In this recipe, we will check the operating system's (OS) requirements, including the OS packages that are required for the progress of the OEM installation.
Before you start, ensure that the server is connected to the network, and an SSH or a telnet client is available. Also, make sure you have access to the Unix server as a root user or as a privileged user.
Perform the following steps to check the operating system's requirements as a root or as a privileged user with root privileges:
Install the Oracle validated package.
