About Unicode Support

Previous releases of Siebel Business Applications supported ASCII- and EBCDIC-based coded character set IDs (CCSIDs) on DB2 for z/OS. Since Siebel CRM 8.0, Unicode is also supported on DB2 for z/OS version 8 and later releases.

Platform, database, and other certifications for Siebel are found on My Oracle Support. For help searching for certifications, see How to Check the Certification Matrix in the New My Oracle Support Site (KB871388).

You can migrate your Siebel database from an EBCDIC or ASCII code page to a Unicode encoding system but this process is not part of the standard Siebel CRM upgrade procedure. A separate migration procedure for migrating to Unicode is performed on the DB2 host after you have upgraded to the current release of Siebel CRM. For information on migrating to Unicode, see Implementing Siebel Business Applications on DB2 for z/OS.

Note: If you are considering migrating your Siebel CRM 8.x z/OS database to Unicode format, be aware that you cannot upgrade to a later release of Siebel CRM using the standard upgrade procedure. If you migrate your Siebel z/OS database to Unicode format, you can upgrade to the latest patchset. However, Oracle will support Unicode database upgrades from one major release of Siebel CRM to another, or incremental Unicode upgrades, in future updates, if required.
