Abstract: A client computer batch message transaction group is defined that corresponds to a set of client computers. A set of separate messages is received from at least some of the client computers in the client computer batch message transaction group. For each given separate message of the set of separate messages, a write is performed to a single message reception queue, and a determination is made regarding whether the given separate message was successfully written to the single message reception queue. Responsive to a determination that all messages of the set of separate messages were successfully written to the single message reception queue, all of the messages of the set of separate messages are written to disk as a single disk write.

Abstract: In response to receipt of a request message from a requester, a reply message is created. The reply message includes a message identifier of the request message copied from the received request message. The reply message is published to each of a group of replicated message queues. The reply message is identifiable by the requester using the copied message identifier of the request message on any one of the group of replicated message queues prior to being consumed by the requester.

Abstract: A client computer batch message transaction group is created that includes a set of client computers from which messages are committed as a batch messaging transaction to a single message reception queue. In response to receiving separate messages from at least two of the set of client computers within the client computer batch message transaction group, the separate messages are grouped under the batch messaging transaction as a single unit of work to commit to the single message reception queue. A single batch transaction commit decision is computed based upon whether a write of each of the separate messages grouped within the single unit of work to the single message reception queue is successful.

Abstract: In response to receipt of a request message from a requester, a reply message is created. The reply message includes a message identifier of the request message copied from the received request message. The reply message is published to each of a group of replicated message queues. The reply message is identifiable by the requester using the copied message identifier of the request message on any one of the group of replicated message queues prior to being consumed by the requester.

Abstract: A client computer group is created at a server computer by selecting a subset of a group of client computers, where each of the group of client computers has a separate communication channel with the server computer. A message from at least one of the subset of the group of client computers is received at the server computer. In response to receiving messages from at least two of the subset of the group of client computers within the client computer group, the messages are grouped under a single unit of work. A single decision associated with the single unit of work for the client computer group is computed. Each of the at least two of the subset of the group of client computers is operable to accept the single decision.

Abstract: A publish/subscribe messaging network in which a distributed set of publish/subscribe brokers comprises a first subset of publish/subscribe brokers, each arranged to store proxy subscription information for the whole of the distributed set of brokers; and a second subset of publish/subscribe brokers, each configured to send subscription information for local subscribers to one or more brokers within the first subset of publish/subscribe brokers, and configured to request, from a broker within the first subset of brokers, proxy subscription information following receipt of a message.
