DBMS_TSDP_PROTECT 添加FGA策略时报错

[夜未眠风已息]

--创建敏感类型
BEGIN
 DBMS_TSDP_MANAGE.ADD_SENSITIVE_TYPE (
  sensitive_type  => 'cn_type',
  user_comment    => 'Test data type');
END;

--添加敏感类型与数据列关联
--schema_name,table_name,columm_name默认为‘%’
BEGIN
 DBMS_TSDP_MANAGE.ADD_SENSITIVE_COLUMN(
   schema_name        => 'DBSEC',
   table_name         => 'T2',
   column_name        => 'CN',
   sensitive_type     => 'cn_type',
   user_comment       => 'Sensitive column addition of cn_type');
END;

--添加策略
DECLARE
  redact_feature_options DBMS_TSDP_PROTECT.FEATURE_OPTIONS;
  policy_conditions DBMS_TSDP_PROTECT.POLICY_CONDITIONS;
BEGIN
  redact_feature_options ('object_schema') := 'DBSEC';
  redact_feature_options ('object_name') := 'T2';
  redact_feature_options ('statement_types') := 'SELECT';
  redact_feature_options ('policy_name') := 'FGA_TEST';
  DBMS_TSDP_PROTECT.ADD_POLICY ( 'FGAAA_CN', DBMS_TSDP_PROTECT.FGA, redact_feature_options,policy_conditions);
END;

DBMS_TSDP_PROTECT.ADD_POLICY这句报错
ORA-45635: 找到无效的参数: ORA-06550: 第 1 行, 第 7 列:

直接使用DBMS_FGA.ADD_POLICY 是能成功的

begin
DBMS_FGA.ADD_POLICY (
   object_schema      =>  'DBSEC', 
   object_name        =>  'T2', 
   policy_name        =>  'mypolicy1', 
   statement_types    =>  'SELECT'
   ); 
end;
