Help connecting Oracle Forms/Reports

Hi everyone.

I have Oracle 8i running on Win2k Server in database name MYORACLE under ORA81.

When I installed Oracle Forms, I had to put it under another oracle home
because it wouldn't let me use ORA81.  I called the new home ORARPT.  Now, when
creating a form, what do I enter as the database name ?  It isn't recognizing
MYORACLE.  

Thanks
