of TCPPING, with example.
It does not require to specify full list of members.
It requires a relational DBMS but of course any CUBA app has it.
Example for PostgreSQL and default CUBA datasource JNDI name:
<JDBC_PING async_discovery="true"
datasource_jndi_name="java:comp/env/jdbc/CubaDS"
initialize_sql="create table if not exists JGROUPSPING (
own_addr varchar(200) not null,
cluster_name varchar(200) not null,
ping_data bytea,
primary key (own_addr, cluster_name))"/>
