How client applications use locales.dat

Client applications use the locales.dat file to identify the language and character set to use. The connection process follows these steps:

1. When a client application starts, it checks the operating system locale setting and then checks the locales.dat file to see if that setting is appropriate for Adaptive Server. For example, a locale entry for French can look like the following:

   locale = fr_FR, french, iso_1
   

2. When the client connects to Adaptive Server, the language and character set information is passed to Adaptive Server in the login record.

3. Adaptive Server then uses:

   • The character set information, for example, iso_1, to identify the client’s character set and verify whether it can convert character data to this character set

   • The language (in the preceding example, French) and character set information to see if it has messages in the client’s language
