Tom Jenkinson commented on JBTM-312:

Would this work as a general design pattern if you wanted to implement a HA recovery coordinator?

1. Use the JDBC object store.

2. Configure a recovery coordinaor (RC) on each node to recover all (*) nodes. You can only *start* one of these RC at any one time

3. Develop some "watchdog" process runs on every node and monitors the current RC process and if it fails, uses a group protocol to elects one of the other RC's to start

4. Rather than starting the RC on one of the nodes, start the watchdog processes and allow them to enable one of the RC's

Would this work for JTS?
