PH35573: UPDATES TO THE KNOWLEDGE CENTER FOR THE DFHZC2426 E MESSAGE

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• When an error occurs that results in a DFHZC2426 E message a
  DFH2426 message is displayed on the terminal. The DFH2426
  message predates the DFHZC2426 message and has been
  output at terminals going back to CICS Version 1.
  .
  This APAR is to update the Knowledge Center entry for DFHZC2426
  to note that DFH2426 is output at the terminal and to improve
  the message explanation. The User Response for DFHZC2426
  currently states:
  .
  ' If the node is out of service, the master terminal operator
  should place the node back into service.'
  .
  It does not say anything about checking the TTISTATUS. A common
  cause of the DFHZC2426 message being put out is the terminal
  associated with the error message has a TTISTATUS of NOTTI. The
  TTISTATUS specifies whether the terminal is to be available for
  use by transactions that are initiated from this terminal.
  .
  The APAR would add explanation that a TTISTATUS of NOTTI
  indicates the TERMINAL is receive only and advise that the
  TTI attribute in the TYPETERM definition should be checked.

Local fix

• Set TTI=YES or TTISTATUS(TTI) on the terminals who are
  incurring the DFHZC2426E message

  *                      on the Knowledge Center does not        *
  *                      contain enough information to assist    *

  ****************************************************************
  The explanation for Message DFHZC2426 does not offer clear
  enough advice on how to resolve the error condition it was
  issued for.
  Additionally it includes a suggestion to research the meaning of
  sense data, which can be confusing if there is no sense data
  present in the message text.

Problem conclusion

• DFHZC2426 has been amended to make the explanation clearer.
  
  IBM Documentation for CICS TS for z/OS 5.6 will be updated as
  follows for message DFHZC2426:
  
  Explanation
  
  Input was received from a node that is identified as either
  output-only or as permanently out of service. CEMT INQUIRE
  TERMINAL(termid) returns a TTISTATUS of NOTTI for an output-only
  node. If any sense data appears in the message, see message
  DFHZC2400 for its meaning.
  
  System action
  
  For an output-only node, message DFH2426I is sent to the node.
  All outstanding send and receive requests are purged. If a task
  is attached, it is abnormally terminated with a transaction
  dump.
  
  User response
  
  If the node is out of service, issue CEMT SET TERMINAL(termid)
  INSERVICE from another terminal to place the node back into
  service.
  If the terminal is output-only, issue CEMT SET TERMINAL(termid)
  TTI from another terminal to allow transactions to be initiated
  from the node and check that TTI(YES) is specified in the
  TYPETERM definition used to install the TERMINAL.
