You can use the pkg set-publisher command to change a publisher URI.

Changing a Publisher Origin URI

To change the origin URI for a publisher, add the new URI and remove the old URI. Use the -g option

to add a new origin URI. Use the -G option to remove the old origin URI.

# pkg set-publisher -g http://pkg.example.com/support \

-G <http://pkg.example.com/release example.com>

Note: You can use either the install or update subcommand to update a package.

The install subcommand installs the package if the package is not already installed in the image. If

you want to be sure to update only packages that are already installed, and not install any new

packages, then use the update subcommand.

B: Configure the AI install server to use a static IP address and default route. D: The create-service command can set up DHCP on the AI install server. If you want to set up a separate DHCP server or configure an existing DHCP server for use with AI. The DHCP server must be able to provide DNS information to the systems to be installed. E: An automated installation of a client over the network consists of the following high-level steps: 1. The client system boots over the network and gets its network configuration and the location of the install server from the DHCP server. 2. The install server provides a boot image to the client. 3. Characteristics of the client determine which installation instructions and which system configuration instructions are used to install the client. 4. The Oracle Solaris 11 OS is installed on the client, pulling packages from the package repository specified by the installation instructions in the AI install service. G: Install the AI tool set. Use the installadm create-service command to create an AI install service. Give the service a meaningful name, and specify the path where you want the service created. Specify the source of the network boot image (net image) package or ISO file. installadm create-service [-n svcname] [-s FMRI_or_ISO] [-d imagepath] -d imagepath The imagepath is the location of the new install service. The install-image/solaris-auto- install package is installed to this location, or the specified ISO file is expanded at this location.

A: ZFS encryption was introduced in ZFS Pool Version Number 30, Solaris Nevada b149.

Filesystem encryption since Solaris 11 Express

B: Deduplication was introduced in ZFS Pool Version Number 21, Solaris Nevada b128.

E: Booting From a ZFS Root File System

Both SPARC based and x86 based systems use the new style of booting with a boot archive, which is a

file system image that contains the files required for booting. When a system is booted from a ZFS

root file system, the path names of both the boot archive and the kernel file are resolved in the root

file system that is selected for booting.

The following options are supported:

-C

Connects to the zone console. Connects to the zone console.

Note:

After you install a zone, you must log in to the zone to complete its application environment. You

might log in to the zone to perform administrative tasks as well. Unless the -C option is used to

connect to the zone console, logging in to a zone using zlogin starts a new task. A task cannot span

two zones

Incorrect answers:

B: No option -console.

C, D: No option -z.

Etherstubs are pseudo ethernet NICs which are managed by the system administrator. You can create

VNICs over etherstubs instead of over physical links. VNICs over an etherstub become independent

of the physical NICs in the system. With etherstubs, you can construct a private virtual network that

is isolated both from the other virtual networks in the system and from the external network. For

example, you want to create a network environment whose access is limited only to your company

developers than to the network at large. Etherstubs can be used to create such an environment.

Note: Oracle Solaris 11 introduces a new and powerful network stack architecture which includes:

* Networking virtualization with virtual network interface cards (VNICs) and virtual switching

(etherstubs)

* Tight integration with zones

* Network resource management - efficient and easy to manage integrated quality of service (QoS)

to enforce bandwidth limit on VNICs and traffic flows

Components of Network Virtualization in Oracle Solaris

A: ZFS can automatically share file systems by setting the sharenfs property. Using this property, you

do not have to modify the /etc/dfs/dfstab file when a new file system is shared. The sharenfs

property is a comma-separated list of options to pass to the share command. The value on is an alias

for the default share options, which provides read/write permissions to anyone. The value off

indicates that the file system is not managed by ZFS and can be shared through traditional means,

such as the /etc/dfs/dfstab file. All file systems whose sharenfs property is not off are shared during

boot.

Incorrect answers:

D: A share can define options for both NFS and SMB sharing.

B: The Network Status notification icon is only displayed on the desktop if you are using NWAM to

automatically configure your network.

C: All online (Wireless)

Indicates all manually enabled connections in the enabled network profile are online and that the

required number of connections in the enabled profile group (if such a group exists) are online. The

required number is the same as those described for the All online (Wired) status.

Note that at least one online connection is wireless.

the Status of Your Network Connection

B: Set the correct permissions. Serving a Local Repository Using SMF First, create a ZFS file system to hold the repository. Next, make a local copy of the IPS repository file. Make the contents of the repository file available to the pkg.depotd(1M) server, using the lofiadm command to mount the ISO image. 4. (A) Copy the repository files to the ZFS file system you created. This will increase the performance of repository accesses and avoid the need to remount the .iso image each time the system restarts. (Be sure to use /mnt/repo, not /mnt/repo/, so that you copy the repo directory and not just the files and subdirectories in the repo directory.) # rsync -aP /mnt/repo /export/repo2010_11 You can use the df command to confirm the copy: 5. Once the files are copied, unmount the image and deallocate the block device. 6. Now that your local copy is ready, use the svccfg command to configure the repository server service, specifying the location of your local repository and setting readonly to true: (D)# svccfg -s application/pkg/server setprop pkg/inst_root=/export/repo2010_11/repo (E)# svccfg -s application/pkg/server setprop pkg/readonly=true 7. Start the pkg.depotd repository service: (G) # svcadm refresh application/pkg/server (I) # svcadm enable application/pkg/server Reference: How I Created Local Package Repositories http://www.oracle.com/technetwork/articles/servers-storage-admin/localrepositories1377242.html

Decompress using savecore -f vmdump.0

savecore - save a crash dump of the operating system

-f dumpfile

Attempt to save a crash dump from the speci-

fied file instead of from the system's

current dump device. This option may be use-

ful if the information stored on the dump

device has been copied to an on-disk file by

means of the dd(1M) command.
