42. デザイナで構築するアプローチ
SQL Server Integration Services
DB に対しての保守タスクや
データの操作等をドラッグ＆ド
ロップしてワークフロー化する
RunBook 上に何かしらの操作や
トリガとなるアクティビティを配置
結びつけてワークフロー化する
System Center Orchestrator
45. Dim objWMIResult
Dim objLocator
Dim objService ローカルのホスト名を取得
Dim objWMIClass
Dim strPCName
する VBS スクリプト
'ローカルコンピュータに接続しクエリを実行する
objLocator = WScript.CreateObject("WbemScripting.SWbemLocator")
objService = objLocator.ConnectServer
objWMIResult = objService.ExecQuery("Select * From Win32_OperatingSystem")
„結果の取得
For Each objWMIClass In objWMIResult
strPCName = objWMIClass.CSName
Next
objWMIResult = Nothing
objWMIClass = Nothing
objService = Nothing
objLocator = Nothing
VBS スクリプトは構文的に VB.NET に近いので
C# 等を利用するよりも移植は行いやすい
（あくまでも個人的な感想です）
46. スクリプトを移植しアクティビティ化
