  ****************************************************************
  IMS High Performance Image Copy breaks DBRC RECON data sets when
  the image copy job and DBRC RECON reorganization are running at
  the same time.
  
  IMS HP Image Copy uses DBRC API and IMS modules for accessing
  DBRC RECON. For DBRC API, IMS HP Image Copy allocates RECON data
  sets dynamically by its logic before issuing DBRC API
  FUNC=STARTDBRC. When using IMS module for updating DBRC RECON,
  RECON data sets are allocates in IMS module dynamically.
  
  But if IMS module is called between FUNC=STARTDBRC and
  FUNC=STOPDBRC of DBRC API, IMS module regards RECON data sets
  are allocated in address space by JCL allocation, and can not
  receive DBRC Loss Notification.
  
  The pair of RECON data sets are switched by DBRC RECON
  reorganization, and but IMS module does not know new pair and it
  updates old pair. As the result, the data in DBRC RECON is
  conflict and it can not accessed by other processes.
  
  IMS HP Image Copy does not use IMS module and DBRC API at the
  same time. DBRC access of DBRC API and IMS module in IMS HP
  Image Copy job are serialized.
  

Problem conclusion

• Following macros and modules have been modified that IMS HP
  Image Copy serializes DBRC RECON access from IMS modules and
  DBRC API for getting DBRC loss notification correctly.
