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

View Code
1 $MachineName = '.'
2 
3 $reg=[Microsoft.Win32.RegistryKey]::OpenRemoteBaseKey('LocalMachine', $MachineName)
4 
5 [System.String]$name="SOFTWARE\Oracle\KEY_OraClient11g_home1"
6 
7 $regKey= $reg.OpenSubKey($name).GetValue("ORACLE_HOME")

Powershell脚本读取PC列表,这部份没有编写代码,主要是这部分机器都属于CSR座席,在CIC系统中直接可以导出,稍处理后保存在pclist.txt即可使用。 

最终脚本(主要一次性的操作,没有规划成函数调用方式):
