PI42277: IEW2146S CONFLICTING INPUT SPECIFICATIONS AFTER APPLICATION ERROR DRIVES DEBUG INFRASTRUCTURE UNDER CICS

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• With COBOL v5, debug related data is stored in a deferred load
  segment, which is brought into memory as required, for example
  to produce a CEEDUMP upon an application error. Under CICS, a
  CICS INQUIRE PROGRAM is used to locate programs of interest and
  load their debug data if compiled with such, but that API
  returns a zero return code if a program is in the PPTE but is
  not loaded, and additional checking is required to determine
  that fact.
  
  That additional checking was not present, as a consequence the
  _iew_includeName() binder API was driven with a bad parameter,
  leading to the IEW2146S message.
  Additional symptoms: S80A abend, S878 abend, IEW2974T message,
  IEW4000I message.
  By reviewing a S80A abend dump, we see the CICS region is
  short on MVS storage. Break down the storage, we can see
  lots of storage was allocated to SP/K: 0/8 with size x'8000'.
  Browsing those chunks of storage, we see they all have
  eyecatcher 'IEWBSAD' in the begining.
  

Local fix

• Compile with NOTEST(NODWARF) or resolve/handle application
  errors

  ****************************************************************
  While generating a CEEDUMP, the COBOL runtime invokes CDA to get
  the debug information to be formatted and printed. One of the
  input to the CDA API is the DD name of the module. The COBOL
  runtime issues the CICS INQUIRE PROGRAM command for the PROGRAM
  name and LIBRARY name in order to construct the DD name.
  However, when the CICS command encounters a program in the PPTE
  that's not loaded, the command is still considered successful
  with a zero RESP code, but the LOADPOINT address used to
  validate against the entry point address is set to NULL instead.
  The COBOL runtime only checks for zero RESP code, but fails to
  make sure the LOADPOINT address returned is not a NULL.
  

Problem conclusion

• The COBOL runtime is corrected to check for valid output
  returned from the CICS INQUIRE PROGRAM command before proceeding
  to construct a DD name for use with the CDA API.
