VM66829: Z/VM 7.4 CP: FEATURE PACK - FEATURE 01 FIX 00

Obtain the fix for this APAR.

APAR status

• Closed as new function.

Error description

• This is the APAR for z/VM 7.4 Feature Pack 1.  As such it
  contains the following new functions:
  
  Two-Speed Monitoring
  -------------------------
  Two-Speed Monitoring provides a mechanism for collecting z/VM
  Monitor data at two different sampling rates. The underlying
  requirement is to be able to allow some guests to collect
  detailed data for a relatively brief period so it can be
  preserved if a situation arises that requires it for analysis,
  while allowing other guests to collect data less frequently and
  over longer time periods for customary purposes such as
  real-time monitoring or feeding the z/VM Performance Data Pump.
  This avoids disrupting existing client processes that rely on
  Monitor data collection.
  
  TRSOURCE Subchannel Set Support
  ----------------------------------------
  TRSOURCE currently supports 4-digit device addresses for IO
  tracing. This item extends the support to 5-digit device
  addresses, which comprise a subchannel-set (SS) number
  concatenated to the left of the device address. This applies
  only to real device addresses and therefore to the operand of
  the TRSOURCE command RDEV keyword.

  Two-Speed Monitoring
  --------------------
  
  Two-Speed Monitoring provides a mechanism for collecting z/VM

  real-time monitoring or feeding the z/VM Performance Data Pump.
  This avoids disrupting existing client processes that rely on
  Monitor data collection.
  
  A new SUBINTERVAL operand of the MONITOR SAMPLE command can be
  specified to define the subinterval duration. QUERY MONITOR
  reports the SUBINTERVAL value. MONWRITE accepts a new option
  to enable it to collect subinterval data. See the CP Commands
  and Utilities Reference for more information about these
  commands and their responses. Several messages - HCP6225,
  HCP6232E, HCP6255I and HCP6264I have been added or changed.
  They are described in CP Messages and Codes.
  
  
  TRSOURCE IO 5-digit Device Support
  ----------------------------------
  
  TRSOURCE currently supports 4-digit device addresses for IO
  tracing. This item extends the support to 5-digit device
  addresses, which comprise a subchannel-set (SS) number
  concatenated to the left of the device address. This applies
  only to real device addresses and therefore to the operand of
  the TRSOURCE command RDEV keyword. Refer to the CP Commands and
  Utilities Reference for more information about the changes to
  the TRSOURCE and QUERY TRSOURCE commands.
