摘要： In a shared data system comprising one or more primary nodes and a plurality of secondary nodes, global lock manager on a primary node manages locks for shared resources by exchanging an abstract lock state with local lock managers on the secondary nodes. The abstract lock state includes a particular representation of all of the applications on the nodes that are requesting or are granted locks. The exchange of these particular lock states instead of individual requests improves performance by increasing concurrency and reducing off-machine communication. A global deadlock detector on a node detects and resolves global deadlocks, in conjunction with local deadlock detectors on the secondary nodes.

摘要： A mechanism for automatic reallocation of shared external storage structures is provided. The shared external storage divides the dynamically allocable storage into fixed sized blocks referred to as allocation units. To create an object of a specific type, the shared external storage uses some number of allocation units. If the object will fit in one allocation unit, then it is placed in one allocation unit. If the object is larger than one allocation unit, then the appropriate number of allocation units is obtained and chained together to contain all of the information of the required object. When an object so allocated is no longer needed, the shared external storage breaks the object down to a set of one or more fixed sized allocation units. The shared external storage then returns the allocation units to the pool of available objects.

摘要： A mechanism is provided for multi-part aggregated variables in structured external storage. The shared external storage provides a serialized, aggregated structure update capability. The shared external storage identifies each local value for which a group value is needed by name. Each time a member writes out its value, the member specifies the name of the object, the member's current value, and the type of aggregate function to apply (e.g., minimum, maximum, etc.). The structured external storage in one atomic operation updates the member's value, recalculates the aggregate of all of the individual values, and returns the aggregate to the member. The advantage of this approach is that it requires only one write operation to the structured external storage. The update operation does not require locking, because the operation is atomic.

摘要： A method and apparatus for optimizing a data structure of an external data storage facility shared by a plurality of data processing systems, the data structure being allocated by a first allocation command which includes first allocation parameters based on an amount of storage space in the external data storage facility assigned for creation of the data structure and a composition of the data structure, includes a device for determining values of the first allocation parameters, to thereby determine a first composition of the data structure, a device for determining an actual usage of the data structure, to thereby determine a second composition of the data structure, a device for comparing the first composition of the data structure with the second composition of the data structure, and a device for issuing, based on an output from the comparing device, a second allocation command having second allocation parameters, to the data structure for reallocation thereof. The issuing device includes a device for adjusting the first composition of the data structure to the second composition, as storage space in the external data storage facility and processing cycles become available to execute the second allocation parameters. Until the second allocation parameters are achieved, the reallocation of the data structure remains pending and all processing commands are accepted and processed by the external data storage facility.

摘要： A method of communicating between two business entities, each of the business entities utilizing a different communication protocol, wherein a business conversation is established between the entities, comprises the steps of: providing a business-to-business (B2B) protocol exchange for facilitating communications between the business entities, the B2B protocol exchange being operatively connected to the business entities. The method further includes the step of receiving, at the B2B protocol exchange, a message from one of the business entities in a first communication protocol, translating the received message in the first communication protocol into a translated message in a second protocol used by another of the business entities and sending the translated message to the other business entity. In this manner, the present invention provides a framework for facilitating communication between two business entities implemented using different communication protocols.
