DescriptionWhen navigating to System > Settings > Security Management - Persistent Agent in the Administration UI, there is a field called Primary Host Name (Secondary Host Name as well in High Availability configurations). By default, these fields are blank.
When
populated with the Fully Qualified Host Name of the Application Server or Server, the name of the server
is pushed out to connecting host(s) and updates the ServerIP Persistent
Agent setting on those host(s). This is to ensure that the Persistent
Agent is communicating with the correct host in a distributed
environment. In a High Availability environment, the name pushed would
be the currently active server.
The ServerIP setting was used
in 2.x and lower versions of the Persistent Agent. 3.x and higher use
the HomeServer and AllowedServer settings. In certain situations,
however, inconsistent agent communication could still occur if the names
in the Host Name fields are not correct.
Scope
Version: 8.x
Solution
The Host Name fields in this screen should remain blank when using Persistent Agent versions 3.x and higher. Either DNS SRV records or software management should be used to distribute the server names to the Persistent Agents.
