PI79450: FPA ANALYZE AND FPO OPC TO ADD A NEW OPTION TO SUPPRESS SDEP POINTER ERROR MESSAGE THAT IS NOT AN ACTUAL POINTER ERROR

Obtain the fix for this APAR.

APAR status

• Closed as new function.

Error description

• When the IOVF portion is expanded by OAE, some SPCF pointers in
  root segments still point to the IOVF portion.  This is because
  some SDEP segments were being placed in the first part of
  the SDEP area, which was changed to the IOVF area by OAE. If
  FPA Analyze or FPO OPC was run against the area, one of the
  following error messages is issued:
   0108 SEGMENT AT RBA: xxxxxxxx (SEGCD: 01) HAS AN INCORRECT SDEP
        POINTER VALUE
   1005 Root segment contains invalid RBA for a SDEP segment.
  However, this is not an actual pointer error and does not cause
  any problem.
  
  FPA Analyze and FPO Online Pointer Checker is adding a new
  option to suppress the above SDEP pointer errors.

  ****************************************************************
  This APAR enables the FPA and the FPO to specify the severity
  level of the message that is issued when detecting an SDEP
  pointer that points to the IOVF portion.
  
  A new option SDEP_PTRIOVF_MSGLVL is provided.
  If SDEP_PTRIOVF_MSGLVL=INFORMATIONAL is specified, an
  information message is issued when an SDEP pointer that points
  to IOVF portion is detected.
  If SDEP_PTRIOVF_MSGLVL=NOMSG is specified, no message is issued
  when an SDEP pointer that points to IOVF portion is detected.
  If SDEP_PTRIOVF_MSGLVL=ERROR (default) is specified, a pointer
  error message is issued when an SDEP pointer that points to IOVF
  portion is detected. This is the same behavior as before.
  
  Following FPA functions support SDEP_PTRIOVF_MSGLVL option.
   - FPA Analyze
   - FPA Reorg
  Following FPO utilities support SDEP_PTRIOVF_MSGLVL option.
   - Online Pointer Checker
   - Online Expert Reorganization
  
  This APAR also handles followings.
  1. Add RBA value to the FPX0011E message.
  2. Avoid causing a loop when One step OPC fails a DL/I call.
  3. Avoid causing a hang when OPC detects a pointer that points
  to outside the DEDB area.
  4. Modify some FPO modules to prevent unnecessary L1 cache
  invalidations.
