About Siebel Multilingual Deployments
Upgrades: All Siebel upgrades.
Environments: Development, production test, production.
Databases: All databases.
The upgrep process imports repository strings and seed data in only the primary language. The primary language, also called the base language, is the language in which data is stored in the Siebel Database.
If you have multilingual deployments, you must import multilingual repository strings and seed data after performing the upgrep. This applies to development, production test, and production upgrades.
See Technical Note 447 on Oracle's Siebel SupportWeb for instructions on how to perform these imports.
See the Siebel Installation Guide for the operating system you are using for instructions on installing and configuring multiple language packs.
For a list of supported code pages and encoding strategies, see System Requirements and Supported Platforms on Siebel SupportWeb.
In a Unicode-enabled database environment, you can install any available language pack. In a non-Unicode database environment, you must consider the correlation of the language packs you want to install and the characters supported by your RDBMS code page. For example, in a Western European code page RDBMS, you can only install Western European language packs such as English, French, Spanish, or German. In a Japanese code page RDBMS, you can only install Japanese or English language packs.
