Languages and Siebel Installations and Upgrades
Installing Siebel languages on the Siebel Server (or on other Siebel components) installs the language-specific run-time environment: resource libraries such as DLL files, configuration (CFG) files, error messages, help files, and so on. In general, you install the same languages on all of the components in your Siebel Enterprise. For more information, see Scenarios for Installing and Deploying Siebel Languages.
When you install the Siebel database for a new installation, language-specific seed data is added for the primary language only. For multilingual deployments, you must add seed data for additional languages separately after your initial Siebel database installation. The Siebel database also includes the Siebel runtime repository.
When you upgrade the Siebel database from a prior Siebel version, all of the existing languages are upgraded at the same time. For more information, see Siebel Database Upgrade Guide.
The languages allowed in data are constrained only by the character encoding of the database platform. For example, although a user might be using a U.S. English version of a Siebel application with a Western European code page database, the user can enter or view contact data in French, because all French characters are representable in the Western European code page.
With a Unicode code page, and appropriate fonts locally installed, languages using dissimilar scripts, such as French and Japanese, can be used together.
