for循环中的powershell和sqlplus脚本

Question

所以我对Powershell还是很陌生，我有一个Oracle sql Scipt，我想在Powershell循环中运行

读取文本文件以读取服务器列表的功能。

$oracleServers     = "C:\Temp\oracle-servers.txt"

function Database-Servers
 {
   $servers = Get-Content $oracleServers
   Return($servers.Trim())
 }

接下来，我从该列表中读取正在运行的Oracle Services

功能已安装的数据库

$svr        = $args[0]
$runningDBs = " "

$runningDBs = Get-Service -Name "OracleService*" -ComputerName $svr | 
Select-Object -ExpandProperty name | Out-String | % {$_.replace("OracleService","")}  

Return($runningDBs)

 function ConnectString
 {
   $CString     = " " #$args[0]

   foreach ($server in Database-Servers) 
   {
    $runningDBs = Installed-Databases $server
    $rdblist    = $runningDBs -split '[\n]'
        foreach ( $rdb in $rdblist) 
             {
             if(!$rdb -eq " ")
              {
               $CString = ' system/$rdb@$server$tnsalias$rdb'
               &sqlplus $CString  $scriptsql | out-file  $outputfile
                 Write-Host $CString
                 Return($CString)
               }
             }
   }
}
