<p class=MsoNormal><span style='font-size:10.0pt;font-family:"Times New Roman","serif"'>I
am working on a FDO based application that should use the King Oracle Provider
to connect to a data source on an Oracle 11g instance. The application
currently connects fine to an empty data store (the data store does not contain
any tables) and successfully applies a test schema that consists of a feature
and a non feature class. The problem arises in the following step where a
describe schema request is executed. In this case, the result is one schema
named <i>KingOra</i> and no classes. I expected the test schema and its
corresponding classes being reported.<o:p></o:p></span></p>

<p class=MsoNormal><span style='font-size:10.0pt;font-family:"Times New Roman","serif"'>The
application has access to all the DLLs that come with FDO. The DLLs were
created by compiling the projects from the trunk in release mode. Due to the
fact that I use MS Visual Studio C++ 2008 Express Edition, I had to open each
solution and compile it separately as some of the projects referenced MFC files
that are not available with the Express Edition. Those issues were corrected in
the shadow and all builds succeeded. <o:p></o:p></span></p>

<p class=MsoNormal><span style='font-size:10.0pt;font-family:"Times New Roman","serif"'>Besides
the changes to eliminate MFC references, one additional change was required in
the King Oracle provider project in that the references to Oracle 10 libs were
replaced by the corresponding Oracle 11 ones. <o:p></o:p></span></p>

folder and hence made accessible to the FDO application.<o:p></o:p></span></p>

<p class=MsoNormal><span style='font-size:10.0pt;font-family:"Times New Roman","serif"'>I
did perform some debugging on the code. When following the statement that
retrieves the schema name (see code below), I noted that it does not hit the
function that implements the retrieval of the schema name but ends up in the
function <i>FdoCollection::GetCount()</i> (file <i>FDO\Unmanaged\Inc\Common\Collection.h</i>).
However, following other requests like the apply schema execute or the describe
schema execute call, the correct functions are hit and executed. I also did
some dependency checks on some DLLs and executables and nothing missing was
reported.<o:p></o:p></span></p>

<p class=MsoNormal><span style='font-size:10.0pt;font-family:"Times New Roman","serif"'>I
assume that this may be just a simple setup issue but after trying multiple things
now, I reached a point where I am not sure what to try next. If someone has any
suggestions I would appreciate the feedback. Also, if there are additional
questions, please let me know.<o:p></o:p></span></p>
