摘要： A test link protocol which continuously monitors each link in a network to ensure that the link is correctly transmitting data. Each switch, or torus has at least one of two functional components: Send Test and Receive Test. The Send Test component monitors control codes at a torus link output. The Receive Test component monitors control codes at a torus link input. After a predetermined interval, the Send Test component makes a request to send a test.sub.-- link control code. The torus sends the test.sub.-- link code to the neighboring torus, where it is removed from the data stream and sent to that torus' Receive Test. The Receive Test then generates a response message and makes a request to send that message back to the originating torus. After receiving the message, the Send Test analyzes the message to determine whether the network link is working correctly. An error is also declared if the Send Test does not receive a reply within a predetermined interval.

摘要： A method, system and computer program product for compressing state changes to a datum in a primary data storage system. One embodiment of the invention involves receiving a first state-change entry describing at least a first transformation of the datum and an first value of the datum and receiving a second state-change entry describing at least a second transformation of the datum an a second value of the datum. The first and second state-change entries are reduced to a compressed state-change entry including a compressed transformation and a compressed value that are functionally equivalent applying the first transformation and first value, then applying the second transformation and second value, to the datum. The techniques of the invention may be utilized, for example, in redo and undo database replication operations.

摘要： One embodiment of the present method and apparatus for synchronization of client transactions executed by an autonomous client enables a client operating on a limited connection to a server to log transactions executed against a locally stored server database state. Logged transactions are then synchronized with a current server database state by delivering the transaction log to the server, which re-executes each logged client transaction against the current server database state, thereby reducing synchronization-related transaction conflicts.

摘要： A server allocation controller provides an improved distributed data processing system for facilitating dynamic allocation of computing resources. The server allocation controller supports transaction and parallel services across multiple data centers enabling dynamic allocation of computing resources based on the current workload and service level agreements. The server allocation controller provides a method for dynamic re-partitioning of the workload to handle workload surges. Computing resources are dynamically assigned among transaction and parallel application classes, based on the current and predicted workload. Based on a service level agreement, the server allocation controller monitors and predicts the load on the system. If the current or predicted load cannot be handled with the current system configuration the server allocation controller determines additional resources needed to handle the current or predicted workload. The server cluster is reconfigured to meet the service level agreement.

摘要： A multi-nodal data processing system includes a plurality of processing nodes, each node connected to plural other nodes by bidirectional data links. Each node comprises receivers for receiving messages on bidirectional data links and transmitters for transmitting messages on bidirectional data links. Each node records child nodes to which a message was transmitted and is further adapted to transmit a lock-up message received from a child node to a parent node, the lock-up message indicating a successful establishment of a message signal path to a destination node. Each node further is adapted to transmit a link cancel signal to another node to close the link in the event of an unsuccessful message transfer attempt over the link. Each node inhibits transmission of a lock-up signal to a parent node until link cancel signals have been received from all child nodes (other than a node from which a lock-up signal was received). A source node (where a message originates) continues transmission of its message, even before a lock-up signal has been received. The destination node which originates the lock-up message terminates a bidirectional data link by an end-of-session signal when it has received an entire message.

摘要： An on-demand manager provides an improved distributed data processing system for facilitating dynamic allocation of computing resources among multiple domains based on a current workload and service level agreements. Based on a service level agreement, the on-demand manager monitors and predicts the load on the system. If the current or predicted load cannot be handled with the current system configuration, the on-demand manager determines additional resources needed to handle the workload. If the service level agreement violations cannot be handled by reconfiguring resources at a domain, the on-demand manager sends a resource request to other domains. These other domains analyze their own commitments and may accept the resource request, reject the request, or counter-propose with an offer of resources and a corresponding service level agreement. Once the requesting domain has acquired resources, workload load balancers are reconfigured to allocate some of the workload from the requesting site to the acquired remote resources.
