Oracle高级复制的创建配置步骤-Step by Step

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
本例的先决条件:你需要设置好相应的参数,job_queue_processes需要大于0,global_name=true,并且建立相应的db link.
这些具体可以参考:高级复制的初步研究一文.

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
$ sqlplus repadmin/password

SQL*Plus: Release 9.2.0.4.0 - Production on Mon Jun 27 09:32:36 2005

Oracle9i Enterprise Edition Release 9.2.0.4.0 - 64bit Production
With the Partitioning, OLAP and Oracle Data Mining options
JServer Release 9.2.0.4.0 - Production

SQL> select * from global_name;

GLOBAL_NAME
----------------------------------------------------------------------------
AVATAR.COOLYOUNG.COM.CN
 

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';

GNAME                          M STATUS
------------------------------ - ---------
REP_HH                         Y QUIESCED

 

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';

SNAME                          ONAME                          STATUS     GNAME
------------------------------ ------------------------------ ---------- ------------------------------
HAWA                           HW_TEST                        VALID      REP_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';

GNAME                          M STATUS
------------------------------ - ---------
REP_HH                         Y QUIESCED

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

SNAME                          ONAME                          STATUS     GNAME
------------------------------ ------------------------------ ---------- ------------------------------
HAWA                           HW_TEST                        VALID      REP_HH
HAWA                           HW_TEST$RP                     VALID      REP_HH
HAWA                           HW_TEST$RP                     VALID      REP_HH

SQL>

 

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';

GNAME        DBLINK                    MASTERDEF  MASTER
------------ ------------------------- ---------- ----------
REP_HH       AVATAR.COOLYOUNG.COM.CN   Y          Y
REP_HH       AUTHAA.COOLYOUNG.COM.CN   N          Y
 

登陆主体站点，检查复制对象情况:
[oracle@www167 oracle]$ sqlplus repadmin/password

SQL> select * from global_name;

GLOBAL_NAME
--------------------------------------------------------------------------------
AUTHAA.COOLYOUNG.COM.CN

SQL> set linesize 120
SQL> select sname,oname,status,gname from dba_repobject where gname='REP_HH';

SNAME                          ONAME                          STATUS     GNAME

在主体定义站点启动复制:
SQL> select * from global_name;

GLOBAL_NAME
-----------------------------------------------------------------------------
AVATAR.COOLYOUNG.COM.CN

SQL> execute dbms_repcat.resume_master_activity('rep_hh',true);

PL/SQL procedure successfully completed.

 

在主体定义站点删除数据测试:
SQL> connect hawa/password
Connected.
SQL> select count(*) from hw_test;

  COUNT(*)
----------
       464

SQL> delete from hw_test where rownum <20;

19 rows deleted.

SQL> commit;

Commit complete.

SQL> select count(*) from hw_test;

  COUNT(*)
----------
       445
 

在主体站点观察变化:
SQL> select * from global_name;

GLOBAL_NAME
--------------------------------------------------------------------------------
AUTHAA.COOLYOUNG.COM.CN

SQL> select count(*) from hw_test;

  COUNT(*)
----------
       445

SQL>    
 

至此，同步复制配置完毕。
