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： 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.
