Because general support has ended, Oracle no longer offers 11.2.0.4 for public download on its free Technology Network (OTN). This version is now part of Oracle's legacy software archive. Access to the 11.2.0.4 patch set typically requires a valid Oracle Support contract to download it from the Oracle Software Delivery Cloud or My Oracle Support (MOS).
