Windows PowerShell 脚本
本主题包含可在BizTalk Server环境中的计算机上运行的Windows PowerShell脚本，以应用本指南中所述的注册表设置。
重要
这些脚本只能在 Windows Server 2003 上运行，而不能在 Windows Server 2008 SP2 上运行。 虽然这些脚本将在 Windows Server 2008 SP2 上成功执行，但实验室测试表明，这些脚本在 Windows Server 2008 SP2 上没有任何明显的性能优势。 这些脚本应仅在经过彻底测试和评估后在 Windows Server 2003 生产环境中运行。
通过注册表设置优化操作系统性能
以下Windows PowerShell脚本可用于应用优化操作系统性能中所述的注册表设置。
将以下脚本复制到记事本中，并另存为 Set-OSRegSettings.ps1。 然后按照优化操作系统性能中的说明，在BizTalk Server环境中的每台计算机上运行该脚本：
#Set-OSRegSettings.ps1
param($RAMMb, $NumCPU,$VolType)
if (($RAMMb -eq $null) -or ($NumCPU -eq $null) -or ($VolType -eq $null) -or ($VolType -gt 4))
{
"`r"
"Please specify required paramemters of -RAMMb and -NumCPU and -VolType"
"Usage: .\OSSettings.ps1 -RAMMb 2048 -NumCPU 2 -VolType 4"
"Valid VolType values are: 1(few files), 2 or 3(moderate files), 4(many files)"
"`r"
exit
