linux下oracle通过unixODBC连接MySQL

1-安装unixODBC

tar zxvf unixODBC-2.2.12.tar.gz(或者tar.tar)

cd unixODBC-2.2.12

./configure --prefix=/usr/local/unixODBC-2.2.12 --includedir=/usr/include --libdir=/usr/lib -bindir=/usr/bin --sysconfdir=/etc

make

make install

2-将mysql驱动拷贝到linux，放到lib或lib64目录

3-配置odbc，并使用isql命令测试odbc

/etc/odbc.ini

[myodbc_test]

Driver = /usr/lib64/libmyodbc5.so

Server = 192.168.2.1

User = root

Password = root

Port = 3306

database = fpyj_sms

显示以下内容表示测试连接成功：

[root@linux-vm001 ~]# isql myodbc_test

+---------------------------------------+

| Connected! |

| |

| sql-statement |

| help [tablename] |

| quit |

| |

+---------------------------------------+

SQL>

4-配置oracle监听

$TNS_ADMIN/listener.ora文件中添加

SID_LIST_LISTENER =

(SID_LIST =

(SID_DESC =

(SID_NAME = dg4odbc)

(ORACLE_HOME = /u01/app/oracle/product/11.2.0/dbhome_1)

(PROGRAM = dg4odbc)

)

)

5-配置oracle监听启动文件

$ORACLE_HOME/hs/admin/下添加文件 init名称.ora(如initdg4odbc.ora)

# This is a sample agent init file that contains the HS parameters that are

# needed for the Database Gateway for ODBC

#

# HS init parameters

#

HS_FDS_CONNECT_INFO = myodbc_test

HS_FDS_TRACE_LEVEL = off

HS_FDS_SHAREABLE_NAME = /usr/lib64/libmyodbc5.so

#

# ODBC specific environment variables

#

set ODBCINI=/etc/odbc.ini

#

# Environment variables required for the non-Oracle system

#

#set <envvar>=<value>

6-配置客户端连接tns

$TNS_ADMIN/tnsnames.ora文件中添加连接

dg4odbc =

(DESCRIPTION=

(ADDRESS=(PROTOCOL=tcp)(HOST=localhost)(PORT=1521))

(CONNECT_DATA=(SID=dg4odbc))

(HS=OK)

)

7-建立db_link操作mysql

drop database link db4smsoto;

create database link db4smsoto

connect to "root"

identified by "y4yhl9tbz"

using 'dg4odbc';

或者省略第六步，直接建立db_link

drop database link db4smsoto;

create database link db4smsoto

connect to "root"

identified by "y4yhl9tbz"

using '(DESCRIPTION=

(ADDRESS=(PROTOCOL=tcp)(HOST=localhost)(PORT=1521))

(CONNECT_DATA=(SID=myodbc4smsoto))

(HS=OK)

)';
