Abstract: A method and system for replicating database data is provided. One or more standby database replicas can be used for servicing read-only queries, and the amount of storage required is scalable in the size of the primary database storage. One technique is described for combining physical database replication to multiple physical databases residing within a common storage system that performs de-duplication.

Notification messages provide consistency between each diskless system's in-memory cache and the state of the shared database files.

Abstract: A system and method are provided for enabling a portable media player to obtain media content from secondary systems, such as other portable media players, via local wireless communication. In general, the portable media player stores proxy information identifying the media content of a number of media files in the user's media collection rather than the media files themselves. When a secondary system is within a local wireless coverage area of the portable media player, the proxy information for the media files, or a subset thereof, is provided to the secondary system. In response, the secondary system identifies media files stored by the secondary system having media content matching the media content identified by the proxy information. The secondary system then provides a notification of the identified media files to the portable media player, which may then obtain the identified media files from the secondary system.

Abstract: A content file purge mechanism for a content delivery network (CDN) is described. A Web-enabled portal is used by CDN customers to enter purge requests securely. A purge request identifies one or more content files to be purged. The purge request is pushed over a secure link from the portal to a purge server, which validates purge requests from multiple CDN customers and batches the requests into an aggregate purge request. The aggregate purge request is pushed from the purge server to a set of staging servers. Periodically, CDN content servers poll the staging servers to determine whether an aggregate purge request exists. If so, the CDN content servers obtain the aggregate purge request and process the request to remove the identified content files from their local storage.

Abstract: Systems and methods for synchronizing multiple copies of data in a network environment that includes servers and clients so that incremental changes made to one copy of the data can be identified, transferred, and incorporated into all other copies of the data. The synchronization can be accomplished regardless of whether modifications to the data have been made by a client while the client is in an on-line or off-line mode of operation. The clients cache data locally as data are modified and downloaded. The caching enables the clients to access the data and allows the synchronization to be performed without transmitting a particular version more than once between a client and a server. Such elimination of redundant data transmission results in an efficient use of time and network bandwidth.

Thus, a change in the property pane is immediately reflected in the view component, and a change in the view component is immediately reflected in the property pane.

Two or more synchronization tasks required to be performed for an item can, if not inherently serial in nature, be performed in parallel, optimizing synchronization of the item.

Moreover, multiple threads for one or more synchronization tasks can be concurrently executed when supportable by the current operating system resources. Rules can be established to ensure synchronization activity is not degraded by the overextension of system resources.
