    摘要: A method of operating a messaging system comprising receiving a message, creating a list element for the message, the list element comprising expiry data and a reference to the message, appending the list element to an expiry list, periodically deleting list elements from the expiry list that correspond to consumed messages and transferring list elements that correspond to unconsumed messages from the expiry list to a time sorted expiry index, and traversing the expiry index deleting those messages that have expired.

    摘要: Provided are methods, data processing systems, recovery components and computer programs for recovering from storage failures affecting data repositories. At least a part of the recovery processing is performed while the data repositories are able to receive new data and to allow retrieval of such new data. Although new data items may be received into the repository and retrieved therefrom during recovery processing, updates to the data repository which were performed before the failure and which are then restored to the repository by the recovery processing are restored within a recovery unit of work and are inaccessible to processes other than the recovery process until successful completion of the recovery unit of work. The recovery processing ensures that the recovered repository is consistent with the state of the repository at the time of the failure, but is available for addition and retrieval of new data items before completion of the recovery processing.

    摘要: To enable adaptive monitoring of the resource, metrics about the workload received at the resource from one or more clients are used to derive monitoring feedback comprising a recommendation as to how the monitoring should be performed. This is then used as input to a decision making process controlling the monitoring of the resource. The recommendation may be for the monitor to increase or decrease its monitoring interval. The resource may decide to increase or decrease its monitoring depth or checking, or may suggest a new monitoring depth to the monitor.

    摘要: A data item is retrieved from a data store in a data processing system. The data processing system comprises an index, which at least partially indexes the data store, and also a partiality definition store. The partiality definition store indicates a part of the data store which is referenced by the partial index. A request is received for a data item from the data store and responsive to determining that the requested data item is not referenced by the partial index, the data store is searched by using the partiality definition store to avoid searching a part of the data store which is known to be indexed.

    摘要: A device for installing and removing a removable computer component, such as a data storage drive or computer card, into or out of a computer housing. The device features a drive sled to which the data storage drive is mounted. A stationary carrier tray is secured to the computer housing. Interlocking angled tracks on the drive sled and the carrier tray secure the two structures together. To promote easy coupling of the drive's electrical interface connectors, the front end of the drive sled has a floating guide plate with forward-projecting locating pins, which pins are used to align the electrical connectors held by the floating guide plate. A rack and pinion mechanism is provided. The rack is disposed on the top of the carrier tray while the pinion is located on the underside of the drive sled. As the drive sled slides onto the carrier tray, the lever-actuated pinion gear engages the rack and consequently displaces the drive sled relative to the stationary carrier tray. A torsion spring may be used to bias the pinion. The carrier tray also features a raised wedge that latches the lever at one extreme position when the drive sled is in its forward-most position to lock the data storage drive inside the computer housing.

    摘要: Responsive to a client application initiating a synchronous communication with a server application by sending a request via an asynchronous communication manager, one or more checks are performed to identify a cause of any failure to provide a response to the client application satisfying synchronous communication criteria. The results of one or more checks are used to determine whether to back out any data updates performed by/on behalf of the server application in response to the request.

    摘要: A data processing system for message handling comprises a coupling facility for receiving messages, the coupling facility arranged to maintain a queue of messages, and a database for storing messages. A component, such as a server, of the system is arranged to detect that a message is of a size above a predetermined threshold, and therefore stores this larger message in the database and enters a proxy in the queue of messages.
