It's gone ...
There isn't a public Sample App anymore, it's quite some time already
The 2 options you have are:
a) run your own Sample App: OBIEE Samples
b) get a trial account on Oracle Cloud and start an OAC instance and for 30 days you will have an online environment you can start when needed
There isn't any sign so far that something like the old public Sample App will be back, everything point to the opposite thing ....
You beat me to the post on this one...
Beaten by the other two gents ;-)
OK...that is what I was afraid of. That is sad...it really gave us all a way to sometimes collaborate on things.
Oh well, it was nice when we had it.
Thanks everyone for your input!
