We have the 64-bit Oracle client installed on our ArcGIS Server 10.1 server, but I am still getting an error message in ArcGIS Server when I try to register an Oracle Spatial database connection. The Oracle Spatial database connection works in ArcGIS Desktop 10.1 on my local machine. I am able to bring the table (without geometry) from Oracle Spatial into a map document and join it to a feature class. But I can�??t publish the map document as a map service because the data source (Oracle Spatial) is not registered with ArcGIS Server. The message looks like ArcGIS Server cannot recognize the Oracle client.
The connection property set was missing a required property or the property value was unrecognized. Cannot connect to database because the database client software failed to load. Be sure the database client software is installed and configured correctly.
