JES installation and deployment MUST have a domain?

Hi All , a project will be deployed in an organisation.It's contain : Web server , Access manager, directory server ,and portal. My question is should I have to prepare a sub-domain for it? such as

abc.example.com .the organisation's domain is example.com.

or the other way: just use the top domain's DNS server (example.com) make the resolve to these machines' IP.Can it work?

will the access manager 's sso work without its own DNS server ?

is there any document indicate these infomation ?

Thanks for any help.

Not sure if this helps - but I assume you are talking about the requirement for a domain name causing some probs on a dev machine?

I had this same problem - and basically made up one and put it in my hosts file so it would accept it at the time.

For example - in my hosts file I would put:

dev.vaiism.com192.168.1.14

(the ip being that of the one in my local lan)

I could then get by with having this set either in the DNS of my domain (having dev pointing to the internal lan) - or setting in hosts of any other machines accessing it.

Not sure if this is what you were looking for tho. Hope that helps.

Make sure that there is an entry in the /etc/hosts file. The format would be<ipaddress> <hostname.domainname>You wouldnt require to set up an subdomain name for configuration of any of the components in JES stack if your /etc/hosts file is in good shape.
