Do I also need to install Oracle HTTP Server with Oracle Forms and Reports Standalone?No, it's included.
How would my users access the application.From browser, of course, for example http://machine_name:port/forms/frmservlet?config=<application>
I have got 1000 users (50 concurrent) users, which will be using forms and reports services. Should I install forms service and reports services on separate machines?I normally use two machines with everything on them, and running in load balancing via Web Cache.
I am calling reports from forms, so how would I configure that?In what sense ? do you mean how to call reports from forms ?
My both machines have 4 GB of RAM, and I am running Redhat Linux AS 4 32 bit. Will that be enough for my users?For 50 concurrent users, yes.
