Summary

You can manage broadly three types of middleware with Oracle Enterprise Manager. These can be classified as open source middleware, IBM, and Microsoft middleware. Enterprise Manager supports the management of non-Oracle middleware by providing various plug-ins. Plug-ins for all open source middleware, except Tomcat, are integrated with Enterprise Manager. You can manage IBM WebSphere Application Server Cell and Websphere MQ with Enterprise Manager. Enterprise Manager also provides several plug-ins for managing Microsoft Middleware. You have to install these plug-ins as a super administrator and deploy them to an agent before you can monitor a plug-in target. You get all the benefits of alert notification, historical performance metrics, configuration, and configuration management with plug-ins. You can also use Service Level Management with third-party targets. In the next chapter, we will learn how you can diagnose problems in the JVM or Java EE applications.
