  ****************************************************************
  IBM Z System Recovery Boost is a new feature that is available
  with the IBM z15 (z15). It can temporarily leverage additional
  processor capacity during IPL and shutdown times to reduce the
  overall downtime due to recovery or maintenance activities.
  This new function requires z/OS V2.3 and OA57849 or z/OS V2.4.
  At IPL time, a system can automatically participate in the boost
  unless the BOOST system parameter in IEASYSxx is set to NONE.
  At shutdown time, the operator has to explicitly activate the
  boost by starting the new started procedure IEASDBS that is
  provided by z/OS.
  
  With OA58302, support is added to SA z/OS to automatically
  activate System Recovery Boost upon shutdown of a system.
  SA z/OS checks whether the operational prerequisites are met
  and if so starts the started procedure IEASDBS. Specifically,
  SA z/OS checks whether it runs on z/OS V2.3 or higher, whether
  boost is enabled in IEASYSxx and that the system is not already
  operating in boost mode. IEASDBS is started only when all
  conditions are met.
  SA z/OS does not check whether it runs on a z15.
  
  If System Recovery Boost should not be activated automatically
  upon system shutdown, even if enabled by the operating system,
  the administrator can pass the new INGREQ parameter BOOST=NO
  with the INGREQ ALL request. To permanently disable System
  Recovery Boost during shutdown of a system, the administrator
  can set the global variable INGREQ_BOOST to NO.
  
  When a system is shut down via GDPS, SA z/OS also automatically
  activates System Recovery Boost when the operational
  prerequisites are met. To avoid automatic activation of System
  Recovery Boost, the administrator can set the advanced
  automation option AOF_AAO_SHUTDOWN_BOOST to NO.
  
  IEASDBS activates System Recovery Boost only once. If it has
  been started manually before an operator requests a shutdown via
  SA z/OS, SA z/OS will detect it and not start the procedure
  again. If the procedure is started manually after an operator
  requests shutdown via z/OS and z/OS has already started it
  automatically, messages on the system console indicate that an
  error occurred but no further action is required.
  

Problem conclusion

Temporary fix

Comments

• Changes have been made to implement the automatic activation of
  System Recovery Boost at system shutdown.
