Manage communication between galaxy nodes

You can use Application Server in a distributed environment. All computers with System Platform software installed must be able to communicate with each other.

Two items must be considered to ensure communication between nodes:

• Network user accounts (initially created during System Platform installation)

• Multiple network interface cards in computers

All Platforms communicate with several attributes on the GR Platform to detect configuration changes. This communication sends NMX heartbeats from each Platform to the GR Platform. For example, the attributes include "time of last deploy," and "time of last configuration change."

In addition to NMX heartbeats, all Bootstraps on each Platform in the Galaxy send each other heartbeats. These heartbeats are for Platform status information, occur every two seconds, and are configurable.
