Oracle Directory Server Enterprise Edition 184.108.40.206 doesn't support any O.S. layer cluster, since it's High Availability model is achieved at application layer through the Multi-Master Replication.
Please refer to the official product documentation available here:
Thanks for your update ..
I am going to use ODSEE 220.127.116.11 as LDAP context to configure the WebSphere MQ JMS. So can we achieve High Availability using Multi-Master Replication(MMS) for IBM MQ.
As you mention above that "High Availability model is achieved at application layer through the Multi-Master Replication". Please explain me how to achieve high availability in application layer.
I already sent the link to the Oracle official product documentation where the Multi-Master Replication is explained, and how to configure a Multi-Master Replication Topology.
However, the 'concept' of the multi-master is that in such environment all the Directory Servers with role 'MASTER' can accept updates, and these changes are 'replicated' across the topology over the LDAP protocol.
In that way you achieve the high availability having at the same time, multiple machines that *CONTAINS* and *ARE AUTHORITATIVE* to upgrade the same set of data.
