本例涉及两个站点.
主体定义站点:AVATAR.COOLYOUNG.COM.CN
主体站点:AUTHAA.COOLYOUNG.COM.CN
注:主体定义站点指配置复制工作的站点
本例涉及的用户.
复制管理员:repadmin
应用用户:hawa
本例复制的对象:hw_test 数据表
1.在主体定义站点复制用户下创建复制对象 SQL> select * from global_name;
GLOBAL_NAME
-----------------------------------------------------------
AVATAR.COOLYOUNG.COM.CN
SQL> connect hawa/password
Connected.
SQL> create table hw_test as select * from hw_online;
Table created.
SQL> select count(*) from hw_test;
COUNT(*)
----------
464
SQL> alter table hw_test add (constraint pk_userid primary key (numuserid));
Table altered.
2.在主体站点同样创建复制对象 SQL> select * from global_name;
GLOBAL_NAME
------------------------------------------------------------------------
AUTHAA.COOLYOUNG.COM.CN
SQL> connect hawa/password
Connected.
SQL> create table hw_test as select * from hw_online;
Table created.
SQL> select count(*) from hw_test;
COUNT(*)
----------
0
3.在主体站点手工同步数据 SQL> connect repadmin/password
Connected.
SQL> insert into hawa.hw_test select * from hawa.hw_test@avatar;
464 rows created.
SQL> commit;
Commit complete.
4.在主体定义站点开始操作 登陆主体定义站点
