(Not applicable to Online Data Proxy) Unwired Servers communicate with other Unwired Servers in the same cluster differently, depending on the type of communication performed.
- If multiple servers are used to perform replication synchronization, use the secure replication ports to negotiate which server will act as the primary synchronization server.
- If multiple servers perform cluster and domain configuration synchronization, use HTTP listeners. If a shared disk is used, the nodes do not use any network protocol for the file transfers; instead, they just access the disk.
- If multiple servers need to exchange JMS messages, they communicate indirectly through the shared databases of the data tier
over IIOPS.
