Enabling and disabling the Application Response Measurement (ARM) services

Use the MODIFY WLM,AM command to enable or disable Application Response Measurement (ARM) services. For more information on ARM services, see, IBM Systems Software Information Center:
http://publib.boulder.ibm.com/infocenter/eserver/v1r2/index.jsp?topic=/ewlminfo/eicaaauthzosusers.htm
.
The complete syntax for the MODIFY WLM,AM command is:
 
F WLM,AM={DISABLE|ENABLE} 
WLM
The name of the job.
AM
Indicates that the state of ARM services is to be changed.
DISABLE
Disables ARM services. Applications calling any of the ARM services will receive a return code indicating that this function is not operational from that point on; however, the applications continue to run.
If ARM is disabled:
  • A running guest platform management provider (GPMP) terminates.
  • Manually starting the guest platform management provider (using the MODIFY WLM,GPMP,START command) results in message IWM078I.
  • Activating a WLM policy that contains a valid configuration for the guest platform management provider does not result in the start of a GPMP instance.
  • The state of the guest platform management provider is displayed as “DISABLED”. If ARM is enabled again, the state of the guest platform management provider changes to “STOPPED”. To start the guest platform management provider again, you need to use the MODIFY WLM,GPMP,START command to manually start it.
See Starting, stopping and modifying options for the guest platform management provider for details about GPMP.
ENABLE
Enables previously disabled ARM services. ARM-instrumented applications that are already active at the time this command is invoked must be restarted if the ARM calls should be processed. In addition, when the ARM services are enabled, you can restart the GPMP.
