摘要： A system and method for server load balancing that includes server affinity. The system can be incorporated into application servers to support load balancing algorithms for RMI objects that provide server affinity. Server affinity uses smart load balancing for external client connections in such a way that it uses preexisting connection and reduces overhead: the client considers its existing connections to the application server instances when choosing the server instance on which to access a service. If a service is configured for server affinity, the client-side stub attempts to choose a server instance to which it is already connected, and continues to use the same server instance for method calls. All stubs on that client will attempt to use that server instance. If the server instance becomes unavailable, the stubs fail over, if possible, to a server instance to which the client is already connected.

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 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： A system and method can support using a data source to connect an application server with a clustered database. The clustered database includes a plurality of database instances and is associated with a notification service. The notification service can be used by the clustered database to broadcast notifications that describe a state change in the plurality of database instances. The data source includes a connection pool, which manages a set of connections to the plurality of database instances in the clustered database. The data source operates to register with the notification service to receive notifications on the change of the clustered database, wherein the application server operates to configure and manage connection to the clustered database, adaptively according to the state change of the clustered database at run time.

摘要： A system and method for application server with self-tuned threading model. A server queue is used as a priority scheme, including a number of entries therein associated with received requests, and which allows the entries to have expressed priorities or share values, instead of simply the number of threads. Flexibility is retained to express the threads in raw numbers whenever this might be desired, or to express constraints on the number of threads to be made available.
