Hi, Currently Slice does not support failover. But it is on our road map. You can add new slices dynamically [1] or specify 'lenient' [2] to ignore slices that are configured but not currently reachable.
> good high availability framework that works best with OpenJPA? For MySQL, OpenJPA natively supports replication drivers [3] (meaning OpenJPA is aware of this driver and switches read-only modes when appropriate). Having said that, an HA database environment generally appears as an unified database at JDBC level. If that is the case, then OpenJPA is not even aware of the clustered, replicated database configuration as all it sees/operates on is a JDBC connection.
