Hi Travis, hi Mark, I also tried to use extproc.ora instead of configuring listener.ora and the st functions worked for me too. My system is a Windows Server 2008 R2 64bit with Oracle 11.2.0.2 64bit and I used SQL*Plus directly from this machine or from a Windows 7 client with an Oracle 11.2.0.1 32bit client installation. Did you continue your tests ? Do you think that this could be a supported alternative for using the spatial type functions ? Thank you Martin Esri Germany
