Creating Rules Files
If you require rules that are not in the delivered rules files, you can add custom rules files. Oracle recommends that you clone an existing rules file. In this way, you can match key elements (rule set, database, database version, definition type, and so on) and then supply your own SQL code or Java program.
Make sure that you save your rules file with a new name and move it to a position above the existing rules file.
If you want to override a specific rule using your own rules file, make sure you
Use the same pillar as in the rule for which you want to override.
In the Select dialog (Configure, Rules Files), place the rules file that contains your new rule above the rules file to be overridden in the rules file list.
