twsClusterAdm command with examples of usage

About this task

The twsClusterAdm command configures your IBM Workload Scheduler agent type installations in the Microsoft® Windows cluster environment.

You can configure the following IBM Workload Scheduler agent type installations:
  • Fault-tolerant agent only.
  • Both fault-tolerant agent and dynamic agent.
  • Dynamic agent only.

Both fault-tolerant agents and dynamic agents are monitored and can be involved in failover. For details, see the ftaOff and lwaOn monitoring options of twsClusterAdm parameter opts, (described in Syntax).

If you want to install a domain manager on a cluster environment, you must specify the link option using the twsClusterAdm parameter opts (described in Syntax). See Example 9: First installation of domain manager in Windows cluster environment, specifying generic options for a worked example.

The twsClusterAdm command:

  • Configures IBM Workload Scheduler on all the nodes of the cluster or on a new joining cluster node.
  • Installs the new IBM Workload Scheduler Cluster resource type for a first time installation. The name of this new cluster resource type is ITWSWorkstation.
  • Creates an instance of the IBM Workload Scheduler Cluster resource type within a cluster group.
  • Removes IBM Workload Scheduler configuration from one or more nodes of the cluster.
  • Upgrades the IBM Workload Scheduler Cluster resource type if a new version is available.
It works in several steps to complete a cluster-aware installation:
  • Determines if setup is running in a cluster environment.
  • Copies the IBM Workload Scheduler resource DLL to the cluster nodes.
  • Updates IBM Workload Scheduler services startup mode from automatic to manual.
  • Installs IBM Workload Scheduler services and registry key on the other nodes (because the current services and registry key was installed by the normal product installation).
  • Registers IBM Workload Scheduler Resource Types.
  • Creates a new instance of the IBM Workload Scheduler resource within a given cluster group (virtual server) and updates localopts and JobManager.ini configuration files.
