3.4 Identifying Software Requirements

Depending on the products that you intend to install, verify that the required operating system software is installed on each node of your cluster.

Requirements listed in this document are current as of the date listed on the title page. To obtain the most current information about operating system requirements, see the online version in the Oracle Help Center at the following URL:

OUI performs checks on your system to verify that it meets the listed operating system requirements. To ensure that these checks complete successfully, verify the requirements before you start OUI.

Note:

Oracle does not support running different operating system versions on cluster members, unless an operating system is being upgraded. You cannot run different operating system version binaries on members of the same cluster, even if each operating system is supported.
