1z0-580 Practice Exam Questions with Answers Oracle Solaris 11 Installation and Configuration Essentials Certification

Creating a ZFS Storage Pool with Cache Devices

You can create a storage pool with cache devices to cache storage pool data. For example:

# zpool create tank mirror c2t0d0 c2t1d0 c2t3d0 cache c2t5d0 c2t8d0

Note:

*Creating a Basic Storage Pool

The following command creates a new pool named tank that consists of the disks c1t0d0 and c1t1d0:

#zpool status tank

pool: tank

state: ONLINE

scrub: none requested

config:

NAME STATE READ WRITE CKSUM

tank ONLINE 0 0 0

mirror-0 ONLINE 0 0 0

c2t0d0 ONLINE 0 0 0

c2t1d0 ONLINE 0 0 0

c2t3d0 ONLINE 0 0 0

cache

c2t5d0 ONLINE 0 0 0

c2t8d0 ONLINE 0 0 0

errors: No known data errors

# zpool create tank c1t0d0 c1t1d0

These whole disks are found in the /dev/dsk directory and are labelled appropriately by ZFS to contain a single, large slice. Data is dynamically striped across both disks.

*Creating a Mirrored Storage Pool

To create a mirrored pool, use the mirror keyword, followed by any number of storage devices that will comprise the mirror. Multiple mirrors can be specified by repeating the mirror keyword on the command line. The following command creates a pool with two, two-way mirrors:

# zpool create tank mirror c1d0 c2d0 mirror c3d0 c4d0

*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.

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.

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.

The routeadm command is used to administer system-wide configuration for IP forwarding and routing. IP forwarding is the passing of IP packets from one network to another; IP routing is the use of a routing protocol to determine routes.

-e option...

Enable the specified option. The effect is to prepare the associated services (svc:/network/ipv4-forwarding:default in the case of ipv4-forwarding) for enabling. By means of the routing-svcs variable, the routing daemons are specified to be enabled on subsequent boot or when routeadm -u is run.

-d option...

Disable the specified option. The effect is to prepare the associated services (svc:/network/ipv4-forwarding:default in the case of ipv4-forwarding) for enabling. By means of the routing-svcs variable, the routing daemons are specified to be disabled on subsequent boot or when routeadm -u is run.

Through the zonecfg utility, the file-mac-profile can be set to one of the following values (see note below). All of the profiles except none will cause the /var/pkg directory and its contents to be read-only from inside the zone.

*none

Standard, read-write, non-global zone, with no additional protection beyond the existing zones boundaries. Setting the value to none is equivalent to not setting file-mac-profile property.

* strict

*fixed-configuration

Permits updates to /var/* directories, with the exception of directories that contain system configuration components.

IPS packages, including new packages, cannot be installed.

Persistently enabled SMF services are fixed.

SMF manifests cannot be added from the default locations.

Logging and auditing configuration files can be local. syslog and audit configuration are fixed.

* flexible-configuration

Note:

zonecfg file-mac-profile Property

By default, the zonecfg file-mac-profile property is not set in a non-global zone. A zone is configured to have a writable root dataset.

In a solaris read-only zone, the file-mac-profile property is used to configure a read-only zone root. A read—only root restricts access to the runtime environment from inside the zone.
