首先Orcale的安装应该是很简单的，安装不好只是部熟悉，在其中遇见的一些问题记录下来，如果以后忘记了还可以看看。
首先最大的问题是安装客户端的时候要安装32位的，不管你的操作系统是32位还是64位的。
然后安装好后需要配置一些配置信息 E:\app\John\product\11.2.0\client_1\NETWORK\ADMIN 找到这个目录下的tnsnames.ora 文件
tnsnames.ora Network Configuration File: D:\app\wang\product\11.1.0\client_1\NETWORK\ADMIN\tnsnames.ora
# Generated by Oracle configuration tools. ORA_6.175 =

)
(CONNECT_DATA =
(SID = ORCL)
)
) orcl_192.168.200.146 =

ORCL_110 =

ZBDBRAC =

(LOAD_BALANCE = yes)

(CONNECT_DATA =

)
像这样配置 将Host改成你需要连接的服务器地址。
