OpenAM 10.1 Session Failover Mechanism Part II

I talked more about the new Session Failover mechanism in OpenAM 10.1 in my previous blog. The use of  Open Message Queue and Berkeley DB Java Edition has been dropped in favor of the embedded OpenDJ that ships with each OpenAM release.

So how does it work with the embedded OpenDJ?

A new ou is created - ou=tokens. Whenever a user logs in and a session is created, an entry will be created in the OpenDJ under ou=famrecords,ou=openam-session,ou=tokens,dc=xxx,dc=xx.

And if you have multi instances of OpenAM, the multi-master replication (MMR) in the embedded OpenDJ kicks in to take care of session replication from nodes to nodes.

As simple as that. Neat!
