Abstract: A method and system are provided for capturing and applying changes to a data structure made by one or more processing nodes. The method includes providing a data structure including one or more elements (200-205), maintaining a linked record of changes (200a-200c, 201a-201c, 205a-205b) to each element (200-205) made by a processing node. A new value of an element (200-205) is linked to the previous value. A record (250) of the sequence of changes to the elements (200-205) is also maintained. In one embodiment, the linked record of changes (200a-200c, 201a-201c, 205a-205b) is a push down stack. The data structure is defined including indirections (210-215) pointing to most recent values of an element (200-205), which in turn points to the previous value of the element (200-205), forming a linked record to the initial value of the element.

Abstract: A method provides cross enterprise communication in which intermediary communication components carry out cross enterprise communication. The method at a first sending enterprise includes: receiving a signed encrypted message from a sender within a first enterprise; validating the sender; decrypting the message; encrypting the message for receipt by a second enterprise; signing the encrypted message by the first enterprise; and sending the re-signed re-encrypted message to a second enterprise. The method at the second receiving enterprise includes: receiving a signed encrypted message from a first enterprise; validating that the first enterprise is the sender; decrypting the message; encrypting the message for receipt by one or more recipients at the second enterprise; signing the encrypted message by the second enterprise indicating that the message is from the first enterprise; and sending the re-signed re-encrypted message to the one or more recipients of the second enterprise.

Abstract: A system enables intermediary communication components to carry out cross enterprise communication. At a first sending enterprise the system comprises: a processor executing code to: receive a signed encrypted message from a sender within a first enterprise; validate the sender; decrypt the message; encrypt the message for receipt by a second enterprise; sign the encrypted message by the first enterprise; and send the re-signed re-encrypted message to a second enterprise. At the second receiving enterprise, the system comprises a processor executing code to: receive a signed encrypted message from a first enterprise; validate that the first enterprise is the sender; decrypt the message; encrypt the message for receipt by recipients at the second enterprise; sign the encrypted message by the second enterprise indicating that the message is from the first enterprise; and send the re-signed re-encrypted message to the recipients of the second enterprise.

Abstract: Method for logging diagnostic information, for use in a transactional environment having function for sending a transactional and re-sendable request to an application program. A counter is associated with the request, wherein a value associated with the counter is updated when an error occurs in the environment. The environment also comprises a counter threshold. The method utilizes a comparator, responsive to sending the request, for comparing the value associated with the counter against the counter threshold; a tracing control component, responsive to the value associated with the counter meeting the counter threshold, for enabling a tracing program; and a logging component, responsive to re-sending the request, for logging diagnostic information generated by the tracing program.

Abstract: In a data processing system wherein a plurality of data processing applications are in communication with each other, a first data processing apparatus running a first data processing application, the apparatus, method and computer program product has: means for receiving a message from a second data processing apparatus running a second data processing application; means for determining whether a predetermined indication is provided in the received message; and means for reporting the receipt of the received message to a central logging trace facility for logging of the message when the predetermined indication is provided in the received message.
