Error description

• You are attempting to run the Discovery Library Adapter using
  the IBM Supplied samples. You immediately receive an 0C4 abend
  code with the following in your job log:

  The problem is with program reentrancy and APF authorization.
  The IBM-supplied sample JCL has the following datasets in the
  STEPLIB DD:
  .
  //STEPLIB  DD   DISP=SHR,DSN=&CPSMHLQ..SEYULOAD
  //         DD   DISP=SHR,DSN=&CPSMHLQ..SEYUAUTH
  //         DD   DISP=SHR,DSN=&CICSHLQ..SDFHAUTH
  //         DD   DISP=SHR,DSN=&CICSHLQ..SDFHLOAD
  .
  The EYU9XDDA load module is in the SEYULOAD dataset. Because the
  STEPLIB contains some APF authorized datasets as well as
  un-authorized datasets, MVS will consider the whole
  concatenation of datasets to be not APF authorized, and will
  load the EYU9XDDA load module into subpool 251 storage.
  .
  If you have made the SEYULOAD and SDFHLOAD datasets APF
  authorized on your system, then MVS will load the EYU9XDDA load
  module into subpool 252 storage, which is write-protected.
  .
  Load module EYU9XDDA is linkedited with the RENT parm,
  indicating it is REENTRANT. However, some sections of the code
  do not adhere to the restrictions of being a reentrant program,
  resulting in an S0C4 abend.
  

Local fix

• Remove APF authorization from the SDFHLOAD and SEYULOAD
  datasets, or add an additional "dummy" load library that is not
  APF authorized to the STEPLIB concatenation.

  * RECOMMENDATION: After applying the PTF that resolves this    *
  *                 APAR, EYU9XDDA should be rerun, pointing     *
  *                 to the libraries updated by the PTF.         *
  ****************************************************************
  When a reentrant (RENT) and reusable (REUS) module is executed
  from an APF authorized library concatenation, it is loaded into
  store protected storage.  If the program attempts to modify
  itself, a S0C4 abend will occur.
  
  Program EYU9XDDA, which is neither reentrant nor reusable, has
  been invalidly distributed with the linkage editor RENT and REUS
  attributes.  This results in the S0C4 abend documented above
  when it is executed from an APF authorized library
  concatenation.
  

Problem conclusion

• The JCLIN for EYU9XDDA has been updated to remove the RENT and
  REUS attributes.
