Hi all,
i have a request from a customer about 2 replication architectures and i would like to know if it's possible to implement them: 1 - Master Server -> "hub" Server -> Slave Server
Expand on what you mean by "hub"?
Hub comes from Sun Directory Server terminology which means a read-only server that receives/get updates to/from a master and send updates to a slave
Ah, a proxy. In our case that would be pushed based Syncrepl (slapd-ldap(8) and Syncrepl in refreshAndPersist mode).
2 - Server1 <-> Server2 <-> Server 3
This looks like Multi-Master?
Yes, except that Server1 isn't directly synchronized with Server3
An other question: Is the replication with slurpd or SyncREPL supported over WAN ?
Yes, but please try to use Syncrepl over slurpd
Are there some restrictions ?
Firewall/routing etc. Depends what you have setup/require.
Of course, these points must be configured correctly but, i supposed typically latency issues due to the distance or connection closed by a firewall due to inactivity.
Gavin.
Rgds, Bruno.
