A comprises of several directory servers sharing the same synchronized set of data. ds-cfg-replication-domain top Specifies the addresses of the Replication Servers within the to which the directory server should try to connect at startup time. Addresses must be specified using the syntax: hostname:port ^.+:[0-9]+$ HOST:PORT A host name followed by a ":" and a port number. ds-cfg-replication-server Specifies a unique identifier for the directory server within the . Each directory server within the same must have a unique server ID. A directory server which is a member of multiple may use the same server ID for each of its configurations. ds-cfg-server-id Specifies the base DN for which to replicate changes. In most cases, it should be set to the user data suffix for the directory server. ds-cfg-base-dn Specifies the window size that the directory server uses when communicating with Replication Servers. 100 ds-cfg-window-size Specifies the heart-beat interval that the directory server uses when communicating with replication servers. The directory server expects a regular heart-beat coming from the replication server within the specified interval. If a heartbeat is not received within the interval, the Directory Server closes its connection and connects to another replication server. 1000ms ds-cfg-heartbeat-interval Specifies the behavior of the directory server if a write operation is attempted on the data within the when none of the configured replication servers are available. reject-all-updates Indicates that updates should be accepted even though it is not possible to send them to any replication server. Best effort is be made to re-send those updates to a replication server when one of them is available; however, those changes are at risk because they are only available from the historical information. This mode may also introduce high replication latency. Indicates that all updates attempted on this are rejected when no replication server is available. ds-cfg-isolation-policy
