Documentation for Oracle Objects for OLE was improved and reorganized, although there is no additional content. The documentation was reformatted to a printable, PDF format. PDF and HTML are provided in the Documentation Library. Online Help in WinHelp format is no longer provided.
Support for Oracle Grid Computing
Oracle Objects for OLE is grid-enabled, allowing developers to take advantage of Oracle database grid support without having to make changes to their application code.
Support for New Data Types
Oracle Objects for OLE provides support for the BINARY_DOUBLE and BINARY_FLOAT data types introduced in Oracle Database 10g. Instances of these types can be fetched from the database or passed as input or output variables to SQL statements and PL/SQL locks, including stored procedures and functions.
The following constants were added in the oraconst.txt to bind the BINARY_DOUBLE and BINARY_FLOAT data types.
ORATYPE_BDOUBLE, Oracle data type BINARY_DOUBLE, value 101
ORATYPE_BFLOAT, Oracle data type BINARY_FLOAT, value 100
Support for Multiple Oracle Homes
Oracle Objects for OLE can be installed in multiple Oracle homes, starting with release 10.1. However, being a Component Object Model (COM) component, only one instance can be active on the computer. This means that the current (latest) installation renders the previous one inactive.
To make multiple Oracle homes available, the use of a KEY_HOMENAME is required. Also, some of the Oracle Objects for OLE files include a version number.
