Oracle 1z0-822 Oracle Solaris 11 Advanced System Administration Exam Practice Test

Only verbose mode is selected (-v) not checkpoints 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. Checkpointing is optional.

Note:

* 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 your selection of files, packages, and scripts for the image that is being built. This process uses the checkpointing options that are available in the distro_const command.

* distro_const Command Options

/ distro_const build manifest

Builds an image in one step using specified manifest file

/ distro_const build -v

Verbose mode

/ distro_const build -l manifest

Lists all valid checkpoints at which you can pause and resume building an image

/ distro_const build -p checkpoint_name manifest

Pauses building an image at a specified checkpoint

/ distro_const build -r checkpoint_name manifest

Resumes building an image from a specified checkpoint

/ distro_const build -h

Displays help for the command

* After you have set up the manifest file that you plan to use and, if desired, customized the finalizer scripts, you are ready to build an image by running the distro_const command.

You can use the distro_const command to build an image in either of the following:

In one step

Pausing and restarting the build as needed to examine the content of the image and debug the scripts during the build process

A: The pkd.depotd service is managed by SMF under the service identifier svc:/application/pkg/server.

D:

* Example:

Configure pkg.depotd to provide remote access. pkg.depotd provides an HTTP interface to a pkg repo. Here we are going to make the repo server listen on port 10000, and use the repo dir we created as its default.

# svcadm disable pkg/server

# svccfg -s pkg/server setprop pkg/inst_root = /data/myrepo

# svccfg -s pkg/server setprop pkg/port = 10000

# svcadm refresh pkg/server

# svcadm enable pkg/server

* pkg.depotd is the depot server for the image packaging system. It provides network access to the data contained within a package repository. Clients that do not support direct access to a repository through the file system, or for which network access is the only available or preferred method of transport, typically use the package depot.

A service can be configured to run within a limited set of privileges, rather than as the all-powerful root user.

Not on compression setting:

compression=on | off | lzjb | gzip | gzip-N

Controls the compression algorithm used for this dataset. The

"lzjb" compression algorithm is optimized for performance while

providing decent data compression. Setting compression to "on" uses

the "lzjb" compression algorithm.

Incorrect:

Not A, Not E: Should not use commas like this.

Not B, Not D: There is no property algorithm named to this command. To specify the use of the lzjb compression command we must use compression=lzjb.

Install services are created with a default AI manifest, but customized manifests or derived manifests scripts (hereafter called “scripts”) can be added to an install service by using the create-manifest subcommand.

* Example:

Add the new AI manifest to the appropriate AI install service, specifying criteria that define which clients should use these installation instructions.

# installadm create-manifest -n s11-x86 -f ./mem1.xml -m mem1 \

-c mem="2048-unbounded"

* Syntax

installadm create-manifest -n|--service svcname

-f|--file manifest_or_script_filename

[-m|--manifest manifest_name]

[-c|--criteria criteria=value|list|range... |

-C|--criteria-file criteriafile]

[-d|--default]

How to Move a Running Process Into a New Task

This example shows how to associate a running process with a different task and new project.

To perform this action, you must either be superuser, or be the owner of the process and be a

member of the new project.

1. Become superuser or assume an equivalent role

2. Obtain the process ID of thebook_catalogprocess.

# pgrep book_catalog

8100

3. Associate process8100with a new task ID in thebooksiteproject.

# newtask -v -p booksite -c 8100

17

The -coption specifies that newtaskoperate on the existing named process.

4. Confirm the task to process ID mapping.

# pgrep -T 17

8100

Incorrect:

Not C: projmod does not change the processes of a project.

The projmod utility modifies a project's definition on the system. projmod changes the definition of the specified project and makes the appropriate project-related system file and file system changes.

* pkgrepo provides the ability to create and manage pkg package repositories. Package repositories are a predefined set of directories and files that permit the storage and retrieval of package data by pkg and publication clients such as pkgsend or pkgrecv.

* Use the pkgrecv command to copy the repository.

Example:

# pkgrecv -s http://pkg.oracle.com/solaris/release/ -d /export/repoSolaris11 '*'

create uses a default template of SYSdefault. The default template can be changed on a system-wide basis using the default_template SMF property of the svc:/system/zones:default service.

Note:

create [-F] [ -a path |-b | -t template]

Create an in-memory configuration for the specified zone. Use create to begin to configure a new zone

By default, a new BE is automatically created when you perform one of the following operations:

* (D) Set the be-policy image policy to always-new. Under this policy, all package operations are performed in a new BE set as active on the next boot.

* Update particular key system packages such as some drivers and other kernel components. This can happen when you install, uninstall, update, change variant, or change facet.

* Often a new BE is created when you execute the pkg update command to update all packages that have updates available.

* Specify any of the following options: --be-name, --require-new-be, --backup-be-name, --require-backup-be.

When an underlying interface of an IPMP group fails, a typical solution would be to replace the failed interface by attaching a new NIC. RCM records the configuration information associated with any NIC that is detached from a running system. If you replace a failed NIC with an identical NIC, then RCM automatically configures the interface according to the persistent configurations that had been previously defined by using the ipadm command.

Incorrect:

Not A, not D: You can replace a failed NIC with a different NIC, provided that both are the same type, such as Ethernet. In this case, RCM plumbs the new interface after it is attached. If you did not use customized link names when you first configured your interfaces, then you will have to configure the new NIC before you can add the interface to the IPMP group.

Not C: devfsadm, devfsadmd- administration command for /dev and /devices

Note:

* 1. On the system with the IPMP group configuration, assume the Primary Administrator role or become superuser.

2. Display the test address configuration

3. Remove the physical interface.

4. Replace the physical interface.

From the poolcfg –c info command output we see that FSS (Fair Share Scheduler) is used.

From the prctl command output we see that zone z1 has been configured with a zone.cpu-shares value of 40.

* The pool_default has a value of 100 CPU shares.

* prstat

- report active process statistics

Option –Z

-Z

Report information about processes and zones. In this mode, prstat displays separate reports about processes and zones at the same time.

Use one of the following methods to restart the depot server process:

B: Use svcadm(1M) to restart the application/pkg/server instance.

C: Send a SIGUSR1 signal to the depot server process using kill(1). This executes a “graceful restart” that leaves the process intact but reloads all configuration, package, and search data:

# kill -USR1 pid

Note:

* The pkd.depotd service is managed by SMF under the service identifier svc:/application/pkg/server.

* /etc/default/mpathd

Contains default values used by the in.mpathd daemon.

* By default, in.mpathd limits failure and repair detection to IP interfaces that are configured as

part of a named IPMP group. Setting TRACK_INTERFACES_ONLY_WITH_GROUPS to no enables failure and repair detection on all IP interfaces, even if they are not part of a named IPMP group. IP interfaces that are tracked but not part of a named IPMP group are considered to be part of the “anonymous” IPMP group. In addition to having no name, this IPMP group is

special in that its IP interfaces are not equivalent and thus cannot take over for one another in

the event of an IP interface failure. That is, the anonymous IPMP group can only be used for

failure and repair detection, and provides no high-availability or load-spreading

All interfaces in the same group must have the same STREAMS modules configured in the same order.

The beadm utility enables you to create a new boot environment based on an existing snapshot.

Note:

* You can manage the boot environments on your system either by using the beadm command or by using the Package Manager.

* A boot environment is a bootable instance of the Oracle Solaris operating system image plus any other application software packages installed into that image. System administrators can maintain multiple boot environments on their systems, and each boot environment can have different software versions installed.

A: To restart remote logging:

svccfg -s system-log setprop config/log_from_remote=true

svcadm restart system-log

D: You can run 'snoop' on the interface to see if you see syslog packets leaving the server

Note:

* vmstat reports virtual memory statistics regarding kernel thread, virtual memory, disk, trap, and CPU activity.

Incorrect:

Not B: sr, pages scanned by clock algorithm

Not C: free

A: Configure pkg.depotd to provide remote access. pkg.depotd provides an HTTP interface to a pkg repo. Here we are going to make the repo server listen on port 10000, and use the repo dir we created as its default.

# svcadm disable pkg/server

# svccfg -s pkg/server setprop pkg/inst_root = /data/myrepo

# svccfg -s pkg/server setprop pkg/port = 10000

# svcadm refresh pkg/server

# svcadm enable pkg/server

B: Set-Publisher

With -G (--remove-origin), remove the URI or path from the list of origins for the given publisher. The special value * can be used to remove all origins.

Incorrect:

Not D: unset-publisher publisher ...

Remove the configuration associated with the given publisher or publisher

Not E: set-publisher

Update an existing publisher or add a package publisher. If no options affecting search order are specified, new publishers are appended to the search order and are thus searched last.
