    Abstract: A computer is disclosed having a semiconductor memory; a disk data storage device of the type which automatically switches to a low power consumption mode when disk access is not required; and means for associating an application program with a plurality of data files which are usable by the application. The computer is arranged to load the plurality of data files from the disk data storage device into the semiconductor memory before use of the application and to save at least any modified ones of the plurality of files back to the disk data storage device after use of the application. In this way, access to the disk data storage device is not required during use of the application program, thereby reducing power consumption of the device.

    Abstract: An expert based system for managing error events in a local area network (LAN) includes an inference engine and a knowledge base storing data defining a plurality of causal relationships. Each of the causal relationships associates an error message with a cause, at least one implied relationship, and at least one trigger relationship. The inference engine accesses said knowledge base in response to a receiver error message to identify the error message and retrieve from the knowledge base its possible causes. The received error message is compared with other already received error messages to filter out repeated error messages. Already received error messages are examined to determine whether a triggering error message has arrived and, if so, the received error is discarded. The received error message is compared with existing diagnostic problems, termed a cluster, to determine if the received error message shares common causes with all error messages in the cluster and, if so, the received error message is added to the cluster. The causes in a cluster are evaluated to determine whether one cause in a cluster implies another cause and, if so, the implied cause is discarded. A user interface connected to the inference engine is used for reporting problems including correlated error messages, a cause and a recommended action for fixing the cause.

    Abstract: A limited multi-fault system and method manages error recovery in a local area network system. The system includes a data structure which store related error events, diagnostic problems and causes. In addition, a method of managing error events in real time and identifying causes and recommending actions is provided. A knowledge base is used to determine the causes and recommended actions for the problem.

    Abstract: A data storage disk device for a RAID disk array is disclosed, comprising a rotatably mounted disk having a data storage surface; a first head for reading data from and writing data to the data storage surface; characterised by a second head for reading data from the data storage surface; and control means for executing a write operation to a sector, said write operation including reading the contents of the sector via the second head for subsequent processing and writing new data to the sector via the first head, the first and second heads being arranged with respect to the data storage surface so that the new data can be written to the sector on the same revolution of the disk as the reading operation. The addition of a second head to the disk storage device improves the performance of the disk device for RAID applications.

    Abstract: A backup method for a computer database system in which updates to the mirrored data of a remote database are delayed for a delay time greater than or equal to the communication delay between the local and remote databases and updates to a remote log for the database are executed after corresponding updates to a local log without such a delay. In this way a consistent copy of the database may be recovered from the mirrored copy of the database and the remote log after destruction of the database system.
