I just reformatted my PC with Win7 64bit to try and take advantage of 64-bit python processing. However I'm not sure what to do here: Our office runs ArcGIS 10.1, TOAD and SDE for Oracle. Toad says I need to install a 64-bit client before I can connect to Oracle. The ArcGIS Resource Center says before I can connect to SDE I need to install a 32-bit oracle client. I am confused.
