Global performance data control authority
This control limits the ability of a LP to view CP activity data for other LPs. Logical partitions with control authority for global performance data can view CP utilization data and Input/Output Processor (IOP) busy data for all of the LPs in the configuration. Additionally, gathering of channel measurements requires selection of this parameter.
Note: see Enabling HiperDispatch for z/OS Logical Partitions for
considerations for Hiperdispatch and global performance data.
With the exception of an LP that is a member of a WLM Cluster, an LP without control authority for the performance data can view only the CP utilization data for that LP.
Use the Customize/Delete Activation Profiles task to open a reset or image profile to enable global performance data control for an LP. The Global performance data control selection is located on the Security page for the LP.
