When a directory server starts, or when a replication server that is connected to the directory server stops, the directory server must choose an adequate replication server for publishing and receiving changes. Two parameters affect which replication server is selected.
The geographic identifier of the replication server, or group ID
The server state of the replication server
A directory server selects a replication server according to the following criteria, in this order:
A replication server with the same group ID, that has received all the changes from that directory server, and that has the greatest number of available updates not yet replayed on that directory server.
A replication server with the same group ID and that has the greatest number of available updates not yet replayed on that directory server.
A replication server that has received all the changes from that directory server, and that has the greatest number of available updates not yet replayed on that directory server.
A replication server that has the greatest number of available updates not yet replayed on that directory server.
