Oracle 1z0-580 - Oracle Solaris 11 Installation and Configuration Essentials

How to Loopback Mount a File That Is Usually Not Visible in a Labeled Zone

This procedure enables a user in a specified labeled zone to view files that are not exported from the global zone by default.

Halt the zone whose configuration you want to change.

# zoneadm -z zone-name halt

Loopback mount a file or directory.

For example, enable ordinary users to view a file in the /etc directory.

# zonecfg -z zone-name

add filesystem

set special=/etc/filename

set directory=/etc/filename

set type=lofs

add options [ro,nodevices,nosetuid]

end

exit

Note - Certain files are not used by the system, so that loopback mounting them has no effect. For example, the /etc/dfs/dfstab file in a labeled zone is not checked by Trusted Extensions software. For more information, see Sharing Files From a Labeled Zone.

Start the zone.

# zoneadm -z zone-name boot

Note:

*In this Solaris release, you create a ZFS file system share and publish the share as follows:

Create the file system share and define the NFS or SMB share properties by using the zfs share command.

*ZFS File Sharing Within a Non-Global Zone

In previous Solaris releases, you could not create and publish NFS or SMB shares in a Oracle Solaris non-global zone. In this Solaris release, you can create and publish NFS shares by using the zfs set share command and the legacy share command with a non-global zone.

*If a ZFS file system is mounted and available in a non-global zone, it can be shared in that zone.

*A file system can be shared in the global zone if it is not mounted in a non-global zone or is not shared to a non-global zone.

*If a ZFS file system's mountpoint property set to legacy, the file system can be shared by using the legacy share command.

Use the zpool split command to split a mirrored storage pool, which detaches a disk or disks in the original mirrored pool to create another identical pool.

B:Built-in Virtualization

Whatever the needs of your cloud infrastructure, Oracle has a comprehensive suite of built-in virtualization technologies to compliment your business requirements. 

Choose from Oracle Solaris Zones, OVM Server for SPARC, OVM Server for x86 and OVM VirtualBox. With Oracle Solaris Zones, administrators can rapidly provision secure and isolated virtual environments in which to deploy cloud applications and services.

D:

Oracle Solaris is the best platform for the cloud because it combines key computing elements - operating system, virtualization, networking, storage management, and user environment - into a stable, secure, mission-critical foundation that customers can depend on

An M represents a modified file or directory, an R is a renamed filesystem objects.

The Live Media provides administrators with an opportunity to explore the Oracle Solaris 11.1 environment without installing it on a system. The system boots off the media directly allowing administrators to start the installer should they choose to install it to a system.

Note:

*You have several alternatives for where to install Oracle Solaris 11:

Inside a virtual machine on top of your existing operating system

On the bare metal as a standalone operating system

On the bare metal alongside your existing operating system(s) (multiboot scenario)

*Booting a system using the none milestone can be very useful for debugging startup problems. There is no equivalent run level to the none milestone.

*If problems with starting services occur, sometimes a system will hang during the boot. This procedure shows how to troubleshoot this problem.

2.Boot without starting any services.

This command instructs the svc.startd daemon to temporarily disable all services and start sulogin on the console.

ok boot -m milestone=none

2.Log in to the system as root.

3.Enable all services.

# svcadm milestone all

4.Determine where the boot process is hanging.

When the boot process hangs, determine which services are not running by running svcs -a. Look for error messages in the log files in /var/svc/log.

After fixing the problems, verify that all services have started.

Verify that all needed services are online.

# svcs -x

Verify that the console-login service dependencies are satisfied.

This command verifies that the login process on the console will run.

# svcs -l system/console-login:default

6.Continue the normal booting process.

C:When you assign a network to a global zone, you must define the mode of the network, either Shared IP or Exclusive IP:

In Shared IP mode, the network interface is used by more than one zone. You define the network interface when you you assign the global zone to the network.

In Exclusive IP mode, the network interface is dedicated to the zone. An exclusive network must be declared for the global zone when you assign network to the global zone. Then you configure the IP configuration for the non-global zone.

Not B: There is no command dladm disableto disable a network interface.

Not D: There is no command netconfig disable to disable a network interface.

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.

Not D:

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

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.
