The create table generated for DNA_OPTIONS is
create table DNA_OPTIONS (NAME varchar2(512 char) not null unique, VALUE varchar2(512 char) not null, primary key (NAME))

However, to work correctly in Oracle, it should be:

create table DNA_OPTIONS (NAME varchar2(512 char) not null, VALUE varchar2(512 char) not null, primary key (NAME))

which means we have to remove the unique=true attribute from dna options entity.

There may be another entity like this as well, will double check.
