2.1 System management overview

At first glance, system management concepts in WAS might seem complex. However, the fact that the system management architecture is based on JMX™, and the fact that WAS provides easy-to-use administration tools makes it fairly simple to use and understand.

Terminology: There are differences in how WAS handles administration depending on the environment you have set up. You will see us refer to the following when explaining these differences: - Stand-alone server environment refers to a single stand-alone server that is not managed as part of a cell. With the Base and Express packages, this is your only option. You can also create a stand-alone server with the ND package. - Distributed server environment refers to the situation where you have multiple servers managed from a single deployment manager in the cell. We also refer to these as managed servers. This is only valid with the ND package. - Managed processes refer to the deployment manager, nodes (node agents), and appservers.
