摘要:
A method for resolving a unit of work involving a plurality of participants, for use in a publish/subscribe system having a plurality of participants that subscribe to a first topic and at least one component having access to an outcome associated with the unit of work. The component publishes, to the first topic, a first message comprising a first outcome associated with the unit of work. If there is a failure associated with a first participant, a second participant use the published outcome to recover the unit of work.
摘要:
Responsive to a client application initiating a synchronous communication with a server application by sending a request via an asynchronous communication manager, one or more checks are performed to identify a cause of any failure to provide a response to the client application satisfying synchronous communication criteria. The results of one or more checks are used to determine whether to back out any data updates performed by/on behalf of the server application in response to the request.

Systems methods and computer programs are disclosed that enable generating transaction messages. In one embodiment, the method comprises: generating a transaction message using a first computing device, the transaction message comprising: compensation information comprising instructions indicating a transaction to be executed in order to undo a previously executed transaction; and a transaction identification that identifies an executing program within the first computing device to execute the transaction; and sending the transaction message over an input/output device connected to the first computing device for processing on a second computing device.
摘要:
A method for resolving a unit of work involving a plurality of participants, the method comprising the steps of: generating logic comprising an identifier generator; aggregating the logic with an owning application of a unit of work; and in response to the owning application initiating the unit of work, generating, by the identifier generator, an identifier associated with the unit of work.
摘要:
A system, method, apparatus, and computer program product uses a plurality of message transmitters to achieve high availability message transmission. The plurality of message transmitters are each operable to transmit a message to a subscriber. In accordance with a determination, for example, of the value of the connections, the message is copied and transmitted to the plurality of the message transmitters so that at least one of the plurality of message transmitters transmits the copy to the subscriber. The at least one message transmitter may be selected by analyzing the message and determining an associated rule based on characteristics of the message.
摘要:
A method for providing atomicity for a unit of work involving a plurality of participants, the method comprising the steps of: sending a prepare request to at least one participant, wherein the request comprises data required for recovery prurposes of the unit of work; and on recovery of the unit of work, recovering the unit of work comprising: obtaining the data from the at least one participant; and using the obtained data to recover and preserve the atomicity of the unit of work.
