[mapguide-users] Oracle Spatial v/s Oracle Locator with MapGuide FDO

[Joel Carranza]

Simon, 

I wonder if you could follow up a little bit on your statement:

"Oracle provider ... require(s) the F_* Autodesk catalog tables (which the
AutoDesk provider  
shipped with their per pay version...)"

I was not aware of this. It would explain alot about why we can't get
anything to work. Is this an explicit fact or simply an impression you got
after trying to get things to work? Can you point me to some documentation?

Thanks
Joel
