You need to activate the driver even for the trial version.
If you need to perform an offline activation or prefer not to activate the driver over the internet, you can use a file containing the activation key.
This method works only for Perpetual licenses.
To activate the driver offline on Linux, follow these steps:
/usr/share/devart/odbcmysql/usr/local/devart/odbcmysqlactivation.key name.
The driver gets activated.
