The following correspondences between the source and target systems apply to linking data from a HiRDB to a mainframe database (XDM/RD E2):

• Correspondence between the source Datareplicator and the source HiRDB
  Source HiRDB (single server) to source Datareplicator = 1 to 1
  Source HiRDB (parallel server) to source Datareplicator = 1 to n
  
• Correspondence between Datareplicator and XDM/DS
  Source Datareplicator to XDM/DS = 1 to m
  Source Datareplicator to XDM/DS = 1 to 1
  
• Correspondence between the source database and XDM/DS
  See the VOS3 XDM/DS manual.
  

The following figure shows the configurations of the source and target systems for linking data from a HiRDB to a mainframe database (XDM/RD E2).
