I am trying really hard to set up a highly available Hyperic environment split across datacentres - below is a draft diagram of how I think I could make it work.
My main concern is the hyperic agents, being java processes, are not likely to register a change in IP address for the common name of hqserver.abcd.com without a restart .... right? Has anyone any experience in using GSS as an HA solution.
Some other notes:
- Due to infrastructure limitations, there is no "normal" load balancer we could use.
- This setup is assuming that the vmware implementation of postgresql has streaming replication!
- We have an awesome setup now with 4.x using oracle dataguard and a linux cluster, which vmware has chosen to destroy with its removal of oracle support >-(
