WebLogic Administrators typically use the Administration Console or the WebLogic Scripting Tool (WLST) to create and deploy (target) JDBC modules.

Note:

* (not A) Domain template—defines the full set of resources within a domain, including

infrastructure components, applications, services, security options, and general

environment and operating system options.

* Extension template—defines the applications and services that you can add to an

existing domain, including product component functionality and resources such as

JDBC or JMS.

* (not B)Each domain describes its configuration in an XML document that is located in the domain’s configuration directory. At run time, each WebLogic Server instance in a given domain creates an in-memory representation of the configuration described in this document.

The central configuration file for a domain is DOMAIN_NAME/config/config.xml. This file specifies the name of the domain and the configuration of each server instance, cluster, resource, and service in the domain. The file includes references to additional XML files that are stored in subdirectories of theDOMAIN_NAME/config directory. These included files are used to describe major subsystems of WebLogic Server.
