You can utilize this parameter to implement tighter security for your PL/SQL application by blocking package and procedure calls which should not be allowed to run from the DAD. Oracle recommends a DAD configuration for Oracle Application Express which utilizes the <code>PlsqlRequestValidationFunction</code> directive with a value of <code>wwv_flow_epg_include_modules.authorize</code>.</p> <p>The purpose of the <code>PlsqlRequestValidationFunction</code> parameter is to control which procedures can be invoked through <code>mod_plsql</code>. By default, the only procedures permitted are the public entry points of Oracle Application Express. This can be extended using the validation functions shipped with Oracle Application Express.
