Example:

The default service model is contract, but may be modified. For this example, we are going to start the service with svc.startd. As a transient service, it will be started once and not restarted by adding the following lines to the manifest:

/>

Note:

svc.startd provides three models of service, which are

* Transient services—These are often configuration services, which require no long-running processes to provide service. Common transient services take care of boot-time cleanup or load configuration properties into the kernel. Transient services are also sometimes used to overcome difficulties in conforming to the method requirements for contract or wait services. This is not recommended and should be considered a stopgap measure.

* Contract services—These are the standard system daemons. They require processes which run forever once started to provide service. Death of all processes in a contract service is considered a service error, which will cause the service to restart.

* Wait services—These services run for the lifetime of the child process, and are restarted when that process exits.

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.

C: a user must be assigned to a default project, the processes that the user launches can be associated with any of the projects of which that user is a member.

D: How to Create a New Task

1.Log in as a member of the destination project, booksite in this example.

2.Create a new task in the booksite project by using the newtask command with the -v (verbose) option to obtain the system task ID.

machine% newtask -v -p booksite

16

The execution of newtask creates a new task in the specified project, and places the user's default shell in this task.

3.View the current project membership of the invoking process.

machine% id -p

uid=100(mark) gid=1(other) projid=4113(booksite)

The process is now a member of the new project.

Note:

* Projects are collections of tasks, which are collections of processes.

* Projects and tasks are used to label workloads and separate them from one another.

Incorrect:

Not A: The task collects a group of processes into a manageable entity that represents a workload component.

Not E: If no default project is found, the user's login, or request to start a process, is denied.
