PH17917: DFHME0124 APPLID TD IS UNAVAILABLE FOR WRITING MESSAGES DFHSO0145 AND DFHSO0146 TO TD QUEUE XXXX

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• CICS TS Ver.5.4 is trying to bring up and it is failing to
  initialize SSL. Reviewing the regions Joblog you see
  the following messages:
  
  +DFHME0124 TD is unavailable for writing message DFHSO0145 to
             TD queue CSOO.
  +DFHME0124 TD is unavailable for writing message DFHSO0146 to
             TD queue CSOO.
  
  The situation is that DFHSOSE is sending these messages of
  SO0145 and SO0146 to the specified transient data queue. But
  the TD queue is not available for writing because it is not
  initialized yet. Also, this region contains the DD statement
  for DFHCXRF which CICS uses while the TD is initializing. But,
  being that the queue is not available the request should have
  been redirected to CXRF but that is not happening.
  
  The queue CXRF is only used when TD domain is initializing. It
  gets used as the destination in place of all CICS defined TD
  queues. The situation we have here is that TD hasn't even
  started initialization so message domain cannot call it at all.
  This means CXRF is unable to be used as an alternate
  destination.
  

Local fix

• Remove the legacy cipher suites

  ****************************************************************
  A TCPIPSERVICE was recovered from the CICS global catalog and
  installed during a warm start of CICS. This resource specified a
  cipher list that included some invalid ciphers. CICS removed
  these and attempted to write messages DFHSO0145 and DFHSO0146 to
  the CSOO Transient Data (TD) queue to give details of the
  ciphers affected. However TD initialisation had not started and
  DFHME0124 messages were issued to report that the TD queue was
  not available. As a result, no information was given about which
  ciphers had been removed.
  
  Keywords: SO0145 SO0146
  

Problem conclusion

• CICS has been changed so that messages DFHSO0145 and DFHSO0146
  are sent to the console if TD has not been initialised.
