The relationship between jobs, job groups and layouts is an important
concept to understand when using the MOTIF Editor/Monitor. Each of
these entities will be explained in relation to each other and the
overall program in the following chapters.
1.3.1 Jobs
Jobs are the fundamental building block of job groups and layouts. A job group should have at least one job in it and may have many. When the job is first displayed its icon should be represented as a sitting man, with the job name adjacent to it. When there are several jobs in a job group they may easily be moved about to represent the flow of interdependencies.
A jobs position, interdependencies, and characteristics may change
within a session but these changes will not be saved unless the layout
is saved. Specifics of job changes will be detailed in the following
chapters.
1.3.2 Job Groups
Job groups are comprised of a collection of jobs that may or may not be linked by interdependencies. A job group is usually composed of jobs that are related in some way. For instance you may want all of your batch jobs in one job group while print jobs are contained in another. Since the jobs in groups usually contain interdependencies, the flow of the jobs is logically easier to view as the jobs execute in real time.
1.3.3 Layouts
A layout is a collection of one or more job groups and or monitor
windows. Layouts can be saved, edited and loaded. All positioning and
sizing of windows is retained when the layout is saved. You may want to
create a layout for different kinds of scheduling you need to do. For
instance, you may have a set of job groups that are associated with a
certain project, day of the week or department. You can collect these
job groups and monitor windows into a layout and load it when necessary.
1.4 Mouse interaction
This describes the use of a mouse within job group windows and in
conjunction with the Command Center. It is assumed that the user is on
a workstation that features a three button mouse
as shown in Figure 1-12. Though the mouse you are using has three
buttons (MB1, MB2 and MB3), we will only be using two. The left button
(MB1) will be referred to as MB#1 and clicking and the right button
(MB3) will be referred to as MB#3 or right clicking. However, these
buttons may be configured in the opposite way. The middle button is not
used in the MOTIF Editor/Monitor.
For instance, the statement "click on the first job in the job group" means put the cursor over the job and click with MB1.

1.5 Job ids in the MOTIF Editor/Monitor
An understanding of the concept of job set ids is essential to using
the MOTIF Editor/Monitor effectively. This describes the use of the set
id number and how it relates to the MOTIF Editor/Monitor.
All job groups have a job set id in the MOTIF Editor/Monitor. Each job in the job group share the same id number. The job set id can be set automatically by SCHEDULE or explicitly defined using the Monitor set id... selection on the Control menu in the job group window.
The job set id is easily viewable in the title bar of the job group window. This makes it possible to see what job set id is currently running. Figure 1-13 shows two typical title bars. The top bar is extracted from a job set with a fixed set id. and the bottom bar is extracted from a job set using the highest active set id.
