Installing Non-Recover FES enables you to use front-end servers that do not need to be recovered in the event of a failure. In this case, when the unit containing such a front-end server fails and is forcibly terminated, HiRDB automatically completes any uncommitted transactions, which means that the database is updated even if the unit containing the front-end server is not restarted. For details about recovery-unnecessary front-end servers, see 8.2 Recovery-unnecessary front-end servers.
