使用powershell脚本批量更新客户端配置文件

2012-1-11

背景：

Oracle升级并且服务器和IP地址同时更新，系统架构是2层C/S架构的，面临的是客户端200+需要更新tnsnames.ora，且Oracle安装目录不一致，稍让安心的是Oracle客户端版本是统一的， OS都是windows 系统，并且都加入域。

解决方案：

使用powershell脚本在服务器端推送新版的tnsnames.ora

实施步骤：

结合.Net 框架编写远程读写注册表测试脚本

write-output "Replace TNSNames.ora now`nPlease Wait..."
