Interfaces that are on the IP layer (Layer 3) are configured by using the ipadm command.

Storage

ZFS is the root file system on Oracle Solaris 11 offering a superior experience in terms of

manageability, scalability and data integrity. ZFS presents a pooled storage model that completely

eliminates the concept of volumes and the associated problems of partitions, provisioning, wasted

bandwidth and stranded storage. Thousands of file systems can draw from a common storage pool,

each one consuming only as much space as it actually needs. All operations are copy-on-write

transactions ensuring that the on-disk state is always valid.

Incorrect:

Not A: Network Auto-Magic (NWAM) is a project to simplify and automate network configuration on

Solaris. Network Auto-Magic generally refers to Network Profiles, which allow users to specify

various network configurations to be created depending on the current network conditions. The

Service Discovery project, which incorporates Multicast DNS into Solaris, also fell under the Network

Auto-Magic umbrella.

Not B: Pre-Flight Checker tool which can be used to check whether apps will work without

modification on Solaris 11

Not C: Network Auto-Magic is a project to simplify and automate network configuration on Solaris.

Oracle Cloud Infrastructure

Overview

* Flexible cloud infrastructure supports dynamic resource pooling, elastic scalability, and rapid

application deployment

* Includes Oracle Enterprise Manager, a complete cloud lifecycle management solution that allows

you to quickly set up, manage, and support enterprise clouds and traditional Oracle IT environments

from applications to disk

* Built-in security and high availability

* Application-aware virtualization and management capabilities

Note:

* In many cases, one software package depends on another package. For example, one package

might require functionality that is in a second package in order to function or install correctly. These

relationships, or dependencies, between packages are important for automating package installation

operations and for upgrading system software to known and well-tested states. IPS supports a

number of different relationships between packages.

Incorrect:

Not B: IPS relies on network-accessible or locally available software repositories as a delivery

mechanism.

TFTP Error or System Hangs After GATEWAY Message

The DHCP server provides an IP address and a location of the initial boot program as part of the

DHCP response.

If the boot program does not exist, then the AI client boot cannot proceed. The following message is

displayed:

Through the zonecfg utility, the file-mac-profile can be set to one of the following values (see note

below). All of the profiles except none will cause the /var/pkg directory and its contents to be read-

only from inside the zone.

* none

Standard, read-write, non-global zone, with no additional protection beyond the existing zones

boundaries. Setting the value to none is equivalent to not setting file-mac-profile property.

* strict

* fixed-configuration

Permits updates to /var/* directories, with the exception of directories that contain system

configuration components.

IPS packages, including new packages, cannot be installed.

Persistently enabled SMF services are fixed.

SMF manifests cannot be added from the default locations.

Logging and auditing configuration files can be local. syslog and audit configuration are fixed.

* flexible-configuration

Note:

zonecfg file-mac-profile Property

By default, the zonecfg file-mac-profile property is not set in a non-global zone. A zone is configured

to have a writable root dataset.

In a solaris read-only zone, the file-mac-profile property is used to configure a read-only zone root. A

read—only root restricts access to the runtime environment from inside the zone.

Resource Management

You can use the beadm utility to create and manage snapshots and clones of your boot

environments.

Note: The following distinctions relevant to boot environment administration:

A snapshot is a read-only image of a dataset or boot environment at a given point in time. A

snapshot is not bootable.

A boot environment is a bootable Oracle Solaris environment, consisting of a root dataset and,

optionally, other datasets mounted underneath it. Exactly one boot environment can be active at a

time.

A clone of a boot environment is created by copying another boot environment. A clone is bootable.

Reference: Managing Boot Environments With Oracle Solaris 11 Express, Using beadm Utility

Note:

* Modern computing environments have to provide a flexible response to the varying workloads that

are generated by different applications on a system. A workload is an aggregation of all processes of

an application or group of applications. If resource management features are not used, the Oracle

Solaris operating system responds to workload demands by adapting to new application requests

dynamically. This default response generally means that all activity on the system is given equal

access to resources.

A snapshot is a read-only point-in-time copy of a file system. The copy-on-write design

of ZFS makes them essentially “free” - They are space efficient and instantaneous, providing an

invaluable part of backup strategies and synchronizing data between systems.

Incorrect:

Incorrect:

Not A: A ZFS vdev (aka "virtual device") is either:

a single disk, or

two or more disks that are mirrored, or

a group of disks that are organized using RAID-Z.

There are also special kinds of vdevs like hot-spares, ZIL or cache devices, etc.

Not D:

Clones are writeable snapshots, ideal for storing many private

copies of shared data for operations such as data migration, test

and development, or backup.

B: The disk intended for the root pool must have an SMI label. Otherwise, the installation will fail.

D: The default target location for the installation is the first disk found on each client that meets the

size requirement. If the size of a disk is greater than or equal to the recommended size, the installer

selects that disk as the installation target. If the size of the disk is less than the recommended size,

the installer checks the next disk. If no disk is found that meets the size requirement, the automated

installation fails for that client.

Note:

* If you do not specify a target location on a client for installing the Oracle Solaris OS, AI selects a

default target.

Incorrect:

not A: and – Optional. You can use AI to configure swap and dump during the

automated install.

Not C: A mirrored dataset for the root pool is not required.

Reference: Oracle Solaris ZFS Administration Guide, Installing a ZFS Root Pool

B:

* With Oracle Solaris 11, the configuration of the system is specified as a set of configuration

parameters provided in a file called the System Configuration Profile, which is in the form of an SMF

profile.

* Oracle Solaris 11 uses SMF for configuration. SMF uses a database to centralize the configuration

information, it uses the SMF framework to carry out configuration tasks, and it uses SMF properties

as an API. SMF is also well integrated with Oracle Solaris Zones technology.

* Oracle Solaris 11 uses the Service Management Facility (SMF) to centralize configuration

information. The new sysconfig command replaces the older sys-unconfig command and provides a

method based upon SMF for unconfiguring an Oracle Solaris 11 instance and reconfiguring it.

D: To use AI to install client systems over the network, you must set up DHCP and set up an AI service

on an AI server.

An AI service is associated with a SPARC or x86 AI install image and one or more sets of installation

instructions.

Note:

Using the Oracle Solaris Automated Installer (AI) you can create and manage services to install the

Oracle Solaris 11 operating system over the network in a hands-off manner.

Three significant steps are performed by various services during the installation process:

Assigning a network identity for the system being installed

Contacting the automated installation service to download over the network a small boot image and

a description of how to provision a system

Provisioning the system over the network, including software and system configuration

Each of the steps can be performed by various services residing on the same physical or virtual

system, or the services can be on separate systems. In this article, the following services reside on

the same system:

DHCP service

Automated Installer service

Image Packaging System (IPS) repository service

Running a Custom Script During First Boot

To perform any additional installation or configuration that cannot be done in the AI manifest or in a

system configuration profile, you can create a script that is executed at first boot by a run-once SMF

service.

1. Create the first-boot script.

2. Create the manifest for an SMF service that runs once at first boot and executes the script.

3. Create an IPS package that contains the service manifest and the script.

4. Add the package to an IPS package repository.

5. Install that package during the AI installation by specifying that package in the AI manifest.

The service runs and executes the script at first reboot after the AI installation.

Reference: Installing Oracle Solaris 11 Systems, Running a Custom Script During First Boot

Boot Load Failed

If the AI client starts downloading the boot_archive, but then fails with the error, “Boot load failed,”

that indicates that the client DHCP information is configured incorrectly.

Rebooting with command: boot net:dhcp - install

Boot device: /pci@7c0/pci@0/network@4:dhcp File and args:

1000 Mbps FDX Link up

HTTP: Bad Response: 500 Internal Server Error

Evaluating:

Boot load failed

This error could happen if another DHCP server is responding to the client. Check the DHCP

configuration for this client. If the configuration appears to be correct, determine whether there is

another DHCP server in the subnet.

The routeadm command is used to administer system-wide configuration for IP forwarding and

routing. IP forwarding is the passing of IP packets from one network to another; IP routing is the use

of a routing protocol to determine routes.

-e option...

Enable the specified option. The effect is to prepare the associated services (svc:/network/ipv4-

forwarding:default in the case of ipv4-forwarding) for enabling. By means of the routing-svcs

variable, the routing daemons are specified to be enabled on subsequent boot or when routeadm -u

is run.

-d option...

Disable the specified option. The effect is to prepare the associated services (svc:/network/ipv4-

forwarding:default in the case of ipv4-forwarding) for enabling. By means of the routing-svcs

variable, the routing daemons are specified to be disabled on subsequent boot or when routeadm -u

is run.

How to Use DTrace in a Non-global Zone

1. Use the zonecfg limitpriv property to add the dtrace_proc and dtrace_user privileges.

global# zonecfg -z my-zone

zonecfg:my-zone> set limitpriv="default,dtrace_proc,dtrace_user"

zonecfg:my-zone> exit

Note –

Depending on your requirements, you can add either privilege, or both privileges.

2. Boot the zone.

3. global# zoneadm -z my-zone boot

Log in to the zone.

global# zlogin my-zone

4. Run the DTrace program.

my-zone# dtrace -l

Note:

* Oracle Solaris DTrace is a comprehensive, advanced tracing tool for troubleshooting systemic

problems in real time.

* DTrace helps you understand a software system by enabling you to dynamically modify the

operating system kernel and user processes to record additional data that you specify at locations of

interest, called probes.
