Default versus small environment

Privileged support runs under one of two environments:

Default environment: By default, this mode is activated when all preconditions are satisfied. Use this mode for large installations that might require several privileged jobs to run when a resource shortage occurs. Activation rules require more free resource than is required for small environment. Privileged resource reservation is also larger.
Small environment: Use this environment for small installations with limited resource that is defined. Also, when a shortage occurs, only a few privileged jobs are allowed to diagnose and correct the situation. At the most, 10 privileged jobs can be started at once within the MAS when using the small environment.

This mode requires you to take action. The Default environment must be turned off with the $TLIMITS command. For example:

Figure 1. Sample Default environment turned off using $TLIMITS

-           $tlimits,priv=off
            $HASP1402 Privilege Resource Support ended
            $HASP1490 LIMITS(1)
  LIMITS(1) 
  PRIVILEGE SUPPORT IS OFF
  .
  .
  .

Then, turn on small environment with the $TLIMITS command. For Example:

Figure 2. Sample Small environment turned on using $TLIMITS

-           $tlimits,priv=on,smallenv=on
            $HASP1401 Privilege Resource Support activated for -- BERTs.
            $HASP1401 Privilege Resource Support activated for -- JOEs.
            $HASP1401 Privilege Resource Support activated for -- SPOOL/Tracks.
            $HASP1401 Privilege Resource Support activated for -- JQEs.
            $HASP1490 LIMITS(1)
  LIMITS(1) 
  PRIVILEGE SUPPORT IS ON,SMALL ENVIRONMENT IS ON
  .
  .
  .

The $DLIMITS command can be used to determine which environment is active. Both environments share all of the privileged capabilities as described.
