Named datasources represent database connections used by Oracle ATG Web Commerce applications.

The modulelist-server-instance attribute identifies a server-instance-type, which in turn supplies a list of modules. The dbinit.xml files for each of those modules are then used to generate the SQL and import scripts that run for the database.

You can declare named datasources in the product.xml file for configuration by end-users.

<named-datasource id="management" modulelist-server-instance-
type="management">
     <title resource-key="">Publishing</title>
     <jndi>atgpub_ds</jndi>
</named-datasource>

In order for a named datasource to be used, it must be included in a server-instance-type that has at least one server instance. Each server-instance of that type will have the named datasource’s JNDI registered with the application server.
