Abstract: A method, system and computer program product for correlating business events in a complex business system. A flow diagram containing a collection of nodes (representing processes) and links (representing the transport connections) between these nodes is generated. An instance of an event stream from a node that is to be connected to an instance of an event stream from a neighboring node is identified when a node transports a transaction across a link. The metadata associated with the utilized link that was used to transport the transaction between the nodes is obtained. The instances of the event streams are then correlated using the obtained metadata. Further, each instance of the event streams is assigned an identification. In this manner, business events are correlated without the requirement of users providing a common key as well as without the requirement of monitoring each user of the system throughout the entire transaction.

Abstract: A method is presented in which federated domains interact within a federated environment. Domains within a federation can initiate federated single-sign-on operations for a user at other federated domains. A point-of-contact server within a domain relies upon a trust proxy within the domain to manage trust relationships between the domain and the federation. Trust proxies interpret assertions from other federated domains as necessary. Trust proxies may have a trust relationship with one or more trust brokers, and a trust proxy may rely upon a trust broker for assistance in interpreting assertions.

Abstract: A method and system for monitoring performance of a processing system, the processing system including a plurality of performance monitor counters (PMCs) and at least one monitor mode control register (MMCR) to configure the operations of at least one of the PMCs, includes identifying misaligned data items, and determining a performance penalty of misaligned data accesses during a predetermined sampling period.
