PM54802: ABEND S66D-31 DURING CONTROLLER TASK INITIALIZATION IF RECOVERY(YES) SPECIFIED IN OPCOPTS AT Z/OS 1.13 OR HIGHER

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• When running a TWSz controller task (any release) under
  z/OS 1.13 or higher, and using the OPCOPTS parameter
  RECOVERY(YES), an abendS66D ( 66D - 31 ) is seen in the
  controller.
  Checking the dump, the abend is at IGX00027+150 on a call to
  TSO STACK service.  Abend S66D-31 means a TSO/E service that
  requires a TSO/E environment was invoked in a non-TSO/E
  environment.
  .
  Program EQQZMSGT + x'266', invokes the CALLTSSR macro to call
  the STACK service, which causes an immediate failure
  in IGX00027+x'150' - where an ABEND66D-31 is issued because this
  is not a TSO environment.
  .
  The same code worked correctly in z/OS 1.12 and lower.
  The abend can be taken even with RECOVERY(NO) coded
  .

  ****************************************************************
  A system abend 66D with RC=31 can occur at start time of a TWSz
  started task on a z/OS 1.13 system.
  

Problem conclusion

• The problem occurs because the TSO checks the LWALWA field
  that should contain the value '   LWA  ';
  since the TWSz builds its own LWA area, this field was not
  filled in with the above value.
