我想在當前用戶的本地或遠程機器中執行下面的代碼。如果我使用powershell invoke-command不起作用--computerName
$BackUpSqlAgentAndRemoveOldbackup = {
param([string]$AppServer,[string]$SqlInstance,[string]$BackupShare,[string]$alias)
[Environment]::UserName #I got same user name in all cases.
[System.Reflection.Assembly]::LoadWithPartialName('Microsoft.SqlServer.Smo') | Out-Null
$server = New-Object ('Microsoft.SqlServer.Management.Smo.Server') $SqlInstance
$backupName = 'SqlAgentJob_' + $SqlInstance + '_' + (Get-Date –format ‘yyyyMMdd_HHmm’) + '_' + $alias + '.sql'
$backupPath = join-path $BackupShare $backupName
$oldBackups = Get-ChildItem $backupShare | where { ($_.name -like 'SqlAgentJob_*.sql') }
$server.JobServer.Jobs.Script() | Out-File -filepath $backupPath
foreach ($item in $oldBackups) { remove-item $item.fullName }
}
的@argList是
@('hafcapp-1', 'hafcsql-1', '\\Host5FileSrv\Backup\test','auto')
我注意到
這一塊，它工作得很好（無-comupterName和-session）
Invoke-Command -ScriptBlock $BackUpSqlAgentAndRemoveOldbackup -argumentList $argList
這一塊，它拋出執行（我也試過「 - 激情」，得到相同的結果）
Invoke-Command -computerName localhost -ScriptBlock $BackUpSqlAgentAndRemoveOldbackup -argumentList $argList
異常情況如下，看來它不能訪問該文件夾。
Cannot find path '\\Host5FileSrv\Backup\test' because it does not exist.

You cannot call a method on a null-valued expression.

+ CategoryInfo : InvalidData: (:) [Remove-Item], ParameterBindingValidationException
+ FullyQualifiedErrorId : ParameterArgumentValidationErrorNullNotAllowed,Microsoft.PowerShell.Commands.RemoveItemCommand
沒有人知道如果我想添加computerName或session，該怎麼辦？ （注：[環境] ::用戶名返回相同的用戶）
