-------------------------------------------------------------------------------
The information in this article applies to:

- Microsoft ODBC for Oracle version 2.5 Build 2.573.2927 
- Microsoft OLE DB Provider for Oracle, version 2.0 
- Microsoft Data Access Components version 2.0 
-------------------------------------------------------------------------------

SYMPTOMS
========

Both the Microsoft ODBC Driver for Oracle, version 2.573.2927, and the Microsoft
OLE DB Provider for Oracle, version 2.0.3002.15, shipping with the Microsoft
Data Access Components (MDAC) version 2.0 have handle leaks, which lead to
memory leaks. MDAC version 2.0 components are included both in the Data Access
2.0 Software Development Kit (SDK) as well as Visual Studio version 6.0.



CAUSE
=====

Microsoft has confirmed this to be a problem in the Microsoft products listed at
the beginning of this article.


RESOLUTION
==========

The Oracle ODBC Driver, version 2.573.2927, and the Oracle OLE DB Provider,
version 2.0.3002.15, were both fixed with the release of the MDAC version 2.1
components. Please install MDAC version 2.1 if you are experiencing the handle
leak. If you cannot upgrade to MDAC version 2.1 you can still install the ODBC
Driver fix mentioned in this article. You must upgrade to MDAC version 2.1 if
you are using the OLE DB Provider for Oracle.

The fix contains a patched version of the Microsoft Oracle ODBC Driver. At this
time, it does not contain a patched version of the Oracle OLE DB Provider.

A supported fix is now available from Microsoft, but it is only intended to
correct the problem that is described in this article. Only apply it to systems

testing. Therefore, if you are not severely affected by this problem, Microsoft
