We are looking to deploy DB2 HADR with Sametime 9. There are guides to doing the DB2 piece but I can't find anything on the setup / configuration requirements for Sametime in WAS to utilise this. There is an old blog post from 2010 here >> http://collaborationben.com/2010/12/19/db2-hadr-clustered-meeting-servers/ but as much has changed since then I'm not sure it's relevant.
Also, DB2 has to manually failed over but it's fairly short on detail on how to do that.
If anyone has experience with this can you please share or if there are links to a guide I'd be grateful.
