A returns the set of directory servers participating in a replication topology. The specifies the replication servers whose configuration is periodically read to discover available replicas. org.opends.server.backends.proxy.ReplicationServiceDiscoveryMechanism ds-cfg-replication-server-discovery-mechanism ds-cfg-service-discovery-mechanism Replication domain group ID of preferred directory server replicas. Directory server replicas with this replication domain group ID will be preferred over other directory server replicas. Secondary server replicas will only be used when all primary server replicas become unavailable. All the server replicas will be treated the same. ds-cfg-primary-group-id Specifies the list of replication servers to contact periodically when discovering server replicas. ^.+:[0-9]+$ HOST:PORT A host name followed by a ":" and a port number. ds-cfg-replication-server The bind DN for periodically reading replication server configurations The bind DN must be present on all replication servers and directory servers, it must be able to read the server configuration. ds-cfg-bind-dn The bind password for periodically reading replication server configurations The bind password must be the same on all replication and directory servers ds-cfg-bind-password Interval between two replication server configuration discovery queries. Specifies how frequently to query a replication server configuration in order to discover information about available directory server replicas. ds-cfg-discovery-interval 60s
