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

摘要

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.
