Example. Displaying Administratively Customized Properties (here only admin layer is displayed with –l)

The following command uses SMF layers to display administratively customized properties.

example% svcprop -p config -l admin svc:/network/dns/client

(A) config/domain astring admin my.domain.com

(D) config/nameserver net_address admin 10.22.33.44 10.44.33.11

Note:

* config/nameserver refers to the Solaris DNS server.

/ The nameserver keyword specifies DNS servers to query using IP address.

Example:

The /etc/resolv.conf file contains configuration directives for the DNS resolver. The following resolv.conf example shows two name servers and three search suffixes:

domain nj.bigcorporation.com

nameserver 192.168.10.11

nameserver 192.168.20.88

* The svcprop utility prints values of properties in the service configuration repository. Properties are selected by -p options and the operands

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

next_state none

logfile /var/svc/log/system-zones:default.log

restarter svc:/system/svc/restarter:default

manifest /etc/svc/profile/generic.xml

manifest /lib/svc/manifest/system/zones.xml

manifest /lib/svc/manifest/system/zonestat.xml

dependency require_all/none svc:/milestone/multi-user-server (online)

dependency optional_all/none svc:/system/pools/dynamic:default (disabled)

dependency optional_all/none svc:/system/zones-monitoring (online)

C: You cannot activate an unbootable BE in a nested BE.

BE solaris-1 is marked with !R.

Unbootable BEs inside of a nested BE are represented by an exclamation point (!)

BF: BE solaris-1 is marked with !R.

Unbootable BEs inside of a nested BE are represented by an exclamation point (!)

Incorrect:

Not A: BE1 can be activated. It is bootable (not marked with a !)

Not D: Different BEs can be used in the two zones.

Not E: BE solaris-1 is not marked with an N. The Active field indicates whether the boot environment is active now, represented by N

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

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.

* How to Reconfigure a Zone to Use a VNIC

1. Become an administrator.

2. Create the VNIC.

(C) 3. Change the zone's IP type from shared to exclusive.

4.Change the zone's interface to use a VNIC.

5. Verify and commit the changes you have implemented and then exit the zone.

(D) 6. Reboot the zone.

7. Log in to the zone.

8. Configure the VNIC with a valid IP address.

* Example. Reconfiguring a Zone Configuration to Use a VNIC

In this example, zone2 already exists as a shared zone. The zone also uses the primary interface of the system rather than a virtual link. You need to modify zone2 to use vnic2. To use vnic2, zone2's IP type must first be changed to exclusive. Note that some of the output is truncated to focus on the relevant information that relates to virtual networks.

global# dladm create-vnic -l net0 vnic2

global# zonecfg -z zone2

(C) zonecfg:zone1> set ip-type=exclusive

zonecfg:zone1> remove net physical=net0

zonecfg:zone1> add net

zonecfg:zone1:net> set physical=vnic2

zonecfg:zone1:net> end

zonecfg:zone1> verify

zonecfg:zone1> commit

zonecfg:zone1> exit

(D) global# zoneadm -z zone2 reboot

global# zlogin zone2

zone2# ipadm create-ip vnic2

zone2# ipadm create-addr -a 192.168.3.85/24 vnic2

ipadm: vnic2/v4

zone2# exit

global# vi /etc/hosts

#

1 localhost

127.0.0.1 localhost

192.168.3.70 loghost #For net0

192.168.3.80 zone1 #using vnic1

192.168.3.85 zone2 #using vnic2

Note:

* The default AI manifest must work for any client that does not match a custom manifest, for any service based on this image.

See 1 below.

Precedence Rules

For nfsmapid to work properly, NFS version 4 clients and servers must have the same domain. To ensure matching NFS version 4 domains, nfsmapid follows these strict precedence rules:

1. The daemon first checks the SMF repository for a value that has been assigned to the nfsmapid_domain parameter. If a value is found, the assigned value takes precedence over any other settings. The assigned value is appended to the outbound attribute strings and is compared against inbound attribute strings.

2. If no value has been assigned to nfsmapid_domain, then the daemon checks for a domain name from a DNS TXT RR. nfsmapid relies on directives in the /etc/resolv.conf file that are used by the set of routines in the resolver. The resolver searches through the configured DNS servers for the _nfsv4idmapdomain TXT RR.

3. If no DNS TXT record is configured to provide a domain name, then the nfsmapid daemon uses the value specified by the domain or search directive in the /etc/resolv.conf file, with the directive specified last taking precedence.

4. If the /etc/resolv.conf file does not exist, nfsmapid obtains the NFS version 4 domain name by following the behavior of the domainname command. Specifically, if the /etc/defaultdomain file exists, nfsmapid uses the contents of that file for the NFS version 4 domain. If the /etc/defaultdomain file does not exist, nfsmapid uses the domain name that is provided by the network's configured naming service.
