Applies to:

Oracle Database - Enterprise Edition - Version to [Release 11.2]

Oracle ARP protocol driver installation is recommended as per

For 11.2, the Oracle ARP protocol driver is not installed during Oracle Grid Infrastructure Installation.  Install the oraarpdrv post-GI installation as per Oracle® Database Release Notes 11g Release 2 (11.2) for Microsoft Windows.
