如何配置XenDesktop使用Mirror數據庫

在XenDesktop的部署過程中如果是用SQL Mirror的方式我們建議用戶在配置好Mirror之后在初始化XenDesktop站點配置，這樣在Connection string中默認會包含mirror數據庫連接。但是有時候難免會有用戶出現先配置站點以后在配置mirror，這樣就會讓事情變的非常復雜，需要幾十條命令重置所有service的connection string，稍有不慎可能導致環境掛掉。這里我整理了2段簡單的腳本供大家使用。

注意事項

1. 修改前務必對DDC和DB做快照
2. 此腳本僅適用于7.15 LTSR, 不同的版本服務數量會有差異，請自行修改

具體步驟

1. 我們首先需要將DDC中的connection string置空，您可以將一下內容保存為ps1文件到DDC上通過管理員權限執行
   Set-ItemProperty -Path HKLM:\SOFTWARE\Citrix\DesktopServer\DataStore\Connections\Controller ConnectionString $null
   Set-ItemProperty -Path HKLM:\SOFTWARE\Citrix\XDservices\ADIdentitySchema\DataStore\Connections ConnectionString $null
   Set-ItemProperty -Path HKLM:\SOFTWARE\Citrix\XDservices\Analytics\DataStore\Connections ConnectionString $null
   Set-ItemProperty -Path HKLM:\SOFTWARE\Citrix\XDservices\AppLibrarySchema\DataStore\Connections ConnectionString $null
   Set-ItemProperty -Path HKLM:\SOFTWARE\Citrix\XDservices\ConfigLoggingSiteSchema\DataStore\Connections ConnectionString $null
   Set-ItemProperty -Path HKLM:\SOFTWARE\Citrix\XDservices\ConfigurationSchema\DataStore\Connections ConnectionString $null
   Set-ItemProperty -Path HKLM:\SOFTWARE\Citrix\XDservices\DAS\DataStore\Connections ConnectionString $null
   Set-ItemProperty -Path HKLM:\SOFTWARE\Citrix\XDservices\DesktopUpdateManagerSchema\DataStore\Connections ConnectionString $null
   Set-ItemProperty -Path HKLM:\SOFTWARE\Citrix\XDservices\EnvTestServiceSchema\DataStore\Connections ConnectionString $null
   Set-ItemProperty -Path HKLM:\SOFTWARE\Citrix\XDservices\HostingUnitServiceSchema\DataStore\Connections ConnectionString $null
   Set-ItemProperty -Path HKLM:\SOFTWARE\Citrix\XDservices\Monitor\DataStore\Connections ConnectionString $null
   Set-ItemProperty -Path HKLM:\SOFTWARE\Citrix\XDservices\OrchestrationSchema\DataStore\Connections ConnectionString $null
   Set-ItemProperty -Path HKLM:\SOFTWARE\Citrix\XDservices\StorefrontSchema\DataStore\Connections ConnectionString $null
   Set-ItemProperty -Path HKLM:\SOFTWARE\Citrix\XDservices\TrustSchema\DataStore\Connections ConnectionString $null

2. 重啟DDC
3. DDC上重置connection string, 服務器地址請自行修改，保存ps1文件DDC上通過Powershell執行

Asnp citrix*

$cslog="Server=DB.ctx.com;Failover Partner=DB2.ctx.com;Initial Catalog=CitrixLogging;Integrated Security=True"
$csmonitor="Server=DB.ctx.com;Failover Partner=DB2.ctx.com;Initial Catalog=CitrixMonitoring;Integrated Security=True"

Set-ItemProperty -Path HKLM:\SOFTWARE\Citrix\DesktopServer\DataStore\Connections\Controller ConnectionString $cs

Set-ItemProperty -Path HKLM:\SOFTWARE\Citrix\XDservices\TrustSchema\DataStore\Connections ConnectionString $cs

Set-MonitorDBConnection -datastore Monitor -DBConnection $null
Set-MonitorDBConnection -datastore Monitor -DBConnection $csmonitor
Set-LogDBConnection -datastore Logging -DBConnection $null
Set-LogDBConnection -datastore Logging -DBConnection $cslog

4. 重啟DDC
5. 如果DDC多臺則需要分別修改
