Thanks for the very detailed and prompt response there Ben. The DB2 side will be handled by the team of DBA's working with me (I work for an insurance company - we have lots of DB2) so I'll pass this on to them. The Sametime 9 system is already in and functioning - I just want to add HADR for DB2 as all other components are HA.
What I was after are the changes and settings on the WAS / Sametime (ST) side for Sametime 9 as both WAS and ST have changed considerably since 2010 when your blog post was written. For instance re fail-over to the HA DB2 server you state "If the primary DB2 server should fail WebSphere will not be able to read/write to it even if the standby has been promoted to the primary. To fix this Automatic Client Reroute can be used within WebSphere."
Following along I can see those options still exist in WAS 8.5.5 - is there anything new you are aware of in 8.5.5 that I would need to do to accomplish the fail-over?
