Error description

• Customer is suffering a solid ABEND 0C4 in DFHMQTRU in his CICS
  TS Ver.5.4. This problem has appeared after apply maintenance
  from RSU2004 to RSU2012.
  
  It seems the problem is CICS is trying to load a program named
  MQHRF2 that doesn't exists and this provokes a PGMIDERR.
  additional symptoms:
  DFHAP0001 applid An abend (code 0C4/AKEA) has occurred at
            offset X'00008102' in module DFHMQTRU.
  The program check occurs when we are attempting to put out
  trace entry:
  AP A0B8 - TID_MQTRU_CONV_ERR_ABLK Data conversion error,
  The failing instruction is LG      R7,X'B8'(,R13)
  due to R13 containing an invalid address.
  In CICS trace
  it shows DFHMQTRU linked to program MQIMSVS, but the program
  was not found, causing the LINK to fail with a Program ID ERROR.

  An 0C4 abend occurs in DFHMQTRU after an MQ data conversion
  attempt has failed.
  A typical scenario is an MQGET with get message option: convert
  and a 1 byte buffer. This  MQGET returns the length of the
  message and a subsequent MQGET is issued specifying a correct
  buffer length.

• UI71284 UI71286 UI71285
  Code has been added in DFHMQTRU to disable interest in an
  environment switch around the calls to the conversion exit, to
  avoid save area corruption.
