摘要： Multiple application server instances can be arranged in a cluster that implements a distributed EJB timer system. A high availability database can store EJB timer info. The EJB timer jobs can be distributed among the application server instances of the cluster that implement the distributed EJB timer system. In case of a failure of an application server instance, the EJB timer info can be used to reassign the EJB timer jobs associated with the failed application server instance.

摘要： A session replication system provides real-time data replication without unnecessarily slowing down the user experience. A system in accordance with the present invention may utilize a primary server to serve requests from a network client, as well as a secondary server to replicate the session information. When a request is received on the session, an attempt may be made to serve the request on the primary server. If the primary is unable to receive or respond to the request, the request may be served on the secondary server or on a new primary server. If the secondary server receives the request, the secondary server may become the new primary server. If a new primary server is selected, the new primary may request the session information from the secondary server.
摘要翻译：会话复制系统提供实时数据复制，而不必不必要地减慢用户体验。根据本发明的系统可以利用主服务器来服务来自网络客户端的请求，以及副服务器来复制会话信息。当会话接收到请求时，可能会尝试在主服务器上提供请求。如果主服务器无法接收或响应该请求，则该请求可能会在辅助服务器或新的主服务器上提供。如果辅助服务器接收到请求，则辅助服务器可能会成为新的主服务器。如果选择了新的主服务器，则新的主服务器可以从辅助服务器请求会话信息。

摘要： A method for managing objects in a clustered network includes a file system containing at least one copy of a data object. The method can involve several clustered servers in communication with the file system. A distributed consensus algorithm is used to select a host server. The selected host server can contain a copy of the data object, such as in local cache, providing access to the local copy to any other server in the cluster. Any change made to an item hosted by the host server can also be updated in the file system. If the host server becomes unable to host the object, a new host can be chosen using the distributed consensus algorithm. The other servers are then notified of the new host by multicast messaging.
摘要翻译：用于管理集群网络中的对象的方法包括包含数据对象的至少一个副本的文件系统。该方法可以涉及几个与文件系统通信的集群服务器。分布式共享算法用于选择主机服务器。选定的主机服务器可以包含数据对象的副本，例如本地缓存，可以将本地副本提供给集群中的任何其他服务器。对主机服务器托管的项目所做的任何更改也可以在文件系统中进行更新。如果主机服务器无法托管对象，则可以使用分布式共享算法选择新的主机。然后通过多播消息传送向其他服务器通知新主机。

摘要： A system for managing a message store in a network includes an object acting as a message store. In one embodiment, the message store is for Java Message Service. A lead server is selected from several servers. The lead server uses a distributed consensus algorithm to select a host server. The selected host server hosts the message store, providing sole access to the message store. The other servers are notified of the new host by messaging. In one embodiment, servers can send messages to the message store on the host and pick up any messages from the message store.

摘要： A timer master can assign scheduled jobs to other application servers of a cluster. Leases for the timer master can be started in a lease table. The timer master can store job info for the scheduled jobs in a database. In case of a crash of the application server, another application server of the cluster can be assigned the time master and use the job information to assign scheduled jobs.
摘要翻译：计时器主机可以将调度作业分配给群集的其他应用程序服务器。定时器主机的租约可以在租约表中启动。计时器主机可以将数据库中的计划作业的作业信息存储起来。如果应用程序服务器崩溃，则可以为群集的另一个应用程序服务器分配时间主站，并使用作业信息分配计划作业。

摘要： A Node Manager monitors the status of multiple servers. The Node Manager detects server failures, periodically monitors server health status, and performs server maintenance. When the Node Manager detects a server failure, it determines whether or not the server should be restarted. While periodically monitoring servers, the Node Manager may determine how often to trigger a health check, how long to wait for a response, and how to proceed if the server is deemed failed. The Node Manager may be controlled by an Administrative Server directly or by an external administrative agent. An administrative agent may control the Node Manager by interfacing with the Administrative Server. The Node Manager and AS may authenticate each other and encode their communications to each other for increased security.
摘要翻译：节点管理器监视多台服务器的状态。节点管理器检测服务器故障，定期监视服务器运行状况，并执行服务器维护。当节点管理器检测到服务器故障时，它确定是否应重新启动服务器。在定期监视服务器的同时，节点管理器可以确定触发健康检查的频率，等待响应的时间以及如果服务器被认为失败，如何继续。节点管理器可以由管理服务器直接或外部管理代理来控制。管理代理可以通过与管理服务器连接来控制节点管理器。节点管理器和AS可以彼此认证并将它们的通信彼此编码以增加安全性。
