Identify the two kernels that are shipped with Oracle Linux 6.
Oracle Linux 6 ships with two sets of kernel packages:
* Unbreakable Enterprise Kernel [kernel-uek-2.6.32-100.28.5.el6]
Only available on the x86_64 (64 bit) platform
Installed and booted by default
* Red Hat compatible Kernel [kernel-2.6.32-71.el6]
Installed by default
You have mounted an Oracle Linux 6 ISO image (v33411-01.iso) on your system in the /mnt/iso/OL6u3/Server directory. You want to use this image in your local yum repository configuration file and enable it. Which yum repository configuration file has the correct entries to use this image as a local repository?
The DBA tells you that the system is not overloaded but you can tell that the system us actively swapping. What command would you run to show this information to the DBA?
Which two commands can be used on Oracle Linux to find the routing table and default gateway information of your network?
A: netstat - Print network connections, routing tables, interface statistics, masquerade connections, and multicast memberships
D:
* route - show / manipulate the IP routing table
* route --n
-n
show numerical addresses instead of trying to determine symbolic host names. This is useful if you are trying to determine why the route to your nameserver has vanished.
* The output of the kernel routing table is organized in the following
columns
Destination
The destination network or destination host.
Gateway
The gateway address or '*' if none set.
Genmask
The netmask for the destination net; '255.255.255.255' for a
host destination and '0.0.0.0' for the default route.
Incorrect:
Not B: use route --n. No subcommand show.
Not E: traceroute - print the route packets trace to network host
Examine the output of the yum.conf configuration file from o Oracle Linux 6 server.
What does the ''installonly_limit=3'' option mean?
installonly_limit
Number of packages listed in installonlypkgs to keep installed at the same time. Setting to 0 disables this feature. Default is '3'. Note that this functionality used to be in the 'installonlyn' plugin, where this option was altered via. tokeep. Note that as of version 3.2.24, yum will now look in the yumdb for a installonly attribute on installed packages. If that attribute is 'keep', then they will never be removed.
