2.7 Business Monitor This section describes best practices for performance with Business Monitor V8.0. 2.7.1 Event processing 2.7.2 Dashboard A major factor in event processing performance is tuning the Business Monitor database. Ensure adequate buffer pool sizes to minimize disk reading activity and placement of the database logs, which ideally is on a physically separate disk subsystem from the database table spaces. By default, events are delivered from CEI to the monitor database, bypassing an intermediate queue. We suggest using this default delivery style for better performance because it avoids an additional persistence step in the flow. For additional background, see “Receiving events using table-based event delivery” in the IBM Business Monitor V8.0 information center: http://pic.dhe.ibm.com/infocenter/dmndhelp/v8r0m1/index.jsp?topic=/com.ibm.wbpm.mo n.imuc.doc/inst/cfg_qb.html The platform requirements of Business Space and the Business Monitor widgets on the dashboard are relatively modest compared to the Business Monitor server and the database server. The most important consideration for good dashboard performance is to size and configure the database server correctly. Be sure that it has enough processor capacity for anticipated data mining queries, enough memory for buffer pools, and plenty of disk arms. 2.7.3 Database server Both event processing and dashboard rely on a fast, well-tuned database server for good performance. The design of the Business Monitor assumes that any customer using it has strong onsite database administrator skills. It is important to apply the database tuning suggestions beginning in 4.13, “General database tuning” on page 80. 22 IBM Business Process Manager V8.0 Performance Tuning and Best Practices
3 Chapter 3. Development best practices This chapter presents best practices that are relevant to solution developers. It addresses modeling, design, and development choices that are made while designing and implementing a Business Process Manager V8.0 solution. Business Process Manager Advanced Edition offers two authoring environments. These authoring environments both interact with the Process Center, which is a shared repository and runtime environment. ► ► In the Process Designer environment, you can model, develop, and deploy BPMN business processes, which often have human interactions. The Process Designer is the only authoring tool for Business Process Manager V8.0 Standard Edition. In the Integration Designer environment, you can build and implement services that are automated or that start other services, such as web services, enterprise resource applications, or applications running in CICS and IMS. These services and applications exist in the enterprise. It is also the tool to use to author Business Process Execution Language (BPEL) business processes. Two individuals with separate roles and skill sets work together when developing Business Process Manager applications. These roles correspond to the Process Designer and Integration Designer environments. ► ► The business author is responsible for authoring all business processes. The business author is able to use services but is not interested in the implementation details or how they work. The business author uses Process Designer to create business process diagrams (BPDs), and utilizes advanced integration services (AISs) to collaborate with the integration programmer. The integration programmer is responsible for doing all of the integration work necessary to support the processes the business author creates. For example, the integration programmer implements all the AISs and produces mappings between back-end formats and the requirements of current applications. The integration programmer uses Integration Designer. The remainder of this chapter is organized based on the type of user, with separate sections describing Process Designer (business author) and Integration Designer (integration programmer) best practices. Additionally, the chapter provides developer considerations for browser environments, and for WebSphere InterChange Server migration. © Copyright IBM Corp. 2013. All rights reserved. 23
