The fully qualified hostname for the application server is the address at which Controller UI users and application agents will use to access the Controller. You specify this hostname when you install the Controller. The hostname needs to be in the /etc/hosts file on the machine.

The following example shows an entry in /etc/hosts with the IP 21.43.65.987, the fully qualified hostname application1.mycompany.com and the alias app1:

21.43.65.987 application1.mycompany.com app1
