Dear forum users,
I came across this document "SRSS-4.1 Installation and Configuration
Guide for the Solaris OS" and on page 45, it stated about headless
SunRay server and a file called Xservers.SUNWut.prototype. I have few
doubts regarding this;
1) My SunRay servers doesn't have a graphic card. Do the headless
setting is Mandatory for me?
It depends.
Even if you server has no conventional graphics card, it may have a
service processor, which provides a remote graphical console. In that
case your server is effectively not headless.
The reason for this setting is that the dtlogin display manager, which
is needed for managing Sun Ray displays may fail trying to start a
graphical session on non-existent hardware. Some recent versions of the
display manager may be resilient against this condition and not fail
when the can't start a configured console display. If that is the case,
you don't need the settings.
2) What if i don't set the headless setting, would it going to impact my
DTUs?
If it causes a problem, it will impact the server-side services, in
particular the display manager. You'll notice that right away, as your
DTUs will be stuck without a session, showing OSD code 26 instead.
If everything works without this change you should be fine, but if the
server doesn't work for you, you should apply the change.
3) What other problem i will encountered if not set headless?
See above
