Capacity Provisioning

Capacity Provisioning is designed to simplify the management of temporary capacity, Defined Capacity, and Group Capacity. The scope of z/OS® Capacity Provisioning is to address capacity requirements for relatively short term workload fluctuations for which On/Off Capacity on Demand or Soft-Capping adjustments are applicable. It is not a replacement for the Capacity Management process. 1

Capacity Provisioning can help you manage processor capacity on IBM® z Systems when a suitable On/Off Capacity on Demand record is available. Capacity provisioning allows you to change the activation level of that On/Off CoD record with respect to general purpose capacity, the number of IBM zEnterprise Application Assist Processors (zAAPs), and the number of IBM z Integrated Information Processors (zIIPs). Capacity Provisioning can help you monitor and manage the Defined Capacity and Group Capacity through policy based automation or through commands from the z/OS Console.

The Capacity Provisioning task, introduced with z/OSMF V1R13, provides a browser-based user interface for working with the Capacity Provisioning Manager on a z/OS system. With the Capacity Provisioning task, you can perform the following functions:

  • Manage connections to a Provisioning Manager and use them to transfer provisioning policies and domain configurations to the Provisioning Manager, or to query various status reports.
  • View the status of a Provisioning Manager by displaying reports about the domain status, the active configuration, and the active policy.
  • Manage, create, modify, and delete provisioning policies and domain configurations from a central shared repository. 2
  • Import and export domain configurations and policies. 2
  • Install and activate policies and domain configurations for the domain the Provisioning Manager controls. 2
