APAR status

• Closed as program error.

Error description

• If PRF is loaded from APF authorized library and CHKPINT>0 is
  specified, job will abend after CHKPINT seconds have elapsed
  (instead of displaying IRT090I).

Problem summary

• ****************************************************************
  * USERS AFFECTED: All Users of Program Restart Facility V2R2   *
  *                 that run PRF from an APF-authorized          *
  *                 concatenation and utilize CHKPINT            *
  *                 processing.                                  *
  ****************************************************************
  * PROBLEM DESCRIPTION: When PRF is loaded from an              *
  *                      APF-authorized concatenation, it is     *
  *                      loaded into a storage subpool which     *
  *                      requires that a program be in key 0     *
  *                      before the storage can be modified. PRF *
  *                      operates in the user application key.   *
  *                      The CHKPINT specification causes logic  *
  *                      to execute which keeps track of the     *
  *                      time between program checkpoints by     *
  *                      setting a timer. When the time interval *
  *                      expires, a STCKCONV macro is issued to  *
  *                      format the result of a TIME macro used  *
  *                      to format the amount of time since the  *
  *                      last checkpoint was taken. The STCKCONV *
  *                      macro was not coded in a re-entrant     *
  *                      fashion, which causes the macro         *
  *                      invocation to use an in-line parameter  *
  *                      list. Because the module was loaded     *
  *                      into a storage subpool which requires   *
  *                      the program to be operating in key 0    *
  *                      before storage in that subpool can be   *
  *                      modified, the S0C4 occurs.              *
  ****************************************************************
  * RECOMMENDATION: Apply the PTF that corrects this APAR.       *
  ****************************************************************
  The PRF module in question was not coded to be re-entrant, but
  was linked as re-entrant. This caused the module to be loaded
  into a storage subpool that is restricted for update to
  programs running in key 0, when the module is loaded from an
  APF-authorized concatenation.
  

Problem conclusion

• The PRF module in question has been modified to be re-entrant.
