The HCL OneDB registry file (Windows)

The Code-Set Name-Mapping file, which is called registry, is an ASCII file that associates code-set names and aliases with their code-set numbers.

A code-set number is based on the HCL CCSID numbering scheme. HCL OneDB™ products use code-set numbers to determine the file names of locale and code-set-conversion files.

For example, you can specify the French locale that supports the ISO8859-1 code set with any of the following locale names as locale aliases:

For example, you can specify a locale with any of the following locale aliases:

The full code-set name
```
fr_fr.8859-1
```
The decimal value of the HCL CCSID number
```
fr_fr.819
```
The hexadecimal value of the HCL CCSID number
```
fr_fr.0333
```

When you specify a locale name with either of the first two forms, HCL OneDB products use the Code-Set Name-Mapping file to translate between code-set names (8859-1) or code-set number (819) to the condensed code-set name (0333). For information about the file format and search algorithm that HCL OneDB products use to convert code-set names to code-set numbers, see the comments at the top of the registry file.

When the HCL OneDB product needs to obtain information about locale aliases, it accesses the GLS code-set files in the following path:

%ONEDB_HOME%\gls\cmZ\registry

In these paths, ONEDB_HOME is the environment variable that specifies the directory in which you install the HCL OneDB product, gls is the subdirectory that contains the GLS files, and Z represents the version number for the code-set object-file format.

Restriction: Do not remove the Code-Set Name-Mapping file, registry, from the HCL OneDB directory. Do not modify this file. HCL OneDB products use this file for the language processing of all locales.
