• After Datareplicator initialization, copy the duplexing control file to the Datareplicator directory of the corresponding standby server. There is no need to copy the duplexing control file in the following cases:
  
  • A HiRDB/Parallel Server is used with a system switchover configuration and the executing back-end server is located on the standby host.
    The duplexing control file is created automatically on the back-end server in the executing system.
    
  • There is no change to the duplexing control file during the second or a subsequent system switchover processing.
• There is no need to copy to the standby system files whose extension is .mf. These are work files Datareplicator creates when duplex files are used. Do not delete these files while Datareplicator is running.

If an error occurs in a duplexed file, the file must be recovered. For details, see 9.1.6 Handling of file errors during file-duplexed operation.
