[mapguide-users] Retrieving data from Oracle for MapGuide OS

Hi Everyone,

I am a GIS student currently working on a MapGuide OS web mapping project
for a real estate company. I am currently working on a connection setup to
the Oracle Database. The Oracle database is located on another server, and I
have both OracleInstantClient and the corresponding ODBC driver installed on
my local workstation (the one that holds the MapGuide Server). 

On the Oracle side, I have non-spatial data where I have normal data with
two extra columns that hold the lat/long values, the DBA has created a VIEW
for my user account to access and retrieve data. Knowing that I will have to
define x,y within Maestro, I decided to use the ODBC FDO connection instead
of the King Oracle. I first setup a System/User DSN for the Oracle
Connection with connection tested without problems. Then I defined a new
data connection in Maestro 2.0 using ODBC FDO with DSN connection. The
connection was tested within Maestro without any problems reported. 

I then proceed to Configure Column within Maestro, where I waited for 1-2
min and Maestro returned an error saying Resource is busy. I tried
connecting to the Database through OpenOffice Base using the same ODBC
connection and although I was not able to see the VIEW, I was able to see
the other tables no problem. 

My question is, is there any additional settings that I have to define
within Maestro? Such as the ConnectionString? currently, my ConnectionString
is empty (I only enter information for userid, password, and DataSourceName.
I assume if OpenOffice Base was able to connect and retrieve those table,
then Maestro should have no problem in reading those tables as well. 

Any help will be appreciated!!
