OA69093: ABEND0C4 IN DSNWAAPI CAUSED BY RESIDUAL IFCARA64 FLAG IN IFCA INITIALIZED BY IZDDCMDI

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• The ABEND0C4 occurs in DSNWAAPI because the caller provides an
  incorrectly initialized IFCA control block, causing the IFCARA64
  flag to be set when it should not be. As a result, DSNWAAPI
  interprets the return area using the wrong addressing format and
  abends when attempting to store data. The issue is caused by the
  caller not clearing the IFCA before setting its fields, leaving
  residual data that leads to an incorrect IFCARA64 value. Proper
  initialization of the IFCA resolves the problem.

Problem summary

• ****************************************************************
  * USERS AFFECTED: All ZDLA 320 users.                          *
  ****************************************************************
  The IFCA is allocated and utilized within IZDDCMDI; however,
  it is not fully initialized before use.
  As a result, certain fields including the IFCARA64 bit
  remain uncleared between successive calls.
  This leads to inconsistent behavior, as the failure
  pattern depends on whatever residual data
  was previously present in the allocated storage.
  

Problem conclusion

• Initialized the IFCA flag to resolve the flag in module IZDDCMDI
