摘要： A system and method for implementing a common transaction manager interface. A system may implement an application server with a transaction manager module configured to provide a common application interface to a local transaction manager and a global transaction manager. The transaction manager module may be configured to determine if a transaction initiated by an application component should be managed by the local transaction manager or the global transaction manager. The local transaction manger may be configured to create a local transaction object for each transaction managed by the local transaction manager, and the global transaction manger may be configured to create a global transaction object for each transaction managed by the global transaction manager. The local transaction objects and the global transaction objects may provide a common application interface for implementing their respective transactions.

摘要： A transaction manager may be paused so that the transactions it manages are prevented from making transaction state changes. While the transaction manager is paused, the transactions that the transaction manager is executing may not be allowed to complete. A transaction manager may be configured to obtain permission from a transaction freeze manager in order to transition the state of a transaction. The transaction freeze manager may function as a read/write lock manager controlling locks on a transaction freeze object. In servicing a transaction state transition request, the transaction freeze manager may grant the transaction manager a read lock on the transaction freeze object. In servicing a transaction manager pause request, the transaction freeze manager may grant an administrative entity a write lock on the transaction freeze object.

摘要： Various embodiments of a networked computer system in which an application server associates an identity with each data source included in the system are disclosed. The networked computer system may include several backend systems, each including one or more data resources, and the identity of a data source may be unique to a data resource. When an application requests a connection to a data resource, the application server may ascertain the identity of the associated data source and compare this identity to identities of data sources with existing connections. If a match is found, the application server may provide an existing connection to the application, whereas if no match is found the application server may provide a new connection. The identity of a data source may include one or more data source configuration properties. In some embodiments, the identity may include database name, URL, and user name.

摘要： A transaction manager may be paused so that transactions managed by the transaction manager are prevented from making transactional state changes. When all transactions being coordinated by a transaction manager are paused, the transaction manager may be said to be paused or frozen. While the transaction manager is paused, the transactions that the transaction manager is supporting may not be allowed to complete. A transaction manager may obtain permission from a transaction freeze manager in order to transition the state of a transaction. The transaction freeze manager may function as a read/write lock manager controlling locks on a transaction freeze object. In servicing a transaction state transition request, the transaction freeze manager may grant the transaction manager a read lock on the transaction freeze object. In servicing a transaction manager pause request, the transaction freeze manager may grant an administrative entity a write lock on the transaction freeze object.

摘要： A system and method for excluding from a transaction accesses to one or more data sources marked as read-only. Data sources may be designated as read-only at a data source level, connection level, or on a registry. A global transaction may be delayed until two or more non-read-only data sources are being used. A transaction involving multiple data sources may still be managed as a non-global transaction if only one of the data sources is non-read-only. The other read-only data sources may be left out of the transaction.
摘要翻译：从事务中排除的系统和方法访问被标记为只读的一个或多个数据源。数据源可以在数据源级别，连接级别或注册表中指定为只读。全局事务可能会被延迟，直到使用两个或更多个非只读数据源。如果只有一个数据源是非只读的，则涉及多个数据源的事务仍然可以作为非全局事务进行管理。其他只读数据源可能不在事务中。

摘要： A distributed data system may include a plurality of nodes one or more of which may include at least one multi-threaded process operable to access portions of distributed data. A lock mechanism may grant locks to the multi-threaded processes for portions of the distributed data. Only a process holding a lock may access a portion corresponding to the lock. Threads of other processes may not access the portion. A process may include a lock management thread pool dedicated to managing locks for portions of the distributed data for access by other threads of the process. Each lock management thread of the lock management thread pool may request a lock for a portion of distributed data on behalf of the process. The process may hold one or more locks for portions of distributed data corresponding to one or more lock management threads of the lock management thread pool.
摘要翻译：分布式数据系统可以包括多个节点，其中的一个或多个可以包括可操作以访问分布式数据的部分的至少一个多线程进程。锁定机制可以向分布式数据的部分的多线程进程授予锁定。只有持有锁的进程可以访问与锁对应的部分。其他进程的线程可能无法访问该部分。过程可以包括锁管理线程池，专用于管理分布式数据的部分的锁以供进程的其他线程访问。锁管理线程池的每个锁管理线程可以代表进程请求一部分分布式数据的锁。对于与锁管理线程池的一个或多个锁管理线程对应的分布式数据的部分，该过程可以保存一个或多个锁。
