PM62665: ABENDU0200 IN MODULE DFSECP20 DURING APPLICATION AIB CALL WHEN AIBLEN IS SET TO ZEROES

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• Processing an application AIB call, an ABENDU0200 may result if
  the AIBLEN is specified as zeroes.  A valid AIBLEN is required.
  The ABENDU0200 is not expected.  The application AIB call
  should have returned an RC104 RSN228.  Invalid AIBLEN for
  function.  DFSLIE20 should validate the AIBLEN before
  attempting to process the call.
  .
  With AIBLEN set to zeroes, the copy of the AIB to the KEY7 AIB
  results in nothing being copied.  The KEY7 AIB will have
  residual data from the previous application AIB call.  If the
  residual AIBOALEN in the KEY7 copy is too small for the data
  being returned, the ABENDU0200 will result.
  

Local fix

• Ensure a valid AIBLEN is specified

  * RECOMMENDATION: INSTALL CORRECTIVE SERVICE FOR APAR/PTF      *
  ****************************************************************
  When processing an application AIB call, module DFSLIE20
  does not check whether the AIBLEN specified is valid.  If
  the length is zero, the key 7 AIB will contain residual
  data.  This may result in the reported ABENDU0200.  The
  correct behavior is to return with error RC104 RSN228.
  

Problem conclusion

• GEN:
  KEYWORDS:
  
  *** END IMS KEYWORDS ***
  Validation code is added to DFSLIE20 to ensure that the
  input AIBLEN is valid before using it.  If the length is
  zero or negative, normal processing does not occur.
  Instead, the module returns with an AIB return code of
  104 and an AIB reason code of 228 to indicate a parameter
  length error.
  
  Modules changed
  ---------------
  DFSLIE20 -- Validate input AIBLEN.
