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.

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.
