IBM Tivoli Composite Application Manager (ITCAM) for WebSphere has JMX monitoring capability. This document discusses how to monitor custom MBeans registered in WebSphere Application Server v6.1 using ITCAM for WebSphere v6.1.

A composite application is a distributed implementation of an application, in which it spans several application servers and crosses platform boundaries. This circumstance can create an operations challenge. The condition has gotten worse with the advent of Service-Oriented Architecture (SOA) because many applications have become loosely coupled, meaning that programs can find connections and services at run time, depending on the available environment. Operations management for composite applications is a complex issue. Applications are generally designed based on functionality, not manageability. An operator has to rely on management tools to decode any problem on these applications and recover them. This paper describes an approach for designing a management solution for operators to manage composite applications. It also provides step-by-step instructions for implementing this solution for a sample application, the Trader application, which has been enhanced with Web Services calls and access to Enterprise Service Bus (ESB) mediation functions.

Service-oriented architecture (SOA) is a major new trend for application architecture. It allows you to build applications as components as defined using a Web Services Description Language (WSDL) file. You can implement applications in different servers, even different platforms. You can modify application components and workflow logic easily in execution, allowing a flexible application structure. Implementation of the client and the server side is also masked by the use of enterprise service bus, which allows a different server implementation to be provided without the need to modify the client, or, different clients can use the same server implementation. The highly flexible and distributed nature of SOA-based applications is its primary strength and the source of its appeal. However, when a problem arises, this flexible nature also causes a greater problem in pinpointing the source of problem. SOA also requires a disciplined management effort to ensure that operational changes do not disrupt overall availability. The IBM Tivoli Composite Application Manager (ITCAM) family of products directly assists services specialists who implement and manage distributed applications. We illustrate the management needs for SOA-based applications and demonstrate how Tivoli products can address these application environment needs. The overall solution that we use includes ITCAM for SOA, ITCAM for WebSphere, ITCAM for Response Time Tracking, OMEGAMON XE for Messaging, and Tivoli Business Service Manager. Services special

This IBM® Redpaper discusses large-scale implementation of IBM Tivoli® Composite Application Manager for WebSphere® and IBM Tivoli Composite Application Manager for Response Time Tracking. Large-scale implementation is typically characterized by the number of monitoring agents deployed and the number of transactions load-managed. A typical large-scale implementation of a monitoring product contains the following challenges: - Keeping up the performance of the monitoring tools to accommodate the processing load from the agents. - Automation of installation, update, and maintenance of monitoring agents based on silent installation and automated update. - Specific day-to-day maintenance actions to ensure performance and availability of the monitoring solution. This IBM Redpaper addresses these issues with regard to the implementation of ITCAM for WebSphere and ITCAM for Response Time Tracking on distributed platforms. The discussion is divided into planning issues, implementation guides, and maintenance considerations.
