Changing the Replication Purge Delay

The replication changes database maintains a record of updates, which might or might not have been replicated. The replication purge delay is a property of the replication server, and specifies the period of time after which internal purge operations are performed on the replication changes database.

How Replication Changes Are Purged

Any change that is older than the purge delay is removed from the replication changes database, irrespective of whether that change has been applied. The default purge delay is one day. If the replication changes database is backed up less frequently than the purge delay, changes will be cleared before the changes database has been backed up. Changes can therefore be lost if you use the backup to restore data.

To Change the Replication Purge Delay

  1. (Optional) Display the current value of the replication purge delay.
    $ dsconfig -D "cn=directory manager" -w password -n get-replication-server-prop \
      --provider-name "Multimaster Synchronization" --advanced \
      --property replication-purge-delay
    Property                : Value(s)
    replication-purge-delay : 1 d 
  2. Change the purge delay.

    The following command changes the purge delay to one week:

    $ dsconfig -D "cn=directory manager" -w password -n set-replication-server-prop \
      --provider-name "Multimaster Synchronization" --set replication-purge-delay:1w
