Error description

• Abend08B RSN00910022 msgCSV031I RC24 RSN26110FF6
  toleration missing on z/OS 2.2 and 2.1
  
  When a program object built by the z/OS 2.3 Binder is
  reprocessed on an earlier release of z/OS (for example, via
  some COPY tools that invoke the binder with INTENT=ACCESS),
  the copied program object is incorrectly re-built with two
  initial load segments.
  
  The re-built program object will fail to load with the
  following message / abend:
    CSV031I LIBRARY ACCESS FAILED FOR MODULE mmmmmmmm, RETURN CODE
            24, REASON CODE 26110FF6, DDNAME dddddd
    DUMP TITLE=IEWLRECV - LINEAR FORMAT PROGRAM MNGT -- ABEND
         0008B 000 REASON 00910022
  
  The Binder at HPM77B0 made a change in the internal format of
  the segment table.  This change was not recognized by previous
  releases, causing the re-built segment table to contain invalid
  data.
  
  Verification Steps:
   - program object was built fresh on z/OS 2.3,
   - later the program object was copied on z/OS 2.2 or 2.1 by an
      application that invoked the Binder APIs instead of IEBCOPY,
   - Abend08B results when trying to load / execute the program
      object.

Local fix

• option 1: If possible, invoke the (OEM) COPY job on the z/OS 2.3
  system which will allow the HPM77B0 binder to correctly process
  the PO for execution on previous releases.
  
  option 2: If BOTH the source and target of the copy is a PDS/e,
  you may choose to invoke IEBCOPY on either release of z/OS as it
  does not invoke the binder when source and target dataset type
  is the same.
  

Problem summary

• ****************************************************************
  * USERS AFFECTED: Those using the pre z/OS 2.3 binder API with *
  *                 INTENT=ACCESS to reprocess a program object  *
  *                 (PO) built on z/OS V2R3.                     *
  ****************************************************************
  * PROBLEM DESCRIPTION: When a reprocessed PO (as described     *
  *                      above) is saved, and then executed,     *
  *                      ABEND0C4 may occur with a reason code   *
  *                      26110FF6.                               *
  ****************************************************************
  * RECOMMENDATION:                                              *
  ****************************************************************
  POs built on z/OS V2R3 may contain a class table which cannot be
  correctly processed by lower-level z/OS binder releases. During
  the INTENT=ACCESS processing, the binder needs to retain the
  containing segment ID of each class, but does not correctly do
  so in this case. ABEND0C4 may occur due to incorrect segment
  IDs.
  

Problem conclusion

• Toleration support has been provided in all supported lower
  releases of the z/OS binder.
