PI96545: WRONG APPLICATION PROGRAM EXECUTED WHEN USING CICS CLOUD/ PLATFORM WITH PUBLIC/PRIVATE LIBS.

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• CICS TS 5.4
  In one of our set-ups to test with CICS TS (5.4)
  cloud-enabled applications, the following characteristics apply:
  .
    program PRO37 is defined as an entry point of application
  prDEF_Application, which is defined with another private library
  containing load module PRO19;
    program PRO38 is defined as an entry point of application
  prGHI_Application, which is defined without any
  private library;
    all programs PRO37 and PRO38 both perform an
    EXEC CICS START TRANSID(TR19);
  when PRO38 runs ans STARTs TRANID(TR19), program PRO19 is
  incorrectly loaded from the private library version instead
   of the PUBLIC library.

  * PROBLEM DESCRIPTION: A wrong program may get driven in a     *
  *                      multi-version program environment.      *
  ****************************************************************
  In a CLOUD enabled CICS platform, it is possible to have
  Multi-versioning of application programs.  These are different
  versions of the same program name.  It is also possible to have
  a program with the same name that does not have versions at all.
                                                                .
  Usually, these 2 types of programs (VERSION'd and NON-VERSION'd)
  would be referenced internally by CICS on PRIVATE and PUBLIC
  PPTE chains respectively.  However, a path exists in DFHPGPG
  where a VERSION'd copy of a program is driven when it was
  intended to drive the NON-VERSION'd copy.  The opposite can also
  occur.
  

Problem conclusion

• DFHPGPG has been amended to correct the aforementioned problem
  scenario.
