SQL command of Materialized View Relication in Oracle XE

Question

Hi, all,
While waiting for the machine to be OK, I decide to post my understand of materialized view replication here and please point me anything incorrect.
I have two machines A and B, I want to make A as a master and B as replica, to replicate table test.
On A:
create materialized view log on test;
On B:
create database link dbl_a
connect to SYSTEM identified by password
using '(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = a)(PORT = 1521))
(CONNECT_DATA =
(SID = XE)
create materialized view test_mview as select * from test@dbl_a;
At last, when I want to make a synchronization, I run
On B:
EXECUTE DBMS_MVIEW.REFRESH('test_mview');
Any point is appreciated.
Best wishes,
Kemian

You can use DBMS_METADATA :
SCOTT@orcl SQL> create materialized view mv_emp
  2  refresh fast on demand with rowid
  3* as select empno,ename,job,sal from emp
SCOTT@orcl SQL> /
Materialized view created.
SCOTT@orcl SQL> set long 100000
SCOTT@orcl SQL> select DBMS_METADATA.GET_DDL('MATERIALIZED_VIEW','MV_EMP','SCOTT') from dual
SCOTT@orcl SQL> /
DBMS_METADATA.GET_DDL('MATERIALIZED_VIEW','MV_EMP','SCOTT')
  CREATE MATERIALIZED VIEW "SCOTT"."MV_EMP"
