5.3 The Job Object
A job is deployed to the Orchestrate Server to automate processes, such as coordinating VM
provisioning, high-performance computing, or general data center management. Jobs consist of Job
Development Language (JDL) scripts(s) and might have one or more policies associated with them.
Policies define job arguments and other facts that are used by the job.
Usually a Job has logic that runs on the PlateSpin Orchestrate Server itself and schedules work to
run on one or more managed resources that are running the PlateSpin Orchestrate Agent. The logic
that is dispatched and run on the managed resources is called a joblet. A job may or may not define
one or more joblets.
A JDL script is partitioned into a "Job" section and one or more "Joblet" sections. The joblet
sections of the script describe most of the work of a job. The PlateSpin Orchestrate Server
dispatches joblets to resources in the grid where the work is done.
The Job object also contains Facts with attributes that are used for job and joblet control. Policies
associated with the job also control the job. The Orchestrate Development Client has an
administrative ("admin") view in the Explorer Panel that lets you edit these objects.
This section includes information about a Job object that is visible in the Explorer view and the
accompanying Admin view of the Orchestrate Development Client:

Section 5.3.2, "The Job Info/Groups Tab," on page 68
Section 5.3.3, "The JDL Editor Tab," on page 78
Section 5.3.4, "The Job Library Editor Tab," on page 79
Section 5.3.5, "The Job Policies Tab," on page 80
Section 5.3.6, "The Job Constraints/Facts Tab," on page 81
5.3.1 Job Groups
Any group object displayed in the Explorer panel represents a collection of similar object types.
Groups can also be created automatically, as in the case when a provisioning adapter (PA) discovers
a local repository on a VM host. For example, the
automatically creates a local repository for that VM host and places the created repository in a
repository group. You can also create groups manually in the Development Client, either by
xen30
clicking the Actions menu and choosing Create Job Group or by right clicking a Job Group object
(anywhere in the Job hierarchy) and selecting New Job Group.
5.3.2 The Job Info/Groups Tab
The page that opens under the Info/Configuration tab of the Job admin view includes several
collapsible sections on the page where you can configure the general information and attributes of
the job.
