D Configuring Oracle Database Globalization Support

This appendix describes the following Globalization Support topics:

See Also:

Oracle Database Globalization Support Guide for an overview of globalization support for Oracle Database

D.1 Installing and Using Oracle Components in Different Languages

This section describes the following procedures:

D.1.1 Configuring Oracle Components to Run in Different Languages

You can specify the language and the territory, or locale, in which you want to use Oracle components. The locale setting of a component determines the language of the user interface of the component and the globalization behavior, such as date and number formatting. Depending on the Oracle component, the locale of the component is either inherited from the operating system session that started the component, or is defined by the NLS_LANG environment variable.

The operating system locale usually influences Oracle components that are based on Java technology. The NLS_LANG environment variable usually influences Oracle components that use Oracle Client libraries such as OCI.

Note:

The user interface of an Oracle component is displayed in a selected language only if the appropriate translation is available and has been installed. Otherwise, the user interface is displayed in English.

This section describes the following procedures:

D.1.1.1 Determining the Operating System Locale

The locale setting of your operating system session determines the language of the user interface and the globalization behavior for components such as Oracle Universal Installer, Oracle Net Configuration Assistant, and Oracle Database Configuration Assistant. It also determines the globalization behavior of Oracle Database sessions created by a user application through Oracle JDBC driver, unless overridden by the application.

To set locale for the current operating system user on Windows XP, Windows 2003, and Windows Server 2003 R2, select the desired locale from the pop-up list in Standards and formats area on the Regional Options tab. On Windows Vista, Windows Server 2008, and later versions, select the desired locale from the Current format pop-up list on the Formats tab.

Some of the locales may be unavailable until you install required operating system support files. On Windows XP, Windows 2003, and Windows Server 2003 R2, make sure the relevant check boxes are checked in Supplemental language support area on Languages tab.

Some Oracle components, such as SQL*Plus, require that the Windows System Locale is also set to the language in which the components are to be run. System Locale is called Language for non-Unicode programs on Windows XP, Windows 2003, and Windows 2003 R2. On Windows XP and Windows 2003, select the locale from the pop-up list in the Language for non-Unicode programs area on the Advanced tab. On Windows Vista, Windows Server 2008, and later versions, click the Change system locale... button on the Administrative tab, accept the use of administrative privileges, if User Account Control is active, and select the locale from the pop-up list in the opened dialog box.

Note:

The operating system must be restarted after the System Locale is changed. See the operating system documentation for further information about Windows locale settings.

D.1.1.2 Configuring Locale and Character Sets Using the NLS_LANG Environment Variable

The NLS_LANG environment variable determines the language of the user interface and the globalization behavior for components such as SQL*Plus, exp, and imp. It sets the language and territory used by the client application and the database user session. It also declares the character set for entering and displaying data by the client application.

The NLS_LANG environment variable uses the following format:

NLS_LANG=language_territory.characterset

In this format:

  • language specifies the language used for displaying Oracle messages, sorting, day names, and month names

  • territory specifies the conventions for default date, monetary and numeric formats

  • characterset specifies the encoding used by the client application

    In most cases, this is the Oracle character set that corresponds to the Windows ANSI Code Page as determined by the System Locale.

The NLS_LANG parameter on Windows can be set

  • in Registry under the subkey corresponding to a given Oracle home,

  • as an environment variable.

When you install Oracle Database components and the NLS_LANG parameter is not yet set in the Registry subkey of the target Oracle home, Oracle Universal Installer sets the NLS_LANG parameter to a default value derived from the operating system locale for the current user. See the following table.

  • Spanish (Venezuela) - LATIN AMERICAN SPANISH_VENEZUELA.WE8MSWIN1252

D.1.1.3 NLS_LANG Settings in Console Mode and Batch Mode

Before you can use Oracle utilities such as SQL*Plus, SQL Loader, Import, and Export from the Command Prompt window, you may have to set the character set field of the NLS_LANG parameter to a value different than the one set in Registry.

This is required because programs running in console mode use, with a few exceptions, a different code page (character set) from programs running in GUI mode. The default Oracle home NLS_LANG parameter in the Registry is always set to the appropriate GUI code page. If you do not set the NLS_LANG parameter for the console mode session correctly, incorrect character conversion can corrupt error messages and data.

For Japanese, Korean, Simplified Chinese, Traditional Chinese, Thai, and Vietnamese, the console (OEM) code page is identical to the GUI (ANSI) code page. In this case, you are not required to set the NLS_LANG parameter. For other languages, set the correct character set value of NLS_LANG by issuing a SET NLS_LANG command in the same Command Prompt window in which you want to start the affected utility.

Similarly, in batch mode, set the correct character set value of NLS_LANG by inserting a SET NLS_LANG command at the start of the batch procedure, according to the character set of the files to be processed in the procedure.

To find the current console code page, issue the CHCP command in the Command Prompt window. Use the reported code page number to look up the corresponding Oracle character set name in Table D-1.

Table D-1 lists the Oracle character sets that correspond to the console mode code pages.

D.1.2 Installing Translation Resources

To view the user interface of Oracle components in different languages, you must install the appropriate language translations along with the component.

Note:

Part of Oracle Database Vault user interface text is stored in database tables in the DVSYS schema. By default, only the English language is loaded into these tables. You can use Oracle Database Vault Configuration Assistant to add more languages to Oracle Database Vault. For the necessary steps, see Appendix C in Oracle Database Vault Administrator's Guide

To install translation resources:

  1. Start Oracle Universal Installer.

  2. In the Configure Security Updates screen enter the relevant information and click Next.

  3. In the Download Software Updates and Apply Software Updates screens, enter the relevant information and click Next.

  4. In the Select Installation Option screen, select the installation option and click Next.

  5. In the System Class screen, select the type of system class for installing the database, and click Next.

  6. In the Grid Installation Options screen, select the type of database installation you want to perform, and click Next.

  7. In the Select Product Languages screen, select the language in which you want to run the product from the Available Languages field.

    Note:

    The Available Languages field lists all languages supported by Oracle globalization libraries. The set of languages for which a translation is actually available is usually smaller and depends on a particular component. The scope of translation for a given component may differ between languages. For example, some translations may include all user interface text, while others may include only error messages and no help files.
  8. Use the > arrow to move the selected language to the Selected Languages field, and then click Next.

    Note:

    Oracle Universal Installer ignores languages in the Selected Languages field for which no translation is available.

D.2 Running Oracle Universal Installer in Different Languages

The operating system locale determines the language in which Oracle Universal Installer runs. Oracle Universal Installer may run in one of the following languages:

  • Brazilian Portuguese

  • English

  • French

  • German

  • Italian

  • Japanese

  • Korean

  • Simplified Chinese

  • Spanish

  • Traditional Chinese

To run Oracle Universal Installer in a desired language

  1. Change the locale for the operating system user and the System Locale as described in the "Determining the Operating System Locale" section.

  2. Run Oracle Universal Installer by following the instructions in the "Installing the Oracle Database Software" section.

If the selected language is not one of the listed earlier, Oracle Universal Installer runs in English.
