- Image Packaging System content retrieval utility

Options include:

-c cache_dir

The path to a directory that will be used to cache downloaded content. If this directory is not supplied, the client automatically selects a cache directory. In the case where a download is interrupted, and a cache directory was automatically chosen, use this option to resume the download. See the “Environment Variables” section below for details about how to set the location used for temporary data storage.

How to Use DTracein a Non-global Zone

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.

Boot the zone.

global# zoneadm -z my-zone boot

Log in to the zone.

global# zlogin my-zone

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.

Note:

*sendmail

*Enabling Access to Remote Clients

On an unmodified system, access to sendmail by remote clients is enabled and disabled through the service management facility (see smf(5)). In particular, remote access is determined by the value of the local_only SMF property:

svc:/network/smtp:sendmail/config/local_only = true

A setting of true, as above, disallows remote access; false allows remote access. The default value is true.

The following example shows the sequence of SMF commands used to enable sendmail to allow access to remote systems:

# svccfg -s svc:/network/smtp:sendmail setprop config/local_only = false

# svcadm refresh svc:/network/smtp:sendmail

# svcadm restart svc:/network/smtp:sendmail

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

A:Joint innovations, co-engineered projects, and specific optimizations make Oracle Solaris 11 the best UNIX for your Oracle Database, Oracle Fusion Middleware, and Oracle Applications.

C:Oracle Solaris and SPARC with Oracle Database, Oracle Fusion Middleware, Java, and Oracle Applications hold many world-record benchmarks

Not D: Solaris 11 is available for x86 as well.

No DHCP or Proxy DHCP Offers Were Received

If a DHCP server is not responding to an x86 client's request, you see the following messages:

Intel(R) Boot Agent PXE Base Code (PXE-2.1 build 0.86)

Copyright(C) 1997-2007, Intel Corporation

CLIENT MAC ADDR 00 14 4F 29 04 12 GUID FF2000008 FFFF FFFF FFFF 7BDA264F1400

DHCP......... No DHCP or ProxyDHCP offers were received

PXE-MOF: Exiting Intel Boot Agent

The timeout message indicates that the client is sending a DHCP request and not getting a response. This issue is probably due to an error in the DHCP configuration. Check to see if your client is configured correctly in the DHCP server.

Tasks such as installing and updating IPS packages, setting publishers, and modifying images require more privilege.

Version5.1.37-0.1/4 is installed(see note 1 below) and this version can be updated (see note 2 below).

Note:

* 1The “i” in the I column indicates that these packages are installed in this image.

2An “f” in the F column indicates the package is frozen. If a package is frozen, you can only install or update to packages that match the frozen version.

*The pkg list command tells you whether a package is installed in the current image and whether an update is available. With no options or operands, this command lists all packages that are installed in the current image. To narrow your results, provide one or more package names. You can use wildcards in the package names. Package variants for an architecture or zone type that does not match this image are not listed.

Note:

Not A:

* Jumpstart Profiles and Rules would have to be converted to be used in Automated Installer.

Use the js2ai utility with the -r option to convert both JumpStart rules and their associated profiles to AI criteria and manifests.

*Both Solaris Custom JumpStart and Oracle Solaris Automated Installer (AI) provide hands-free installation of multiple systems on a network. Clients are booted over the network, and once the client is booted, the installer takes over.
