Upgrade Planning for Siebel Unicode Support

Environments: Development, Test and Production.

For Western European languages and Japanese, Siebel Business Applications support both non-Unicode and Unicode code pages. For all other supported languages, Siebel Business Applications support only Unicode code pages.

Unicode is recommended if your installation uses Siebel Email Response, correspondence, or similar functionality, particularly if content is generated on a separate system.

This is because Siebel Business Applications use Unicode internally. If the RDBMS is not using Unicode, then Siebel Business Applications convert content from Unicode to the database code page. Using a Unicode code page for the database prevents string conversion problems on text content.

Before converting to Unicode, your encryption method must be AES.

Caution: Migrating to Unicode is more complex than simply importing your existing data into a Unicode database. Failure to execute the migration correctly can result in serious data corruption or unrecoverable data loss. For this reason, Oracle’s Advanced Customer Services participation is mandatory. To perform a Unicode migration, contact your Oracle sales representative for Oracle Advanced Customer Services to request assistance from Oracle’s Application Expert Services.
