OGG单向DDL复制操作

实验目的：在两台虚机模拟实现简单的单向的DDL复制.

说明：因《OGG单机安装与配置,并实验单向DML复制操作》中已配置过单向的dml操作，所以本次配置内容在前一篇的基础之上。

环境解释：在《OGG单机安装与配置,并实验单向DML复制操作》中hostname：slient,db_name:test作为源库，而hostname:one,db_name:onemore作为目标库，本次只需要配置一次反向的操作即可：即slient为源端，  onemo为目标端.

实验步骤：

1.源端关闭回收站
注明：在oracle11g 中， recyclebin参数的 System Modifiable为DEFERRED，意思是要修改系统级的话，就要加deferred参数，对当前已经连接的sesion没有影响，但新连接的session将受到影响。(可以查询视图selectname,isses_modifiable,issys_modifiable from v$parameter wherename='recyclebin';)

SQL> set lines 200
SQL> col name for a30
SQL> select name,isses_modifiable,issys_modifiable from v$parameter where name='recyclebin';

NAME                           ISSES ISSYS_MOD
------------------------------ ----- ---------
recyclebin                     TRUE  DEFERRED

SQL> alter system set recyclebin=off DEFERRED;   

System altered.

SQL> select name,isses_modifiable,issys_modifiable from v$parameter where name='recyclebin';

NAME                           ISSES ISSYS_MOD
------------------------------ ----- ---------
recyclebin                     TRUE  DEFERRED

2.源端配置./GLOBALS（修改全局配置文件添加ggschema参数）
GGSCI (slient as ogg@test) 14> edit params ./GLOBALS  
ggschema ogg
~
"./GLOBALS" [New] 1L, 13C written

GGSCI (slient as ogg@test) 15>

GGSCI (slient as ogg@test) 16> view param ./GLOBALS  

ggschema ogg

GGSCI (slient as ogg@test) 17>

3.源库运行相关的sql脚本
[oracle@slient ogg_home]$ pwd
/opt/ogg/ogg_home
[oracle@slient ogg_home]$
[oracle@slient ogg_home]$ ls mark*
marker_remove.sql  marker_setup.sql  marker_status.sql
[oracle@slient ogg_home]$
[oracle@slient ogg_home]$ sqlplus / as sysdba
