13 Customizing Locale Data

Overview of the Oracle Locale Builder Utility

The Oracle Locale Builder offers an easy and efficient way to customize locale data. It provides a graphical user interface through which you can easily view, modify, and define locale-specific data. It extracts data from the text and binary definition files and presents them in a readable format so that you can process the information without worrying about the formats used in these files.

The Oracle Locale Builder manages four types of locale definitions: language, territory, character set, and linguistic sort. It also supports user-defined characters and customized linguistic rules. You can view definitions in existing text and binary definition files and make changes to them, or create your own definitions.

The Oracle Locale Builder User Interface

Ensure that the ORACLE_HOME parameter is set before starting Oracle Locale Builder.

In the UNIX operating system, start the Oracle Locale Builder by changing into the $ORACLE_HOME/nls/lbuilder directory and issuing the following command:

% ./lbuilder

In a Windows operating system, start the Oracle Locale Builder from the Start menu as follows: Start > Programs > Oracle-OraHome10 > Configuration and Migration Tools > Locale Builder. You can also start it from the DOS prompt by entering the %ORACLE_HOME%\nls\lbuilder directory and executing the lbuilder.bat command.

When you start the Oracle Locale Builder, the screen shown in Figure 13-1 appears.

Oracle Locale Builder Pages and Dialog Boxes

Before using Oracle Locale Builder for a specific task, you should become familiar with the following tab pages and dialog boxes:

• Existing Definitions Dialog Box

• Session Log Dialog Box

• Preview NLT Tab Page

• Open File Dialog Box

  Note:

  Oracle Locale Builder includes online help.

Existing Definitions Dialog Box

When you choose New Language, New Territory, New Character Set, or New Linguistic Sort, the first tab page that you see is labelled General. Click Show Existing Definitions to see the Existing Definitions dialog box.

The Existing Definitions dialog box enables you to open locale objects by name. If you know a specific language, territory, linguistic sort (collation), or character set that you want to start with, then click its displayed name. For example, you can open the AMERICAN language definition file as shown in Figure 13-2.

Figure 13-2 Existing Definitions Dialog Box

Description of "Figure 13-2 Existing Definitions Dialog Box"

Choosing AMERICAN opens the lx00001.nlb file. An NLB file is a binary file that contains the settings for a specific language, territory, character set, or linguistic sort.

Language and territory abbreviations are for reference only and cannot be opened.

Session Log Dialog Box

Choose Tools > View Log to see the Session Log dialog box. The Session Log dialog box shows what actions have been taken in the current session. Click Save Log to keep a record of all changes. Figure 13-3 shows an example of a session log.

Figure 13-3 Session Log Dialog Box

Description of "Figure 13-3 Session Log Dialog Box"

Preview NLT Tab Page

The NLT (National Languare Text) file is an XML file with the file extension .nlt that stores the settings for a specific language, territory, character set, or linguistic sort. The Preview NLT tab page presents a readable form of the file so that you can see whether the changes you have made are correct. You cannot modify the NLT file from the Preview NLT tab page. You must use the specific tools and procedures available in Oracle Locale Builder to modify the NLT file.

Figure 13-4 shows an example of the Preview NLT tab page for a user-defined language called AMERICAN FRENCH.

Figure 13-4 Previewing the NLT File

Description of "Figure 13-4 Previewing the NLT File"

Open File Dialog Box

You can see the Open File dialog box by choosing File > Open > By File Name. Then choose the NLB (National Language Binary) file that you want to modify or use as a template. An NLB file is a binary file with the file extension .nlb that contains the binary equivalent of the information in the NLT file. Figure 13-5 shows the Open File dialog box with the lx00001.nlb file selected. The Preview pane shows that this NLB file is for the AMERICAN language.

Figure 13-5 Open File Dialog Box

Description of "Figure 13-5 Open File Dialog Box"

Creating a New Language Definition with Oracle Locale Builder

This section shows how to create a new language based on French. This new language is called AMERICAN FRENCH. First, open FRENCH from the Existing Definitions dialog box. Then change the language name to AMERICAN FRENCH and the Language Abbreviation to AF in the General tab page. Retain the default values for the other fields. Figure 13-6 shows the resulting General tab page.

Figure 13-6 Language General Information

Description of "Figure 13-6 Language General Information"

The following restrictions apply when choosing names for locale objects such as languages:

• Names must contain only ASCII characters

• Names must start with a letter

• Language, territory, and character set names cannot contain underscores

The valid range for the Language ID field for a user-defined language is 1,000 to 10,000. You can accept the value provided by Oracle Locale Builder or you can specify a value within the range.

Figure 13-7 shows how to set month names using the Month Names tab page.

Figure 13-7 Month Names Tab Page

Description of "Figure 13-7 Month Names Tab Page"

All names are shown as they appear in the NLT file. If you choose Yes for capitalization, then the month names are capitalized in your application, but they do not appear capitalized in the Month Names tab page.

Figure 13-8 shows the Day Names tab page.

Figure 13-8 Day Names Tab Page

Description of "Figure 13-8 Day Names Tab Page"

You can choose day names for your user-defined language. All names are shown as they appear in the NLT file. If you choose Yes for capitalization, then the day names are capitalized in your application, but they do not appear capitalized in the Day Names tab page.

Figure 13-9 shows the Common Info tab page.

Figure 13-9 Common Info Tab Page

Description of "Figure 13-9 Common Info Tab Page"

You can display the territories, character sets, Windows character sets, and linguistic sorts that have associations with the current language. In general, the most appropriate or the most commonly used items are displayed first. For example, with a language of FRENCH, the common territories are FRANCE, BELGIUM, CANADA, and DJIBOUTI, while the character sets for supporting French are WE8ISO8859P1, WE8MSWIN1252, AL32UTF8, and WE8ISO8859P15. As WE8MSWIN1252 is more common than WE8ISO8859P1 in a Windows environment, it is displayed first.

Creating a New Territory Definition with the Oracle Locale Builder

This section shows how to create a new territory called REDWOOD SHORES and use RS as a territory abbreviation. The new territory is not based on an existing territory definition.

The basic tasks are as follows:

• Assign a territory name

• Choose formats for the calendar, numbers, date and time, and currency

Figure 13-10 shows the General tab page with REDWOOD SHORES specified as the Territory Name, 1001 specified as the Territory ID, and RS specified as the Territory Abbreviation.

Figure 13-10 General Tab Page for Territories

Description of "Figure 13-10 General Tab Page for Territories"

The valid range for Territory ID for a user-defined territory is 1000 to 10000.

If you want to print the code chart, then click Print Page.

Creating a New Character Set Definition with the Oracle Locale Builder

You can customize a character set to meet specific user needs. You can extend an existing encoded character set definition. User-defined characters are often used to encode special characters that represent the following language elements:

• Proper names

• Historical Han characters that are not defined in an existing character set standard

• Vendor-specific characters

• New symbols or characters that you define

This section describes how Oracle Database supports user-defined characters. It includes the following topics:

• Character Sets with User-Defined Characters

• Oracle Database Character Set Conversion Architecture

• Unicode 5.0 Private Use Area

• User-Defined Character Cross-References Between Character Sets

• Guidelines for Creating a New Character Set from an Existing Character Set

• Example: Creating a New Character Set Definition with the Oracle Locale Builder

Oracle Database Character Set Conversion Architecture

The code point value that represents a particular character can vary among different character sets. A Japanese kanji character is shown in Figure 13-21.

Figure 13-21 Japanese Kanji Character

Description of "Figure 13-21 Japanese Kanji Character"

The following table shows how the character is encoded in different character sets.

Unicode Encoding	JA16SJIS Encoding	JA16EUC Encoding	JA16DBCS Encoding
4E9C	889F	B0A1	4867

Oracle Database defines all character sets with respect to Unicode 5.0 code points. That is, each character is defined as a Unicode 5.0 code value. Character conversion takes place transparently by using Unicode as the intermediate form. For example, when a JA16SJIS client connects to a JA16EUC database, the character shown in Figure 13-21 has the code point value 889F when it is entered from the JA16SJIS client. It is internally converted to Unicode (with code point value 4E9C), and then converted to JA16EUC (code point value B0A1).

Example: Creating a New Character Set Definition with the Oracle Locale Builder

This section shows how to create a new character set called MYCHARSET with 10001 for its Character Set ID. The example uses the WE8ISO8859P1 character set and adds 10 Chinese characters.

Figure 13-22 shows the General tab page for MYCHARSET.

Figure 13-22 General Tab Page for MYCHARSET

Description of "Figure 13-22 General Tab Page for MYCHARSET"

Click Show Existing Definitions and choose the WE8ISO8859P1 character set from the Existing Definitions dialog box.

The ISO Character Set ID and Base Character Set ID fields are optional. The Base Character Set ID is used for inheriting values so that the properties of the base character set are used as a template. The Character Set ID is automatically generated, but you can override it. The valid range for a user-defined character set ID is 8000 to 8999 or 10000 to 20000.

Note:

If you are using Pro*COBOL, then choose a character set ID between 8000 and 8999.

The ISO Character Set ID field remains blank for user-defined character sets.

In this example, the Base Character Set ID field remains blank. However, you can specify a character set to use as a template. The settings in the Type Specification tab page must match the type settings of the base character set that you enter in the Base Character Set ID field. If the type settings do not match, then you will receive an error when you generate your custom character set.

Figure 13-23 shows the Type Specification tab page.

Figure 13-23 Type Specification Tab Page

Description of "Figure 13-23 Type Specification Tab Page"

The Character Set Category is ASCII_BASED. The BYTE_UNIQUE button is checked.

When you have chosen an existing character set, the fields for the Type Specification tab page should already be set to appropriate values. You should keep these values unless you have a specific reason for changing them. If you need to change the settings, then use the following guidelines:

• FIXED_WIDTH is used to identify character sets whose characters have a uniform length.

• BYTE_UNIQUE means that the single-byte range of code points is distinct from the multibyte range. The code in the first byte indicates whether the character is single-byte or multibyte. An example is JA16EUC.

• DISPLAY identifies character sets that are used only for display on clients and not for storage. Some Arabic, Devanagari, and Hebrew character sets are display character sets.

• SHIFT is used for character sets that require extra shift characters to distinguish between single-byte characters and multibyte characters.

  See Also:

  "Variable-width multibyte encoding schemes" for more information about shift-in and shift-out character sets

Figure 13-24 shows how to add user-defined characters.

Figure 13-24 Importing User-Defined Character Data

Description of "Figure 13-24 Importing User-Defined Character Data"

Open the Character Data Mapping tab page. Highlight the character that you want to add characters after in the character set. In this example, the 0xff local character value is highlighted.

You can add one character at a time or use a text file to import a large number of characters. In this example, a text file is imported. The first column is the local character value. The second column is the Unicode value. The file contains the following character values:

88a2 963f 88a3 54c0 88a4 611b 88a5 6328 88a6 59f6 88a7 9022 88a8 8475 88a9 831c 88aa 7a50 88ab 60aa

Choose File > Import > User-Defined Characters Data.

Figure 13-25 shows that the imported characters are added after 0xff in the character set.

Description of "Figure 13-25 New Characters in the Character Set"

Creating a New Linguistic Sort with the Oracle Locale Builder

This section shows how to create a new multilingual linguistic sort called MY_GENERIC_M with a collation ID of 10001. The GENERIC_M linguistic sort is used as the basis for the new linguistic sort. Figure 13-26 shows how to begin.

Figure 13-26 General Tab Page for Collation

Description of "Figure 13-26 General Tab Page for Collation"

Settings for the flags are automatically derived. SWAP_WITH_NEXT is relevant for Thai and Lao sorts. REVERSE_SECONDARY is for French sorts. CANONICAL_EQUIVALENCE determines whether canonical rules are used. In this example, CANONICAL_EQUIVALENCE is checked.

The valid range for Collation ID (sort ID) for a user-defined sort is 1000 to 2000 for monolingual collation and 10000 to 11000 for multilingual collation.

Figure 13-27 shows the Unicode Collation Sequence tab page.

Figure 13-27 Unicode Collation Sequence Tab Page

Description of "Figure 13-27 Unicode Collation Sequence Tab Page"

This example customizes the linguistic sort by moving digits so that they sort after letters. Complete the following steps:

1. Highlight the Unicode value that you want to move. In Figure 13-27, the \x0034 Unicode value is highlighted. Its location in the Unicode Collation Sequence is called a node.

2. Click Cut. Select the location where you want to move the node.

3. Click Paste. Clicking Paste opens the Paste Node dialog box, shown in Figure 13-28.

Figure 13-28 Paste Node Dialog Box

Description of "Figure 13-28 Paste Node Dialog Box"

• The Paste Node dialog box enables you to choose whether to paste the node after or before the location you have selected. It also enables you to choose the level (Primary, Secondary, or Tertiary) of the node in relation to the node that you want to paste it next to.

  Select the position and the level at which you want to paste the node.

  In Figure 13-28, the After button and the Primary button are selected.

• Click OK to paste the node.

  Use similar steps to move other digits to a position after the letters a through z.

Figure 13-29 shows the resulting Unicode Collation Sequence tab page after the digits 0 through 4 have been moved to a position after the letters a through z.

The rest of this section contains the following topics:

• Changing the Sort Order for All Characters with the Same Diacritic

• Changing the Sort Order for One Character with a Diacritic

Changing the Sort Order for All Characters with the Same Diacritic

This example shows how to change the sort order for characters with diacritics. You can do this by changing the sort for all characters containing a particular diacritic or by changing one character at a time. This example changes the sort of each character with a circumflex (for example, û) to be after the same character containing a tilde.

Verify the current sort order by choosing Tools > Canonical Rules. This opens the Canonical Rules dialog box, shown in Figure 13-30.

Figure 13-30 Canonical Rules Dialog Box

Description of "Figure 13-30 Canonical Rules Dialog Box"

Figure 13-30 shows how characters are decomposed into their canonical equivalents and their current sorting orders. For example, û is represented as u plus ^.

See Also:

Chapter 5, "Linguistic Sorting and String Searching" for more information about canonical rules

In the Oracle Locale Builder collation window (shown in Figure 13-26), click the Non-Spacing Characters tab. If you use the Non-Spacing Characters tab page, then changes for diacritics apply to all characters. Figure 13-31 shows the Non-Spacing Characters tab page.

Figure 13-31 Changing the Sort Order for All Characters with the Same Diacritic

Description of "Figure 13-31 Changing the Sort Order for All Characters with the Same Diacritic"

Select the circumflex and click Cut. Click Yes in the Removal Confirmation dialog box. Select the tilde and click Paste. Choose After and Secondary in the Paste Node dialog box and click OK.

Figure 13-32 illustrates the new sort order.

Figure 13-32 The New Sort Order for Characters with the Same Diacritic

Description of "Figure 13-32 The New Sort Order for Characters with the Same Diacritic"

Changing the Sort Order for One Character with a Diacritic

To change the order of a specific character with a diacritic, insert the character directly into the appropriate position. Characters with diacritics do not appear in the Unicode Collation Sequence tab page, so you cannot cut and paste them into the new location.

This example changes the sort order for ä so that it sorts after Z.

Select the Unicode Collation tab. Highlight the character, Z, that you want to put ä next to. Click Add. The Insert New Node dialog box appears, as shown in Figure 13-33.

Figure 13-33 Changing the Sort Order of One Character with a Diacritic

Description of "Figure 13-33 Changing the Sort Order of One Character with a Diacritic"

Choose After and Primary in the Insert New Node dialog box. Enter the Unicode code point value of ä. The code point value is \x00e4. Click OK.

Figure 13-34 shows the resulting sort order.

Description of "Figure 13-34 New Sort Order After Changing a Single Character"

Generating and Installing NLB Files

After you have defined a new language, territory, character set, or linguistic sort, generate new NLB files from the NLT files as follows.

1. As the user who owns the files (typically user oracle), back up the NLS installation boot file (lx0boot.nlb) and the NLS system boot file (lx1boot.nlb) in the ORA_NLS10 directory. On a UNIX platform, enter commands similar to the following example:

   % setenv ORA_NLS10 $ORACLE_HOME/nls/data
   % cd $ORA_NLS10
   % cp -p lx0boot.nlb lx0boot.nlb.orig
   % cp -p lx1boot.nlb lx1boot.nlb.orig
   

   Note that the -p option preserves the timestamp of the original file.

2. In Oracle Locale Builder, choose Tools > Generate NLB or click the Generate NLB icon in the left side bar.

3. Click Browse to find the directory where the NLT file is located. The location dialog box is shown in Figure 13-35.

   Figure 13-35 Location Dialog Box

   
   Description of "Figure 13-35 Location Dialog Box"
   
   

   Do not try to specify an NLT file. Oracle Locale Builder generates an NLB file for each NLT file.

4. Click OK to generate the NLB files.

   Figure 13-36 illustrates the final notification that you have successfully generated NLB files for all NLT files in the directory.

   Figure 13-36 NLB Generation Success Dialog Box

   
   Description of "Figure 13-36 NLB Generation Success Dialog Box"
   
   

5. Copy the lx1boot.nlb file into the path that is specified by the ORA_NLS10 environment variable. For example, on a UNIX platform, enter a command similar to the following example:

   % cp /directory_name/lx1boot.nlb $ORA_NLS10/lx1boot.nlb
   

6. Copy the new NLB files into the ORA_NLS10 directory. For example, on a UNIX platform, enter commands similar to the following example:

   % cp /directory_name/lx22710.nlb $ORA_NLS10
   % cp /directory_name/lx52710.nlb $ORA_NLS10
   

   Note:

   Oracle Locale Builder generates NLB files in the directory where the NLT files reside, which is typically ../nlsrtl3/admin/data.

7. Restart the database to use the newly created locale data.

8. To use the new locale data on the client side, exit the client and re-invoke the client after installing the NLB files.

   See Also:

   "Locale Data on Demand" for more information about the ORA_NLS10 environment variable

Deploying Custom NLB Files on Other Platforms

When deploying your locale customization files on other Oracle Database installations, running with the same Oracle Database release, and under the same operating system platform, you will need to copy all the custom NLB files together with the lx1boot.nlb file over to the target machine. In order to deploy the custom NLB files on a different platform, you will need to copy over the custom .NLT files to your new platform, and then repeat the NLB generation and installation steps as described in the section "Generating and Installing NLB Files".

Upgrading Custom NLB Files from Previous Releases of Oracle Database

Locale definition files are database release-dependent. For example, NLB files from Oracle Database 9i and Oracle Database 10g are not directly supported in an Oracle Database 11g Release 1 installation, and so forth. In order to migrate your locale customization files from a previous release of the database to your current release, you first need to convert the files into the latest NLT format. This is achieved by loading the locale customization files (either NLB or NLT), and saving them individually into NLT files using the current version of the Oracle Locale Builder. Next, you need to repeat the NLB generation and installation steps as described in the section "Generating and Installing NLB Files".

Please note that Oracle Locale Builder can read and process previous versions of the NLT and NLB files, as well as read and process these files from different platforms. However, Oracle Locale Builder always saves NLT files and generates NLB files in the latest format for the release of Oracle Database that you have installed.

Transporting NLB Data from One Platform to Another

NLB files that are generated on one platform can be transported to another platform by FTP or other copy utilities. The transported NLB files can be used the same way as the NLB files that were generated on the original platform. For example, NLB files that are generated on a Solaris platform can be copied by FTP to a Windows platform and will provide the same functionality there. This is convenient because locale data can be modified on one platform and copied to other platforms. Note that you must copy all of the NLB files from one platform to another, not just the files that have been modified. Also note that "Generating and Installing NLB Files" described is performed the same way as in previous releases.

Different binary formats (such as 32-bit, 64-bit, big-endian, little-endian, ASCII, and EBCDIC) are processed transparently during NLB loading.

Adding Custom Locale Definitions to Java Components with the GINSTALL Utility

The ginstall utility adds custom character sets, language, territory, and linguistic sorts to Java components in your applications. You use Locale Builder to define your custom character sets, language, territory, and linguistic sort. Locale Builder generates NLT files, which contain the custom definitions. Then to add the custom definitions to the Java components, you run ginstall to generate gdk_custom.jar. The same procedures can be used for Oracle Database release 10.2 and 10.1, as well as release 11.1.

To add custom definitions for character set, language, territory, and linguistic sort:

1. Generate the NLT file using Oracle Locale Builder.

   • If you are upgrading custom NLB files from a previous release, follow the procedure described in Upgrading Custom NLB Files from Previous Releases of Oracle Database.

2. Run ginstall with -add or -a option to generate gdk_custom.jar.

   ginstall –[add | a] lx2dddd.nlt
   

   • To generate multiple NLT files:

     ginstall -[add | a] lx2dddd.nlt  lx2dddd.nlt  lx2dddd.nlt
     

3. Copy gdk_custom.jar to the same directory as orai18n.jar or orai18n-mapping.jar.

To remove a custom definition:

• Run ginstall as follows.

  ginstall –[remove | r] <path to gdk_custom.jar> <name of NLT file>
  

To update a custom definition:

• Run ginstall as follows.

  ginstall –[update | u] <path to gdk_custom.jar> <name of NLT file>
