represents the host name of the master gateway node and the Administrator tool port number.
You configure the Administrator tool port when you define the domain. You can define the domain during installation or by running the
infasetup
DefineDomain command line program. If you enter the domain port instead of the Administrator tool port in the URL, the browser is directed to the Administrator tool port.
If the domain fails over to a different master gateway node, the host name in the Administrator tool URL is equal to the host name of the elected master gateway node.
