Chapter 2. Core Server Configuration Reference
82
Parameter Description
Entry DN cn=replica, cn=suffixDN, cn=mapping tree,
cn=config
Valid Values true | false
Default Value false
Syntax DirectoryString
Example nsDS5ReplicaLegacyConsumer: false
2.3.7.9. nsDS5ReplicaName
This attribute specifies the name of the replica with a unique identifier for internal operations. If it is not
specified, this unique identifier is allocated by the server when the replica is created.
NOTE
It is recommended that the server be permitted to generate this name. However, in
certain circumstances, for example, in replica role changes (master to hub etc.), this
value needs to be specified. Otherwise, the server will not use the correct changelog
database, and replication fails.
This attribute is destined for internal use only.
Parameter Description
Entry DN cn=replica, cn=suffixDN, cn=mapping tree,
cn=config
Valid Values
Default Value
Syntax DirectoryString (a UID identifies the replica)
Example nsDS5ReplicaName:
66a2b699-1dd211b2-807fa9c3-a58714648
2.3.7.10. nsDS5ReplicaPurgeDelay
This attribute controls the maximum age of deleted entries (tombstone entries) and state information.
The Directory Server stores tombstone entries and state information so that when a conflict occurs in a
multi-master replication process, the server resolves the conflicts based on the timestamp and replica
ID stored in the change sequence numbers.
An internal Directory Server housekeeping operation periodically removes tombstone entries
which are older than the value of this attribute (in seconds). State information which is older than
the nsDS5ReplicaPurgeDelay value is removed when an entry which contains the the state
information is modified.
Not every tombstone and state information may be removed because, with multi-master replication,
the server may need to keep a small number of the latest updates to prime replication, even if they are
older than the value of the attribute.
