VM66201: ALLOW VM DATA SPACE USE IN Z/ARCHITECTURE

Obtain the fix for this APAR.

APAR status

• Closed as new function.

Error description

• z/XC Architecture Support allows a z/Architecture virtual
  machine to exploit VM Data Spaces.
  It is an extension of the existing product that introduces
  a new virtual machine architecture mode, dubbed "z/XC".
  The value of this line item from the customer's viewpoint is
  that z/Architecture CMS can use existing facilities that
  exploit data spaces such as SFS DIRCONTROL directories.

  ****************************************************************
  This APAR provides support for VM Data Spaces in an XC virtual
  machine that has switched into z/Architecture mode.  Along with
  CMS APAR VM66425, this allows z/Architecture CMS (z/CMS) to use
  VM Data Spaces for functions such as accessing Shared File
  System (SFS) Directory Control (DIRCONTROL) directories.
  Performance Toolkit provides support for z/XC virtual machines
  in APAR VM66489.

Comments

• z/XC Architecture support will add a new virtual machine
  architecture mode that enables CMS applications running in
  z/Architecture to take advantage of multiple address spaces.  A
  z/XC guest will be able to exploit VM Data Spaces with
  z/Architecture in the same way that an ESA/XC guest can exploit
  them with Enterprise Systems Architecture.  This support will
  allow z/Architecture CMS (z/CMS) to use VM Data Spaces for
  functions such as accessing Shared File System (SFS) Directory
  Control (DIRCONTROL) directories.  It will also allow use of
  programs employing z/Architecture instructions and registers
  (within the limits of z/CMS support) and exploiting data spaces
  in the same CMS session.  For details of z/XC architecture see
  z/VM: z/Architecture Extended Configuration (z/XC) Principles
  of Operation (SC27-4940-00).
  
  VM66425 must be applied to CMS in order to use VM Data Spaces
  with ZCMS in an XC mode virtual machine.
  
  VM66489 must be applied to Performance Toolkit in order to
  get support for z/XC virtual machines.
