UserExit的使用

   以下示例主要是用来判断内存大小C盘空间大小及系统盘符,然后自动选择执行不同的任务序列,具体想依据什么来判断,可参考ZTIGahter.log中的变量

一、依据内存大小,选择执行不同的TS

法一:

wKioJlLEKr7juUIoAABjno-GS_c483.jpg

Userexit=MyCustomFunctions.vbs

TaskSequenceID=#GetTSID()#


然后将MyCustomFunctions.vbs脚本添加到\\MDT2012\DeploymentShare$\scripts文件夹下即可。

Function UserExit(sType, sWhen, sDetail, bSkip)
                UserExit = Success
End Function
Function GetTSID()
                If oEnvironment.Item("Memory") < 1024 Then
                                GetTSID = "WIN7_TS1"
                Else
                                GetTSID = "WIN7_TS2"
                End if
End Function


法二:(未借助MDT原有变量Memory,自定义的变量)

Userexit=1.vbs

TaskSequenceID=#GetTSID()#


Function UserExit(sType, sWhen, sDetail, bSkip)
                UserExit = Success
End Function
Function GetTSID()
        strComputer = "."
        Set objWMI = GetObject("winmgmts:\\" & strComputer)
        Set colItems = objWMI.ExecQuery("Select * from Win32_OperatingSystem")
        For Each objItem in colItems
            If objItem.TotalVisibleMemorySize / 1024 > 1024 Then
                                GetTSID = "WIN7_TS1"
                    Else
                                GetTSID = "WIN7_TS2"
                    End if
        Next
                                                                                                 
End Function


法三:

Userexit=2.vbs

TaskSequenceID=#SetTaskSequence(%Memory%)#


Function UserExit(sType, sWhen, sDetail, bSkip)
  UserExit = Success
End Function
Function SetTaskSequence(Memory)
oLogging.CreateEntry "UserExit - Determining Task " & _
    "Sequence to run based on available RAM", LogTypeInfo
                                                                           
  If Memory <= 2048 Then
    SetTaskSequence = "Win7_TS2"
    oLogging.CreateEntry "UserExit - Available RAM: " & _
      Memory & ". Selecting Win7_Ts2 TS.", LogTypeInfo
  Else
    SetTaskSequence = "Win7_TS1"
    oLogging.CreateEntry "UserExit - Available RAM: " & _
      Memory & ". Selecting Win7_TS1 TS.", LogTypeInfo
End If
End Function



二、依据内存、磁盘空间大小并判断是否为系统盘符决定是否进行Refresh升级

          GetTSID = "WIN7_TS3"
' //如果目标机器满足以上要求且内存大于1000M则执行Win7_TS7,小于则执行Win7_TS5.
        Elseif oEnvironment.Item("Memory") >1000 Then
          GetTSID = "WIN7_TS7"
        Else
          GetTSID = "WIN7_TS5"
        End If
      End If
    End If
' //跳出IF语句,执行下一步
  Next
End Function
