安装PLSQL Developer 连接运程Oracle 数据库
PLSQL Developer 包含两个部分一个是PLSQL Developer可视化界面，一个是instantclient客户端
解压缩包，压缩包下面包含上面两个内容
在安装目录下，新建三个文件夹，用来放：客户端环境，可视化界面安装包，可视化界面安装的目录
在安装包里面找到plsqldev906.exe双击进行安装
配置环境变量：
NLS_LANG = SIMPLIFIED CHINESE_CHINA.ZHS16GBK
TNS_ADMIN = E:\PLSQLDeveloper\SetUPOci\PLSQL\instantclient_11_2\network\admin
TNS_ADMIN是tnsnames.ora 的父级目录，为了能够找数据库；network\admin\tnsnames.ora文件是客户端环境里面的文件，需要自己配置，下载的压缩包没有
tnsnames.ora文件里面的内容
