Problem summary

• ****************************************************************
  * USERS AFFECTED:  All users of IBM WebSphere Application      *
  *                  Server Liberty for z/OS                     *
  ****************************************************************
  * PROBLEM DESCRIPTION: ABEND0C4 in checkAuthorization() during *
  *                      ntv_registerServer call                 *
  ****************************************************************
  * RECOMMENDATION:                                              *
  ****************************************************************
  The ntv_registerServer function is driven during server startup.
  Part of this function is to call the checkAuthorization() method
  which is running in 64-bit
  addressability.  This routine needs to make calls to 31-bit SAF
  services.  The setup for the call saved the dynamic area address
  into what it thought was an unused register prior to invoking
  the 31-bit routine.  On return from the call to the 31-bit
  routine the high-part of the register used to save the 64-bit
  address of the callers dynamic area was zeros.  When it
  referenced its dynamic area it resulted in an ABENDS0C4.
  

Problem conclusion

• Code has been modified in the native security code to not rely
  on the contents of the general purpose registers across the mode
  switch and call to the 31-bit
  SAF service.
  
  The fix for this APAR is currently targeted for inclusion in fix
  pack 22.0.0.5.  Please refer to the Recommended Updates page for
