High Availability Log Messages

The
dxserver.log
file of each node in the network contains certain messages indicating that
dx-configuration.properties
file is configured properly.
If dx-configuration.properties under
Data Integration Hub
server is configured properly the following messages (order may vary a bit) should be seen in dxserver.log of each node. In this example there are two hosts called host1 and host2 and the ports are
Data Integration Hub
default ports.
