摘要： A container managed persistent (CMP) enterprise java bean (EJB) framework includes support for accessing multiple data sources within one deployment. A CMP EJB includes a number of different attributes that can be a variety of values. A session EJB that acts as a front-end to the CMP EJP includes a resource reference for each of the different data sources that the entity CMP EJB may utilize. The application server environment includes a map that defines mapping information between the attributes of the CMP EJB and the resource references of the session EJB. Using the mapping information during runtime, the application server connects to the appropriate data source.

摘要： A method, apparatus, system, and signal-bearing medium that, in an embodiment, send a broadcast message to a cluster of servers receive a point-to-point message from a coordinating server of the cluster, where the coordinating server joined the cluster before all other servers in the cluster. The point-to-point message includes routing data regarding all of the servers in the cluster. In an embodiment, the broadcast message includes a record that includes an identification of a new server, resource data regarding the new server, and a time that the new server joins the cluster, and the servers in the cluster add the record to the routing data and send a request to the new server via the record. In another embodiment, the broadcast message includes records for all servers in a second cluster, and the new server sends the routing data to the servers in the second cluster. If a server leaves the cluster, its record is removed. In this way, a cluster can respond to servers dynamically joining and leaving the cluster while reducing network traffic.

摘要： A method, apparatus, system, and signal-bearing medium that, in an embodiment, receive a change request from a first client at a first time, where the change request includes a key that identifies a field in a data object. A determination is made that the first client changed the field identified by the key at a second time that is before the first time and that a second client changed the field identified at a third time that is after the second time and before the first time, and the key is sent to the second client. The client receives the key, and in various embodiments invalidates the key in a cache or removes the key from the cache. In an embodiment, the data value of the change request is also sent to the second client, which updates the cache with the data value. In this way, stale data in a cache at a client is either updated or removed.
摘要翻译：一种方法，装置，系统和信号承载介质，其在一个实施例中在第一时间从第一客户端接收改变请求，其中所述改变请求包括标识数据对象中的字段的密钥。确定第一客户端在第一时间之前的第二时间改变由密钥标识的字段，并且第二客户端改变在第二时间之后且在第一次之前的第三时间标识的字段，并将密钥发送给第二个客户端。客户端接收密钥，并且在各种实施例中使高速缓存中的密钥无效或从高速缓存中移除密钥。在一个实施例中，改变请求的数据值也被发送到第二客户端，第二客户端用数据值来更新高速缓存。以这种方式，客户端缓存中的陈旧数据将被更新或删除。

摘要： One computer system in a cluster includes a dynamic routing mechanism that receives all incoming messages for the cluster. When a message is received, the dynamic routing mechanism checks its dynamic routing table, and routes a message to the appropriate partition that corresponds to the address of the message. If a resource has been moved to a different partition, the dynamic routing mechanism may route the message to the old partition instead of the new one. In this case, the old partition receives the message, determines whether the message is intended for it, and if not, the partition forwards the message to the appropriate target partition. The partition then notifies the dynamic routing mechanism of the change in location of the resource, which causes the dynamic routing mechanism to update its dynamic routing table to reflect the change in location for the resource.
摘要翻译：集群中的一个计算机系统包括动态路由机制，其接收集群的所有传入消息。当接收到消息时，动态路由机制将检查其动态路由表，并将消息路由到与消息地址对应的适当分区。如果资源已被移动到不同的分区，则动态路由机制可以将消息路由到旧分区，而不是新的分区。在这种情况下，旧分区接收消息，确定消息是否针对该消息，如果不是，分区将该消息转发到适当的目标分区。分区然后通知动态路由机制资源位置的变化，这导致动态路由机制更新其动态路由表，以反映资源位置的变化。
