CLM db2 replication

There's another good article here on DB2 HADR best practices: http://public.dhe.ibm.com/software/dw/dm/db2/bestpractices/DB2BP_HADR_0911.pdf
It's possible to set up HADR over a WAN, to your standby in Europe, for example, but you would need to tune it for ASYNC replication so that the WAN latency did not affect the primary performance. This setup would only be performant if you also had a standby Jazz server located in Europe, and failed over to that at the same time. Having the Atlantic between your Jazz app server and database server is not a performant topology.
