Starting the iCap master and agent PASs

This section explains how to start and stop the iCap master and agent product address spaces (PASs).

The iCap master PAS collects data from all of the CPCs in your environment and manages the LPARs and capacity groups that are running on the CPCs (and defined in the policy). In most cases, each CPC has only one master PAS. For more information, see Policy-guidelines.

An agent PAS is a simplified version of the master PAS. Agent PASs collect data and return it to the master PAS. Multiple agent PASs can run on a CPC. For more information about how the PASs run in the iCap environment, see iCap-architecture.

Important

  • Ensure that your environment is set up with the required system resources. For more information, see System-requirements.
  • Ensure that at least one active agent is running on each CPC that you want to manage before the master PAS is started.
  • If you start the PAS before the CAS, the PAS waits indefinitely for the CAS to start, and does not terminate.
  • If the CAS terminates, the master PAS that is connected to the CAS also terminates.
  • After the CAS terminates, the master PAS cannot continue to manage DCs and GCLs until the CAS restarts. By terminating the PAS when the CAS terminates, iCap ensures that DCs and GCLs are correctly restored.
  • BMC recommends that you automate starting and stopping the PASs. You can also specify a PAS START command in the CAS JCL, which automatically restarts the PAS each time the CAS restarts. For more information, see the automated operations documentation for your product.
