Types of replicas
• Master replica. Although many replicas can exist in the Directory, only one is the
master replica. Use it to create a new partition in the Directory database, or to read
and update Directory information, such as adding or deleting objects.
• Read-write replica. Use to read or update Directory information (such as adding
or deleting objects).
• Read-only replica. Use to view, but not to modify, Directory information.
Synchronization
To maintain their fault tolerance, a partition’s replicas must be periodically
updated, or synchronized.
When changes are made in one replica, synchronization ensures that those
changes are made in all other replicas of that partition, so that each
partition’s replica contains the same data as the other replicas.
Network supervisors control how often replica synchronization occurs. The
more frequently synchronization occurs, the more consistent the replicas are.
See “Managing the NetWare Directory Services Database” in Supervising
the Network.
Use the Partition Manager utility to manage partitions, replicas, and
synchronization.
