不用安装Oracle Client 如何使用PLSQL Developer-asdfghjkl
1. 下载oracle的客户端程序包（30M） 只需要在Oracle下载一个叫Instant Client Package的软件就可以了，这个软件不需要安装，只要解压就可以用了，很方便，就算重装了系统还是可以用的。下载地址：http://www.oracle.com/technology/software/tech/oci/instantclient/htdocs/winsoft.html
解压到一个目录中即可，例如c:\oracleclient
2. 配置操作系统环境变量
NLS_LANG=SIMPLIFIED CHINESE_CHINA.ZHS16GBK
TNS_ADMIN = D:\Program Files\oracleclient\instantclient_11_2
3. 配置连接Oracle的配置。tnsnames.ora文件到目录
D:\Program Files\oracleclient\instantclient_11_2。可以从oracle服务器拷贝一个过来。
内容类似： # tnsnames.ora Network Configuration File: E:\oracle\product\10.2.0\db_1\network\admin\tnsnames.ora
# Generated by Oracle configuration tools.
ORCLProduct =

EXTPROC_CONNECTION_DATA =
(DESCRIPTION =
(ADDRESS_LIST =

)

)
)
4. 安装PLSQL Developer
5. 配置PLSQL Developer（第一次可以不用登录直接进到PLSQL Developer）
