Sql server Powershell还原脚本超时

我有一个Powershell脚本，我一直在使用它来自动化我的数据库恢复，它已经工作了一段时间，没有任何问题了

最近它开始失败并抛出超时错误

要突出显示该示例中的代码块，请执行以下操作：

    param([string] $newDBName, [string] $backupFilePath, [bool] $isNetworkPath = $true, [string] $newDataPath, [string] $newLogPath)

        # Create sql server object
        $server = New-Object ("Microsoft.SqlServer.Management.Smo.Server") "(local)"

        # Copy database locally if backup file is on a network share
        if($isNetworkPath)
        {
            $fileName = [IO.Path]::GetFileName($backupFilePath)
            $localPath = Join-Path -Path $server.DefaultFile -ChildPath $fileName
            Copy-Item $backupFilePath $localPath
            $backupFilePath = $localPath
        }

        $smoRestore.Action = "Database"

        # Create location to restore from
        $backupDevice = New-Object("Microsoft.SqlServer.Management.Smo.BackupDeviceItem") ($backupFilePath, "File") 
        $smoRestore.Devices.Add($backupDevice)

        # Give empty string a nice name
        $empty = ""

        # Specify new data file (mdf)

           $smoRestoreDataFile = New-Object("Microsoft.SqlServer.Management.Smo.RelocateFile")
            if (($newDataPath -eq $null) -or ($newDataPath -eq $empty)) { #use exixting path
           $defaultData = $server.DefaultFile
            if (($defaultData -eq $null) -or ($defaultData -eq $empty))
            {
                $defaultData = $server.MasterDBPath
            }
        } Else {$defaultData = $newDataPath}
        $fullPath = Join-Path -Path $defaultData -ChildPath ($newDBName + "_Data.mdf")
        $smoRestoreDataFile.PhysicalFileName = $fullPath

        # Specify new log file (ldf)
        $smoRestoreLogFile = New-Object("Microsoft.SqlServer.Management.Smo.RelocateFile")
        if (($newLogPath -eq $null) -or ($newLogPath -eq $empty)) { #use exixting path
            $defaultLog = $server.DefaultLog
            if (($defaultLog -eq $null) -or ($defaultLog -eq $empty))
            {
                $defaultLog = $server.MasterDBLogPath
            } 
        } Else {$defaultLog = $newLogPath}
        $fullPath = Join-Path -Path $defaultLog -ChildPath ($newDBName + "_Log.ldf")
        $smoRestoreLogFile.PhysicalFileName = $fullPath

        # Get the file list from backup file
        $dbFileList = $smoRestore.ReadFileList($server)

        # The logical file names should be the logical filename stored in the backup media
        $smoRestoreDataFile.LogicalFileName = $dbFileList.Select("Type = 'D'")[0].LogicalName
        $smoRestoreLogFile.LogicalFileName = $dbFileList.Select("Type = 'L'")[0].LogicalName

        # Add the new data and log files to relocate to
        $smoRestore.RelocateFiles.Add($smoRestoreDataFile)
        $smoRestore.RelocateFiles.Add($smoRestoreLogFile)

        # Restore the database
        $smoRestore.SqlRestore($server)

        "Database restore completed successfully"
    }
    catch [Exception]
    {
        "Database restore failed:`n`n " + $_.Exception
    }
    finally
    {
        # Clean up copied backup file after restore completes successfully
        if($isNetworkPath)
        {
            Remove-Item $backupFilePath
        }
    }
}

在执行实际还原时，会抛出以下错误：

我尝试查看了Powershell文档和其他链接，注意到一些网站提到Powershell cmdlet有600秒的默认超时

我正试图从Powershell或SQL Server中找到一种解决方案来增加此超时时间，但我在文档或常规web搜索方面没有什么运气

我的脚本是否有任何快速修复方法来增加超时或简单的替代方法

非常感谢您的帮助。

您在脚本中使用invoke-sqlcmd命令吗？@Venkatakrishnan我刚刚在谷歌上搜索了

invoke-sqlcmd

，现在我想我对

cmdlet

是什么感到有些困惑。我没有在Powershell脚本中使用

invoke sqlcmd

，所以我想我的问题不是默认的600秒超时。但这仍然是一个超时问题。您知道扩展此功能的任何解决方案吗？如果您在脚本中使用invoke-sqlcmd，则默认情况下需要600秒的超时时间。因为invoke-sqlcmd是一个内置命令，它是SQLPS模块的一部分。如果这是条件，我可以为您提供一个函数，您可以在其中更改超时value@Venkatakrishnan实际上，我正在使用这个方法来实际恢复我的数据库。没有从我的Powershell脚本执行任何SQL命令。您可以检查我的

try

块中的最后一行代码。如果不介意，请发布用于还原的完整脚本
