FIX: Handle Leak in ODBC Driver/OLE DB Provider (194387)


The information in this article applies to:

  • Microsoft ODBC for Oracle version 2.5 Build 2.573.2927
  • Microsoft OLE DB Provider for Oracle 2.0
  • Microsoft Data Access Components 2.0
This article was previously published under Q194387

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.
