The system requirement of AutoCAD Map 3D 2016 (http://knowledge.autodesk.com/support/autocad-map-3d/troubleshooting/caas/sfdcarticles/sfdcarticles/...) has been slightly updated on the part of Oracle Database Specifications – Server.
The original version was:
Database Oracle Database Specifications - Server | Oracle 10g R2 (10.2.0.4.0) Standard Edition, Standard Edition One, or Enterprise Edition Oracle 11g R2 (11.2.0.4.0) Enterprise Edition Oracle 12cR1 (12.1.0.1.0) Enterprise Edition | Oracle 10g or 11g Enterprise Edition is required to support jobs and long transactions. Oracle 11g and Spatial or Oracle 12c and Spatial are required to support 3D. Microsoft® Windows Server® 2008 R2 requires Oracle 11g R2 |
The current version is:
Database Oracle Database Specifications - Server | Oracle® 10g R2 (10.2.0.4.0) Standard Edition, Standard Edition One, or Enterprise Edition Oracle 11g R2 (11.2.0.4.0) Enterprise Edition, Standard Edition Oracle 12cR1 (12.1.0.1.0) Enterprise Edition, Standard Edition | Oracle 10g or 11g Enterprise Edition is required to support jobs and long transactions. Oracle 11g and Spatial or Oracle 12c and Spatial are required to support 3D.
Microsoft® Windows Server® 2008 R2 requires Oracle 11g R2 |
So both Oracle 11g R2 and Oracle 12cR1 have Standard Edition added to the supporting list.
