    Abstract: 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.

    Abstract translation: 在联网计算机系统中，定义分割代理，每个代理包括连接信息的缓存，其允许快速地将远程调用路由到对象，而不会在每次远程调用该对象时确定该对象的路由信息​​的开销。 在多个计算机系统中创建对象的多个副本。 然后创建指向对象的每个副本的分区代理。 分区代理允许快速访问这些对象副本，而不会同步其状态数据的开销。 缓存分区代理中的连接信息允许计算机系统调用远程对象，而不会因为每次调用确定用于访问远程对象的连接信息而导致性能损失。

    Abstract: A method, computer program product and system for maintaining data integrity of multiple copies of a piece of data in data servers of multiple data centers, includes maintaining a cluster of catalog servers, where one of the catalog servers is selected as the master catalog server, storing the piece of data in a primary data server chosen from the data servers, duplicating the piece of data to one or more backup data servers chosen from the data servers, recording a data state information to the master catalog server, duplicating the data state information to the cluster of catalog servers, and updating the data servers and the cluster of catalog servers when the primary data server fails.

    Abstract: In a networked computer system, partitioned proxies (714,716,718) are define d that each include a cache of connection information that allows for quickly routing a remote invocation to an object (722,732,742) 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 (720,730,740). A partitioned proxy is then created that points to each copy of the object. The partitioned proxies allow quickl y 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.

    Abstract: 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.
