    Abstract: A system and method can support processing a transaction with a plurality of transaction branches. A transaction manager operates to send, to a resource manager, a prepare request for each said transaction branch in the plurality of transaction branches with the exception of at least one transaction branch. Furthermore, after receiving an indication from the resource manager that the received preparation requests are handled successfully (i.e. the transaction branch is read-only and has been committed), the transaction manager operates to send a commit request to commit said at least one transaction branch, which is on hold, to the resource manager.

    Abstract translation: 系统和方法可以支持用多个事务分支处理事务。 事务管理器操作以向资源管理器发送除了至少一个事务分支之外的多个事务分支中的每个所述事务分支的准备请求。 此外，在从资源管理器接收到所接收到的准备请求被成功处理的指示之后（即，事务分支是只读的并已被提交），事务管理器操作以发送提交请求来提交所述至少一个事务分支 ，这是暂时的，给资源经理。

    Abstract: A system and method can support transaction processing in a transactional environment. A coordinator for a global transaction operates to propagate a common transaction identifier and information for a resource manager instance to one or more participants of the global transaction in the transactional environment. The coordinator allows said one or more participants, which share resource manager instance with the coordinator, to use the common transaction identifier, and can process the global transaction for said one or more participants that share the resource manager instance using one transaction branch.

    Abstract: A system and method can provide high throughput transactions in a transactional system. A system and method can, via a transaction manager, obtain information on a plurality of resource managers. The transaction manager can further manage a plurality of transaction branches, where each of the plurality of transaction branches can be associated with a different one of the plurality of resource managers. The methods and systems can associate a transaction identifier with each of the plurality of transaction branches, which can result in a plurality of transaction identifiers, where each of the plurality of transaction identifiers can include a branch identifier for each of the plurality of transaction branches. The methods and systems can perform one or more transactional operations on the plurality of transaction branches based on the different transaction identifiers.

    Abstract: Techniques are provided for reducing coordinator roundtrips during a distributed transaction while still ensuring that the transaction coordinator has all the information the coordinator needs to finalize the distributed transaction. The techniques involve inserting “finalization information” from the participants of a transaction in the return messages sent by the participants of the transaction. The finalization information that is included in the return messages sent by each participant is information that enables a coordinator to confirm/cancel or commit/rollback the changes made by the participant, and any participants that are downstream from the participant. When the participants are done, the finalization information obtained from the return messages is provided to the coordinator to allow the coordinator to finalize the distributed transaction.

    Abstract: A system and method can handle various database state notifications in a transactional middleware machine environment. The system can connect one or more transaction servers to a database service, wherein the database service is associated with a notification service. Furthermore, a notification service client that is associated with said one or more transaction servers can receive one or more events from the notification service, wherein said one or more events indicates one or more state changes in the database service. Then, one or more transaction servers operate to adaptively respond to the one or more state changes in the database service.
