How a DH Is Restored

Understanding how the dmsmgr utility restores a DH helps you diagnose any problems that may occur during the restoration process.

The following process describes how dmsmgr restores a DH:

  1. dmsmgr removes the existing DH.
  2. dmsmgr copies the backup DH files from the location that you specified into the DH directory.
  3. dmsmgr subscribes the DH to the DMS with an offset value equal to the last global offset stored in the backup files.
  4. dmsmgr clears the out of sync flag on the DH.
