高级复制之主站点与物化视图站点之间的数据复制（基于物化视图的配置方式）

基于版本10g（10.2.0.1）的高级复制－基于物化视图的配置方式

官方文档参考：http://docs.oracle.com/cd/E11882_01/server.112/e10707/rarrepsite.htm#REPMA002

主站点global_name:
SQL> select * from global_name;
GLOBAL_NAME
--------------------------------------------------------------------------------
DSOURCE.REGRESS.RDBMS.DEV.US.ORACLE.COM


物化视图站点global_name:
SQL> select * from global_name;
GLOBAL_NAME
--------------------------------------------------------------------------------
DTARGET.REGRESS.RDBMS.DEV.US.ORACLE.COM


1.主站点配置：
    1)创建复制管理用户，并授予权限：
conn system/oracle
CREATE USER repadmin IDENTIFIED BY repadmin;
exec DBMS_REPCAT_ADMIN.GRANT_ADMIN_ANY_SCHEMA(username=>'repadmin');
GRANT COMMENT ANY TABLE TO repadmin;
GRANT LOCK ANY TABLE TO repadmin;
GRANT SELECT ANY DICTIONARY TO repadmin;
2)注册propagator：
exec DBMS_DEFER_SYS.REGISTER_PROPAGATOR(username=>'repadmin');
      注：如果出现ORA-23394: duplicate propagator错误，说明之前注册过，处理方法如下：
     a.查询注册信息：select * from system.def$_propagator;
     b.注销原来的注册信息：exec DBMS_DEFER_SYS.UNREGISTER_PROPAGATOR(username=>'apadmin');
3)注册receiver:
BEGIN
  DBMS_REPCAT_ADMIN.REGISTER_USER_REPGROUP (
  username => 'repadmin',
  privilege_type => 'receiver',
  list_of_gnames => NULL);
END;
/
4)Schedule purge:
CONNECT repadmin/repadmin
BEGIN
   DBMS_DEFER_SYS.SCHEDULE_PURGE (
   next_date => SYSDATE,
   interval => 'SYSDATE + 1/1440',
   delay_seconds => 0);
END;
/  
5)创建主站点代理管理用户，并注册相关权限:
CONNECT system/oracle
CREATE USER proxy_mviewadmin IDENTIFIED BY proxy_mviewadmin; 
BEGIN
   DBMS_REPCAT_ADMIN.REGISTER_USER_REPGROUP (
   username => 'proxy_mviewadmin',
   privilege_type => 'proxy_snapadmin',
   list_of_gnames => NULL);
END;
/
GRANT SELECT_CATALOG_ROLE TO proxy_mviewadmin;  
6)创建主站点代理刷新用户，并注册相关权限: 
CREATE USER proxy_refresher IDENTIFIED BY proxy_refresher;
GRANT CREATE SESSION TO proxy_refresher;
GRANT SELECT ANY TABLE TO proxy_refresher;
  7)创建测试用户及测试表:
CREATE USER mv IDENTIFIED BY mv;
grant dba to mv;
GRANT
CREATE SESSION,
CREATE TABLE,
CREATE PROCEDURE,
CREATE SEQUENCE,
CREATE TRIGGER,
CREATE VIEW,
CREATE SYNONYM,
ALTER SESSION,
CREATE MATERIALIZED VIEW,
ALTER ANY MATERIALIZED VIEW,
CREATE DATABASE LINK
TO mv;
conn mv/mv
create table t(id number primary key);
    8)创建物化视图日志：
conn mv/mv
CREATE MATERIALIZED VIEW LOG ON mv.t;
  9)创建主组:
CONNECT repadmin/repadmin
BEGIN
   DBMS_REPCAT.CREATE_MASTER_REPGROUP (
      gname => 'mv_repg');
END;
/
  10)添加对象到主组:
BEGIN
   DBMS_REPCAT.CREATE_MASTER_REPOBJECT (
      gname => 'mv_repg',
      type => 'TABLE',
      oname => 't',
      sname => 'mv',
      use_existing_object => TRUE,
      copy_rows => FALSE);
END;
/
  11)生成复制支持:
BEGIN 
    DBMS_REPCAT.GENERATE_REPLICATION_SUPPORT (
      sname => 'mv',
      oname => 't', 
      type => 'TABLE',
      min_communication => TRUE); 
END;
/
  12)开始复制:
BEGIN 
   DBMS_REPCAT.RESUME_MASTER_ACTIVITY (
      gname => 'mv_repg'); 
END;
/
       查询主组状态：
SQL> select gname,master,status from dba_repgroup where gname='MV_REPG';


GNAME                          M STATUS
------------------------------ - ---------
MV_REPG                        Y NORMAL


 
2.物化视图站点配置：  
    1)创建物化视图站点管理用户，并授予相关权限：
conn system/oracle
CREATE USER mviewadmin IDENTIFIED BY mviewadmin;
BEGIN
   DBMS_REPCAT_ADMIN.GRANT_ADMIN_ANY_SCHEMA (
      username => 'mviewadmin');
END;
/
GRANT COMMENT ANY TABLE TO mviewadmin;
GRANT LOCK ANY TABLE TO mviewadmin;
GRANT SELECT ANY DICTIONARY TO mviewadmin;
    2)创建传输用户，并授予相关权限：
CREATE USER propagator IDENTIFIED BY propagator;
BEGIN
   DBMS_DEFER_SYS.REGISTER_PROPAGATOR (
      username => 'propagator');
END;
/
      注：如果出现ORA-23394: duplicate propagator错误，说明之前注册过，处理方法如下：
     a.查询注册信息：select * from system.def$_propagator;
     b.注销原来的注册信息：exec DBMS_DEFER_SYS.UNREGISTER_PROPAGATOR(username=>'apadmin');
    3)创建刷新用户，并授予相关权限：
CREATE USER refresher IDENTIFIED BY refresher;
GRANT CREATE SESSION TO refresher;
GRANT ALTER ANY MATERIALIZED VIEW TO refresher;
    4)注册reciver:
BEGIN
   DBMS_REPCAT_ADMIN.REGISTER_USER_REPGROUP (
      username => 'mviewadmin',
      privilege_type => 'receiver',
      list_of_gnames => NULL);
END;
/
    5)创建到主站点的public db link:
conn system/oracle
CREATE PUBLIC DATABASE LINK DSOURCE.REGRESS.RDBMS.DEV.US.ORACLE.COM USING 'DSOURCE';
    6)使用物化视图管理用户创建到主站点的db link:
conn mviewadmin/mviewadmin
CREATE DATABASE LINK DSOURCE.REGRESS.RDBMS.DEV.US.ORACLE.COM 
CONNECT TO proxy_mviewadmin IDENTIFIED BY proxy_mviewadmin;
    7)创建propagator/receiver db link:
CONNECT propagator/propagator
CREATE DATABASE LINK DSOURCE.REGRESS.RDBMS.DEV.US.ORACLE.COM 
CONNECT TO repadmin IDENTIFIED BY repadmin;
    8)Schedule purge：
CONNECT mviewadmin/mviewadmin
BEGIN
   DBMS_DEFER_SYS.SCHEDULE_PURGE (
   next_date => SYSDATE,
   interval => 'SYSDATE + 1/1440',
   delay_seconds => 0,
   rollback_segment => '');
END;
/
    9)Schedule push
BEGIN
   DBMS_DEFER_SYS.SCHEDULE_PUSH (
      destination => 'DSOURCE.REGRESS.RDBMS.DEV.US.ORACLE.COM',
      interval => 'SYSDATE + 1/1440',
      next_date => SYSDATE,
      stop_on_error => FALSE,
      delay_seconds => 0,
      parallelism => 0);
END;
/
    10)创建代理用户，并授予相关权限:
CONNECT system/oracle
CREATE USER proxy_mviewadmin IDENTIFIED BY proxy_mviewadmin;
BEGIN
   DBMS_REPCAT_ADMIN.REGISTER_USER_REPGROUP (
      username => 'proxy_mviewadmin',
      privilege_type => 'proxy_snapadmin',
      list_of_gnames => NULL);
END;
/
GRANT SELECT_CATALOG_ROLE TO proxy_mviewadmin;
    11)创建代理刷新用户，并授予相关权限:
CREATE USER proxy_refresher IDENTIFIED BY proxy_refresher;
GRANT CREATE SESSION TO proxy_refresher;
GRANT SELECT ANY TABLE TO proxy_refresher;
    12)创建测试用户，并授予相关权限：
CREATE USER mv IDENTIFIED BY mv;
grant dba to mv;
GRANT
CREATE SESSION,
CREATE TABLE,
CREATE PROCEDURE,
CREATE SEQUENCE,
CREATE TRIGGER,
CREATE VIEW,
CREATE SYNONYM,
ALTER SESSION,
CREATE MATERIALIZED VIEW,
ALTER ANY MATERIALIZED VIEW,
CREATE DATABASE LINK
TO mv;
13)创建数据库链路：
conn mv/mv
CREATE DATABASE LINK DSOURCE.REGRESS.RDBMS.DEV.US.ORACLE.COM 
CONNECT TO proxy_refresher IDENTIFIED BY proxy_refresher;
14)创建物化视图组：
CONNECT mviewadmin/mviewadmin
BEGIN
   DBMS_REPCAT.CREATE_MVIEW_REPGROUP (
      gname => 'mv_repg',
      master => 'DSOURCE.REGRESS.RDBMS.DEV.US.ORACLE.COM',
      propagation_mode => 'ASYNCHRONOUS');
END;
/
15)创建刷新组：
BEGIN
   DBMS_REFRESH.MAKE (
      name => 'mviewadmin.mv_refresh',
      list => '', 
      next_date => SYSDATE, 
      interval => 'SYSDATE + 1/1440',
      implicit_destroy => FALSE, 
      rollback_seg => '',
      push_deferred_rpc => TRUE, 
      refresh_after_errors => FALSE);
END;
/
16)添加对象到物化视图组：
CREATE MATERIALIZED VIEW mv.t_mv1
REFRESH FAST WITH PRIMARY KEY FOR UPDATE 
AS SELECT * FROM [email protected];


BEGIN
   DBMS_REPCAT.CREATE_MVIEW_REPOBJECT (
      gname => 'mv_repg',
      sname => 'mv',
      oname => 't_mv1',
      type => 'SNAPSHOT',
      min_communication => TRUE);
END;
/
17)添加对象到刷新组：
BEGIN
   DBMS_REFRESH.ADD (
      name => 'mviewadmin.mv_refresh',
      list => 'mv.t_mv1',
      lax => TRUE);
END;
/


3.测试是否配置成功：
1)主站点上使用测试用户mv，向t表中插入数据：
 conn mv/mv
 insert into t values(1);
 commit;
2)物化视图站点使用测试用户mv登录，查询mv.t_mv1物化视图，发现有数据，配置成功：
 SQL> select * from mv.t_mv1;
