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: A system and method can support a distributed transaction lock in a transactional middleware machine environment. The system can use a global transaction identifier to locate a hash bucket in a transaction hash table, wherein the transaction hash table contains a plurality of hash buckets. Then, the system can lock said hash bucket in the transaction hash table, and allow only one process to access one or more global transaction entry structures in the transaction table before said hash bucket is unlocked, wherein said one or more global transaction entry structures are associated with the locked hash bucket in the transaction hash table.

Abstract: A system and method can support transaction processing in a transactional environment. A transactional system operates to route a request to a transactional server, wherein the transactional server is connected to a resource manager (RM) instance. Furthermore, the transactional system can assign an affinity context to the transactional server, wherein the affinity context indicates the RM instance that the transactional server is associated with, and the transactional system can route one or more subsequent requests that are related to the request to the transactional server based on the affinity context.

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 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.

Abstract: A system and method can support a transactional system in a heterogeneous computing environment. The transactional system can provide one or more buffers, wherein said one or more buffers operate to represent one or more data structures in a mainframe computing environment in the heterogeneous computing environment. Also, the transactional system can provide a transactional adaptor, which operates to convert one or more data elements between said one or more data structures in the mainframe computing environment and said one or more buffers in the transactional system.

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: A system and method can support application interoperation in a transactional middleware environment. A first transaction server operates to initiate a global transaction, wherein the first transaction server that is associated with a first format identifier (ID), and wherein the global transaction includes a plurality of branches and each said branch is associated with an individual branch qualifier. Furthermore, the first transaction server can direct at least one branch of the global transaction from the first transaction server to a second transactional server, wherein each said transactional server is associated with a second format identifier (ID), and configure a plurality of branches in the global transaction to share a common format identifier (ID).

Abstract: Systems and methods are provided for supporting transaction recovery based on inline delegation of transaction logs to a database. The system can retrieve transaction recovery information of a transaction from a persistence store, wherein the transaction recovery information is persisted on a resource manager that is associated with the persistence store during a prepare phase. Furthermore, the system can retrieve one or more in-doubt transactions from one or more participating resource managers of the transaction. Then, the system can determine whether to commit or roll back the one or more in-doubt transactions by matching the one or more in-doubt transactions to the transaction recovery information.

Abstract: A system and method can support a tightly-coupled global transaction. One or more transaction servers operate to span the global transaction with a plurality of branches across a plurality of transaction domains, wherein each said branch is associated with an individual branch qualifier, and each said transaction domain is associated with a different global transaction identifier (GTRID). Furthermore, the transaction servers can configure the plurality of branches in the global transaction to share a common global transaction identifier (ID), and associate a composite branch qualifier with at least one branch of the global transaction in a transaction domain, wherein the composite branch qualifier includes a global transaction identifier (GTRID) that is associated with the transaction domain and an individual branch qualifier that is associated with the at least one branch.
