Replication Attributes under cn=replica, cn="suffixDN", cn=mapping tree, cn=config
Parameter
Default Value
Syntax
Example
2.3.7.7. 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 entriess
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.
This attribute specifies the interval, in seconds, to perform internal purge operations on an entry. When
setting this attribute, ensure that the purge delay is longer than the longest replication cycle in the
replication policy to preserve enough information to resolve replication conflicts and to prevent the
copies of data stored in different servers from diverging.
Parameter
Entry DN
Valid Range
Default Value
Syntax
Example
2.3.7.8. nsDS5ReplicaReferral
This multi-valued attribute specifies the user-defined referrals. This should only be defined on a
consumer. User referrals are only returned when a client attempts to modify data on a read-only
consumer. This optional referral overrides the referral that is automatically configured by the consumer
by the replication protocol.
