Pass the Oracle Solaris 1z0-821 Questions and answers with ExamsMirror

If the boot environment is unbootable, it is marked with an exclamation point (!) in the Active column in the beadm list output.

The beadm command restricts actions on unbootable boot environments as follows:

You cannot activate an unbootable boot environment. (B)

You cannot destroy a boot environment that is both unbootable and marked as active on reboot.

You cannot create a snapshot of an unbootable boot environment.

You cannot use an unbootable boot environment or boot environment snapshot with the -e option of beadm create.

You cannot rename an unbootable boot environment. (C)

A: You can use the distribution constructor to create the following types of Oracle Solaris images:

* (A) x86 or SPARC ISO Image for Automated Installations

* Oracle Solaris x86 live CD image

* x86 or SPARC Oracle Solaris text installer image

* x86 Oracle Solaris Virtual Machine

Note: You can use the distribution constructor to build custom Oracle Solaris images. Then, you can use the images to install the Oracle Solaris software on individual systems or multiple systems. You can, also, use the distribution constructor to create Virtual Machine (VM) images that run the Oracle Solaris operating system.

D: Checkpointing Options

You can use the options provided in the distro_const command to stop and restart the build process at various stages in the image-generation process, in order to check and debug the image that is being built. This process of stopping and restarting during the build process is called checkpointing.

Installing a ZFS Root Pool

The installer searches for a disk based on a recommended size of approximately 13 GB.

A: If the network is setup to perform automated installations, you can perform a text installation over the network by setting up an install service on the network and selecting a text installation when the client system boots.

B: After a fresh install of Solaris 11 express, only the console mode is activated.

To add Gnome, simply do :

$ sudo pkg install slim_install

This will install additional packages that are not installed by default.

D: The text installer advantages over the GUI installer include:

* In addition to modifying partitions, the text installer enables you to create and modify VTOC slices within the Solaris partition.

F: How do I upgrade my Solaris 10 or lower systems to Solaris 11?

Unfortunately, you CAN'T. There is no direct upgrade installer or other tool that will allow you to upgrade from earlier releases of Solaris to Solaris 11. This is primarily due to the vast changes in the packaging mechanism in Solaris 10.

www.oracle.com would have to be resolved to an IP name by the domain name service.

Kill -9

Kill (terminates without cleanup)

Only works if issued by process owner or super user (root)

The program cannot respond to this signal; it must terminate

Note: Unix provides security mechanisms to prevent unauthorized users from killing other processes. Essentially, for a process to send a signal to another, the owner of the signaling process must be the same as the owner of the receiving process or be the superuser.

From the output exhibit we can deduce that the shell has id 15156.

It has spawned three subprocesses:

grep: id 15166

ps –aef 15165

The remaining 15163 must be the subshell (see note below).

This is the id of the process which should be terminated.

C: The Group ID (GID) field contains the group's numerical ID. GIDs can be assigned whole numbers between 100 and 60000.

D: Group names contain only lowercase characters and numbers.

C: To change the default behavior of the Fast Reboot feature on the SPARC platform, so that a fast reboot is automatically performed when the system reboots, see below.

The following example shows how to set the property's value to true on the SPARC platform, so that a fast reboot is initiated by default:

# svccfg -s "system/boot-config:default" setprop config/fastreboot_default=true

# svcadm refresh svc:/system/boot-config:default

D: Fast Reboot implements an in-kernel boot loader that loads the kernel into memory and then switches to that kernel.

The firmware and boot loader processes are bypassed, which enables the system to reboot within seconds.

The Fast Reboot feature is managed by SMF and implemented through a boot configuration service, svc:/system/boot-config. The boot-config service provides a means for setting or changing the default boot configuration parameters. When the config/fastreboot_default property is set to true, the system performs a fast reboot automatically, without the need to use the reboot -f command. This property's value is set to true on the x86 platform. For task-related information, including how to change the default behavior of Fast Reboot on the SPARC platform, see Accelerating the Reboot Process on an x86 Based System.

Note: One new feature, called Fast Reboot, will allow the system to boot up without doing the routine set of hardware checks, a move that can make system boot times up to two-and-a-half times faster, Oracle claimed. This feature can be handy in that an administrator applying a patch or software update across thousands of Solaris deployments can reboot them all the more quickly.

The svcs command displays information about service instances as recorded in the service configuration repository.

-d Lists the services or service instances upon which the given service instances depend.
