ogg for oracle to ogg for mysql

源端是oracle数据库。目标端是mysql数据库。源端的配置就是前一篇文章中的配置。基础的配置都一样的。没啥好说。具体的往下看

源端

创建wu.mytable表，这是测试表

添加抽取进程，不使用数据泵

GGSCI (primary) 43> edit param ext_my
extract ext_my
userid ogg,password oracle
setenv (NLS_LANG = "AMERICAN_AMERICA.AL32UTF8")
setenv (ORACLE_HOME = "/u01/app/oracle10g")
setenv (ORACLE_SID = ocp)
exttrail ./dirdat/my
rmthost 192.168.1.12,mgrport 7810
rmttrail /app/ogg/dirdat/my
table wu.mytable;

GGSCI (primary) 44> add extract ext_my,tranlog, begin now;;
EXTRACT added.

GGSCI (primary) 45> dblogin userid ogg
Password: 
Successfully logged into database.

GGSCI (primary) 47> add trandata wu.mytable

Logging of supplemental redo data enabled for table WU.MYTABLE.

GGSCI (primary) 49> add exttrail ./dirdat/my,extract ext_my,megabytes 100
EXTTRAIL added.

GGSCI (primary) 51> add rmttrail /app/ogg/dirdat/my,extract ext_my,megabytes 100
RMTTRAIL added.

设置定义文件

GGSCI (primary) 53>  edit params defgen
defsfile ./dirdef/mytable.def
userid ogg,password oracle
table wu.mytable;
然后退出到shell下

[oracle@primary ogg]$ more ./dirprm/defgen.prm
defsfile ./dirdef/mytable.def
userid ogg,password oracle
table wu.mytable;
[oracle@primary ogg]$ ./defgen paramfile ./dirprm/defgen.prm

把这个文件拷到mysql端ogg的相同目录。比如我的为/app/ogg/dirdef/mytable.def。oracle是源段，有一个ogg。mysql是目的端，有一个ogg。比如我的是从源段/u01/app/ogg/dirdef/mytable.def拷到目的端/app/ogg//dirdef/mytable.def。

exttrail ./dirdat/my
rmthost 192.168.1.12,mgrport 7810
rmttrail /app/ogg/dirdat/my
table wu.mytable;

源段配置完毕

目标端mysql配置。

mysql安装见我另外一篇文章。http://blog.csdn.net/shliesce/article/details/10428911

然后创建oggtest数据库。从oracle复制过来的wu.mytable表就是放在oggtest.mytable中。

ogg for mysql这个大家就自己下载吧。我是从别人那里拷来的。官网地址需要邮箱认证。不嫌麻烦的朋友认证下就可以了。

ogg的安装和之前一样。unzip，tar,create suddirs。这里一笔带过。因为这些是最基本的安装。大家应该都知道了。不会的话看我另一篇博文http://blog.csdn.net/shliesce/article/details/10429251

ERROR: Failed to connect to MySQL database engine for HOST localhost, DATABASE , USER root, PORT 3306.
因为我安装mysql的时候socket文件默认是/app/mysql/mysql.socket。这里他默认是找/tmp/mysql.sock这个默认位置的。解决方法是ln -s /app/mysql/mysql.socket  /tmp/mysql.sock

配置完成。下面测试

oracle端wu用户下

SQL> insert into mytable values(1,'a');


1 row created.


SQL> commit;


Commit complete.


SQL> insert into mytable values(2,'b');


1 row created.


SQL> commit;


Commit complete.


SQL> select * from mytable;


        ID NAME
---------- ----------
         1 a
         2 b

目的端mysql下oggtest数据库下查看

mysql> select * from oggtest.mytable;
+----+------+
| id | name |
+----+------+
|  1 | a    |
|  2 | b    |
+----+------+
2 rows in set (0.00 sec)

成功。OK~~
