System requirements

iCap requires the following system resources:

  • The master PAS requires:
    • Version 2.4 or later of the IBM z/OS system
    • Version 3.1 of iCap
    • A separate PAS where only iCap is running. That is, the master PAS cannot run on a PAS that is shared with other BMC AMI Ops products.

Requirements

  • The agent PASs require:

    • Version 2.4 or later of the z/OS system
    • Version 3.1, 3.0, or 2.0 of iCap 
    • (if the agent PAS is running iCap 3.0) PTF BQY1841 applied to the PAS
    • (if the agent PAS is running iCap 2.0) PTFs BQY1320 and BQY1841 applied to the PAS

    Important

    • A policy requires only one master PAS.
    • The master PAS must be running same version of iCap as the agent PASs, or a later version. If the master PAS is running an earlier version than the agent PASs, functionality is restricted.

    • BMC recommends running an active agent on every LPAR that you want iCap to manage.

      iCap can function with only one active agent on every managed CPC, however, WLM importance data is not available for LPARs that are running without active agents. iCap manages LPARs that are running without active agents by priority, instead.

    • If you want to run iCap across multiple CPCs in a CMP environment, version 2.0 agent PASs are not supported. You can run version 2.0 agents when iCap is managing only a single CPC.

  • The IBM z/OS BCPii component must be running on the system where the master PAS runs.

    Important

    If you want to run in manage mode, before you begin to use iCap, the BCPii address space must be up and running on the LPAR where the master PAS is running.

By default, the master and agent PASs assign themselves to the SYSSTC WLM service class. BMC recommends that you also assign the CASs to which the PASs are connected to the SYSSTC service class.

Important

  • Do not allow the IBM Capacity Provisioning (CPM) component (or any other product) to manage and modify the defined capacity of an LPAR or the group capacity limit of a capacity group. Doing so would cause iCap to exceed the MSU limit.
  • iCap does not support IBM z/VM guests.
