摘要： One embodiment is directed to a method in a computer system including a host computer and at least one storage system including first and second storage volumes, the host computer including at least one application program executing thereon. The method comprises acts of intercepting and redirecting an access request from the at least one application program to the first storage volume to the second storage volume. Other embodiments are directed to a computer readable medium with instructions for performing the method, a host computer with at least one controller to intercept and redirect the access request. Other aspects are directed to methods in a computer system including a host computer, a first storage system including a first storage volume, and a second storage system including a second storage volume, wherein the second storage volume is a hardware mirror of the first storage volume. One method comprises an act of servicing a read request to the second storage volume while maintaining the second storage volume as an active hardware mirror of the first storage volume. Another method comprises an act of, in response to a failure preventing access from the host computer to the first storage volume, servicing access requests directed to the first storage volume from the second storage volume without reconfiguring the host computer.

摘要： A method and system for processing a request to retrieve data from a database is disclosed. The method of the present invention comprises receiving the request which comprises a function that processes at least one data item specified in the request, retrieving the at least one data item from a database, and invoking the function. When the function is invoked, at least one parameter comprising information related to the at least one data item is passed to the function. Thus, a function can be written independently of the data which they are called to process.

摘要： Methods and apparatus for migrating a logical object. In one embodiment, a migration is performed by automatically determining the source location(s) of the logical object, moving the data stored therein to a target location while maintaining the availability of the data at the source location to an application program, and automatically servicing access requests from the application program at the target location after moving the data. In another embodiment, a migration is performed by automatically provisioning target location(s) to store a logical object, moving the data in the logical object to the target location(s) while maintaining its availability to an application program, and automatically servicing access requests from the application program at the target location after moving the data. In a further embodiment, a migration is performed by moving the data within a logical object from a source logical volume to a target logical volume, automatically servicing access requests from an application program at the target logical volume after moving the data, and retiring the source logical volume.

摘要： A method and apparatus for managing a migration of a data set from at least one first storage location to at least one second storage location, wherein read requests to the data set from at least one application program executing on a computer system initially are serviced from the at least one first storage location. The data set is copied from the at least one first storage location to the at least one second storage location, and then at least one aspect of the computer system is modified so that read requests to the data set are serviced from the at least one second storage location to achieve the migration. In one embodiment, the migration is subsequently undone by modifying the at least one aspect of the computer system so that read requests to the data set are again serviced from the at least one first storage location. In another embodiment, after the migration is performed, a determination is made as to whether to finalize the migration.

摘要： Described are methods, apparatus and computer programs for managing persistence within a data processing system such as a messaging system, database system or file system. The method for managing persistence includes a deferred evaluation (230,330,430) of at least one criterion associated with costs and/or benefits of saving to persistent storage, instead of persistence behavior being fully predefined. The evaluation may be performed when a disk write is about to be performed (240,340,440), or at various times during processing of a data update and at various points within a data processing network. In a messaging solution, the method for managing persistence includes a dynamic evaluation (230,330,430) of costs and/or benefits of saving to persistent storage, with the evaluation being performed at various points in the messaging network after the message has been created and sent by the originating entity. The method includes determining whether message data and/or log records relating to the message require saving to persistent storage, in accordance with the costs and/or the benefits of saving to persistent storage. The benefits of persisting may be determined with reference to a message value (400).

摘要： A method is used in controlling access to XAM metadata. An object derived from a set of content is stored in an object addressable data storage system. The object has an object identifier. Storage system specific metadata is added to the object. The storage system specific metadata is accessible when the object is retrieved using the object identifier. Based on sub-object access control, a retrieving application is allowed to have access to only a subset of the object.

摘要： An application services platform includes a platform chassis, a network interface supported by the platform chassis, and a control circuit supported by the platform chassis and coupled to the network interface. The control circuit is arranged to connect to a network through the network interface, and receive an application service command from a user. The application service command gives the control circuit permission to provide an application service to an application running on a server on the network. The control circuit is further arranged to provide the application service to the application running on the server on the network in response to receipt of the application service command. The application services platform is capable of being provided in the form of an appliance-style device which is simply added as a new device on the network.
