oracle通过dblink连接mysql配置详解(全Windows下)

关于oracle通过dblink连接mysql,经过了两周的空闲时间研究学习,终于配置好了,真是不容易啊,仔细想想的话,其实也没花多长时间,就是刚开始走了一段弯路,所以把这次的经验分享出来,让大家少走些弯路,OK,闲话不多说了,开始配置旅程: 
一:环境检查: 
数据库:安装oracle11g 64位,安装mysql 5.6 64位,Windows7系统;

安装数据源驱动(ODBC) 64位,Windows7系统;

数据源下载地址:http://pan.baidu.com/s/1dFeGUDr(我的百度云盘内); 
接下来需要检查的是否安装了oracle透明网关,如下图所示: 

 

 

二:检查之后没问题开始安装: 
(1)在开始菜单中搜索ODBC:

 

 

打开后选择系统DSN:

 

 

 
选择第一个就可以了

 

 

 

 

配置完成后点击完成就可以了,这样Mysql的ODBC就已经有了

(2)接下来进行oracle透明网关配置:

找到你的oracle的安装目录的initdg4odbc.ora文件(我安装在E盘):

E:\app\Administrator\product\11.2.0\dbhome_1\hs\admin(这是我 
安装在E盘下面),然后复制一份,命名规则是:init+sid.ora,所以就是initmysqlodbc.ora;

然后打开initmysqlodbc.ora文件,添加如下内容:

HS_FDS_CONNECT_INFO = mysqlodbc 说明:和mysql的odbc保持一致 
HS_FDS_TRACE_LEVEL = off 说明:需要调试时可以改为debug,调试完成改为off;

然后打开E:\app\Administrator\product\11.2.0\dbhome_1\NETWORK\ADMIN 的listener.ora文件:

# listener.ora Network Configuration File: E:\app\Administrator\product\11.2.0\dbhome_1\NETWORK\ADMIN\listener.ora
# Generated by Oracle configuration tools.

SID_LIST_LISTENER =
  (SID_LIST =
    (SID_DESC =
      (SID_NAME = CLRExtProc)
      (ORACLE_HOME = E:\app\Administrator\product\11.2.0\dbhome_1)
      (PROGRAM = extproc)
      (ENVS = "EXTPROC_DLLS=ONLY:E:\app\Administrator\product\11.2.0\dbhome_1\bin\oraclr11.dll")
    )
      ***(SID_DESC = 
      (SID_NAME = MYSQLODBC)
      (ORACLE_HOME = E:\app\Administrator\product\11.2.0\dbhome_1)
      (PROGRAM = dg4odbc)
     )*** 
  )

LISTENER =
  (DESCRIPTION_LIST =
    (DESCRIPTION =
      (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))
      (ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1521))
    )
  )

ADR_BASE_LISTENER = E:\app\Administrator

带星号字体为配置部分;。。。!!!粘贴时要注意,括号上和上边下边的对齐,否则启动监听报错。。。!!!

然后重启监服务,可以在service.msc里重启,也可以使用命令lsnrctl stop ,lsnrctl start;

接下来打开tnsnames.ora(跟监听配置文件在同一个目录下)

# tnsnames.ora Network Configuration File: E:\app\Administrator\product\11.2.0\dbhome_1\NETWORK\ADMIN\tnsnames.ora
# Generated by Oracle configuration tools.

LISTENER_ORCL =
  (ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1521))


ORACLR_CONNECTION_DATA =
  (DESCRIPTION =
    (ADDRESS_LIST =
      (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))
    )
    (CONNECT_DATA =
      (SID = CLRExtProc)
      (PRESENTATION = RO)
    )
  )

ORCL =
  (DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1521))
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = orcl)
    )
  )

**MYSQLODBC =
  (DESCRIPTION =
    (ADDRESS_LIST =
      (ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1521))
    )
    (CONNECT_DATA =
      (SERVICE_NAME = mysqlodbc)
    )
    (HS = OK)
  )**

带星号字体为新添加的配置(mysqlodbc),保存;

最后用oracle连接工具创建dblink:

create database link mysqlodbc connect to "root" identified by "123456" using 'mysqlodbc';--注意使用单引号
  • 1
  • 1

测试一下是否能够连接,提示连接成功说明能够访问mysql; 

 

 

为了进一步验证,我这里还做了新增数据的测试(不要忘记点击提交按钮,不然在mysql客户端无法查到数据):

 

 

然后再次查询,能查得到: 

 

 

接着我再到mysql去查询,也能查到: 

 

 

到这里已经将所有的配置完成
