Best practices for managing non-Oracle Java middleware

Now that we have concluded the management of non-Oracle Java middleware, here are some best practices that we recommend to get the best out of Enterprise Manager.

• You can monitor multiple installs of non-Oracle middleware targets running on multiple hosts from a single agent. If you are monitoring a large number of application server targets, do not use the agent to monitor more than 25-30 application server instances.

• Do not use an agent to monitor different types of Java targets, for example do not use an agent to monitor both JBoss Application Server and IBM WebSphere. The agent communicates with the application servers using JMX and requires client-side JAR files provided by application servers and there could be conflicting classes that could cause classloading errors at the agent side. This will result in metric collection error.

• Avoid monitoring different versions of the same application server from the same agent, unless your...
