Creating a new scheduling environment

If you have not yet defined any scheduling environments, Figure 1 shows the first panel you will see.

Command ===> _______________________________________________________


No scheduling environments exist.  Would you like to create a
scheduling environment or list resources for scheduling
environments?

Select one of the following options.
__  1.  Create Scheduling Environment
    2.  Create Resource(s)

From here you can either enter 1 to create a scheduling environment, or a 2 to create resources. (You might want to create all of your resources, for instance, before creating your first scheduling environment. This is covered in Creating a new resource directly from the main panel.)

Note: Until you have created at least one scheduling environment (no matter how many resources you create), you will always see this initial panel.

Figure 2 shows the main Scheduling Environment Selection List panel. Assuming that you have at least one scheduling environment already created, this is the first panel you see when you work with scheduling environments.

By entering 1 on any Action line, you will go to the Create a Scheduling Environment panel, as shown in Figure 3. (You can also get there by putting the cursor under the Scheduling-Environment field at the top of the screen, and then entering 1 in the pop-up box.)

Selection For Scheduling Environment DB2LATE

Action Codes: A=Add  S=Select  X=XREF  /=Menu Bar

Action  Resource Name     In Use  Resource Description
  __    CICS001           YES     CICS Subsystem
  S_    DB2A                      DB2 Subsystem
  __    IMS1              YES     IMS Subsystem
  S_    PRIMETIME         YES     Peak Business Hours

This panel shows all of the resource definitions in the service definition. The YES in the In Use field simply means that the resource name is currently a part of some scheduling environment. (It does not mean that it is in use by the scheduling environment you are defining when you get to this screen, in this case DB2LATE.)

You can select as many resources as you like. In this case, we'll select DB2A and PRIMETIME. Both have already been defined (although only PRIMETIME is currently being used by another scheduling environment). To make the resource name part of the scheduling environment, enter S on the Action line next to it. (Alternately, you can enter / next to the resource names and then put the cursor under the Resources field at the top of the screen and press Enter. Then select 2 from the options in the pop-up box.)

If you have many resources, you can use the LOCATE primary command to scroll the display to a particular resource name.

Note: You can create new resources from this panel, as well. See Creating a new resource while working with a scheduling environment.

This will take you back to the Create a Scheduling Environment panel, as shown in Figure 5.

Scheduling Environment Name    DB2LATE_________  Required
Description  . . . . . . . . . Offshift DB2 Processing_________

Action Codes: A=Add  D=Delete

                          Required

  __    DB2A              ON_______   DB2 Subsystem
  __    PRIMETIME         OFF______   Peak Business Hours

The DB2A and PRIMETIME names and descriptions are automatically brought back to this panel. Now you must specify either ON or OFF under the Required State field. In this example, we have chosen ON for DB2A and OFF for PRIMETIME (meaning that the DB2A resource state must be set to ON and the PRIMETIME resource state must be set to OFF for this scheduling environment to be satisfied).
