PK03509: ABEND0C4 IQCXLEVS WHEN Z/OS IGVINITGETMAIN IS ENABLED.

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• ABENDS0C4 IQCXLEVS when z/OS IGVINITGETMAIN is enabled.
  IGVINITGETMAIN is a z/OS diagnostic test tool that initializes
  storage obtained by a program to values other then zero.  In
  this case with QCF, the abend0c4 is due to storage not be
  cleared to x'00' (zero) when it is obtained.  Normally it is
  zero, but in this case it is changed by the tool, therefore
  the abend.
  

Local fix

• Do not run QCF with IGVINITGETMAIN enabled.
  

Problem summary

• ****************************************************************
  * USERS AFFECTED: All users of QCF. This APAR prevents QCF     *
  *                 from abending with 0C4, because a storage is *
  *                 referenced or used without first beeing      *
  *                 initialized or set by the programs.          *
  ****************************************************************
  * PROBLEM DESCRIPTION: QCF has been tested with a diagnostic   *
  *                      test tool named IGVINITGETMAIN. Tests   *
  *                      showed that in some cases storage is    *
  *                      used without first beeing initialized   *
  *                      or set by programs. This results in 0C4 *
  *                      Other symptoms can occur and  they      *
  *                      are unpredictable.                      *

  * RECOMMENDATION:                                              *
  ****************************************************************
  The programs have been changed to initialize obtained working
  storage.
  

Problem conclusion

• This APAR prevents QCF from abends, caused by not initialized
  or initially set program storage.
