In accordance with an embodiment, described herein is a system and method for improving performance of an executable process defined by a process execution language in a service-oriented architecture (SOA) middleware environment. Flow states and audit data of a process instance can be stored in a dehydration store implemented on a distributed in-memory data grid, and transferred to a persistent storage at a configurable interval, or at certain state changes such as completions and faults of the process instance. A user interface can be used to configure the persistence policy for the process instance, and to retrieve the flow states and audit data from the persistent storage for process monitoring and diagnosis. The flow states data in the persistent storage can also be used for resuming execution of the process instance after a planned system maintenance, or a system crash.

System and method for using an in-memory data grid to improve performance of a process defined by a process execution language in a SOA middleware environment

A system and method for facilitating execution of a portion of a process via a subprocess. An example method includes encapsulating process logic of a portion of a parent process via the subprocess, wherein the parent process is encoded via a business process language characterized by process lifecycle management functionality; using an instance of a call activity in a scope of the parent process or subprocess to activate the subprocess, yielding a called subprocess in response thereto; and employing a business process runtime engine to adjust a scope of the subprocess to inherit the scope of the process used to call the subprocess, thereby enabling the process lifecycle management functionality to govern a lifecycle of the subprocess. In a more specific embodiment, the business process language includes standard Business Prosecution Execution Language (BPEL); the parent process represents a business process; and the subprocess includes a standalone subprocess.

Execution semantics for sub-processes in BPEL

Embodiments of the present invention provide improved concurrency by reducing the time period (also referred to herein as a locking window or contention window) during which a record is locked. This provides the benefits of pessimistic locking schemes by preventing transaction due to concurrent updates, while also reducing the time during which a record is exclusively locked. This improves user experience and performance.

Techniques to reduce contention windows

A system and method for facilitating reuse of a portion of process logic by different processes. An example method includes providing a subprocess that is adapted to perform the process logic in a file accessible to a composite system, wherein the subprocess is adapted to be called by a first parent process via a subprocess extension to a business process language employed to encode the first parent process; using a call activity defined as part of the subprocess extension, and included in a scope of the first parent process to facilitate access to functionality of the subprocess by the parent process; and employing a business process engine to facilitate instantiating the subprocess, resulting in an instantiated subprocess in response thereto; and using a second parent process to share use of the instantiated subprocess with the first parent process.

Using sub-processes across business processes in different composites

A system and method for enabling reuse of a portion of a business process. An example method includes employing a business process language to facilitate accessing a definition of a subprocess characterizing the process logic, wherein the definition indicates one or more parameters to be used by the subprocess to implement a task specified by the process logic; and employing the definition to facilitate: using one or more variables of a parent process as one or more arguments that are passed to an instantiated version of the subprocess, and mapping the one or more arguments to the one or more parameters. In a more specific embodiment, the example method further includes characterizing a behavior of the subprocess via one or more dynamic scoping rules. The business process language includes a version of Business Process Execution Language (BPEL), and a BPEL extension activity facilitates defining the subprocess.

Subprocess definition and visualization in BPEL

A system and method for enhancing performance of a business process execution engine, utilizing a database, a cache, and a lock management system operating in cache. The lock management system, upon receiving a request for a stored business process instance, determines by accessing the cache whether stored business process instance is locked and if the lock is expired. The stored business process object is served to the business process execution engine if it is not locked or the lock is expired. The lock functionality is implemented by writing, rewriting, and/or erasing a companion lock object stored in the cache such that no database access is required to determine whether a stored business process instance is locked.
