GLYPH<SM590000> Confirmation mode 

In this mode, CPM processes capacity provisioning policies and interrogates the installed temporary offering records. Every action that is proposed by the CPM must be confirmed by the operator. 

GLYPH<SM590000> Autonomic mode 

This mode is similar to the confirmation mode, but no operator confirmation is required. 

Several reports are available in all modes that contain information about the workload, provisioning status, and the rationale for provisioning guidelines. User interfaces are provided through the z/OS console and the CPMC application. 

The provisioning policy defines the circumstances under which more capacity can be provisioned (when, which, and how). The criteria features the following elements: 

GLYPH<SM590000> A time condition is when provisioning is allowed: 

– Start time indicates when provisioning can begin. 

– Deadline indicates that provisioning of more capacity is no longer allowed. 

– End time indicates that deactivation of capacity must begin. 

GLYPH<SM590000> A workload condition is which work qualifies for provisioning. It can have the following parameters: 

– The z/OS systems that can run eligible work. 

– The importance filter indicates eligible service class periods, which are identified by WLM importance. 

– Performance Index (PI) criteria: 

GLYPH<129> Activation threshold: PI of service class periods must exceed the activation threshold for a specified duration before the work is considered to be suffering. 

GLYPH<129> Deactivation threshold: PI of service class periods must fall below the deactivation threshold for a specified duration before the work is considered to no longer be suffering. 

– Included service classes are e ligible service class periods. 

– Excluded service classes are service cl ass periods that must not be considered. 

Tip: If no workload condition is specified, the full capacity that is described in the policy is activated and deactivated at the start and end times that are specified in the policy. 

GLYPH<SM590000> Provisioning scope is how much more capacity can be activated and is expressed in MSUs. 

The number of zIIPs must be one specification per CPC that is part of the CPD and are specified in MSUs. 

The maximum provisioning scope is the maximum extra capacity that can be activated for all the rules in the CPD. 

In the specified time interval, the provisioning rule is that up to the defined extra capacity can be activated if the specified workload is behind its objective. 

The rules and conditions are named and stored in the Capacity Provisioning Policy.
