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.

复制治理员: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.

SQLselect 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(*)

----------

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

$ sqlplus repadmin/password

创建复制组:

SQL execute dbms_repcat.create_master_repgroup('rep_hh');

PL/SQL procedure successfully completed.

SQL select gname,master,status from dba_repgroup where gname='REP_HH';

GNAMEM STATUS

在复制组里加入复制对象

SQL execute dbms_repcat.create_master_repobject

(sname='hawa',oname='hw_test',

type='table',use_existing_object=true,gname='rep_hh',copy_rows=false);

PL/SQL procedure successfully completed.

SQL select sname,oname,status,gname from dba_repobject where gname='REP_HH';

SNAMEONAMESTATUS GNAME

------------------------------ ------------------------------ ---------- ------------------------------

HAWA HW_TESTVALIDREP_HH

对复制对象产生复制支持

SQL execute dbms_repcat.generate_replication_support('hawa','hw_test','table');

PL/SQL procedure successfully completed.

SQL select gname, master, status from dba_repgroup where gname='REP_HH';

GNAMEM STATUS

------------------------------ - ---------

REP_HH Y QUIESCED

SQL select sname,oname,status,gname from dba_repobject where gname='REP_HH';

添加主体复制节点

SQL execute dbms_repcat.add_master_database

(gname='rep_hh',master='AUTHAA.COOLYOUNG.COM.CN',use_existing_objects=true,

copy_rows=false, propagation_mode = 'synchronous');

PL/SQL procedure successfully completed.

SQL column masterdef format a10

SQL column master format a10

SQL column dblink format a25

SQL column gname format a12

SQL select gname, dblink, masterdef MASTERDEF, master MASTER from sys.dba_repsites where gname='REP_HH';
