h1. DB Worker Node Add on
The *DB Worker Node Add-on* is a all-in-one-system z2 installation comprising the z2 environment plus a database (at the moment only "H2 Database Engine":http://www.h2database.com/ is supported). The purpose is to have a quick and easy system setup like development or demonstration environments. Of course one can use it also for productive systems if the H2 database fulfills your requirements.
The add-on contains only a wrapper component that launches the H2 database in embedded mode (the h2 database jar is part of the
z2-base:source:base|com.zfabrik.db.drivers module) during z2 bootstrap. Since the wrapper is launched on a separate z2 worker node (i.e. the DB Worker node) the database runs in server mode from the web applications point of view (which are running on the web worker node).
In order to run the database within a separate process one has to configure the DB worker node in the *environment* module. This is illustrated at z2-samples:source:z2-samples-dbworker|environment, see also the [[]]
