VM66679: *VMEVENT ENHANCEMENTS

Obtain the fix for this APAR.

APAR status

• Closed as new function.

Error description

• In response to customer requirements, the *VMEVENT Enhancements
  line item will deliver new and enhanced event records.
  New event records are generated to provide data associated with
  virtual machine console disconnection and reconnection. Logon
  event records are extended to identify the logon-by user (if
  any) and to identify the terminal connection. The
  logoff-timeout-started and logoff-timeout-service event records
  are enhanced to report large timeout intervals correctly, by
  appending a 32-bit unsigned interval value to the existing
  message format. Redundant runnable (Class 0 Type 5) events are
  eliminated. The runnable event is now reported only when the
  virtual machine is leaving a non-runnable state.

  *VMEVENT Enhancements will deliver new and enhanced event
  records. New events are added for machine console reconnection
  (Class 0, Type 28) and disconnection (Class 0, Type 29). The
  runnable event (Class 0, Type 5) is modified to only report on a
  state change. The logoff-timeout-started (Class 0, Type 3) and
  logoff-timeout-service (Class 1, Type 3) event records are
  enhanced to report large timeout intervals correctly, by
  appending a 32-bit unsigned interval value to the existing
  message format. The logon event (Class 0, Type 0) is modified to
  include logon-by and terminal information in the message.
