Summary
Hazelcast is a third-party technology that is used when Confluence Data Center is installed in a cluster. It is used by Confluence and Synchrony. For details on those ports, check the document below:
Solution
Hazelcast port for Confluence
The Hazelcast port for Confluence can be changed by using the confluence.cluster.hazelcast.listenPort system property. See Configuring+System+Properties to find out the various ways system properties can be set in your site.
If the confluence.cluster.hazelcast.listenPort system property is not present, the Hazelcast port for Confluence will default to port 5801.
Hazelcast port for Synchrony
The Hazelcast port for Synchrony can be changed by using the cluster.listen.port property. The way this property is passed to Synchrony depends on how you run Synchrony.
If you run a Synchrony standalone cluster, the Hazelcast port is customized by adding the
cluster.listen.portproperty in thestart-synchrony.shorstart-synchront.batscript.If you use managed Synchrony, the Hazelcast port is customized by adding the
cluster.listen.portproperty to thesynchrony-args.propertiesfile.
If the cluster.listen.port property is not present, the Hazelcast port for Synchrony will default to port 5701.
