PH48753: DFHPI0002 CODE X'0507' DURING WBCL_CLOSE_SESSION DUE TO INVALID SESSION TOKEN 22/12/09 PTF PECHANGE

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• When the WBCL CLOSE_SESSION domain call is made by DFHPITH in
  this particular code path wbcl_session_token is populated from
  register 2.  At the time of the call the bottom-half of register
  2 contains the length part of the token, however the top-half is
  zeros rather than an address.
  .
  At the start of the logic for dfhpith_capture_web_failure, a STM
  saves registers 14 through 12 into a register save area.  This
  correctly saves the full 64 bit token in register 2.  However
  upon return from the PGCR GET_CONTAINER call in
  dfhpith_issue_requester_error_msg, only the bottom half of the
  registers is restored.  This is ok for all registers except
  register 2 where we inadvertently lose the address.  As a result
  the problem occurs when the CLOSE_SESSION domain call is made.

  * PROBLEM DESCRIPTION: Message DFHPI0002 A severe error        *
  *                      (code X'0507') has occurred in module   *
  *                      DFHPITH.                                *
  ****************************************************************
  An EXEC CICS INVOKE SERVICE command is issued which fails due to
  an SSL issue.  DFHPITH subsequently makes a WBCL CLOSE_SESSION
  domain call to clean up but passes a session token of zero
  which causes a DFHPI0002 severe error.
  

Problem conclusion

• UI80274 UI80278
  DFHPITH has been changed to ensure the session token is no
  longer corrupted.
