Hazelcast
How large/small of a port range (how many Ports) needs to be available/reserved for Hazelcast for an application on each of the three VMs that host an application server instance?
There will be multiple/different applications running on the same 3 VM that host the JVMs for each unique application.
Does it need to be 99, 49, or can it be less....
Port range
By default, a Pega node uses port range 5701 to 5800 for Hazelcast. In an environment where a different range is required, use the prconfig.xml property cluster/hazelcast/ports to set the range.
prconfig.xml example
<env name="cluster/Hazelcast/ports" value="5701-5750" />
DSS example
Setting Purpose: prconfig/cluster/hazelcast/ports/default Value: 5701-5750 Owning Ruleset: Pega-Engine

Hi @EdwardW8182: Not sure on what is requested on 99 or 49. In general if you are running multiple PEGA deployments in a same host, the recommendation is to specify different port range in the individual deployments (prconfig.xml / DSS) so that there will not be any port conflicts.
Reference for additional details here.
Thanks.

Hello,
For same setup, 3 applications in a single VM, I've set <env name="cluster/hazelcast/ports" value="5701-5720" /> <env name="cluster/hazelcast/ports" value="5721-5735" /> <env name="cluster/hazelcast/ports" value="5736-5750" />
You also need to set different port name for all stream values <env name="dsm/services/stream/pyBrokerPort" value="9092" /> <env name="dsm/services/stream/pyKeeperPort" value="2181" /> <env name="dsm/services/stream/pyJmxPort" value="9999" /> <env name="dsm/services/stream/pyPort" value="7003" /> I did -1 for all above stream port for the 2nd server, -2 for the 3rd server. By hardcoding, you avoid conflicts in any case.

@EdwardW8182 tiny fishing I think by default, a Pega node uses port range 5701 to 5800 for Hazelcast. If a different port range is required for Hazelcast due to potential conflicts or other reasons, you can customize this range using the prconfig.xml property cluster/Hazelcast/ports.
The flexibility provided by the ability to set a specific port range using prconfig.xml or Data System Settings (DSS) allows you to tailor the port range to suit the requirements of your specific environment.
