What to do next
You need to configure Hazelcast in the TCP/IP mode to enable discovering cluster members by
using TCP. When you configure Hazelcast to discover members by TCP/IP, you must list all or
a subset of the members' hostnames, IP addresses or both as the cluster members. You do not
have to list all of the cluster members, but at least one of the listed members must be
active in the cluster when a new member joins. To set your Hazelcast to be a full TCP/IP
cluster, set the following configuration elements:
- Set the enabled attribute of the multicast element to "false".
- Set the enabled attribute of the aws element to "false".
- Set the enabled attribute of the tcp-ip element to "true".
- Set your member elements within the tcp-ip element.
