So the following script worked on Arcpy 32 bit but not on 64 bit IDLE. Any thoughts? 10.6.1 arcgis. 
ALSO - this works against an fgdb but not an enterprise geodatabase (Oracle).
Thanks,
Eric

You likely have a configuration issue with your 64-bit Oracle client.  Make sure both your 32-bit and 64-bit Oracle clients are installed and configured properly.

I don't have an answer but when it comes to cursors, I like to set up a variable for the feature class or table name that you are cursoring through:

fc = r'D:/WOBufferScripts/GLSVDEVL@GLS.sde/GLS.WMO'
arcpy.da.SearchCursor(fc, ['SHAPE@'], "OBJECTID > 0")
That should just about do it....

It was a while ago, but didn't you have to install python for Background Geoprocessing to get 64 bit arcpy?

I have both 32 and 64 bit installed. the results are from each on the same server.

Correct sir! - I had forgotten to put tnsnames in the 64 bit directory
