Pass the Oracle Oracle Solaris 1z0-822 Questions and answers with CertsForce

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.

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.

Create the etherstub.

global# dladm create-etherstub etherstub

Create a VNIC over the etherstub.

global# dladm create-vnic -l etherstub vnic

Note: Etherstubs / Virtual Switches

The Etherstub is craeated as a dummy device to connect the various virtual NICs. User can imagine etherstub as a Virtual Switch to help visualize the virtual network as a replacement for a physical network where each physical switch is replaced by a virtual switch.

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.

The zfs get command supports the -H and -o options, which are designed for scripting. You can use the -H option to omit header information and to replace white space with the Tab character. Uniform white space allows for easily parseable data. You can use the -o option to customize the output in the following ways:

* The literal name can be used with a comma-separated list of properties as defined in the Introducing ZFS Properties section.

* A comma-separated list of literal fields, name, value, property, and source, to be output followed by a space and an argument, which is a comma-separated list of properties.

The following example shows how to retrieve a single value by using the -H and -o options of zfs get:

# zfs get -H -o value compression tank/home

on

The capped-memory resource sets limits for physical, swap, and locked memory. Each limit is optional, but at least one must be set.

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.

prctl

- get or set the resource controls of running processes, tasks, and projects.

The prctl utility allows the examination and modification of the resource controls associated with an active process, task, or project on the system. It allows access to the basic and privileged limits and the current usage on the specified entity.

Incorrect:

not A: ipcs provides information on the ipc facilities for which the calling process has read access.

not D:

rctladm

- display or modify global state of system resource controls

Not E: prstat - report active process statistics

Note:

* In the Oracle Solaris operating system, the concept of a per-process resource limit has been extended to the task and project entities.

zpool detach pool device

Detaches device from a mirror. The operation is refused if there

are no other valid replicas of the data.

dumpadm - configure operating system crash dump

SYNOPSIS

/usr/sbin/dumpadm [-nuy] [-c content-type] [-d dump-device]

[-m mink | minm | min%] [-s savecore-dir]

[-r root-dir] [-z on | off]

The options include:

A: -d dump-device

Modify the dump configuration to use the specified dump device.

B: -s savecore-dir

Modify the dump configuration to use the specified directory to

save files written by savecore.

D: -m mink | minm | min%

Create a minfree file in the current savecore directory indicating

that savecore should maintain at least the specified amount of free

space in the file system where the savecore directory is located.

E: -z on | off

Modify the dump configuration to control the operation of savecore on reboot. The options are on, to enable saving core files in a compressed format, and off, to automatically uncompress the crash dump file. The default is on, because crash dump files can be very large and require less file system space if saved in a compressed format.
