Abstract: A system and method for reducing communications overhead in a distributed transaction processing environment such as an XA environment. In accordance with an embodiment communication overhead is reduced in a transaction by deferring a transaction end communication. The deferred transaction end communication is determined from a subsequent XA transaction communication thereby reducing the number of networks calls required for each transaction and enhancing system performance.

Abstract: A system and method for reducing communications overhead in a distributed transaction processing environment such as an XA environment. In accordance with an embodiment communication overhead is reduced in a transaction start method by deferring a transaction start communication. The deferred transaction start communication is determined from a subsequent transaction processing communication thereby reducing the number of networks calls required for each transaction and enhancing system performance.

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.

The inflation device includes a syringe, a connector, and mechanical pressure indicator. The syringe includes a plunger slidably disposed within a barrel. The connector is configured to fluidly connect an outlet of the syringe with a surgical instrument balloon in establishing a closed inflation system between the syringe and an interior of the balloon. The pressure indicator is associated with the syringe and is configured to transition from a non-alert state to an alert state when a pressure of the inflation system has reached a predetermined level. In some embodiments, the inflation device is characterized by the absence of a pressure gauge.

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.

Abstract: A system and method can support transaction processing in a transactional environment. A transactional server operates to receive resource manager (RM) instance information from a data source that is associated with one or more RM instances, wherein the received instance information allows the transactional server to be aware of which RM instance that the transactional server is currently connected to. Furthermore, the transactional server operates to save the received instance information into one or more tables that are associated with the transactional server. Then, the transactional server can process a global transaction based on the instance information saved in the one or more tables.
