The Zoom screen is very similar to the Job Scheduling Definition screen. Instead of displaying the permanently defined job scheduling definition, however, the Zoom screen displays the job scheduling definition of the requested job order.
In the Zoom screen, you can change or delete TIME FROM and TIME UNTIL criteria for a job order. You can now display the Zoom screen, which is requested from the Active Environment screen.
The Active Environment screen is displayed. Note the Z (Zoom) option at the bottom of the Active Environment screen. This option displays the Zoom screen.
You will recall from Chapter 2, "Scheduling Definition and Manual Intervention," that before you could delete a job from the Active Environment screen, you had to place the job in Held status. To make changes through the Zoom screen, you must first hold the job in the Active Environment screen, and then enter the Zoom screen.

There are differences between the permanent definition displayed in the Job Scheduling Definition screen, and the job order definition displayed in the Zoom screen. For example, the definition in the Zoom screen does not display Basic scheduling parameters—these parameters are irrelevant once the job order is in the Active Environment. And the Zoom screen displays parameters such as SEARCH COUNTER, which are not found in the job scheduling definition, but which are relevant to the job order processing and have values set by Control-M.
The runtime scheduling parameters you defined for IDJOB3 appear in the Zoom screen.

Of the runtime scheduling criteria you defined, the TIME FROM and TIME UNTIL range remains the only problem. You can resolve this by simply changing the TIME values in the Zoom screen.
At this point, it is important that you note the following:
These exercises are designed to show you the workings of scheduling parameters and to show you how you can intervene if absolutely necessary. But runtime criteria are defined for a reason, and unless you are certain of what you are doing, intervention can do much more harm than good. For example, intervening to cause the submission of a job before its predecessor job has run can potentially do great damage.
Therefore, intervention in job processing should be left only to those who are specifically authorized and who have the knowledge necessary to intervene appropriately.
You can now exit the Zoom screen and see the result.
