Prasad, 1. In write-behind mode database updates are not transactional. If you want Ignite to maintain underlying Oracle transaction to make sure cache and DB are always consistent, you need to use synchronous write-through. As for compute, you can execute transaction within compute, but you can't do compute inside a transaction like in your example above. Basically, the whole transaction must be executed in a single thread, while compute can be executed even on another node.
2. Load cache process is not triggered automatically, you need to start it manually. Just call IgniteCache#loadCache method and Ignite will make sure data is loaded on all nodes. -Val -- Sent from: http://apache-ignite-users.70518.x6.nabble.com/
