Release Date: Monday, November 01, 2010
This version introduces the data replication element of the resilience features package. The second element, journaling, will follow in the near future.
QM's replication package allows cascade replication where data can be replicated onward through a chain of servers and symmetrical replication that can be used to replicate in both directions between two systems subject to some rules to handle concurrency control. We are hoping to publish an article describing practical use of symmetrical cascade replication in the near future.
This release also contains many other new features requested by our users. See the openqm.com web site for full details.
