一.安装unixODBC
UnixODBC官网：
http://www.unixodbc.org/
[root@rac1 mnt]# yum installunixODBC
[root@rac1 mnt]# yum installunixODBC-devel
确认unixODBC的安装，使用isql命令，其是unixODBC自带的命令。可以使用这个命令验证unixODBC的配置。
[root@rac1 /]# isql --version
unixODBC 2.2.14
[root@rac1 /]# which isql
/usr/bin/isql
[root@rac1 /]# isql

二．
下载安装unixODBC 连接Oracle 的驱动
ODBC Drivers 下载地址：
http://www.easysoft.com/developer/interfaces/odbc/index.
html
这里的驱动也分两种，需要Oracle 客户端的ODBC-Oracle Driver (OCI version)和不需要Oracle客户端的ODBC-OracleDriver (
WP version)，
The EasysoftODBC-
Oracle Driver (OCI version) uses Oracleclient software to access the Oracle database.
The EasysoftODBC-Oracle Driver (WP version), which does not use Oracle client software,provides direct access to Oracle, for use in solutions where minimising theclient footprint is a requirement.
因为我的测试环境上已经安装了oracle，所以我这里选择需要客户端的驱动。
[root@rac1 u01]# ls
app backup odbc-oracle-3.3.0-linux-x86-64-ul64.tar oswbb oswbb4.0.tar
安装odbc 驱动：
[root@rac1 u01]# tar -xvf odbc-oracle-3.3.0-linux-x86-64-ul64.tar
[root@rac1 u01]# cd odbc-oracle-3.3.0-linux-x86-64-ul64
[root@rac1odbc-oracle-3.3.0-linux-x86-64-ul64]# ls
all.tar |
