z/OS Capacity provisioning allows you to set up rules

defi ning the circumstances under which additional capac- ity should be provisioned in order to fulfi ll a specifi c busi- ness need. The rules are based on criteria, such as: a specifi c application, the maximum additional capacity that should be activated, time and workload conditions. This support provides a fast response to capacity changes and ensures suffi cient processing power will be available with the least possible delay even if workloads fl uctuate.

An installed On/Off CoD record is a necessary prerequisite for automated control of temporary capacity through z/OS Capacity Provisioning.

See z/OS MVS Capacity Provisioning User’s Guide (SA33-8299) for more information.

On/Off CoD Test: On/Off CoD allows for a no-charge test. No IBM charges are assessed for the test, including IBM charges associated with temporary hardware capacity, IBM software, or IBM maintenance. This test can be used to validate the processes to download, stage, install, acti- vate, and deactivate On/Off CoD capacity non-disruptively. Each On/Off CoD-enabled server is entitled to only one no- charge test. This test may last up to a maximum duration of 24 hours commencing upon the activation of any capac- ity resources contained in the On/Off CoD record. Activa- tion levels of capacity may change during the 24 hour test period. The On/Off CoD test automatically terminates at the end of the 24 hours period. In addition to validating the On/Off CoD function within your environment, you may choose to use this test as a training session for your per- sonnel who are authorized to activate On/Off CoD.

SNMP API (Simple Network Management Protocol Appli- cation Programming Interface) enhancements have also been made for the new Capacity On Demand features.

More information can be found in the System z10 Capacity On Demand User’s Guide, SC28-6871.

Capacity on Demand – Permanent Capacity

Customer Initiated Upgrade (CIU) facility: When your business needs additional capacity quickly, Customer Initiated Upgrade (CIU) is designed to deliver it. CIU is designed to allow you to respond to sudden increased capacity requirements by requesting a System z10 EC PU and/or memory upgrade via the Web, using IBM Resource Link, and downloading and applying it to your System z10 EC server using your system’s Remote Support connec- tion. Further, with the Express option on CIU, an upgrade may be made available for installation as fast as within a few hours after order submission.

Permanent upgrades: Orders (MESs) of all PU types and memory for System z10 EC servers that can be delivered by Licensed Internal Code, Control Code (LIC-CC) are eligible for CIU delivery. CIU upgrades may be performed up to the maximum available processor and memory resources on the installed server, as confi gured. While capacity upgrades to the server itself are concurrent, your software may not be able to take advantage of the increased capacity without performing an Initial Program- ming Load (IPL).
