Hi
Following is our environment
DB Version: Oracle 11g R2 (11.2.0.3.0) 64bit
OS : OEL 5U2
Characterset: AMERICAN_AMERICA.AR8MSWIN1256
We have an opensource application built on php. CHARSET was defined as AR8MSWIN1256 in the configuration file. Data was inserted using browser based interface. Use access the system using IE 8 since it is web based application. Data comprise of both Arabic and English. It is displayed perfectly fine using browser ie Arabic shows proper Arabic characters and English shows correct English.
Problem started when a requirement came to generate some reports using Oracle Reports 10g. Arabic data show as garbage in the reports. Vendor was asked to provide some solution. They suggested to change the CHARSET to AL32UTF8 in the config file of the application. After making the changes, the new data that is inserted in the database can be seen correctly for both languages regardless of the tool (be it SQLDeveloper or Oracle Reports). The old data, however, shows garbage. Surprisingly when data is extracted using scripts in flat files and then imported in the test database after setting environment variable NLS_LANG=AMERICAN_AMERICA.UTF8 using @/../filename.sql, it converts it properly. Since data is huge and this is taking way too much time, I was hoping if someone could help me in quickly perform this migration? Already tried CSSCAN/CSALTER and DMU but did not succeed. DMU stopped at 5th stage when it was supposed to issue ALTER DATABASE CHARACTER SET command.
Currently I am installing database with AL32UTF8 characterset and planning to import the schema in it. Is my approach correct? Any help will be highly appreciated.
Thank you
