Installing Oracle Linux - Expert Consolidation in Oracle Database 12c - page 144

This network configuration utility uses Network Manager under the covers. Network Manager is the replacement
for the network administration tool (“ system-config-network ”) and one of the bigger changes in Oracle Linux 6 over
its previous versions. This does not imply that the way network settings were configured in Oracle Linux go away, but
you should be aware of the new way of doing things. The system settings for the selected device can be chosen in the
tabs “wired,” “802.x Security,” “IPv4 Settings,” and “IPv6 Settings.” You have the option to make the following changes
on these tabs:

Wired : On this tab you can define the Media Access Control (MAC) address for a specific
interface. It is suggested to leave this value blank to use the MAC address of the interface.
The MAC address is important when booting-should the network interface card (NIC)
return a different MAC address than defined (which can happen during cloning of virtual
machines) the network interface will default to a DHCP address and discard its static
configuration if used.

802.1x Security : In this tab you can define 802.1.x port-based network access control (PNAC).
Normally you would not need to enable 802.1x security-when in doubt leave this option
unchecked.

IPv4 Settings : Although the days of the “old” Internet addressing scheme, IPv4 are
numbered, it is still the most important way of connecting servers to the local network
for the foreseeable future. Therefore the IPv4 protocol plays the most important role in
connecting a server within the network. As with the network administration tool you can
define the network to be dynamically configured using the dynamic host configuration
protocol (DHCP), or manually configured. Most users will probably choose a static
configuration by supplying an IP address, netmask, and gateway. Additionally DNS servers
can be specified for naming resolution as well as a search domain to be appended in the
absence of a FQDN. If necessary you can even set up static routes by clicking the “Routes…”
button.

IPv6 Settings : Despite several global IPv6 awareness days there has not been a breakthrough
in adoption of the next generation IP protocol inside organizations.
Most users therefore will choose to disable IPv6 here (“Method: ignore”).

Time zone settings and root password
Following the network configuration you need to set the system's time zone. This setting is important as it allows
determining the location of the server. If you are planning on clustering the Oracle system yet to be installed then
please ensure that all the cluster nodes share the same time zone.
To pick a time zone you can either use the zoom controls to click on the city depicted by a yellow dot on the map
nearest to your location to set the time zone. Another option is to use the dropdown list to find the most appropriate
time zone.

■ The documentation states certain implications when dual-booting your Oracle Linux installation with Windows.
a production oracle database server however is not likely to be dual-booted with a non-unIx operating system.

Note

Before finally making it to the partitioning wizard, you need to set a secure root password to be used with this
server. As always, only system administrators should have access to the root account. Click “Next” to proceed with the
installation.
