The performance of BPEL processes depends on the composing web services. Monitoring web service performance and adapting to changes in service performance are essential for creating self-tuning BPEL processes. Unfortunately, BPEL supports neither performance monitoring nor dynamic adaptation mechanisms.

BPEL Remote Objects: Integrating BPEL Processes into Object-Oriented Applications
2010 IEEE International Conference on Services Computing, 2010Service-orientation and object-oriented design are common practice in the field of business application development. Business process execution languages help to facilitate the orchestration of Web services in service-oriented architectures (SOA). However, using business processes from within object-oriented and event-driven applications is difficult ...

A BPEL Observability Enhancement Method
2010 IEEE International Conference on Web Services, 2010WS-BPEL processes are usually overlapped in large Business applications composed of several Web Services. Such applications are more and more developed with respect of quality processes. Testability is an important quality degree, which evaluates the fault detection coverage during the testing process and the testing cost.

An integrated framework for QoS-based adaptation and exception resolution in WS-BPEL scenarios
ACM Symposium on Applied Computing, 2013In this paper, we present a framework which incorporates runtime quality of service-based adaptation for BPEL scenarios, allowing for tailoring their execution to the diverse needs of individual users. The proposed framework also caters for automatically

BPEL only supports a strictly centralized and coordinated execution of Web service compositions, but this solution is clearly not the best option in many concrete cases. The conceptually monolithic BPEL process should be executed in a distributed setting, where each peer is only responsible for a fraction of the whole process and for the coordination ...

Towards Distributed BPEL Orchestrations
Electron. Commun. Eur. Assoc. Softw. Sci. Technol., 2006Web services are imposing as the technology to integrate highly heterogeneous systems. BPEL, the standard technology to compose services, assumes a single âorchestratorâ that controls the execution flow and coordinates the interactions with selected services. This centralized approach simplifies the coordination among components, but it is also

Transforming BPEL to Petri Nets
2005We present a Petri net semantics for the Business Process Execution Language for Web Services (BPEL). Our semantics covers the standard behaviour of BPEL as well as the exceptional behaviour (e.g. faults, events, compensation). The semantics is implemented as a parser that translates BPEL specifications into the input language of the Petri net model ...

Comprehensive Monitoring of BPEL Processes
IEEE Internet Computing, 2010Service-oriented systems' distributed ownership has led to an increasing focus on runtime management solutions. Service-oriented systems can change greatly after deployment, hampering their quality and reliability. Their service bindings can change, and providers can modify the internals of their services.

Visualization of Complex BPEL Models
2010In this work, we present our approach for producing layouts of complex workflows given in the Business Process Execution Language (BPEL) [1]. BPEL is a verbose, hierarchical workflow language containing nested, alternative and concurrent execution paths.
