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

TheJumpStart Migration Utility (js2ai)is used to convert Oracle Solaris 10 JumpStart rules and profiles to a format that is compatible with AI manifest entries.

Note:

*There are no upgrade methods or tools available to transition from Oracle Solaris 10 to Oracle Solaris 11. You cannot use an installer to upgrade from Oracle Solaris 10 to Oracle Solaris 11. You must perform a fresh installation of Oracle Solaris 11.

A snapshot is a read-only point-in-time copy of a file system. The copy-on-write design

of ZFS makes them essentially “free” - They are space efficient and instantaneous, providing an invaluable part of backup strategies and synchronizing data between systems.

Incorrect:

Incorrect:

NotA:A ZFS vdev (aka "virtual device") is either:

a single disk, or

two or more disks that are mirrored, or

a group of disks that are organized using RAID-Z.

There are also special kinds of vdevs like hot-spares, ZIL or cache devices, etc.

Not D:

Clones are writeable snapshots, ideal for storing many private

copies of shared data for operations such as data migration, test

and development, or backup.

Storage

ZFS is the root file system on Oracle Solaris 11 offering a superior experience in terms of

manageability, scalability and data integrity. ZFS presents a pooled storage model that

completely eliminates the concept of volumes and the associated problems of partitions,

provisioning, wasted bandwidth and stranded storage. Thousands of file systems can draw

from a common storage pool, each one consuming only as much space as it actually needs. All

operations are copy-on-write transactions ensuring that the on-disk state is always valid.

Incorrect:

Not A:Network Auto-Magic(NWAM)is a project to simplify and automate network configuration on Solaris. Network Auto-Magic generally refers to Network Profiles, which allow users to specify various network configurations to be created depending on the current network conditions. The Service Discovery project, which incorporates Multicast DNS into Solaris, also fell under the Network Auto-Magic umbrella.

Not B:Pre-Flight Checker tool which can be used to check whether apps will work without modification on Solaris 11

Not C:Network Auto-Magic is a project to simplify and automate network configuration on Solaris. Network Auto-Magic generally refers to Network Profiles, which allow users to specify various network configurations to be created depending on the current network conditions. The Service Discovery project, which incorporates Multicast DNS into Solaris, also fell under the Network Auto-Magic umbrella.

Updating all of the packages on your installed system – To update all of the packages on your system that have available updates, use the pkg update command, as follows:

# pkg update

Running this command updates packages that you might not otherwise consider updating, for example, kernel components and other low-level system packages.

A:

*Oracle Solaris 11 adds transparent data encryption functionality to ZFS. All data and file system metadata (such as ownership, access control lists, quota information, and so on) are encrypted when stored persistently in the ZFS pool.

*A very simple example of using ZFS encryption is as follows:

#zfs create -o encryption=on rpool/export/project

Enter passphrase for 'rpool/export/project':

Enter again:

#zfs create rpool/export/project/A

#zfs create rpool/export/project/A/design

#zfs create rpool/export/project/B

D:compression=onreduces storate footprint

E:If you want to allow the filesystem to be managed inside the zone, use the zfs zoned=on option when creating or modifying the filesystem.

'stamf' doesn't match any instances

Note:

*Enabling the COMSTAR service

COMSTAR runs as a SMF-managed service and enabling is no different than usual. First of all, check if the service is running:

# svcs \*stmf\*

STATE STIME FMRI

disabled 11:12:50 svc:/system/stmf:default

If the service is disable, enable it:

# svcadm enable svc:/system/stmf:default

After that, check that the service is up and running:

# svcs \*stmf\*

STATE STIME FMRI

online 11:12:50 svc:/system/stmf:default

# stmfadm list-state

Operational Status: online

Config Status : initialized

ALUA Status : disabled

ALUA Node : 0

*Use the configuration element in the AI manifest for the client system to specify non-global zones.

Use the name attribute of the configuration element to specify the name of the zone.

Use the source attribute to specify the location of the config file for the zone.

The source location can be any http:// or file:// location that the client can access during installation.

*The following sample AI manifest specifies two Non-Global Zones: zone1 and zone2

You should replace the server_ip with the ip address of the NFS server.

name="http://pkg.oracle.com/solaris/release"/ >

pkg:/entire@latest

pkg:/group/system/solaris-large-server

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.
