UnixODBC官网：http://www.unixodbc.org/
这里使用YUM安装，不多说：
[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
