You want to change the host name of the servers on which you install TREX. You can do this for the following cases:
To make your TREX installation accessible by a virtual host name you rename the host name of the host on which you intend to install TREX.
You change the TREX host name for a TREX single-host installation on the host where TREX has been installed.
You change the TREX host name for a TREX multiple-host installation on each host in your distributed TREX landscape where TREX has been installed and configured. You change the host name on one TREX host first and repeat the same procedure for the other hosts that you want to rename.
Prerequisites
The new host name must be valid at the operating system level. It can be a new primary host name, an additional alias name, or it's IP address. The host must be accessible with this name using theping command. In a distributed TREX landscape (multiple-host-Installation) the host must be accessible with this name using theping command from all other hosts as well.
