[mapserver-users] MapServer in Visual Studio (C#) not reading Oracle layer after upgrade to 6.4

[Hans Wapenaar (GIS Innovations)]

Oops,

I also found the reason why the dll on a specific location was used. Long
time ago I have added a forced reference to a directory in my source code.
Wanted to make it easy to switch from test server to live server.

Dim strConn as String = "xx/xxx at yyy"
Dim cDir as string = "xxxx"
Dim objlayer As layerObj = myMap.getLayer(il)
If (objlayer.connectiontype = MS_CONNECTION_TYPE.MS_PLUGIN) Then
  objlayer.plugin_library = cDir + "msplugin_oracle.dll"
  objlayer.connection = strConn
End If

Sorry for bothering you.

Hans

Thanks Lars for your suggestions.
Debugging did not give me much more info, but I found the problem:

I still had left an old plugin dll in the directory where also the map file
was stored. Replacing that dll with a new one did the trick. It was also
blocked when I wanted to delete it, so definitely in use by the
webapplication.
A bit strange because I specified a separate directory for the plugin in the
map file.

Anyway, it works now.
Thanks, Hans

Thats a starting point...

Can you enable or raise debugging output for this layer? See [1] for how to
do it.

It should show whether MapServer can connect to the database or if there is
something wrong with the query result.

Best wishes,

Lars
