摘要： Disclosed is a method, apparatus, computer program and computer program product for adjusting the frequency at which data is backed up. This involves receiving a target recovery time. A current estimated recovery time is then determined and the current and target times are compared. If it is determined that the current estimated recovery time has reached a predetermined threshold relative to the received target recovery time a new backup should be initiated.

摘要： A method for aiding resolution of a transaction for use with a transactional processing system comprising a transaction coordinator and a plurality of grouped and inter-connected resource managers, the method comprising the steps of: in response to a communications failure between the transaction coordinator and a first resource manager causing a transaction to have an in-doubt state, connecting, by the transaction coordinator, to a second resource manager; in response to the connecting step, sending by the transaction coordinator to the second resource manager, a resolve request comprising a resolution for the in-doubt transaction; in response to the resolve request, obtaining at the first resource manager, by the second resource manager, a lock to data associated with the in-doubt transaction; and in response to the obtaining step, determining, by the second resource manager, whether the transaction is associated with the first resource manager.
