Abstract: A system for workflow placement in a computer system wherein the performance of a system processing a workflow is monitored against one or more performance measures. One or more logic elements from the workflow are delegated for subsequent processing to other systems in the computer system in response to one or more of the one or more performance measures being within a predetermined range.

Abstract: A method for event processing within a complex event processing environment. The method includes monitoring a plurality of event processing paths of the complex event processing environment. The method includes determining that utilization of server resources in the complex event processing environment has exceeded a threshold value and identifying one or more event processing paths responsible for the high utilization of server resources. The method includes determining that the one or more event processing paths contain an independent rule, wherein an independent rule includes a rule or a rule subset where data for processing of the rule or rule subset is accessible by a client computing device. The method then includes determining the client computing device can perform processing of the independent rule and transferring processing of the independent rule to the client computing device.

Abstract: A computer accesses a stack data and a source code of a program. The computer searches for a first change made to the program, wherein the first change is one of a change to a method of the program, a change to a class of the program, a change to a method that is invoked by the program, or a change to a class containing a method that is invoked by the program. The computer identifies the first change that was made to the program and determines the probability that the identified first change caused one or both of an error and a regression. The computer generates a ranked list of identified changes based, at least in part, on the probability that the identified first change caused one or both of an error and a regression.

Abstract: A computer captures a thread state data of a first program. The computer generates a second program by applying a first program patch to the first program. The computer inserts additional code into a source code of the second program. The computer executes a first performance test using the second program and the inserted additional code. The computer monitors a first status of the second program and the inserted additional code that are under the first performance test. The computer determines a degree that a first deadlock state was prevented during the first performance test. The computer generates a first message based, at least in part, on the determined degree that the first deadlock state was prevented during the first performance test.

Abstract: Embodiments of the present invention provide a method, system and computer program product for dynamic, granular messaging persistence in a messaging system. In an embodiment of the invention, a method for dynamic, granular messaging persistence in a messaging system is provided. The method includes monitoring operational performance of a message broker and receiving a message for queuing in a message queue of the message broker. The method also includes parsing the message to extract different fields and corresponding priorities and selectively storing in fixed storage, data for corresponding ones of the different fields based upon consideration of corresponding ones of the priorities and the monitored operational performance. Finally, the method includes queuing the message in the message queue.

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: A method and system are provided for providing event-processing rules in an event-processing environment. The method includes providing at least one generalised event-processing rule to a customer, receiving customer input of rule customization to produce a customized rule, and storing the customized rule in Polish notation for processing using stack-based processing. The method also includes receiving notification of an event for a customer, retrieving a customized rule relating to the customer, and processing the customized rule using stack-based processing.

Abstract: A method and system for message handling wherein a structured message is transmitted as a reduced message with the structure removed. The method includes: monitoring messages to be transmitted, the step of monitoring comprising: for each message, identifying one or more elements within the message and identifying the format of content and/or structure encapsulated by those elements; determining the probability that a message will conform to a previously identified format; and using the determined probability to decide when to transmit a format template for the message, wherein the format template is for use by a destination to add the structure removed by a message source back into the message.

Abstract: A communication system includes a server and a client that transmits messages to the server. The messages include data and descriptive tags and may be in XML format. The server initiates a negotiation with the client relating to message format switching. If the client indicates that the client can accept message format switching, the server instructs the client to switch further messages to a simpler message format including solely data.

Abstract: A method, system and apparatus for performing selective data processing based upon a static analysis of the code of a compiled object. A compiled object, for example an enterprise bean, can be analyzed to determine how individual methods in the enterprise bean access specific objects. Those specific objects can include, for instance, data members of a class, or class objects passed into one or more individual methods of the enterprise bean. Where the individual methods of the enterprise bean do not mutate or otherwise change the state of the specific objects, those objects can be accessed by reference only. Importantly, where the specific objects are data fields linked to a table in a database as managed by a container managed persistence (CMP) bean, an update to the table will not be required when the static analysis of the enterprise bean otherwise indicates that the data fields are merely accessed, but not updated.
