Restrictions of Oracle Schemas
When you create an Oracle schema, the following restrictions apply:
A
feature class (page 2063) must define or inherit at least one identity property
(page 2071).
You cannot add a non-nullable data property to a class that already has
data.
Identity properties cannot be nullable.
Read-only identity properties must be auto-generated.
The length for string properties must be between 1 byte and 4000 bytes,
inclusive.
For decimal properties, precision must be between 1 and 38, inclusive, and
scale must be between -84 and 127, inclusive.
A feature class can have multiple geometric properties. Although it is not
mandatory, having a main geometry as an attribute of the feature class
can help you to identify which geometry property to use as the default for
queries and rendering. Both HasMeasure and HasElevation are supported.
Version Enabling
The Autodesk FDO Provider for Oracle included with AutoCAD Map 3D 2011
creates tables in the FDO data store (page 2059) that are not automatically
version-enabled. Therefore, when you create a new Oracle data store using
the default options, the resulting table is not version-enabled, so persistent
locking
(page 2070) and long transaction (page 2067) are not supported. (This differs
from previous releases.)
Oracle Workspace Manager (OWM) is used for versioning and persistent
locking support.
NOTE Versioning and persistent locking are not available with the Oracle XE
version.
