Windows PowerShell-Skripts
Dieses Thema enthält Windows PowerShell Skripts, die auf den Computern in einer BizTalk Server Umgebung ausgeführt werden können, um Registrierungseinstellungen anzuwenden, die in diesem Handbuch beschrieben sind.
Wichtig
Diese Skripts sollten nur unter Windows Server 2003 und nicht unter Windows Server 2008 SP2 ausgeführt werden. Obwohl diese Skripts unter Windows Server 2008 SP2 erfolgreich ausgeführt werden, haben Labtests gezeigt, dass diese Skripts keinen signifikanten Leistungsvorteil unter Windows Server 2008 SP2 bieten. Diese Skripts sollten nur in einer Windows Server 2003-Produktionsumgebung nach eingehenden Tests und Auswertungen ausgeführt werden.
Optimieren der Betriebssystemleistung durch Registrierungseinstellungen
Das folgende Windows PowerShell Skript kann verwendet werden, um die Registrierungseinstellungen anzuwenden, die unter Optimieren der Betriebssystemleistung beschrieben sind.
Kopieren Sie das folgende Skript in Editor, und speichern Sie es als Set-OSRegSettings.ps1. Führen Sie dann das Skript auf jedem Computer in der BizTalk Server Umgebung aus, indem Sie die Anweisungen unter Optimieren der Betriebssystemleistung befolgen:
#Set-OSRegSettings.ps1

"Usage: .\OSSettings.ps1 -RAMMb 2048 -NumCPU 2 -VolType 4"
"Valid VolType values are: 1(few files), 2 or 3(moderate files), 4(many files)"
