  This APAR includes following APAR fix from IMS High Performance
  Image Copy for z/OS version 4 release 1:
  
  PM47368 fixes following problems of HP Image Copy Recovery
  function:
  
  1. When either DFSUCUM DD or DFSULOG DD cards are not specified
     in the running JCL of HP Image Copy Recovery function with
     DBRC=N, HP Image Copy ends with RC=8 and MSG DFS301A
     ( MSGDFS301A ).
  
  2. If the associated change accumuration and log data set are
     not found in the DBRC RECON and both DFSUCUM DD and DFSULOG
     DD cards are not specified in the running JCL of HP Image
     Copy Recovery function with DBRC=Y, HP Image Copy ends with
     RC=8 and MSG DFS301A ( MSGDFS301A ).
  
  3. If image copy data set are not provided in the HP Image Copy
     Recovery function with DBRC=N, HP Image Copy ends with RC=16
     and MSG FABJ3941E ( MSGFABJ3941E ).
  

Problem conclusion

• FABJDALC has been modified as follows:
  - To allocate dynamically DFSUCUM and DFSULOG DD as DUMMY when
    DBRC=N is specified, even if ICDALLOC=N or STACK keyword is
    specified.
  - Not to allocate dynamically null file as DFSUDUMP DD.
