Abstract: Systems and methods consistent with the invention may include executing a business task by receiving an instruction to execute a business task; generating an event-condition-action (ECA) rule during execution of the business task; generating a graphical representation corresponding to the ECA rule; and executing, using a processor of the computer system, the business task based on an evaluation of the graphical representation.

Abstract: Systems and methods consistent with the invention may include initiating an execution of the business process, the business process being represented by a workflow model that includes a synchronization point, retrieving, from a memory device of the computer system, a pre-computed parameter corresponding to the workflow model, and executing, using a processor of the computer system, the business process by using the pre-computed parameter, wherein the pre-computed parameter represents a configuration of the workflow model in which the synchronization point is activated.

Abstract: The subject matter disclosed herein provides methods and apparatus, including computer program products for handing transactions. The method may include, for example, processing, at a state correlation engine, a plurality of transactions; saving the effects of at least one of the transactions to a persistence, when the at least one transaction includes a reliable interaction with an external application; saving other transactions to a buffer rather than to the persistence; and reading the at least one transaction from the persistence and continuously executing rules representing the other transactions in response to a failure causing a recovery. Related systems, apparatus, methods, and/or articles are also described.

Abstract: Methods and apparatus, including computer program products, are provided for transporting processes within a distributed computing system, such as a cluster. In one aspect, the computer-implemented method may receive an event at a first node. The event may correspond to a process instance for handling the received event. The process instance may be transported from a second node to the first node. The process instance may be transported from a persistence when the process instance is inactive and, when the process instance is active, the process instance may be persisted to enable transport to the first node. Related apparatus, systems, methods, and articles are also described.

Abstract: The subject matter disclosed herein provides methods and apparatus, including computer program products, for state alignment and transaction coupling to enable reliable communication between an application, such as a backend system, and a correlation engine (or rules engine). In one aspect there is provided a method. The method may provide a first interface to receive information from an adapter for an application separate from a state correlation engine and provide a second interface to receive information from the state correlation engine to the adapter. The first and second interfaces may provide state alignment between the application and the state correlation engine. Related systems, apparatus, methods, and/or articles are also described.

Abstract: The subject matter disclosed herein provides methods and apparatus, including computer program products for rules-based processing. In one aspect there is provided a method. The method may include, for example, evaluating rules to determine whether to enable or disable one or more actions in a ready set of actions. Moreover, the method may include scheduling the ready set of actions, each of which is scheduled for execution and executed, the execution of each of the ready set of actions using a separate, concurrent thread, the concurrency of the actions controlled using a control mechanism. Related systems, apparatus, methods, and/or articles are also described.
