Working With the Control-O/COSMOS Demo Environment

You can use the Control-O/COSMOS demo environment to familiarize yourself with Control-O/COSMOS functions (screens, commands, and so on). Use the following steps to guide you through Control-O/COSMOS.

1. Start Control-O (if it is not already active).
2. Start Control-O/COSMOS using command xxxINI (if this command was not already issued by a rule at Control-O/COSMOS startup).
3. Enter the Control-O/COSMOS Object Status screen using option OBJECT in the Control-O/COSMOS Main menu (screen OC). You can use this screen to view the current status of Control-O/COSMOS-controlled objects.
4. Exit the Object Status screen, and issue operator command xxxUP. This command sets the mode of demo Object databases to FREE and specifies UP as the desired status for each object.
5. Return to the Object Status screen to observe how Control-O/COSMOS-controlled objects are handled as a result of command xxxUP.

   Control-O/COSMOS-controlled objects are brought up in the order dictated by prerequisites defined in the demo Prerequisite database (for example, xxxJES2 is brought up before xxxVTAM, followed by applications that require VTAM to be up).

6. When all Control-O/COSMOS-controlled objects have a status of STEADY UP, issue command xxxDOWN.

   Objects are brought down in the reverse order from which they were brought up. This is due to inverse application of Control-O/COSMOS prerequisites.

7. Use the SYSIMAGE facility, described on page 100, to build an Object database that reflects your production environment.

   Objects defined using the SYSIMAGE facility are assigned a mode of FORCE_OK. This ensures that objects in your production environment are not modified by Control-O/COSMOS while operating in a demo environment.

   For more information about the SYSIMAGE facility, see SYSIMAGE Facility – Automatic Generation of an Object Database, and the CTOCTI utility in the INCONTROL for z/OS Utilities Guide.

8. Experiment with options in the Object Status screen and the Database Status screen. For more information about these screens, see Online Facilities.
9. Review the rules supplied with Control-O/COSMOS, and familiarize yourself with their logic.
