    摘要： A system and method for optimizing a storage system to support short data object lifetimes and highly utilized storage space are provided. With the system and method, data objects are clustered based on when they are anticipated to be deleted. When an application stores data, the application provides an indicator of the expected lifetime of the data, which may be a retention value, a relative priority of the data object, or the like. Data objects having similar expected lifetimes are clustered together in common data structures so that clusters of objects may be deleted efficiently in a single operation. Expected lifetimes may be changed by applications automatically. The system automatically determines how to handle these changes in expected lifetime using one or more of copying the data object, reclassifying the container in which the data object is held, and ignoring the change in expected lifetime for a time to investigate further changes in expected lifetime of other data objects.

    摘要： A computerized method, system and computer program product for managing an object store is disclosed. An exemplary method includes the the steps of: collecting performance statistics about storage repositories from which an object(s) can be retrieved; retrieving an object from a storage repository, in response to an object reference; determining a reference probability (RFP) for the object; determining and associating a replacement penalty (RPP) with the object wherein the RPP is based on the one or more performance statistics and the RFP; and storing the object and an associated RPP for the object. The storage repositories could be locally attached devices, network sites, and/or remotely attached devices. If there is insufficient space in the object store for a new object, an object(s) can be replaced with the new object based on the associated RPP of the cached objects. Alternatively, the resolution of one or more objects in the object store can be reduced until sufficient space is available. The RPP determination is preferably based on the RFP for the object and performance and/or usage statistics. Examples of the performance statistics include: availability; size; latency; and bandwidth. An example of the usage statistics includes statistics on time delays (D) associated with abort requests made via the Internet, for example, using a browser. The RPP could include an annoyance function for a specific requester or set of requesters by instrumenting the browser STOP function and analyzing time interval statistics associated with its usage.

    摘要： A system and method wherein a mobile user, or a user interacting with a mobile program, can at any time initiate a program status request. The program status request initiates the sequence of events whereby the current location of the program is determined and/or the current user location is made available to the program without the necessity of either entity changing location. Further, the agent script for the program maintains a composite data structure which includes an input buffer for storing input variables, an output buffer for storing output values to be displayed to the user, a program state data structure, and an optional bag buffer for temporarily storing input variables which the program will need in the course of future execution. By maintaining such a composite data structure, it is assured that all necessary information can be provided at a program location regardless of whether the program or the user has relocated.
