Fault-tolerance and fault-containment models for zoning clustered application silos into continuous availability and high availability zones in clustered systems during recovery and maintenance

InactiveUS20070006015A1No impact on transaction processingSmall sizeError detection/correctionTransmissionFault toleranceIslanding
A cluster recovery and maintenance system, method and computer program product for use in a server cluster having plural nodes implementing a server tier in a client-server computing architecture. A first group of N active nodes each run a software stack comprising a cluster management tier and a cluster application tier that actively provides services on behalf of one or more client applications running in a client application tier on the clients. A second group of M spare nodes each run a software stack comprising a cluster management tier and a cluster application tier that does not actively provide services on behalf of client applications. First and second zones in the cluster are determined in response to an active node membership change involving one or more active nodes departing from or being added to the first group as a result of an active node failing or becoming unreachable or as a result of a maintenance operation involving an active node. The first zone is a fault tolerant zone comprising all active nodes that remain operational. The second zone is a fault containment zone comprising all active nodes participating in the membership change and at least a corresponding number of spare nodes to the extent that the membership change involves a node departure. During recovery and maintenance, fast recovery/maintenance and high application availability are implemented in the fault containment zone, while continuous application availability is maintained in the fault tolerant zone.

Remote health monitoring and maintenance system

InactiveUS20060004611A1Flexible and dynamic queryingLow communication chargeFinanceDrug and medicationsPhysiological monitoringPatient data
A system and method is described that enables a health care provider to monitor and manage a health condition of a patient. The system includes a health care provider apparatus operated by a health care provider and a remotely programmable patient apparatus that is operated by a patient. The health care provider develops a script program using the health care provider apparatus and then sends the script program to a remotely programmable patient apparatus through a communication network such as the World Wide Web. The script program is a computer-executable patient protocol that provides information to the patient about the patient's health condition and that interactively monitors the patient health condition by asking the patient questions and by receiving answers to those questions. The answers to these health related questions are then forwarded as patient data from the remotely programmable patient apparatus to the health care provider apparatus through the communication network. The patient data may also include information supplied by a physiological monitoring device such as a blood glucose monitor that is connected to the remotely programmable patient apparatus. When the patient data arrives at the health care provider apparatus, the patient data is processed for further management of the patient's health condition by the health care provider, such as forwarding another script program to the remotely programmable patient apparatus.

Restructuring view maintenance system and method

A database maintenance system and method are particularly suitable for maintaining a consistency of data between two or more database tables having schemas that may be heterogeneous (e.g., restructuring views of each other). Typically, one table is a base table and a second table is a restructuring view of the base table and may have been generated for faster query response, research, or the like. The restructuring view may have occurred naturally, or the base table may have been converted to the restructuring view using a series to of operators and optionally, a middleware schema. The restructuring view maintenance system is preferably configured to monitor changes to the base table, including changes to data and to metadata. The maintenance system is configured to receive notification of a modification to a base table, investigate the modifications, and determine which operator(s) have been used to convert the base table to the restructuring view. For each modification to the base table, the system then determines, according to the type of modification and the type of transformation used, which of a selected group of actions to take to map the modification onto the restructuring view. The selected group of actions may include variously: insert, update, delete, rename relation, drop table, and rename column, according to the type of modification and the mapping of the relationship between the base table and the target table.
