Temporary fix

Comments

• With this APAR, z/VSE 6.2 provides support for the
  System Recovery Boost function on the IBM z15 server.
  
  - General purpose processors (CPs) running at subcapacity can
    be boosted to full capacity for a limited time. During IPL
    and standalone dump processing, these processors will
    be boosted for up to 60 minutes; during system shutdown,
    these processors will be boosted for up to 30 minutes.
  - The z/VSE system automatically enables the boost during IPL
    and during standalone dump processing.
  - To enable the boost for system shutdown, use the SYSDEF SYSTEM
    command.
  - The SYSDEF SYSTEM command has been extended by a new parameter
    to enable and to disable the boost: SYSDEF SYSTEM,BOOST=START
    to enable the boost during system shutdown and SYSDEF SYSTEM,
    BOOST=STOP to disable both the IPL and shutdown boost.
  - If a boost is not terminated using the SYSDEF SYSTEM,BOOST=
    STOP command, the z/VSE system will automatically stop the
    boost after the respective IPL or shutdown boost period has
    expired. The remaining minutes don't carry over to a
    following boost.
  - The SIR command output has been extended by a new indication
    'RECOVERY BOOST ACTIVE' that is displayed when a boost is
    active. It is also displayed in a z/VM guest environment when
    the z/VM system has a boost active.
  - The QUERY SYSTEM command output displays the current System
    Recovery Boost status of the system.
  - When using REIPL command subsequent IPL and/or shutdown boosts
    may fail. Use the HMC/SE Load Task as circumvention.
