Abstract: A messaging system and method are provided to enable transactional work, done as a result of a recipient processing an asynchronous message, to be involved in the transaction under which message was sent. Involvement may be directly in the senders transaction or indirectly through a separate transaction which can be a subordinate to, a child of, or merged with the transaction under which message was sent. The message is delivered by calling an operation, a definition of which has been registered for the queue. If the message is added to a queue for subsequent delivery to a recipient, details of the transaction under which message was sent are added to the message. As a result the recipient can take appropriate action to ensure that any transactional work, it causes to happen, will be done directly or indirectly under the scope of the transactions under which message was sent.

Abstract: An IPC protocol/network allows for dynamic dedication of ports in order to reduce system latencies and power consumption. The IPC system allows for either the IPC server or any of the IPC clients to request that a port(s) be dedicated for use in the transfer of data, such as real-time data. The request for a port can occur for example by a client transmitting a control message to the server/another client requesting that a particular port be dedicated for its use. The server and client(s) negotiate the port dedication and once dedicated, the client can use the dedicated port to transfer its data either to the server or to another client. In one embodiment, the server can take away a dedicated port if it determines it needs the port for another data transfer that may be more critical or have a higher priority.

Abstract: A user centric policy creation and enforcement system, method and apparatus. The method can include observing state changes and action invocations in disparate applications through visual views of the applications. Correlations can be established between the observed state changes and action invocations. Rules can be formulated in a policy based upon user selected ones of the established correlations. Each of the rules can specify a state change in at least one of the applications. Each of the rules further can specify at least one resulting action invocation in at least one other of the applications. Finally, the policy can be applied so as to automatically respond to each subsequently observed state change with a specified action invocation.
