Red Hat Directory Server 8.0 Configuration, Command, and File Reference
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
3.7.7. nsDS5ReplicaPurgeDelay
This attribute controls the maximum age of update operations and state information.
The Directory Server stores updates — operations like adds, modifies, and deletes — so that it
can replay those updates to other replicas. It keeps those updates in the changelog and as
state information in the main database as change sequence numbers (CSN) and tombstone
entries for some period of time after they have been replayed, in case a replica needs to be
brought up to date without having to do a full reinitialization. An internal Directory Server
housekeeping operation periodically removes updates and state information older than the
value of this attribute (in seconds). Not every update may be removed. 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. This attribute specifies the period of time in seconds after which internal
purge operations are performed on the changelog. When setting this attribute, ensure that the
purge delay is longer than the longest replication cycle in the replication policy to avoid incurring
conflict resolution problems and server divergence.
Parameter Description
Entry DN cn=replica, cn=suffixDN, cn=mapping tree,
cn=config
