R
Rename right
A Directory Services object right that grants the right to change the name of
an object, in effect changing the naming property.
See “Rights.”
Replica
A copy of a Directory partition.
For a NetWare Directory Services database to be distributed across a
network, the database must be stored on many servers. Rather than have a
copy of the whole database on each server, replicas of each partition are
stored on many servers throughout the network.
You can create an unlimited number of replicas for each partition and store
them on any server.
Purpose
Replicas serve two purposes:
• To eliminate any single point of failure.
For example, if a disk crashes or a server goes down, a replica on another server
can still authenticate users to use the network and can provide information on
objects in that partition.
With the same information distributed on several servers, you aren’t dependent
on any single server to authenticate who can use the network.
You can store a replica of one partition with a replica of another partition on the
same server.
Replication of the Directory does not provide fault tolerance for your file
system. Only Directory information about objects is replicated.
• To provide faster access to information for users across a WAN link.
For example, if a WAN link is used to access information, you can decrease
access time and network traffic by placing a replica containing the needed
information on a server that users can access locally.
Distributing replicas among servers lets you access information more quickly
and reliably because the information comes from the nearest available server.
