Oracle Transparent Gateway on Solaris

I had Oracle 12c Enterprise on Windows 64 and MariaDB 10.2 on Ubuntu . I have been using ODBC transparent gateway to send the data from Oracle to MariaDB.

I am in the process of transitioning to Oracle Enterprise 19c on Solaris and MariaDB 10.4 on RHEL8 .It looks like , there are no native mariadb odbc drivers for Solaris.

What is your recommendation on connecting Maria DB ( RHEL) to Oracle 19 ( Solaris ) ?
With the current licensing model , only the ODBC Transparent Gateway covered with regular licensing?

This data transfer happens once a day ( via dbms_scheduler). At the maximum , we will have 2000 records transferred between these DBMSes.

What is the best approach ?
Any known issues with Oracle Solaris TG ?

Thanks very much.
