Use the administrative interfaces to create, start, and stop servers. Servers extend the ability of application servers, allowing them to handle Service Component Architecture (SCA) modules. Other server processes, such as deployment managers and node agents, can be used to manage servers.
Servers must be running before you can start applications on them. The methods for starting a server vary and depend on whether you are starting a stand-alone server or a managed server. With managed servers, the node agent must be running before you can start the servers. You can start managed servers from the administrative console of the deployment manager. If you have deployment environments or clusters, you can start or stop all of the servers in one action, from the administrative console of the deployment manager.
