Rewrite for EAP6, failure recovery is automatic starting in EAP 5.1.1. The failure recovery subsystem of ArjunaCore will ensure that results of a transaction are applied consistently to all resources affected by the transaction, even if any of the application processes or the machine hosting them crash or lose network connectivity. In the case of machine (system) crash or network failure, the recovery will not take place until the system or network are restored, but the original application does not need to be restarted. Recovery responsibility is delegated to Section 5.1, “The Recovery Manager�. Recovery after failure requires that information about the transaction and the resources involved survives the failure and is accessible afterward: this information is held in the ActionStore, which is part of the ObjectStore. Warning If the ObjectStore is destroyed or modified, recovery may not be possible. Until the recovery procedures are complete, resources affected by a transaction that was in progress at the time of the failure may be inaccessible. For database resources, this may be reported as tables or rows held by “in-doubt transactions�. For TransactionalObjects for Java resources, an attempt to activate the Transactional Object (as when trying to get a lock) will fail.
