## Oracle Database 10g Release 1 (10.1) New Features in Oracle Objects for OLE

- 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.

  See Also: "Installation" "Oracle Objects for OLE Redistributable Files" "Tuning and Customization" for information about the Windows registry subkey
