Is a fully qualified host name (FQHN) mandatory for OAS/OBIEE Installation?

Question

I am about to install OAS 5.5. I've installed OBIEE many times, so I am familiar with the installation process. This time, I was planning to install OAS with short host names. Reason being, I want to clone the LINUX VMs (let's call this development) once all components are installed and operational, as to avoid repeating the installations for the subsequent production environment. Both environments will be on separate closed networks in different physical locations, so I don't have to be concerned with clashing/conflicting host names or I.P. addresses. The installation manual contains the following statement:

Before you install Oracle Analytics Server, you must make sure that the EndPoint URLs resolves to a FQDN or you use the Frontend Load Balancer for server-side configuration.

You must configure the front-end host with a FQDN.

Is this clearly stating that I must install OAS using fully qualified host names? My environments will contain a single BI instance. Am I missing something here?

Thanks in advance

I also thought that as long as the hosts resolve in /etc/hosts, I should be able to install with short names. I'll give it a go.

Thanks for your input.

We install vm's, containers and appliances all the time against an internal IP and virtual hostname (i.e. 12.7.0.0.1 dev.xxx.xxx dev) and move them around and access with external IP|hostname that is configured in the network DNS

We resolve in /etc/hosts

You may remember the Enterprise Deployment Guide utilizes VIPs and VHNs

The wording just means your installation needs to be reachable.

I not endorsing it as a production solution; merely stating it is possible. Also, you can change the endpoints after the fact.

Other comments welcomed.
