Oracle 11gR2 访问 MySql 5.6

一、环境信息

           操作系统

Red Hat Enterprise Linux Server release 6.4 (Santiago)

           Oracle版本信息

Oracle Database 11g Enterprise Edition Release 11.2.0.4.0 - 64bit Production

          MySQL版本信息

mysql-community-server-5.6.27-2.el6.x86_64 

主机信息         

hostname	Ip-address	database
bakstore	10.9.9.x	oracle
tsl-ic-stg-db	10.9.5.x	mysql

二、程序包信息

          mysql-connector-odbc-5.3.9-linux-el6-x86-64bit.tar.gz

          unixODBC-2.3.4.tar.gz

三、配置过程

          1.登录oracle用户：su – ora11

          2.查看ODBC信息

file $ORACLE_HOME/bin/dg4odbc

          3.安装ODBC Driver Manager

tar -zxvfunixODBC-2.3.4.tar.gz

cd unixODBC-2.3.4

./configure --prefix=/opt/odb/uodbc --disable-gui --enable-threads --disable-drivers

make

make install

          4.安装ODBC Driver for MySQL

tar -zxvf mysql-connector-odbc-5.3.9-linux-el6-x86-64bit.tar.gz

mv mysql-connector-odbc-5.3.9-linux-el6-x86-64bit ~/oracle

cd ~/oracle

ln -s mysql-connector-odbc-5.3.9-linux-el6-x86-64bit/ myodbc-5.3.9

         5.配置ODBC Driver

cd /opt/odb/uodbc/etc

vi odbc.ini

[ODBC Data Sources]
data_source_name = myodbc5w
data_source_name = myodbc5a

[myodbc5w]
Driver          = /home/ora11/oracle/myodbc-5.3.9/lib/libmyodbc5w.so
DATABASE        = tasly-ic
DESCRIPTION     = MySQL ODBC 5.3 Unicode Driver test
SERVER          = 10.9.5.138
UID             = test
PASSWORD        = 123456
PORT            = 3306


[myodbc5a]
Driver          = /home/ora11/oracle/myodbc-5.3.9/lib/libmyodbc5a.so
DATABASE        = tasly-ic
DESCRIPTION     = MySQL ODBC 5.3 Unicode Driver test
SERVER          = 10.9.5.138
UID             = test
PASSWORD        = 123456
PORT            = 3306

注：Driver指第三步ODBC Driver for MySQL

          6.oracle用户环境变量

vi ~/.bash_profile

export ODBCHOME=/opt/odb/uodbc
export ODBCSYSINI=${ODBCHOME}/etc
export ODBCINI=${ODBCSYSINI}/odbc.ini
export LD_LIBRARY_PATH=$ORACLE_HOME/lib:/lib:/usr/lib:/usr/share/lib:${ODBCHOME}/lib:/home/ora11/oracle/myodbc-5.3.9/lib
export LD_LIBRARY_PATH

          7.配置initmyodbc5w.ora

vi $ORACLE_HOME/hs/admin/initmyodbc5w.ora

HS_FDS_CONNECT_INFO=myodbc5w # Data source name in odbc.ini  
HS_FDS_SHAREABLE_NAME=/opt/odb/uodbc/lib/libodbc.so  
HS_FDS_SUPPORT_STATISTICS=FALSE  
HS_LANGUAGE=AMERICAN_AMERICA.WE8ISO8859P15  
  
# ODBC env variables  
set ODBCINI=/opt/odb/uodbc/etc/odbc.ini

          8.测试ODBC连接

cd /opt/odb/uodbc/bin

./isql -v myodbc5w

+---------------------------------------+  
| Connected!                            |  
|                                       |  
| sql-statement                         |  
| help [tablename]                      |  
| quit                                  |  
|                                       |  
+---------------------------------------+  

上面显示连接成功。

          9.查看odbc配置

cd /opt/odb/uodbc/bin

./odbcinst -j

unixODBC 2.2.14
DRIVERS............: /opt/odb/uodbc/etc/odbcinst.ini
SYSTEM DATA SOURCES: /opt/odb/uodbc/etc/odbc.ini
FILE DATA SOURCES..: /opt/odb/uodbc/etc/ODBCDataSources
USER DATA SOURCES..: /opt/odb/uodbc/etc/odbc.ini
SQLULEN Size.......: 8
SQLLEN Size........: 8
SQLSETPOSIROW Size.: 8

          10.配置tnsnames.ora

cd $ORACLE_HOME/network/admin

vi tnsnames.ora

myodbc5w =  
  (DESCRIPTION=  
    (ADDRESS=  
        (PROTOCOL=TCP) (HOST = bakstore) (PORT=1520)  
    )  
    (CONNECT_DATA=  
      (SID=myodbc5w)  
    )  
    (HS=OK)  
)  

          11.配置listener.ora

cd $ORACLE_HOME/network/admin

vi listener.ora

SID_LIST_LISTENER2=
  (SID_LIST=
	(SID_DESC=
		(SID_NAME = myodbc5w)
		(ORACLE_HOME = /home/ora11/oracle/product/11.2.0/dbhome_1)
		(PROGRAM = dg4odbc)
		(ENVS = LD_LIBRARY_PATH=/opt/odb/uodbc/lib:/home/oracle/app/oracle/product/11.2.0/dbhome_1/lib)
	)
  )
LISTENER2 = 
	(DESCRIPTION_LIST = 
		(DESCRIPTION = 
			(ADDRESS = (PROTOCOL = tcp)(HOST = bakstore)(PORT = 1520))
		)
		)

          启动listener2

lsnrctlstart listener2

lsnrctl status listener2

          验证myodbc5w

tnsping myodbc5w

          12.创建database link

create public database link mysql1 connect to "test" identified by "123456" using 'myodbc5w';
test --- mysql用户
123456 --- mysql用户密码
myodbc5w --- tnsnames名

          13.登录oracle查询mysql数据

select * from "ic_user"@mysql1;

至此oracle可以访问mysql数据
