PI87458: DFHWB0002 CODE X'FF67' DUE TO CONTAINER_ERROR

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• Customer is receiving DFHWB0002 CODE X'FF67' due to
  CONTAINER_ERROR.  The reason for the CONTAINTER_ERROR is due to
  INVALID_POOL_TOKEN on the previous PUT_CONTAINER command
  against container SERVER_HDR_OUT .  The CONTAINER_POOL_TOKEN is
  zeros, thus invalid.
     This stems from  USER_NOT_AUTHORISED being realized early in
  the transaction attach processing.  Message DFHWB0361 is
  produced and the customer's web error program (DFHWEBP) is
  called.  The web error program does a lot of processing
  including extract of certificate and writes of messages to
  CSMT.  Eventually, the web error program issues an
  EXEC CICS WEB WRITE HTTPHEADER command.  This causes DFHWBQM to
  issue a PUT_CONTAINER command to SERVER_HDR_OUT with the null
  pointer to CONAINER_POOL_TOKEN.
     There is no container pool token due to the CREATE_POOL
  processing not being done before the API calls. This is
  normally done by DFHWBQM early at attach time but seems to be
  bypassed when the USER_NOT_AUTHORISED is realized.

Problem summary

• ****************************************************************
  * USERS AFFECTED: All CICS Users.                              *
  ****************************************************************
  * PROBLEM DESCRIPTION: Severe error 'FF67'x in DFHWBQM when    *
  *                      WEB WRITE HTTPHEADER is used within     *
  *                      DFHWBEP                                 *
  ****************************************************************
  CICS is processing a WEB request and attempts to use the URIMAP
  transaction directly.  The transaction is attached and a
  security check is done this check fails meaning DFHWBEP needs
  to be called to return an error to the client.  DFHWBEP calls
  EXEC CICS WEB WRITE HTTPHEADER which fails with a 'FF67'x
  because the container pool for the headers has not been
  created, meaning the internal token wrb_respository_token has
  not been initialized.
  

Problem conclusion

• DFHWBXM has been updated to initialize the internal token prior
  to the call to DFHWBEP.
