Configuring the Scheduler › Define the Load Balancing Method

Define the Load Balancing Method

You can define the method that determines the percentage of CPU cycles available on a real machine belonging to a virtual machine. This method is used to achieve load balancing. The valid values are cpu_mon, vmstat, or job_load.

Notes:

• The default value is cpu_mon. For legacy agents, the default value is vmstat.

  Note: vmstat is displayed as the default value in the Machine Method field on the Scheduler - CA Workload Automation AE Administrator window of CA Workload Automation AE Administrator. The cpu_mon and vmstat default values are interchangeable. Based on the machine to which the load balancing request is sent, CA Workload Automation AE uses cpu_mon or vmstat method. If the load balancing request is sent to an agent, the cpu_mon method is invoked. If the load balancing request is sent to a legacy agent, the vmstat method is invoked.

• On UNIX, rstatd is also supported. The cpu_mon, vmstat, or rstatd settings check the CPU usage statistics of candidate machines, whereas the job_load setting checks only the job load and no real time usage of machine is required. The scheduler uses the job_load and max_load attributes to calculate the available load for a computer.
• The cpu_mon machine method does not apply to z/OS machines (CA Workload Automation Agent on z/OS) because the OMCPU job is not supported on z/OS.
• On UNIX, the equivalent configuration parameter is MachineMethod.

Follow these steps:

1. Click Start, Programs, CA, Workload Automation AE, Administrator.

   The Instance - CA Workload Automation AE Administrator window opens.

2. Select an instance from the Instance drop-down list in the Settings pane.
3. Click the Services icon on the toolbar.

   The Services - CA Workload Automation AE Administrator window appears, displaying a list of services installed on the selected instance.

4. Right-click the scheduler and select Stop.

   The scheduler stops.

5. Click the Scheduler icon on the toolbar.

   The Scheduler - CA Workload Automation AE Administrator window appears. The Controls tab is selected by default.

6. Enter the load balancing method in the Machine Method field, and click Apply.
7. Click the Services icon on the toolbar.

   The Services - CA Workload Automation AE Administrator window appears, displaying a list of services installed on the selected instance.

8. Right-click the scheduler and select Start.

   The scheduler starts. The load balancing method is defined.
