Synchronizing Replicas


This chapter describes the process of synchronization. Synchronization uses the same export-transport-import procedure that is used during replica creation:

  1. Export: At one replica, a syncreplica (synchronize replica) command is invoked with the –export option. This creates a packet of data.
  2. Transport: The packet is sent to one or more other replicas.
  3. Import: At the other replicas, a syncreplica command is invoked with the –import option. This applies the changes in the packet to an existing replica.

The syncreplica command is optimized for performance; it creates a packet that contains only the information required to update the target replicas specified on the command line.
