plan can be a ‘single-level resource plan’ or it can be a ‘multi-level
resource plan’. In a single-level resource plan, the resources are
allocated among the associated resource groups. For example, the
policy_rec plan allocates CPU resources among the three consumer
groups viz., claims, sales, and legal. The resource group claims gets
55% of CPU time, sales gets 25%, and legal receives 20% of CPU time.
multi-level resource plan, sub-plans represent a hierarchy of plans
and their associated resource groups. The policy_rec provides for two
sub-plans, sales and claims, and one resource group named ‘legal’. The
claims sub-plan allocates 60% of CPU time to the resource group called
‘LIFE’ and 40% to the group called ‘AUTO’. The sales sub-plan
allocates 70% of CPU time to the resource group called ‘NEWSALES’ and
30% to the group called ‘MARKET’.
