About Unicode Conversion Tables
Siebel eBusiness Applications, Version 7.5 introduced Unicode character set support. However, Siebel Systems does not support Unicode on DB2 for z/OS. As a result, if the Siebel Unicode-enabled application server is to communicate properly with the DB2 for z/OS database, you must install Unicode Conversion Services. Conversion errors can result if the z/Series Unicode Conversion Services images do not include the required conversion tables.
You must configure the z/Series Unicode Conversion Services with the conversions required by the codepages specific to your DB2 subsystem. Because of the difficulty in determining all the conversions required for the conversion image, it is recommended that you use the prebuilt image provided on z/OS V1.R2 and later, as provided by the IBM APAR OA04069. This preloads a Unicode conversion image with many tables which support a substantial number of codepage conversions.
