PH47563: CSQX112E CSQXDISP DISPATCHER PROCESS ERROR CSQFSAMG +00B7A 23/03/20 PTF PECHANGE

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• MQ Development finds that a hostname lookup failed for a
  specified LOCLADDR while the associated channel was
  attempting to start. This caused the CHIN to build a CSQX235E
  message to report this, and the 0C4 abend occurred while
  building this message. The length of the first line of the
  message was long enough that it needed to be split over 2
  lines, and it's in this processing where the problem lies. An
  invalid combination of flags in the CHINIT message control
  block (xMcb) results in a message LLZZ being interpreted as a
  buffer address. This problem was introduced by PTF UI68821.
  

Local fix

• Ensure LOCLADDR value is resolvable.

  ****************************************************************
  When starting a channel with an invalid LOCLADDR value thats
  length is greater than 25 characters, errors are seen as part of
  printing the message CSQX235E in the channel initiators joblogs
  to report the invalid LOCLADDR value.
  
  At V910 an S0C4-00000011 abend in seen in CSQFSAMG in the
  channel initiator address space caused by a regression
  introduced by PTF UI68821.
  
  At V920 & V930 the message CSQX235E is incorrectly formatted as
  the LOCLADDR value printed with the message fails to be moved to
  a new line and is thus incorrectly truncated.
  

Problem conclusion

• At V910 the regression introduced by PTF UI68821 has been
  corrected so that the CSQX235E message is correctly printed to
  the channel initiators joblogs and the S0C4 abend is not issued.
  
  At V920 & V930 the formatter processing message CSQX235E has
  been corrected to utilise multiple lines to display the LOCLADDR
  value if its length is greater than 25 characters long and will
  not be truncated.
