SQL & PL/SQL :: Invoke Procedure With DML And COMMIT Through DBLINK?

A simple procedure is created as follows:

Create procedure p1(a varhar2, b varchar2, c_err out varchar2) is
begin
insert into t1 values(a,b);
commit;
exception
when others then
c_err:= substr(sqlerrm,1,250);
end;

It is executed fine.But if it is executed from a dblink as

declare
c varchar2(200);
begin
t1@remote_link('testa','testb',c);
dbms_output.put_line(c);
end;

It is giving error "ORA-02064: distributed operation not supported". How can I pass DML through this procedure and commit from a dblink?
