PI78851: ABENDU2990 RSNC4C5C3A6 WHEN COMPRTN SPECIFIES KEY AND COMPRESSION ROUTINE IS USED

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• An ABENDU2990 RSNC4C5C3A6 may occur when an IMS COMPRTN
  specifies KEY
  and the segment data is compressed prior to being encrypting.
  When KEY
  is specified the compression routine is allowed to compress the
  sequence field in the segment, as well as any data following
  it. It is
  possible that the resulting compressed segment data will be
  shorter
  than the uncompressed sequence field, resulting in the
  validation code
  incorrectly failing the request. The validation code should not
  verify
  that the data to be encrypted is longer than the sequence field
  length
  when compression is also being performed and KEY has been
  specified.
