Abstract: A method, system, and computer program product that includes a processor assigning a network connection to an application, based upon the application requesting the network connection from a pool of network connections for connecting applications to a network resource, the assigned network connection for communicating a message with the network resource. The processor replaces the assigned network connection in the pool with a placeholder comprising configuration data of the assigned connection. The processor determined a period of inactivity of the assigned network connection, and the processor returns the assigned network connection to the pool, based upon the period reaching a defined threshold of inactivity.

Abstract: Embodiments of the present invention disclose a method, computer program product, and system for class splitting in object-oriented environments in which objects are created by classes. Data is analyzed, in response to generating an instance of an original class in a code component. Fields are separated into sets based on the code paths that access the fields. A split class is generated for a set of fields which shares a common interface with the original class. Cells are replaced in the code component to the original class with a split class.

Abstract: Providing feedback on a musical performance performed with a musical instrument. An instrument profile associated with the musical instrument used to perform the musical performance is identified. The instrument profile comprises information relating to one or more tuning characteristics of the instrument. The pitch of notes of the musical performance are analyzed based on the instrument profile to determine a measure of tuning of the musical performance. A feedback signal is generated based on the determined measure of tuning.

Abstract: A method and computer program product is disclosed for managing a message broker and subscriber application programs in a publish/subscribe messaging system so as to maintain the state of the subscriber application program on the broker subscriber application program.

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.

Abstract: An apparatus for validating a value of a variable data item in a software routine in execution includes a profile set generator that generates a profile set of typical values of the variable data item, a profile rule generator that generates a profile rule representing the profile set, and a profile checker that determines if a value of the variable data item satisfies the profile rule.

Abstract: A method and computer program product is disclosed for managing a message broker and subscriber application programs in a publish/subscribe messaging system so as to maintain the state of the subscriber application program on the broker subscriber application program.

Abstract: Disclosed is a method comprising steps of: a broker software application receiving a first published message on a topic from a publisher application and storing the first published message in a local storage location along with an indicator which indicates that the first published message originated from a publisher application that is local to the broker software application; the broker software application receiving a second published message on the topic from another broker software application and storing the second published message in the local storage location in place of the previously stored first published message, along with an indicator which indicates that the second published message originated from a publisher application that is remote to the broker software application; and the broker software application delivering the second published message, from the local storage location, to a requesting subscriber application which has requested a last retained publication message on the topic.

Abstract: When a new broker is connected to a network, a loop detection message is sent over the new connection created by the new broker. The loop detection message includes topics. At each receiving broker, topics that cannot be propagated to a neighbor broker are removed. If the loop detect message contains no topics, the loop detect message is not propagated further. If the loop detection message returns to the new broker, a loop is detected.
