New Patch Set Updates (PSUs) are no longer released for this version. Security vulnerabilities may not be patched by Oracle.

Released for Windows in April 2010, 11gR2 (11.2.0.1) brought a suite of performance and availability enhancements. For users on 32-bit Windows platforms—which include older versions like Windows XP, Windows 7, and Windows Server 2008—this release provided a bridge between traditional on-premise management and modern automated features.

Older 32-bit applications and third-party tools often require the 32-bit Oracle client or engine to maintain driver compatibility (ODBC/OLE DB).
