OA48001: WAIT040 DUE TO ABENDC0D UNDER NIP RIM IEAVNPD7

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• IAXMH issues AbendC0D RSNF3333333 because it is unable to obtain
  a quad frame during NIP.  This results in WAIT STATE 040.  This
  is occurring because the quad frame area has not been built.
  OA44207 removed code in IAXMT that is preventing the quad frame
  area to be built, if REAL= IEASYSxx parameter is set to REAL=0.
  
  This occurs on systems with a small assignment of online real
  storage, 1024MB or less with increment size of 512MB, 512MB or
  less with increment size of 256MB, 256MB or less with increment
  size of 128MB.
  
  
  PE Information:
  User's Affected: Users with OA44207 installed, and IPLing
  with less than 2G of storage.
  UA74198(HBB7790)
  
  User Impact:
  Systems defined with less than 2G of storage and IEASYSxx
  parmlib REAL=0 coded may fail to ipl.  For machines with 256M
  increment size, the failure will occur with less than 768M
  online.  For machines with 512M increments, the failure is seen
  with less than 1.5G online.  APAR OA44207 fixed the problem it
  reported but introduced a new problem described above.  If
  OA44207 is already installed and 2G or more of storage will
  always be available, there is no need to remove the PTFs.
  

Local fix

• Add more real storage such that the following exists:
  If your storage increment size is 128MB, 256MB, or 512MB, ensure
  at least 3 storage increments are online at IPL.

  ****************************************************************
  Module IAXMT selects the real storage location for the quad
  frame area.  The system was IPLed with only one storage
  increment, which was marked as preferred storage.  The search
  routine was only looking for non-preferred storage and failed
  to create a quad frame area.  The subsequent quad frame
  request by IAXMH could not be satisfied resulting in the
  ABENDC0D and WAIT040.
  

Problem conclusion

• Code in the quad area selection routine is changed to select a
  preferred area if no non-preferred area is available.
