Pass the Oracle Oracle Solaris 11 System Administrator 1z0-820 Questions and answers with CertsForce

The dispadmin command displays or changes process scheduler parameters while the system is running.

-c class

Specifies the class whose parameters are to be displayed or changed. Valid class values are: RT for the real-time class, TS for the time-sharing class, IA for the inter-active class, FSS for the fair-share class, and FX for the fixed-priority class. The time-sharing and inter-active classes share the same scheduler, so changes to the scheduling parameters of one will change those of the other.

-g

Gets the parameters for the specified class and writes them to the standard output.

installadm add-manifest

Associates manifests with a specific install

service, thus making the manifests available on

the network, independently from creating a

service. When publishing a non-default manifest,

it is required to associate criteria either via

criteria entered on the command line (-c) or

via a criteria XML file (-C).

How to Create an iSCSI LUN

The following steps are completed on the system that is providing the storage device.

1.Create a ZFS storage pool.

Example: target# zpool create sanpool mirror c2t3d0 c2t4d0

(C)2. Create a ZFS volume to be used as a SCSI LUN.

(D)3. Create a LUN for the ZFS volume.

Example:

target# stmfadm create-lu /dev/zvol/rdsk/sanpool/vol1

Logical unit created: 600144F0B5418B0000004DDAC7C10001

4. Confirm that the LUN has been created.

Example

target# stmfadm list-lu

LU Name: 600144F0B5418B0000004DDAC7C10001

(F) 5. Add the LUN view.

This command makes the LUN accessible to all systems.

target# stmfadm add-view 600144F0B5418B0000004DDAC7C10001

How to Create the iSCSI Target

This procedure assumes that you are logged in to the local system will contains the iSCSI target.

Note: The stmfadm command manages SCSI LUNs. Rather than setting a special iSCSI property on the ZFS volume, create the volume and use stmfadm to create the LUN.

(H) 1. Enable the iSCSI target service.

target# svcadm enable -r svc:/network/iscsi/target:default

(I) 2. Create the iSCSI target.

target# itadm create-target

B:

Note: You can create custom AI manifests for particular clients.

Create a custom XML AI manifest file. This method is best suited to an environment where few systems require custom provisioning. Most systems to be installed have identical or similar hardware and will be provisioned identically.

Write a script that dynamically creates an AI manifest for each client at installation time. Use this method to create a custom installation for each client, based on client characteristics discovered at installation time.

E: AI Server Software Requirements include

Software package repository

Ensure that the install server can access an IPS software package repository. AI requires the install/installadm package.

F: Install Server Requirements

Any system that meets these requirements can be used as an AI install server, including laptops, desktops, virtual machines, and enterprise servers. The install server can be either an x86 machine or a SPARC machine. An x86 install server can install both SPARC and x86 clients, and a SPARC install server can install both SPARC and x86 clients.

Note: To install clients over the network, AI requires a separate system to be an install server. On the install server, create an AI install service to provide a net image and instructions for installing the Oracle Solaris 11 OS on different clients.

You can use the pkg set-publisher command to change a publisher URI.

Changing a Publisher Origin URI

To change the origin URI for a publisher, add the new URI and remove the old URI. Use the -g option to add a new origin URI. Use the -G option to remove the old origin URI.

# pkg set-publisher -g http://pkg.example.com/support \

-G http://pkg.example.com/release example.com

Note: You can use either the install or update subcommand to update a package.

The install subcommand installs the package if the package is not already installed in the image. If you want to be sure to update only packages that are already installed, and not install any new packages, then use the update subcommand.

B: The /etc/default/syslogd file contains the following default parameter settings. See FILES.

LOG_FROM_REMOTE

Specifies whether remote messages are logged. LOG_FROM_REMOTE=NO is equivalent to the -t command-line option. The default value for LOG_FROM_REMOTE is YES.

mount: mount-point /DS9 does not exist.

To solve the mount point error condition, check that the mount point exists on the client. Check the spelling of the mount point on the command line or in the /etc/vfstab file (B) on the client, or comment outthe entry and reboot the system.

Note: The /etc/vfstab file lists all the file systems to be automatically mounted at system boot time, with the exception of the /etc/mnttab and /var/run file systems.

E: showmount

This command displays all clients that have remotely mounted file systems that are shared from an NFS server, or only the file systems that are mounted by clients, or the shared file systems with the client access information. The command syntax is:

showmount [ -ade ] [ hostname ]

where -a prints a list of all the remote mounts (each entry includes the client name and the directory), -d prints a list of the directories that are remotely mounted by clients, -e prints a list of the files shared (or exported), and hostname selects the NFS server to gather the information from. If hostname is not specified the local host is queried.

F: * mountd Daemon

This daemon handles file-system mount requests from remote systems and provides access control. The mountd daemon checks /etc/dfs/sharetab to determine which file systems are available for remote mounting and which systems are allowed to do the remote mounting.

* Commands for Troubleshooting NFS Problems

These commands can be useful when troubleshooting NFS problems.

rpcinfo Command

This command generates information about the RPC service that is running on a system.

dlstat show-aggr [-r | -t] [-i interval] [-p] [ -o field[,...]] [-u R|K|M|G|T|P] [link]

Display per-port statistics for an aggregation.
