2 Creating a WebLogic Domain

This chapter describes how to create a new WebLogic domain by using the Configuration Wizard in graphical mode. It contains the following sections:

Domain Creation Process
Starting the Configuration Wizard in Graphical Mode
Creating a WebLogic Domain in Graphical Mode
Starting the Administration Server

Domain Creation Process

The Configuration Wizard guides you through the process of creating a WebLogic domain for your target environment by selecting the product components to include in your domain, or by selecting domain template JAR files. If necessary, you can also customize the domain to suit your environment by adding and configuring Managed Servers, clusters, and machine definitions, or customizing predefined JDBC data sources and JMS file store directories.

You might want to customize your domain in the following circumstances:

To create a multi-server or clustered domain when using the default settings. All the predefined WebLogic Server templates (those delivered with WebLogic Server) create single-server domains.
To use a database that is different from the default database in the domain or extension template. In this case, you must customize the JDBC settings to point to the appropriate database.
To customize the listen port and the SSL port.
To create a test environment by using a domain template that you received, and to modify the domain configuration to work in the test environment based on your requirements.

Figure 2-1 summarizes the Configuring Wizard steps for creating a WebLogic domain. The steps indicated in boxes with dashed lines are relevant only when you create WebLogic domains that contain specific products, such as those that use RCU and those that require JDBC data sources.

Starting the Configuration Wizard in Graphical Mode

The console for the machine on which the product installation resides must support Java-based GUIs. All Windows-based consoles support Java-based GUIs; only a subset of UNIX-based consoles support Java-based GUIs.

Note:

If you attempt to start the Configuration Wizard in graphical mode on a system that cannot support graphical display, the Configuration Wizard automatically starts in console mode.

You can start the Configuration Wizard in graphical mode from either the Windows Start menu or from the command line.

To start the Configuration Wizard in graphical mode on a Windows platform, choose Start > Programs > Oracle WebLogic > WebLogic Server > Tools > Configuration Wizard.
To start the Configuration Wizard in graphical mode from a Windows command prompt or on UNIX systems:
1. Log in to the system on which the product is installed.
2. Open an MS-DOS command prompt window (on Windows) or a command shell (on UNIX).
3. Go to the following directory:
  
  On Windows: WLHOME\common\bin
  
  On UNIX: WLHOME/common/bin
  
  where WLHOME is the directory in which WebLogic Server is installed.
4. Execute the following command:
  
  On Windows: config.cmd
  
  On UNIX: sh config.sh
  
  Note:
  When you run the config.cmd or config.sh command, the following error message might be displayed to indicate that the defalut cache directory is not valid:
  *sys-package-mgr*: can't create package cache dir
  
  You can change the cache directory by including the -Dpython.cachedir=valid_directory option in the command line.
  
  The Welcome screen is displayed.

Creating a WebLogic Domain in Graphical Mode

To create a new WebLogic Domain by using the Configuration Wizard in graphical mode, start the Configuration Wizard as described in Starting the Configuration Wizard in Graphical Mode.

Note:

In situations where you cannot run the Configuration Wizad in GUI mode, Oracle recommends that you use a WLST script to create or extend a domain. For more information, see "Creating and Using a Domain Template (Offline)" in Oracle WebLogic Scripting Tool.

The Configuration Wizard displays a sequence of screens, in the order listed in Table 2-1. For more information on each screen, refer to the related section in Chapter 4, "Configuration Wizard Screens," or click the link in the Screen column.
