Privilege resource activation rules

Privilege support determines whether support for a resource is activated or not. The decision is always based on the number of free elements at the time when the resource is to be activated. This decision differs for default versus small environment. The amount of resource that is reserved also differs for both environments. All resources have a maximum (MAX) number that can be reserved for privileged users. See Privilege resource activation rules, Table 1, for information about activation rules for each resource.

Table 1. Default environment resource activation and reservation rules
Resource	Free required to activate	Number reserved for privilege	MAX
BERTs	20,000	1% of free	756
JOEs	20,000	1% of free	600
JQEs	10,000	1% of free	300
SPOOL(TGs)	20,000 TGs	400 TGs	400

Note: TG is track group.

Table 2. Small environment resource activation and reservation rules
Resource	Free required to activate	Number reserved for privilege	MAX
BERTs	1,200	150	150
JOEs	600	60	60
JQEs	100	10	10
SPOOL(TGs)	380**	45 TGs per MAS member	32*45

** Also required for activating SPOOL small environment: If the product of (45 TGs times number of MAS members) exceeds 12.5 % of total free TGs -- then activation cannot occur and $HASP1403 message is issued.

When a resource is activated, the following message is issued:

$HASP1401 - Privilege Resource Support activated for <resource type>

If a resource cannot be activated, then the following message is issued:

$HASP1403 - Privilege Resource Support could not be activated for <resource type>

$D LIMITS command can be used to display resource limits, usage, and shortage status. This includes an indication if privileged support is activated for the resource, default or small environment active, whether there is a resource shortage, the amount of privileged resource that is reserved left for privileged use. The example below shows output for JQEs by using the $D LIMITS(JQE) command.

The following display illustrates DEFAULT environment JQE privileged status:

Note: The display indicates privileged support is ON, and 109 JQEs are reserved for privileged jobs. Currently, there is no JQE shortage.
