PL/SQL :: Illegal Use Of LONG Datatype

I've this problem:

create table t1 ( x long );
Table created.

create table t2 ( x long );
Table created.

insert into t1 values ( 'test long type' );
1 row created.

insert into t2 select * from t1;
                      *
ERROR at line 1:
ORA-00997: illegal use of LONG datatype

How can I issue this error, I need use also dblink with long type.

I do not want to use the copy command.

I know that you can solve this problem with a stored procedure or anonymous block.
