我发现很多用户请求利用 Orchestrator 来创建集成,以获得一些有关某一安装过程的内部工作机制的信息,而这些信息都是无法通过 Web 服务所获得的。Web 服务可让您检索有关以下内容的信息:

  • 文件夹
  • Runbook
  • Runbook 参数
  • 活动
  • 作业
  • Runbook 实例
  • Runbook 实例参数
  • 活动实例
  • 活动实例数据
  • Runbook 服务器
  • Runbook 关系图
  • 统计信息
  • 事件

除了开始作业和停止作业以外,其他所有通过 Web 服务所获得的内容都是只读的。但是,用户还希望能够进行编程操作(和修改操作),并执行类似于以下的操作:

  • 查看并修改变量和计数器
  • 查看安装了哪些集成包
  • 查看日志历史记录
  • 导出或导入 Runbook
  • 签入或签出(或取消签出)Runbook
  • 查看哪位用户拥有连接到 Management Server 的 Runbook Designer

所有这些功能,以及更多功能均已通过 Orchestrator COM 界面可用。我将撰写一篇新的文章来解释如何连接到 COM 界面,并使用该界面来进行多个有助于您进一步自动化与 Orchestrator 交互的操作。由于使用 C# 代码进行编写和编译更为简单(对我而言这比使用 C++ 简单多了),因此我将在这些示例中使用 PowerShell。

首先,我将打开一个 PowerShell (x86) ISE(这是因为 Orchestrator 2012 为 64 位软件)。请注意,在这一示例中,您将需要在 Orchestrator Management Server 上进行操作。

我将使用以下命令在 PowerShell 中创建一个新项目:

$oismgr = new-object -com OpalisManagementService.OpalisManager

我可从这查看 COM 对象的内部,以及所有可用的方法列表(这些方法的数量很多!):

$oismgr | gm

很遗憾,其他地方都没有记录这些方法,因此有时您需要进行多次尝试才能使其正常运行,所幸的是,我将为您避免这些麻烦。在使用 COM 界面时,Orchestrator 中的安全模式仍然有效,而且您需要拥有管理员权限才能使用其中很多功能,因此,这实际上稍微提高了 Orchestrator 的限制程度,而这对于用户而言将是一条好消息。而且大多数操作需要用户(通过连接方法)建立一个连接句柄,但是用户也可在不进行连接的情况下使用一些方法(如 GetEvents)。此处所显示的一些界面并未真正实施,或可从外部代码中访问。

为了向您展示这些内容的工作原理,我将从可向您展示不需要任何连接句柄即可运行的 GetEvents 开始。对于许多方法而言,它们需要在一个对象周围设置一个“可变包装”,以创建该方法所预期的“可变”类型。此外,您还将经常在一个将成为该方法输出的引用变量中传递,而非在确实只是一个 HResult 代码的“返回值”中传递。

        $oismgr = new-object -com OpalisManagementService.OpalisManager
        $oevents = New-Object object
        $events = $events = New-Object Runtime.InteropServices.VariantWrapper($oevents)
        $oismgr.GetEvents([ref]$events)
        $xml = [XML]$events
        $xml.OuterXml

该方法将输出类似于以下内容的代码(我编排了该 XML 的格式,以更易于您查看):

<Events>
  <Event>
    <UniqueID>{09A4CEEE-8EBE-4D1C-B5DD-06DA3EBCE01A}</UniqueID>
    <Type>Information</Type>
    <Computer></Computer>
    <Summary>Completed Log Cleanup</Summary>
    <DateTime>
      129782594190000000
    </DateTime>
  </Event>
</Events>

因此,您可发现从 COM 界面中获取信息相对而言将简单很多。当然,我更愿意从 Web 服务中获取诸如事件之类的信息,因此这样更易于处理。现在,一起来看看我将如何执行需要凭据和连接的操作。将第一个参数显示为一个 int 的任何方法基本上都需要连接。例如,GetIntegrationPacks 方法。以下 PowerShell 脚本将使用连接方法来为 COM 界面创建一个连接句柄,并返回一个包含连接 ID 的整数。($Username 为 “<domain>\<username>”)

            $oismgr = new-object -com OpalisManagementService.OpalisManager
            $ohandle = New-Object object
            $handle = $handle = New-Object Runtime.InteropServices.VariantWrapper($ohandle)
            $retval = $oismgr.Connect($UserName, $password, [ref]$handle)
            $handle

然后,您将使用该句柄 ID 作为该“需要连接”的方法的首个参数,如下:

            $odetails = new-object object
            $ipdetails = $evdetails = New-Object Runtime.InteropServices.VariantWrapper($odetails)
            $retval = $oismgr.GetIntegrationPacks($Handle, [ref]$ipdetails)
            $output = [XML]$ipdetails
            $output.OuterXml

上述代码将生成类似于以下的 XML(我编排了其格式,以便于您查看):

<IntegrationPacks>
  <IntegrationPack>
    <UniqueIDdatatype="string">{12A45CB8-39DE-43A7-8FA2-E90379A5091F}</UniqueID>
    <Namedatatype="string">System Center Integration Pack for Microsoft .NET Framework Activities</Name>
    <Descriptiondatatype="string">Activities for Orchestrator Integration Toolkit for Microsoft .NET</Description>
    <Versiondatatype="int64">7</Version>
    <Librarydatatype="string">Microsoft.SystemCenter.Orchestrator.Integration.Toolkit.IP.ServerExtension.dll</Library>
    <ProductNamedatatype="string">{12A45CB8-39DE-43a7-8FA2-E90379A5091F}.OIP</ProductName>
    <ProductIDdatatype="string">{E88EF9F3-448F-49DC-BF02-2C93BFC8BB29}</ProductID>
  </IntegrationPack>
</IntegrationPacks>

正如您可看到的,获得这些信息将十分容易。实际上,我编写了一个 PowerShell 脚本,该脚本可在您将其导入之前验证 Runbook,以确保 Runbook 中所含的活动实际上已安装,并作为 IP 中的一部分,从而您无需导入 Runbook,并获得不必要的“未知”活动。…

今后我将继续这一博文系列,向您介绍有关如何在 COM 界面中使用更多方法的信息。希望您届时您能享受编码的过程!:)
