shadowd is a daemon that provides background worker threads to migrate data for a shadow

migration. A shadow migration gradually moves data from a source file system into a new “shadow”

file system. Users can access and change their data within the shadow file system while migration is

occurring.

The shadowd service is managed by the service management facility, smf(5). Administrative actions

on this service, such as enabling, disabling, or requesting restart, can be performed using

svcadm(1M). The service's status can be queried using the svcs(1) command.

The svccfg(1M) command can be used to manage the following parameter related to shadowd:

config_params/shadow_threads

Note: Oracle Solaris 11: In this release, you can migrate data from an old file system to a new file

system while simultaneously allowing access and modification of the new file system during the

migration process.

Setting the shadow property on a new ZFS file system triggers the migration of the older data. The

shadow property can be set to migrate data from the local system or a remote system with either of

the following values:

file:///path

nfs://host:path

The host he is trying to connect to (oracle) is not running the required service (ssh).

First the full backup must be restored. This would be the Sunday backup.

Then the last incremental backup must be restored. This would be the Wednesday backup.

Before restoring the Wednesday incremental file system snapshot, the most recent snapshot must

first be rolled back.

By exclusion D) would be best answer even though it is incomplete.

No OpenBoot Environment on the Intel Platform. The Intel environment has no OpenBoot PROM or

NVRAM. On Intel systems, before the kernel is started, the system is controlled by the basic

input/output system (BIOS), the firmware interface on a PC. Therefore, many features provided by

OpenBoot are not available on Intel systems.

Note: The Open Boot PROM (OBP) bootloader only exists within SPARC. Before Solaris 10 01/06, the

bootloader for Solaris x86 was a Sun customized bootstrap software. After Solaris 10 01/06, it uses

GRUB, a well known bootloader that's commonly used in the Linux world.

With GRUB, it's much easier to make the system dual-boot Linux and Solaris. GRUB extends the

capabilities of the bootloader that was not available previously such as the ability to boot from a USB

DVD drive. Those who have used Linux will be quite familiar with GRUB and its options.

Solaris 11 Express makes it pretty easy to set up a local copy of the repository.

A common reason folks need access to a local repository is because their system is not connected to

the Internet.

Tthe pkg set-publisher command can be used to for example add a publisher or to enable or disable

a publisher.

Note: Example Adding a Publisher

Use the -g option to specify the publisher origin URI.

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

Example Specifying the Preferred Publisher

Use the -P option to specify a publisher as the preferred publisher. The specified publisher moves to

the top of the search order. You can specify the -P option when you add a publisher or you can

modify an existing publisher.

# pkg set-publisher -P example.com

Example Enabling or Disabling a Publisher

Use the -d option to disable a publisher. The preferred publisher cannot be disabled. A disabled

publisher is not used in package operations such as list and install. You can modify the properties of a

disabled publishers.

Use the -e option to enable a publisher.

# pkg set-publisher -d example2.com

An image is a location where packages can be installed.

An image can be one of three types:

* Full images are capable of providing a complete system.

* Partial images are linked to a full image (the parent image), but do not provide a complete system

on their own.

* User images contain only relocatable packages.

Check the physical connection.

B: banner

Displays power-on banner.

The PROM displays the system banner. The following example shows a SPARCstation 2 banner. The

banner for your SPARC system may be different.

SPARCstation 2, Type 4 Keyboard

ROM Rev. 2.0, 16MB memory installed, Serial # 289

Ethernet address 8:0:20:d:e2:7b, Host ID: 55000121

C: .version

Displays version and date of the boot PROM.

Note: OBP-OpenBootProm is a firmware which is placed on the sun machine's prom chip.

It is a os independent user interface to deal with the sun machine's hardware components.

The user interface provides one or more commands to display system information.

A: starting with one single character, second character must be letter i, any characters, ending with

letter a.

C: starting with letter e, f, or g, followed by anything.
