Workarounds and Mitigations

On Linux and Unix systems, if you are not using Federation wrappers, you can remove the presto-jdbc jar file.

You can check if the jar file can be safely removed by running

SELECT SETTING FROM SYSIBM.SYSSERVEROPTIONS WHERE OPTION = ‘DRIVER_PACKAGE’;

If the presto-jdbc jar file is not listed in the result, you can remove the file.
