Scheduling classes provide different CPU access characteristics to threads that are based on algorithmic logic. The scheduling classes include:

Realtime scheduling class (RT) (not a)

Interactive scheduling class (IA)

Fixed priority scheduling class (FX) (not b)

Timesharing scheduling class (TS) (not c)

Fair share scheduling class (FSS) (not E)

How to Create a Virtual Network Interface

This procedure shows how to create a virtual network interface card (VNIC).

1. Create a VNIC over a datalink.

# dladm create-vnic -l link vnic

link is the name of the datalink over which the VNIC is configured.

vnic is the VNIC which you can label with a customized name as well.

2. Create a VNIC IP interface over the link.

# ipadm create-ip vnic

3. Configure the VNIC with a valid IP address.

If you are assigning a static IP address, use the following syntax:

# ipadm create-addr -T static -a address addrobj

where addrobj uses the naming format interface/user-defined-string, such as e1000g0/v4globalz.

How to Manually Specify Target Systems for Probe-Based Failure Detection

1. Add a route to a particular host to be used as a target in probe-based failure detection.

$ route -p add -host destination-IP gateway-IP -static

where destination-IP and gateway-IP are IPv4 addresses of the host to be used as a target. For example, you would type the following to specify the target system 192.168.10.137, which is on the same subnet as the interfaces in IPMP group itops0:

$ route -p add -host 192.168.10.137 192.168.10.137 -static

This new route will be automatically configured every time the system is restarted. If you want to define only a temporary route to a target system for probe-based failure detection, then do not use the -p option.

2.Add routes to additional hosts on the network to be used as target systems.

* zone.max-processes

Maximum number of process table slots

simultaneously available to this zone.

Because both normal processes and

zombie processes take up process table

slots, the max-processes control thus

protects against zombies exhausting the

process table. Because zombie processes

do not have any LWPs by definition, the

max-lwps control cannot protect against

this possibility

Note:

* prctl - operations on a process

Use the prctl command to make runtime interrogations of and modifications to the resource controls associated with an active process, task, or project on the system.

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.

* AI Server Software Requirements include:

Default router

Ensure that your AI server has a default route set by using the netstat command to show network status. If your AI server does not have a default route set, you can set a static default route by populating the /etc/defaultrouter file with the IP address of a static default route for your server's network.

* For any currently active NCP (fixed or reactive), use the route command with the -p option to persistently add a route:

# route -p add default ip-address

Because this command applies the specified route to the currently active NCP, the default route is removed and potentially replaced, if the active NCP changes.

Incorrect:

Not A, Not B: The svccfg command manipulates data in the service configuration repository. svccfg can be invoked interactively, with an individual subcommand, or by specifying a command file that contains a series of subcommands.

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

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.
