Architecting Modern Java EE Applications

Run admin/management tasks as one-off processes

This principle describes that administrative or management tasks should be executed as separate short-lived processes. The technology ideally supports command execution in a shell that operates on the running environment.

Although containers encapsulate Unix processes, they provide additional functionality to execute single commands or to open a remote shell into the container. Engineers can therefore execute the management and administration scripts provided by the Java EE application server. Still, in Java EE applications, the number of required administration and management tasks are limited. A Container runs the application server process, which auto-deploys the application; no further application ...
