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. Apply it only to computers that are experiencing this specific problem. This fix may receive additional testing. Therefore, if you are not severely affected by this problem, Microsoft recommends that you wait for the next service pack that contains this hotfix.
