By default, the PingDirectory server retains replicas for every server that has been part of a given topology. Over time, this can lead to an accumulation of obsolete replicas in your topology, which can increase the complexity of replication and negatively impact reliability.
To purge these obsolete replicas by default, you can set the
replication-purge-obsolete-replicas global configuration
If you set replication-purge-obsolete-replicas to
you must make this change on all server replicas, including new replicas as they
are added. Failure to do so could cause replicated servers to communicate an
inconsistent state across the topology. An inconsistent state can lead to a
replication-missing-changes alert and a server lockdown
because of the missing replication changes.
dsconfig set-global-configuration-prop, as in the following example:
bin/dsconfig set-global-configuration-prop \ --set replication-purge-obsolete-replicas:true
