Processing Restore Missions

Restoring in Control-D is performed by a restore mission.

The restore process consists of four stages:

Build the list of restore candidates
The list is an accumulation of all restore requests that were interactively selected in the History User Reports List screen. The requests are processed when the restore mission is activated (as set out below).
Merge the restore candidate list with the restore JCL skeleton
Submit the restore job
Analyze the results of the restore job

Two restore missions are predefined for you:

A cyclic restore mission, activated automatically once every 60 minutes
An "ad hoc" restore mission, activated manually by adding a prerequisite condition (trigger)

In this exercise, you will use the cyclic restore mission.

To activate the cyclic "60 minutes" restore mission, do the following:
1. From the COMMAND field type =A and press Enter. The Active Missions Environment screen is displayed.

1. Find the restore mission in the list of missions with the FIND command. Type F RST0060M in the COMMAND field and press Enter.
As mentioned earlier, this cyclic restore mission is activated automatically once every 60 minutes. When is the next time this restore mission will be activated?
The ? (why) option on this screen supplies this information with a list of reasons for a "Wait" status. Use this option as follows:
1. Position the cursor to the left of restore mission RST0060M.
2. Type ? and press Enter. The following screen is displayed:
------------------------- RST0060M IS WAITING FOR: -----------------------(A.?)

COMMAND ===>                                                    SCROLL===> CRSR

It is likely that the current interval will not end during the next few minutes. However, a restore is needed now. The following steps outlined one of the ways this can be done.
Press PF03/PF15.
Position the cursor to the left of the restore mission, type H and press Enter. The restore mission changes its status to REQUEST HELD WAIT PROCESS.
Press Enter periodically to display the current status. After a few seconds, the restore mission status changes again to HELD WAIT PROCESS. Modification of missions on the Active Missions Environment screen can be performed only after changing the mission's status to HELD.
Position the cursor to the left of the restore mission.
Type Z and press Enter. The Active Missions Environment Zoom screen is displayed.

This Zoom screen allows you to see the definition of a mission listed in the Active Missions Environment screen, and gives you the option of modifying some parameters. The parameter to change is the NEXT TIME parameter. This parameter indicates the next time this cyclic mission is to be activated.
Type F NEXT in the COMMAND field, and press Enter.
Position the cursor in the NEXT TIME field using the Tab key.
Look at the bottom right of the screen to see the present time.
Type the present time plus two minutes and press Enter.
From the COMMAND field, type SAVE and press Enter.
You automatically return to the Active Missions Environment screen. Press Enter to see the current status. The restore mission status changes to REQUESTED CHANGE HELD WAIT PROCESS. After a few seconds, the status changes again to HELD WAIT PROCESS.
Now that the restore mission is updated, free it, as follows:
1. Position the cursor to the left of the restore mission.
2. Type F and press Enter. Within a few seconds the restore mission is freed and activated.
Once the mission is activated, the four stages mentioned earlier are performed. Press Enter periodically to display the current status. The restore mission enters a RESTORE-IN-PROCESS status. The submitted restore job requests the tape that was used in the backup job. (A message appears on the operator console.)
You may want to verify that the computer operator has mounted the tape. When the restore mission has the status ENDED OK, you may proceed.
