    • 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.

    • 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 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.
    • 事务管理器可能被暂停,使得由事务管理器管理的事务被阻止进行事务状态改变。 当交易管理器协调的所有交易都被暂停时,交易管理器可能被称为暂停或冻结。 当事务管理器暂停时,事务管理器支持的事务可能不被允许完成。 可以将事务管理器配置为从事务冻结管理器获得许可以便转换事务的状态。 事务冻结管理器可以用作控制事务冻结对象上的锁的读/写锁管理器。 在处理事务状态转换请求时,事务处理管理器可以授予事务管理器对事务冻结对象的读锁定。 在为事务管理器暂停请求提供服务时,事务冻结管理器可以向管理实体授予对事务冻结对象的写锁定。

    • 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.

    • A method for inducing multi-threading in software code may use blocks of code as the basis for scheduling and to suggest concurrent execution for each block. The method may comprise marking one or more blocks of code in an application coded for sequential execution to generate marked code. The marking may comprise inserting a marker at each of the one or more blocks to suggest that block for potential concurrent execution. Concurrent code may be generated from the marked code. Generating the concurrent code may comprise analyzing the marked code to estimate performance benefits of concurrently executing the marked blocks of code and determine which marked blocks would meet a performance benefit threshold if executed concurrently. Generating the concurrent code may also comprise transforming one or more of the marked blocks into corresponding concurrently executable tasks. The method may include scheduling one or more of the concurrently executable tasks.
