2 Creating a WebLogic Domain

You can create a new WebLogic domain by using the Configuration Wizard in graphical mode. Depending on your domain requirements and customizations, the Configuration Wizard takes you through a series of screens during the domain creation process.

This chapter includes the following sections:

• Setting the CONFIG_JVM_ARGS Environment Variable
  Before you start the Configuration Wizard, set a value for the CONFIG_JVM_ARGS environment variable. Setting the appropriate value for the variable enables you to specify the type of domain you want to create, whether expanded or compact.
• Domain Creation Process
  You can use the Configuration Wizard to create a WebLogic domain, by selecting either the product components to include in your domain or by selecting the template JAR files. If necessary, you can also customize the domain to suit your environment.
• Domain Version Restrictions
  When you create a domain by using a custom template, either by using WLST or the Create Domain Using Custom Template option on the Templates screen of the Configuration Wizard, you have to keep a few restrictions in mind.
• Starting the Configuration Wizard
  You can start the Configuration Wizard in graphical mode either from the Windows Start menu or from the command line. The console for the machine on which the product installation resides must support Java-based GUIs.
• Creating a WebLogic Domain in Graphical Mode
  The Configuration Wizard takes you through a series of screens that help you create a WebLogic Server domain. Additional screens appear depending on the components that you add for the domain, and on other factors.
• Starting the Administration Server
  You can start the Administration Server after you create the domain.
• Running the Quick Start Configuration Wizard
  The Quick Start Configuration Wizard helps you configure the sample domains and the Fusion Middleware product domains that use the Derby (JavaDB) database driver.

Setting the CONFIG_JVM_ARGS Environment Variable

Before you start the Configuration Wizard, set a value for the CONFIG_JVM_ARGS environment variable. Setting the appropriate value for the variable enables you to specify the type of domain you want to create, whether expanded or compact.

Set the value to -Djava.security.egd=file:/dev/./urandom to reduce the time the Configuration Wizard takes to create or update a domain.

In addition, if you want to create a compact domain on either Windows or Linux, include the following value for the CONFIG_JVM_ARGS environment variable: -Dcom.oracle.cie.config.showProfile=true

This setting causes domain profile selections (compact and expanded) to appear on the Configuration Type screen of the Configuration Wizard. For more information about domain profiles, see Domain Topology Profiles in Domain Template Reference.

Domain Creation Process

You can use the Configuration Wizard to create a WebLogic domain, by selecting either the product components to include in your domain or by selecting the template JAR files. If necessary, you can also customize the domain to suit your environment.

Table 2-1 shows the sequence of the Configuration Wizard screens. The screens that you see depend on your domain requirements and whether you need to customize your domain.

You may 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.

Domain Version Restrictions

When you create a domain by using a custom template, either by using WLST or the Create Domain Using Custom Template option on the Templates screen of the Configuration Wizard, you have to keep a few restrictions in mind.

The restrictions include the following:

• The versions of the WebLogic Server templates that were used to create the custom domain and custom domain template must be the same version as the WebLogic Server installation in which the domain is used. For example, if you created a WebLogic domain by using the WebLogic Server Base Domain 10.3.6 template, and then created a custom domain template from that domain, you cannot use the custom domain template to create a domain in a WebLogic Server 12.2.1 installation.

• If you want to create a custom domain template that was created from a domain from a previous version of WebLogic Server, you must first upgrade that domain to the WebLogic Server version in which you want to use the domain. You can upgrade the domain by using either WLST or the Fusion Middleware Reconfiguration Wizard. For more information about the Reconfiguration Wizard screen, click Help on the relevant screen.

For more information about domain version restrictions, see Domain Restrictions in Understanding Domain Configuration for Oracle WebLogic Server.

Starting the Configuration Wizard

You can start the Configuration Wizard in graphical mode either from the Windows Start menu or from the command line. The console for the machine on which the product installation resides must support Java-based GUIs.

• To start the Configuration Wizard in graphical mode on a Windows platform, choose Start > All Programs > Oracle > Oracle Home > WebLogic Server version > 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: ORACLE_HOME/oracle_common/common/bin

     On UNIX: ORACLE_HOME/oracle_common/common/bin

     Replace ORACLE_HOME with the Oracle Home directory that was specified during installation.

  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 appears if the default 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.

     To create a log file of the Configuration Wizard session, include the -log=config.log -log_priority=debug parameter in the command. You can specify any file name for the log file, such as config_today.log. The log file is stored in the logs directory of the Oracle Home directory. Other valid values for log_priority are OFF, SEVERE, WARNING, INFO, CONFIG, FINE, FINER, FINEST, and ALL.

     The Configuration Type screen appears.

Creating a WebLogic Domain in Graphical Mode

The Configuration Wizard takes you through a series of screens that help you create a WebLogic Server domain. Additional screens appear depending on the components that you add for the domain, and on other factors.

To create a new WebLogic Domain, start the Configuration Wizard as described in Starting the Configuration Wizard.

Note:

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

If your installation includes Fusion Middleware products, see Configuring Fusion Middleware Domains, for instructions. Fusion Middleware product configuration includes additional Configuration Wizard screens that are not included in the workflow in this chapter.

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 Configuration Wizard Screens, or click the link in the Screen column.

Starting the Administration Server

You can start the Administration Server after you create the domain.

For more information about the various methods that you can use to start the Administration Server, see Starting and Stopping Servers in Administering Server Startup and Shutdown for Oracle WebLogic Server.

Running the Quick Start Configuration Wizard

The Quick Start Configuration Wizard helps you configure the sample domains and the Fusion Middleware product domains that use the Derby (JavaDB) database driver.

You can run the wizard automatically or manually depending on the domain type (sample or product) that you want to configure, as described below:

• To configure the various sample domains, such as MedRec and the Examples Server, in your WebLogic Server installation, run the wizard by selecting the Automatically Launch Quick Start Configuration Wizard option on the Installation Complete screen of the WebLogic Server installer.

• To configure Fusion Middleware product domains, run the wizard manually as described in this section. Schema JARs that are provided with the product is used to populate a domain_home/common/db directory.

Note:

The Quick Start Configuration Wizard supports only the Derby (JavaDB) database driver. If you are using another database, you cannot use the Quick Start Configuration Wizard to create your domain.

Before you run the Configuration Wizard manually in the Quick Start mode, you must set the CONFIG_JVM_ARGS environment variable to specify the full path and JAR file name for each template that you want to use for the domain. For the location and filename of templates provided by Oracle for WebLogic Server and other Fusion Middleware products, see the following resources in Domain Template Reference.

• WebLogic Server Templates

• Fusion Middleware Product Templates

Windows

To set CONFIG_JVM_ARGS on a Windows system:

set CONFIG_JVM_ARGS="-DuserTemplates=template1,template2,template3, ..., templaten"

The following example uses the WebLogic Server base domain template and the Web Services JAX-WS template to create the domain:

set CONFIG_JVM_ARGS="-DuserTemplates=C:/Oracle/Middleware/wlserver/common/
templates/wls/wls.jar,C:/Oracle/Middleware/wlserver/common/templates/
wls/wls_webservice_jaxws.jar"

To run the Configuration Wizard in Quick Start mode on Windows systems, enter the following commands, where ORACLE_HOME is your Oracle home directory:

cd ORACLE_HOME/oracle_common/common/bin
config.cmd -target=config-oneclick

UNIX

To set CONFIG_JVM_ARGS on a UNIX or Linux system:

export CONFIG_JVM_ARGS="-DuserTemplates=template1,template2,template3, ..., templaten"

The following example uses the WebLogic Server base domain template and the Web Services JAX-WS template to create the domain:

export CONFIG_JVM_ARGS="-DuserTemplates=/Oracle/Middleware/wlserver/common/
templates/wls/wls.jar,/Oracle/Middleware/wlserver/common/templates/
wls/wls_webservice_jaxws.jar"

To run the Configuration Wizard in Quick Start mode on UNIX systems, enter the following commands, where ORACLE_HOME is your Oracle home directory:

cd ORACLE_HOME/oracle_common/common/bin
config.sh -target=config-oneclick

Table 2-4 shows the sequence of the Quick Start Configuration Wizard screens:

3	Configuration Success	Always	Review the domain creation results. Click Finish to exit the Configuration Wizard.

• Using Quick Start to Create the WebLogic Sample Domains
  The Quick Start Wizard helps you create the WebLogic sample domains during the installation process. You can also run the wizard from the command line.

Using Quick Start to Create the WebLogic Sample Domains

The Quick Start Wizard helps you create the WebLogic sample domains during the installation process. You can also run the wizard from the command line.

If you are running the wizard from the command line, you must create the sample domains one at a time. This process requires you to run the Quick Start Wizard three times to create all three domains.

Refer to Table 2-5 for the templates that you must include in the CONFIG_JVM_ARGS variable to create each domain. For example, to create the WebLogic Server Examples domain, enter the following commands, substituting your WebLogic Server home directory for WL_HOME:

set CONFIG_JVM_ARGS="-DuserTemplates=WL_HOME/common/
templates/wls/wls.jar,WL_HOME/common/templates/wls/wls_default.jar,
WL_HOME/common/templates/wls/wls_examples.jar"

cd ORACLE_HOME/oracle_common/common/bin
config.sh -target=config-oneclick
