Service Dependency. This element identifies a group of FMRIs upon which the service is in some sense dependent.

ATTRIBUTE: Grouping:

Possible values:

'require_all',

'require_any',

'exclude_all',

‘optional_all'

Note:

* Example 1:

name='network'

grouping='require_all'

restart_on='none'

type='service'>

* In this example, let's choose the svc:/system/zones:default service instance. We can use the -l option and the service name to get more information, as shown in Listing 3.

# svcs -l svc:/system/zones:default

fmri svc:/system/zones:default

name Zones autoboot and graceful shutdown

enabled true

state online

The Zone Management profile grants the power to manage all of the non-global zones on the system to a user.

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

Note:

* (not A, not B, not D) The privs key contains a comma-separated list of privilege numbers that will be effective when the command or action is run.

* euid and uid contain a single user name or a numeric user ID. Commands designated with euid run with the effective UID indicated, which is similar to setting the setuid bit on an executable file. Commands designated with uid run with both the real and effective UIDs. Setting uid may be more appropriate than setting the euid on privileged shell scripts.

* egid and gid contain a single group name or a numeric group ID. Commands designated with egid run with the effective GID indicated, which is similar to setting the setgid bit on a file. Commands designated with gid run with both the real and effective GIDs. Setting gid may be more appropriate than setting guid on privileged shell scripts.

* /etc/security/exec_attr is a local database that specifies the execution attributes associated with profiles.

/etc/security/exec_attr

Locally added entries. Make sure that the shipped header remains intact.

/etc/security/exec_attr.d/*

Entries added by package installation.

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.

A: IPS package manifests can be signed, with the signatures becoming part of the manifest.

Signatures are represented as actions just as all other manifest content is represented as actions.

C: A manifest can have multiple independent signatures.

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.

Example 1: Creating a New Shell

The following example creates a new shell in the canada pro-

ject, displaying the task id:

example$ id -p

uid=565(gh) gid=10(staff) projid=10(default)

example$ newtask -v -p canada

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.
