# Creating Liquid Data Domains

This chapter introduces the concept of WebLogic domains, and explains how to create new WebLogic domains for BEA Liquid Data for WebLogic, or to add Liquid Data to an existing WebLogic domain. The following topics are included:

- Understanding WebLogic Domains and Administration
- Understanding the Relationship of Liquid Data to WebLogic Domains
- Creating a New Domain
- Adding Liquid Data to an Existing Domain

For detailed information about adding Liquid Data to other types of WebLogic domains, such as WebLogic Platform, WebLogic Portal, WebLogic Integration, or WebLogic Workshop domains, see Deployment Tasks in the Deployment Guide.

# Understanding WebLogic Domains and Administration

A WebLogic domain is a collection of WebLogic resources managed as a single unit. A WebLogic domain includes one or more instances of WebLogic Server and may include WebLogic Server clusters. For more information about domains, see WebLogic Server Domains in Configuring and Managing WebLogic Server.

The Administration server is the central point of control for an entire domain. If there is only one server in a domain, that server is the Administration server in addition to the other functions it provides. Any other servers in the domain are Managed servers.

# Understanding the Relationship of Liquid Data to WebLogic Domains

Liquid Data is an application and a set of associated resources that are deployed in a WebLogic domain. Starting, stopping, and managing Liquid Data is accomplished by starting the WebLogic Server in a particular domain in which Liquid Data is deployed, and using the Administration Console for that server to configure and manage Liquid Data resources for that domain. The full installation of Liquid Data includes a preconfigured Samples domain as a getting started example.

When you are ready to set up your own Liquid Data domains and servers, you must create new Liquid Data domains or add Liquid Data to your existing WebLogic Server or WebLogic Integration domains.

# Creating a New Domain

If you are creating a new WebLogic domain for use with Liquid Data, you can use the WebLogic Platform Configuration Wizard. For more information, see Creating a New WebLogic Domain in the WebLogic Platform documentation.

When you install Liquid Data into a WebLogic Platform, several Liquid Data configuration templates are installed for use with the Configuration Wizard. For details on creating these domains, as well as on extending an existing domain to use Liquid Data, see the Liquid Data Deployment Guide.

# Adding Liquid Data to an Existing Domain

Once you have WebLogic Server domain in which you want to use Liquid Data, the next step is to deploy the Liquid Data application and resources into that domain. For more information see Deployment Tasks in the Deployment Guide.
