Hi everyone,

I have to setup Oracle Database link from Oracle 10g DB on AIX v5.3 to a MySQL v5.7.33 Community Server Edition instance on RHEL 7.7 using unixODBC and MySQL Connector/ODBC v5.1.8.

Oracle DB is 10g running on AIX where I have unixODBC v2.3.0 and MySQL v5.1.8 installed as per Oracle note (and since that is the last available unixODBC and MySQL connector compiled package for AIX 5.3 64-bit)

I got the Oracle database link working. I am able to connect from within Oracle database sqlplus via database link to the Mysql db, but I am only able to query numeric and number like (datetime) columns, not the character data.

Oracle DB character set is AL32UTF8
MySQL DB character set is utf8

ERROR at line 1:

ORA-28500: connection from ORACLE to a non-Oracle system returned this message:

[unixODBC][MySQL][ODBC 5.1 Driver]Can't initialize character set utf8mb4 (path:

/usr/local/mysql/share/charsets/) {HY000,NativeErr = 2019}

ORA-02063: preceding 2 lines from DEFAULT_ALERTNOTIFICATION


On my Oracle DB server with unixODBC and MySQL connector/ODBC, I found that /usr/local/mysql directory doesn't have any files for character sets.
Would any one know what did I not install correctly?

If I need to compile a package, what package can help me bring the required files in /usr/local/mysql?

Tried following in my odbc.ini DSN entry, but can't get character data queried.
