Abstract: Disclosed is a method for selecting one of a plurality of versions of a software component of a message queuing software product to perform a task. One or more rules describing one or more characteristics of the plurality of versions of the software component is provided. Responsive to a determination that the rule applies to the task to be performed: a list of the plurality of versions of the message queuing software product is obtained, it is checked whether the software component of the one of the plurality of versions of the message queuing software product is available for use; and the most preferred version of the message queuing software component available is used to perform the task. Responsive to a determination that none of the rules apply to the task to be performed, the task is performed with the most preferred version of the message queuing software component.

Abstract: Embodiments relate to controlling persisting of data to disk for use with a messaging system including an application operable for generating and sending a message to a destination. An aspect is an apparatus, which includes a comparator operable to determine whether the message includes common data, and an extractor, responsive to a determination that the message includes common data, configured to extract the common data and non-common data from the message. The apparatus also includes a persistor operable to determine whether the common data have already been persisted to disk. The persistor is operable, in response to a determination that the common data have not already been persisted to disk, to separately persist the common data and the non-common data to disk. The persistor is operable, in response to a determination that the common data have already been persisted to disk, to persist the non-common data to disk.

Abstract: Processing events for use with a complex event processing system that includes a server computer system and a client application executable on a client computer system. The processing includes analysing content of the events and assigning a plurality of attributes to associated event processing logic. A first attribute is associated with event processing logic that is operable to be applied at the client computer system and a second attribute is associated with event processing logic that is operable to be applied at a server computer system. The processing also includes using, in response to receiving a first event, assigned attributes to determine whether event processing logic associated with the first event is operable to be applied at the client computer system. The first event is forwarded to the server computer system based on determining that the event processing logic associated with the first event is not operable to be applied at the client computer system.

Abstract: An exemplary embodiment of this disclosure is a method for operating a data processing system, where the data processing system includes a service bus connected between a client and a server. The service bus includes one or more applications configured to mediate message flow between the client and the server. The method includes receiving a message from the client at the service bus, and mediating the message at a message-mediating application of the service bus. The mediation includes adding a header to the message, the header defining a source and a predetermined condition under which a target can respond directly to the source. The source is either the client or an application of the service bus, and the target is either an application of the service bus or the server.

Abstract: Resource constraints for a group of individual application products to be configured for shared resource usage of at least one shared resource within a single operating system instance are analyzed by a resource allocation module. An individual resource allocation for each of the group of individual application products is determined based upon the analyzed resource constraints for the group of individual application products. The determined individual resource allocation for each of the group of individual application products is implemented within the single operating system instance using local inter-product message communication bindings by the single operating system instance.
