摘要:
The subject invention pertains to systems and methods of data item synchronization. More specifically, the invention concerns synchronization of data entities utilizing an intermediary or shared storage system and associated data store. Each client sync device can include or be associated with an interface that facilitates communication between client synchronization devices and the intermediary storage system. The interface can send change information to the shared store utilizing change data packets including a data change attribute, a prerequisite knowledge attribute and a learned knowledge attribute. The data change attribute can specify changes to be made to certain data, while the attribute can include a complete copy or reference to a complete copy or single instance of data.
摘要:
The invention is directed to systems and methods for the synchronization of two clients both utilizing a common storage platform (e.g., the new storage platform of the related inventions) to synchronize through an intermediary that is not using the same common storage platform (e.g., instead using a legacy storage platform that does not itself support synchronization for the new storage platform). Data is synchronized using the existing capabilities of the intermediary but where the data structure of the clients is preserved. An “adapter” is used to enable a client to interact with an intermediary by compensating for the intermediaries inability to preserve the data structure elements inherent to the client's storage platform. Specific embodiments are directed to either or both upload-syncing data from a client to a intermediary and/or download-syncing data from an intermediary to a client. Certain additional embodiments are further directed to compaction of data on the intermediary.

A system for parallel asynchronous command execution is provided. The system includes a first computer system for directing a plurality of calls to at least one other computer system. The first computer system invokes a remote procedure in the other computer system and receives results from the procedure via an event triggered by the other computer system. The system may also include a distributed object architecture for communicating between the first computer system and the other computer system.

A system and method for monitoring events of a plurality of members configured as an entity. Configurable event logging settings can be defined at a first member and dynamically propagated to each member of the entity to establish event logging configuration settings at each of the plurality of members. In one aspect of the invention, a system and method log different event types in accordance with configuration settings into a common event type data format at a plurality of members. The different event types can then be coalesced for the entire entity and returned to a requestor residing at a single location. Additionally, a unique identifier can be assigned to assist in monitoring of events. Also, to assist in monitoring, data that is common to all event types can be stored in a separate table from data specific to an event type.

An information server adapted to service requests for information has an integral database containing configuration information, application information, and/or content information. The information in the database is stored in a hierarchical fashion with elements that correspond, in some degree, with physical storage structure or individual information objects on the information server. Path names received in information requests are broken into constituent components and are used to retrieve configuration information, application information, and/or content information from the database and information objects from physical storage. In the database properties stored at one hierarchical level may be inherited by lower hierarchical levels. The database is preferably provided with a programmatic interface that allows concurrent access to and administration of the database. Mechanisms to notify registered users of changes or events that occur with respect to the database are implemented.

In one example, data may be divided into blocks, and the blocks may be stored in various storage resources. Data to be stored may be provided to a data divider. The data divider may divide the data into blocks. Redundancy may be introduced into the blocks to allow the original data to be reconstructed at some point in the future, even if fewer than all of the original blocks are available. The blocks may be sent to a data shuffler, which may shuffle the blocks, and may provide a key that describes how to reconstruct the original data from the blocks. The key may be provided to the owner of the data. When the original data is to be retrieved, the key may be provided to a reassembler, which retrieves the blocks from the various storage resources and reconstructs the data using the key.

A system and method is provided for gathering and aggregating operational metrics (e.g., performance metrics, process events, health monitor state, server state) for a plurality of members as a single entity and for a plurality of entities as a singular entity. The system and method provides for operational metrics of members and entities to be aggregated and retrieved as a single result set, such that entity wide operational metrics can be acquired, monitored and displayed as a single entity.

The electrical inductive apparatus including non-magnetic flux shields constructed of strips of highly electrically conductive material which are arranged to form a continuous loop around the core window. The shields are disposed parallel to the laminations of the magnetic core and adjacent the top and bottom surfaces of the core. Current induced in the shields by the leakage flux from the windings produces an opposing flux which prevents substantially all of the winding leakage flux from entering the magnetic core.
