PM77736: ABENDAEXZ EXECUTING WSACONTEXT GET API

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• Customer is using the WSACONTEXT GET interface. When attribute
  EPRTYPE(TOEPR) is coded, there are three scenarios associated
  with IsReferenceParameter that cause ABENDAEXZ.
  .
  1. When IsReferenceParameter starts with capital 'T'
     For example:
  <tag:TagId wsa:IsReferenceParameter="True">xxxxxxxxx</tag:TagId>
  .
  2. When IsReferenceParameter contains child tags
  or child tags contain IsReferenceParameter
           (regardless if case is 'True' or 'true')
     For example:
  <tag:TagId wsa:IsReferenceParameter="true"
                                 xmlns:tag="http://url.xxxx.com">
  </tag:TagId>

  * PROBLEM DESCRIPTION: AEXZ abend after issuing EXEC CICS      *
  *                      WSACONTEXT GET.                         *

  ****************************************************************
  A service requester includes WS-Addressing reference parameters
  in a request to CICS. DFHPIA1 builds an endpoint reference and
  stores it in the DFHADDR-CXT-REQ container.
  If a reference parameter is greater than 255 bytes it is
  truncated but space is allocated for the full length in the
  container. This results in invalid data being saved.
  When an EXEC CICS WSACONTEXT GET EPRTYPE(TOEPR) is issued,
  DFHPIAD extracts the reference parameters from DFHADDR-CXT-REQ.
  Validation of the parameters fails because of the data
  truncation. DFHPIAD returns an ADDRESSING_EXCEPTION and this
  leads to an AEXZ abend.
  

Problem conclusion

• CICS is changed to prevent truncation of WS-Addressing
  reference parameters sent by a service requester.
