How do I change connector communication to prioritize hostname first then IP address second?

Preferred Communication Method

By default, JetPatch prioritizes IP address over the hostname.  If you prefer hostname first, you can change this via intigua.properties. After making the desired changes, restart tomcat. 

#use hostname as a preferred address of communication
ep.communication.prefer-hostname.enabled=false #default false

#fallback to IP if hostname connection failed
ep.communication.prefer-hostname.ip-fallback=true #default true

Merging Endpoint Records on Hostname Only

It is also possible to set via intigua.properties the Endpoint uniqueness policy to use hostname only.

This will cause a merger of discovered endpoints only on the basis of the hostname and not consider the IP or MAC address, which all three are used by default.

#use hostname as a preferred address of communication
endpoint.merge.hostname-only=true #default false

Note - This capability is available starting from JetPatch 4.1.0.104
