About Adding a Language to an Existing Database
Adding a language to an existing Siebel database installs seed data to support that language. After the database is initially installed with the primary language, each additional language must be installed separately using an add-language operation. This topic is part of About Installing the Siebel Database.
To add a new language to previously installed Siebel CRM, you must have installed its Siebel language on the installed Siebel Server, using the Siebel CRM installer. See also Installing and Deploying Siebel CRM with Multiple Languages.
After adding a language, you must import the Siebel Repository for this language. For more information, see Importing a Siebel Repository Manually into the Siebel Database.
After you have added a language to the Siebel database, your seed data is multilingual. You must enable the multilingual list of values (MLOV) capability for Siebel CRM, and you must enable individual LOVs associated with the language. For more information, see:
