Starting with DB2 V9.7 Fix Pack 1, code page 1392 (GB18030) is supported as a client and database code page. Prior to this release, code page 1392 could only be used with the EXPORT, IMPORT, and LOAD utilities with a Unicode database.
CREATE DATABASE ... USING CODESET GB18030 TERRITORY CN
You can connect to databases with GB18030 data from clients that either use code page 1392 or Unicode code page 1208 as the application code page.
File names with characters in the GB18030 code set but not in the GBK code set are not supported in the deprecated Control Center. To open or save these files, use CLP commands or CLI.
