PH62523: YOU RECEIVE ERROR MESSAGE DFHXM0002 SEVERE ERROR CODE 0307 IN MODULE DFHXMRP

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• You are running CICS Transaction server 6.2..
  When you recycle the region, you receive the
  following errors:
  
  DFHXM0002 A severe error (code X'0307') has occurred in
          module DFHXMRP.
  The XM0002 occurs multiple times.
  
  
  DFHDM0105 Unsuccessful initialization of DFHXM domain.
          CICS will terminate.
  
  The 0307 error code is issued when trying to add a
  transaction recovered from the catalog, and this fails.
  It fails trying to restore a protected transaction-
  XMXD_TRANDEF_PROTECTED.
  The XM0002 is occurring due to trying to replace transaction
  CATR and it is marked not replaceable.
  That APAR moved the hard-coded definition of "category 3"
  transactions to be earlier in CICS startup, before
  transaction definitions are restored from the catalog.

  CICS has been running with the DFHCOMPJ Compatibility group.
  The region is restarted with a WARM start.
  XM domain calls the CC domain to restore transaction
  definitions from the CICS catalog.
  Conflict between the DFHCOMPJ transaction definitions and
  definitions provided by the XM domain cause messages
  .
