摘要： A method and system for processing a transaction request in a distributed data handling architecture. Responsive to receiving a transaction request at a master transaction server, a transaction identifier that identifies a data operation specified by the received transaction request is recorded within a local memory of a replica server. Data operation results are committed master transaction server memory and responsive to committing the data within the master transaction server memory, a post commit signal is sent to the replica server. Data operation results are also committed within local memory of the replica server, and responsive to a failover condition that prevents the master transaction server from sending the post commit signal, the recorded transaction identifier is utilized to synchronize data stored locally within the replica server with data stored within a persistent backend data store shared by the master transaction server and the replica server.

摘要： In an embodiment, a request is received that includes data and a specification of a store operation, a key, and a local database. A predicted format for the data is determined based on a type of the requester and whether the local database is a primary database or a replica database. If the predicted format is a relational format, the data is converted to the relational format, if not already in the relational format, and stored into the local database. If a most-frequently predicted historical format is the relational format, the data is converted to the relational format, if not already in the relational format, and stored into the local database. If both the predicted format and the most-frequently predicted historical format are an object format, the data is converted into the object format, if not already in the object format, and stored into the local database.

摘要： A method, system and computer program product for dynamically modifying target server specifications to improve the success rate of client requests in a data network. A client's initial request is transmitted by a client router to a dynamically updating target server, based on information in a client's routing table. A Dynamic Server Specifications (DSS) utility automatically revises one or more target specifications of a client's request that is not initially fulfilled. The DSS utility then initiates the transmission of the modified request to an alternate server. If the request to the alternate server is also not fulfilled, the DSS utility may further modify the request to target an arbitrary server in order to download a current routing table. When the client receives a current routing table, the initial request is revised based on the current routing information, with full constraints re-established, and forwarded to the relevant target server.

摘要： An apparatus and method is described for improving access to mostly read data on network servers. The preferred embodiments more efficiently utilize replicated data servers to minimize server response time for improved performance of data access to network servers by workload managing client requests across the primary server and all replicated servers when it is possible to do so. In preferred embodiments, a load balancer supplies the most current data for mostly read data transactions while maximizing server usage by workload managing client requests across the primary server and all replicated servers. Client requests are managed by a load balancer in the workload manager. Client requests are sent by the load balancer to replicated servers when a routing table (stale data marker list) indicates that the data is in a safe period. Clients are directed exclusively to the primary server only during data update times.

摘要： An apparatus, program product and method utilize on-demand propagation of routing information to reduce the overhead associated with distributing routing information throughout a distributed computing system. The staleness of the routing information utilized in routing client requests for a particular client is gauged based upon the number and/or frequency of client requests issued for that client that require rerouting, e.g., as indicated in responses returned in response to the client requests. Once the reroutes of client requests meet a desired propagation criterion, updated routing information is then requested for the client.

摘要： A method and system for providing secure access to a patient's medical records. In one embodiment, an access authorization account is received that specifies access parameters relating to the patient's medical records. The access authorization account specifies: an authorized user identification that specifies one or more user identification codes that may be utilized to access the patient's medical records; content scope authorization that specifies the scope of data content within the patient's medical records that is accessible using the authorized user identification; content access authorization that specifies the extent to which the accessible data content is modifiable using the authorized user identification; and an access period that specifies an access termination time. The access authorization account is processed by an access manager to determine and implement limited access to the patient's medical records.

摘要： In a networked computer system, partitioned proxies are defined that each include a cache of connection information that allows for quickly routing a remote invocation to an object without suffering the overhead of determining routing information for the object each time the object is remotely invoked. Multiple copies of an object are created in multiple computer systems. A partitioned proxy is then created that points to each copy of the object. The partitioned proxies allow quickly accessing these object copies without the overhead of synchronizing their state data. Caching connection information within the partitioned proxies allows a computer system to invoke a remote object without the performance penalty of determining with each invocation the connection information for accessing the remote object.
