GoldenGate单向复制配置(支持DDL复制)

原创 Linux操作系统 作者:sun642514265 时间:2013-07-29 11:07:53 0 删除 编辑
在上一篇文件中的OGG单向复制配置不支持DLL的同步,只支持DML,因而本文在之前的基础上增加对DDL语句的复制,下面是简要配置过程记录!
一:验证之前的配置不支持DDL复制,这里在source端,新建一张表,发现无法复制到target端!target端也新建相同的表后,DML操作可以成功复制
[root@db1 ~]# su - oracle  
[oracle@db1 ~]$ sqlplus hr/hr  
SQL> create table t2 (id number primary key,name varchar2(20));  
Table created.  
SQL> conn hr/hr@db2  
Connected.  
SQL> select tname from tab where tname='T2';  
no rows selected  
 
SQL> create table t2 (id number primary key,name varchar2(20));  
Table created.  
 
SQL> conn hr/hr  
Connected.  
SQL> insert into t2 values (1,'one');  
1 row created.  
 
SQL> commit;  
Commit complete.  
 
SQL> conn hr/hr@db2  
Connected.  
SQL> select * from t2;  
 
        ID NAME  
---------- --------------------  
         1 one 
二:开始配置OGG支持DDL复制(在source端操作)
1:赋予ogg用户相应的权限,修改全局配置文件添加ggschema参数
SQL> conn /as sysdba  
Connected.  
SQL> grant execute on utl_file to ogg;  
Grant succeeded.  
 
[oracle@db1 ~]$ cd $GGATE   
[oracle@db1 ogg]$ ggsci  
GGSCI (db1) 1> edit param ./GLOBALS  
 
GGSCI (db1) 2> view param ./GLOBALS  
ggschema ogg 
2:运行相关的sql脚本
[oracle@db1 ~]$ cd $GGATE   
[oracle@db1 ogg]$ sqlplus /nolog  
SQL> conn /as sysdba  
Connected.  
SQL> @marker_setup.sql  
 
Marker setup script.  
You will be prompted for the name of a schema for the Oracle GoldenGate database objects.  
NOTE: The schema must be created prior to running this script.  
NOTE: Stop all DDL replication before starting this installation.  
 
Enter Oracle GoldenGate schema name:ogg  
 
Marker setup table script. complete, running verification script...  
Please enter the name of a schema for the GoldenGate database objects:  
Setting schema name to OGG  
 
MARKER TABLE  
-------------------------------  
OK  
 
MARKER SEQUENCE  
-------------------------------  
OK  
 
Script. complete.  
 
SQL> show parameter recyclebin;  
 
NAME                                 TYPE        VALUE  
------------------------------------ ----------- ------------------------------  
recyclebin                           string      on  
 
SQL> alter session set recyclebin=off;  
System altered.  

SQL> alter system set recyclebin=off deferred; 
System altered.
 
SQL> show parameter recyclebin;  
 
NAME                                 TYPE        VALUE  
------------------------------------ ----------- ------------------------------  
recyclebin                           string      OFF  
 
1.回收站启动和关闭

回收站默认是开启的.不过我们可以通过参数recyclebin来关闭和开启.

如果只是针对每个session可以通过alter session set recyclebin=off; 和 alter session set recyclebin=on;来关闭和开启

如果是针对所有session可以通过修改系统参数recyclebin来实现,不过这里要注意10g和11g有点不一样,它们的参数类型不同

10g可以用:alter system set recyclebin=off; 和alter system set recyclebin=on;来关闭和开启

11g可以用:alter system set recyclebin=off deferred; 和alter system set recyclebin=on deferred;来关闭和开启



SQL> @ddl_setup.sql  
Oracle GoldenGate DDL Replication setup script.  
Verifying that current user has privileges to install DDL Replication...  
You will be prompted for the name of a schema for the Oracle GoldenGate database objects.  
NOTE: For an Oracle 10g source, the system recycle bin must be disabled. For Oracle 11g and later, it can be enabled.  
NOTE: The schema must be created prior to running this script.  
NOTE: Stop all DDL replication before starting this installation.  
Enter Oracle GoldenGate schema name:ogg  
 
Working, please wait ...  
Spooling to file ddl_setup_spool.txt  
 
Checking for sessions that are holding locks on Oracle Golden Gate metadata tables ...  
Check complete.  
Using OGG as a Oracle GoldenGate schema name.  
Working, please wait ...  
RECYCLEBIN must be empty.  
This installation will purge RECYCLEBIN for all users.  
To proceed, enter yes. To stop installation, enter no.  
 
Enter yes or no:yes  
————————其他输出省略————————  
 
STATUS OF DDL REPLICATION  
---------------------------------------------------------------------------------------  
SUCCESSFUL installation of DDL Replication software components  
 
Script. complete.  
 
SQL> @role_setup.sql  
GGS Role setup script.  
This script. will drop and recreate the role GGS_GGSUSER_ROLE  
To use a different role name, quit this script. and then edit the params.sql script. to change the gg_role parameter to the preferred name. (Do not run the script.)  
 
You will be prompted for the name of a schema for the GoldenGate database objects.  
NOTE: The schema must be created prior to running this script.  
NOTE: Stop all DDL replication before starting this installation.  
 
Enter GoldenGate schema name:ogg

3:source端修改extract进程的params文件,添加"ddl include all"参数,重启extract进程
GGSCI (db1) 1> view params eora_t1  
extract eora_t1  
setenv (NLS_LANG=AMERICAN_AMERICA.AL32UTF8)  
ddl include all

4:target端修改replicat进程的params文件,添加"ddl include all"和"ddlerror default ignore retryop maxretries 3 retrydelay 5" 参数,重启replicat进程
