  • Mechanism for secure participation in a transaction by a third party
    Patent number: 7873832
    Abstract: Mechanisms for securely allowing a participant computing entity to engage in a transaction initiated by an initiator computing entity and managed by a coordinator computing entity. The initiator provides a transaction initiation request to the coordinator. Upon receipt, the coordinator accessing a transaction coordination context that includes information such as a secure key that may be used by a participant to register in the transaction. The coordinator then provides the coordination context to the initiator, which provides the coordination context to the participant(s) that are also to engage in the transaction. Each participant then generates a registration request that is based on the coordination context, and that is secured using the secure key provided in the coordination context.

  • ROUTING OF POOLED MESSAGES VIA AN INTERMEDIARY
    Publication number: 20100318654
    Abstract: Message intermediation for multiple service instances, while allowing the service instance to control whether messages are processed under a transaction. The message intermediator chooses to dispatch messages among different backend service instances based on any routing rules. The message intermediator performs a peek-lock of message from a forward-end queue, and assigns the message to a service instance. The message is provided into a backward-end queue specific to the assigned service instance. The service instance may then process the message, perhaps under a transaction created at the service instance. Upon completion of processing, the message is deleted in the back-end queue, which causes the forward-end queue to delete the message under the same transaction created by the service instance. Whether or not this deletion at the forward-end is committed or rolled back depends on whether the transaction created at the service instance is committed or rolled back.

  • TRANSACTION PROCESSING IN TRANSACTIONAL MEMORY
    Publication number: 20100100689
    Abstract: A transactional memory processing system provides for the integration of transactional memory concepts at the compiler-level into a higher-level traditional transaction processing system. Atomic blocks at the compiler-level can be specified as atomic block transactions and include the features of atomicity and isolation. Actions within this atomic block transaction include the enlistment of resource managers from a repository. The repository can now include a pre-programmed memory resource manager to manage the transactional memory. As in traditional transactions, a commit protocol can be used to determine if the actions are valid and can be exposed outside of the transaction. Unlike traditional transactions, however, the transaction is not necessarily doomed if all of the actions are not validated. Rather, memory conflicts can cause a rollback and re-execution of the atomic block transaction, which can be repeated as long as necessary, until the memory resource manger votes to commit.
