Using the trace facility with WPARs

Edit online

You can use the trace facility to isolate system problems by monitoring selected system events in a WPAR.

The following tracing capabilities are available for WPARs:
  • Launching a trace from within a WPAR
  • Correlating a trace entry to a WPAR
  • Filtering which WPAR trace entries to log from the global environment
  • Filtering which WPAR entries to report from the global environment
  • Running more than one kernel trace at the same time
  • Additional trace utility hooks
Note: A maximum of seven WPARs can run the trace facility at the same time.

By default you cannot run trace facility in a WPAR. To enable the trace facility from a WPAR, you must grant PV_KER_RAS privilege to the WPAR. You can grant this privilege when you run the mkwpar command or by running the chwpar command with the -S privs+=PV_KER_RAS flag.
