Host Names and IP Addresses
vRealize Automation requires that you name the hosts in your installation according to certain
requirements.
n
All vRealize Automation machines in your installation must be able to resolve each other by fully
qualied domain name (FQDN).
While performing the installation, always enter the FQDN when identifying or selecting a machine. Do
not enter IP addresses.
n
In addition to the FQDN requirement, Windows machines that host the Model Manager Web service,
Manager Service, and Microsoft SQL Server database must be able to resolve each other by Windows
Internet Name Service (WINS) name.
Congure your Domain Name System (DNS) to resolve these short WINS host names.
n
Preplan domain and machine naming so that vRealize Automation machines will begin and end with
alphabet (a-z) or digit (0-9) characters, and will only contain alphabet, digit, or hyphen (-) characters.
The underscore character (_) must not appear in the host name or anywhere in the FQDN.
For more information about allowable names, review the host name specications from the Internet
Engineering Task Force. See www.ietf.org.
