Database Software

Dear Gurus,

My database is Oracle 11g R2 (11.2.0.1.0) on Sun Solaris 10. To get data from mysql database for reporting purpose, I used DG4ODBC and followed strictly the OMSC note "Detailed Overview of Connecting Oracle to MySQL Using DG4ODBC Database Link [ID 1320645.1]. Here are main configuration steps:
- Check DG4ODBC 32/64-bit
- Install and configure ODBC Driver Manager unixodbc-2.2.14
- Install and configure MyODBC 5.1.8
- Configure tnsnames.ora and listener.ora
- Create db links

Oracle character set is AL32UTF8
MySQL charactoer set is uft8

$ODBC_HOME/etc/odbc.ini

myodbc5 = MyODBC 5.1 Driver DSN

My issue is I can query data from mysql database tables but the output is incorrect in character type columns (VARCHAR columns). It just shows the first character in such columns. I tried to read through some OMSC notes but none is useful. If you experienced on such issues, please share your idea / help me resolve it.

Thanks much in advance,

Hieu
