Chapter 11 Administering DFM (Advanced)
System Administration
DfmBroker DFM Broker maintains a registry about DFM
domain managers, which register the following
information with the broker when its
initialization is complete:
• Application name of the domain manager
• Hostname where the domain manager is
running
• TCP port at which the HTTP server is
listening
When a client needs to connect to the domain
manager, it first connects to the broker to
determine the hostname and TCP port where that
server’s HTTP service is listening. It then
disconnects from the broker and establishes a
connection to the domain manager.
The DfmBroker log file is located at
NMSROOT/objects/smarts/local/logs/brstart.log
