Step 3. Installing the agents

About this task

The master domain manager of the distributed end is the IBM Z Workload Scheduler controller, referred to as OPCMASTER. You must specify OPCMASTER in the Master CPU field of every new agent you install.

For details about installing the agents, see IBM Workload Scheduler: Planning and Installation. If you have not installed IBM Workload Scheduler agents before, here are a few introductory notes about installing IBM Workload Scheduler:
  • During installation, there is no difference between installing a fault-tolerant agent or a standard agent. You install a generic IBM Workload Scheduler agent. The difference is made in the CPUTYPE keyword of the CPUREC statement, where you specify if the agent will be standard or fault-tolerant (or extended). The difference between the two is that a fault-tolerant agent is autonomous in carrying on its workload after it receives the daily plan from its domain manager. A standard agent needs to be managed by its domain manager to run jobs. If the domain manager goes down, a standard agent cannot run jobs. Standard agents require less power and are normally considered for simpler workloads.
  • Among the information you are asked to provide while installing all agents, remember:
    • The value of the Master CPU field must be OPCMASTER.
    • The workstation name in the This CPU field is reduced to four characters (the first must be a letter) for end-to-end agents, while it normally extends to 16 characters in IBM Workload Scheduler. If you want to keep the same name in the IBM Z Workload Scheduler definition, you should follow this rule at installation time.
  • Domain managers are not determined by the installation program. Their role is specified when you configure the workstations in IBM Z Workload Scheduler.
  • If you want to include extended agents in the end-to-end with fault tolerance capabilities network, remember that they are logical entities hosted physically by fault-tolerant or standard agents. For each extended agent that you want to install:
    • Install one of the access methods available from IBM Workload Scheduler for Applications on one of your fault-tolerant or standard agents.
    • Follow the four-character naming convention as you did for the hosting agent. The name must be different from its host, because it will be defined as a different agent in IBM Z Workload Scheduler.
