Preparing a system for iTX software
Preparing a system for iTX software
Before you install the iTX software modules on their machines, you should ensure the system
meets the requirements that we outline in this section.
Network connection
The machines that are to receive the iTX software modules should be connected to a TCP/IP
network – LAN or WAN – in an arrangement with these characteristics:
• The network and the machines can handle data rates of at least 1000 Mbps.
• All machines are in the same network domain or workgroup.
• None of the machines is connected to the internet.
Ensure all intended users have network user accounts.
Using a DHCP server to allocate an IP address for a Locator Service
machine
The iTX system services, which provide the operating platform for iTX, include an optional
service called the Locator Service. Many iTX systems use this service, even single-domain
systems that use the Discovery model for finding services. Sometimes a system has multiple
Locator Services, for load balancing or multi-domain connections.
Any machine on which a Locator Service runs must have a static IP address. If the iTX network
uses a DHCP server to allocate IP addresses, this server should be set up to provide a static
address for each Locator Service machine.
Locator Service – name resolution
All other system services contact the Locator Service by using its host name, "omn-locator". iTX
translates this host name into an IP address in one of two ways: either by using a WINS or DNS
server, if there is one in the system; or by referring to a local-machine Hosts file.
Important: If you are installing iTX in a system that uses a WINS or DNS server to resolve host
names, you must enter the Locator Service details in the server before starting to install the iTX
software.
To enable iTX to get IP addresses from a Hosts file instead of a DNS server, you enter the IP
address of the Locator Service during the software-installation process. For more information
about Hosts files, see the Help information for a particular machine operating system (e.g.
Windows XP).
