4.2 Joint Draw Pad The JDP is a tool for making joint figures or designs. The users may be in different locations but they can draw or make a design in the same pad. For the sake of space, we show in Fig. 10 and Fig. 11 the display for Windows XP and Mac. In fact, in Fig. 10 (Windows XP) is drawn the circle and this circle is shown at the same time in other environments. The heart is drawn in Linux, the rectangular shape is drawn in Mac, and the triangular shape is drawn in UNIX. This tool also can be used for collaboration research from different sites. 4.3 Shared Web Browser The SWB application tool is shown in Fig. 12 and Fig. 13 for Windows XP and UNIX, respectively. Using this application, the peers in the same room can see the same URL. In these figures is shown the homepage of Fukuoka Institute of Technology (FIT), Japan. This tool is very useful application and can be used for collaboration research. For example if one peer finds an interesting homepage with good papers and research work, he can send this information to other peers. Thus, they can work efficiently together. 4.4 Subaru Avatar Another application tool is SA. For using this tool, the peer prepares a room, then changes from Mode to Discussion. Next, he pushes the Login button. Then, when the user moves the mouse in the direction he wants, the avatar follows the mouse movement. In this application, there is a text field. If the peer writes something in the text field, the information will be shown in the peerís avatar. In this way, the peers can communicate and exchange the information with each other. The capture display for Linux and Mac are shown in Fig. 14 and Fig. 15, respectively. The SA can be used as a chat application between peers for communication in real time. 5. CONCLUSIONS In this paper, we improved our previous platform TOMSCOP and implemented a multiplatform P2P system called M3PS. Different from many other similar platforms, it has adopted a pure P2P architecture and each peer has to administrate collaborative rooms. To demonstrate the platform effectiveness, we showed four application tools: INFO, JDP, SWB and SA. By many experiments, we found that proposed M3PS operates smoothly in the four environments. As the future work, we will deal with following issues: • secure room administration in P2P communication; • audio and video communications; • efficient pipe advertisement creation to avoid creating duplicated pipe advertisement for a room; • development of new shared applications. 6.

Mapping Clouds of SOA- and Business-related Events for an Enterprise Cockpit in a Java-based Environment Daniel Jobst TietoEnator Deutschland GmbH Digital Innovations 80335 München, Germany Daniel.Jobst@tietoenator.com Gerald Preissler Deutsche Post AG SOPSOLUTIONS® 53250 Bonn, Germany G.Preissler@deutschepost.de ABSTRACT This paper is about business process management (BPM) and business activity monitoring (BAM) using event processing. We will show why the management of business processes is important for all further steps towards an event-driven and real time enterprise. That is process automation using workflow engines and standards like the Web Service Business Process Execution Language (BPEL). As an underlying middleware platform we use the service oriented platform SOPware of Deutsche Post AG. Events are emitted from all layers, the middleware platform layer and the business process layer, and figuratively build “event clouds”. Event processing functionalities will correlate both “event clouds” and feed business activity monitoring. There, enterprise performance cockpits and dashboards depict the performance of the enterprise and of its processes. Categories and Subject Descriptors D.2.11 [Software Architectures]: patterns – service oriented architecture, event processing. D.2.8 [Metrics]: Process metrics – business activity monitoring, enterprise cockpit. D.3.2 [Language Classifications]: Object-oriented languages – Java, J2EE. General Terms Management, Measurement, Performance, Design, Standardization. Keywords Service oriented architecture, event processing, business activity monitoring. 1. TECHNOLOGIES AND ARCHITECTURE In the following chapters we will concentrate on how to do monitoring better rather than the question what it is for. We will take into account recent developments in IT architecture and event processing technology. 1.1 Business process management (BPM) According to the latest Gartner research paper on process management, today BPM is more than a collection of software tools. BPM is a management discipline with modeled business processes as its fulcrum. It aims to improve enterprise agility and the operational performance. Decisive BPM technologies are process modeling, process execution, a BPM suite, and accessing underlying resources using service orientated technologies. [1] As modeling tool and modeling environment we are using the ARIS toolset in our use case. Processes in their finest granularity will be denoted in the Event-driven Process Chain (EPC) . According to [2] and the monitoring and event processing approach we are discussing in this paper, focusing on processes and explicit process models are vital for further process measurement and monitoring. 1.2 Process automation and service orientation According to the approach we are introducing in this paper, process automation needs some preconditions. First of all, it needs process models in the right granularity for SOA. The modeled process steps have to match the appropriate service calls or sub processes in the later automated processes. Then it needs a service oriented platform with concepts providing for services like authorization, authentication, user management, data management, logging, exception handling, monitoring, and security. SOPware is a Java-based infrastructure that allows the easy integration of J2EE and J2SE-based applications in an SOA environment. Thirdly, process automation needs a standardized process language which can be executed by a workflow engine much like a programming language. The Business Process Execution Language is such a language which is designed to orchestrate web services. For the current version 1.1 (BPEL4WS) and version 2.0 (WSBPEL) see [4]. 1.3 Business activity monitoring (BAM) BAM as a technology gives access to key business metrics. It is used to monitor business objectives, to evaluate operational risk, and to reduce the action time between an event happening and the actions taken [5]. According to [6], BAM incorporates the different technologies like BPM, BPEL, event processing, and SOA. It links events, services, and processes with rules, notifications, and human interaction. Results of BAM are needed for controlling an enterprise and are important for other methodologies like the balanced scorecard (BSC) and Six Sigma or for compliance with regulations like the Sarbanes Oxley Act (SOX) or Basel II. 1.4 Event processing (EP) Each enterprise has to deal with a huge number of events. These events can be low level network events or high level business events. All of them have some kind of representations in the IT system. In order to deal in real time with a huge number of events, EP provides different technologies and methodologies. One is to classify events in different hierarchical layers, to look for patterns of events within a layer, and propagate new complex events to 230
