DSC 环境资源在 WMF5.1 之后不再工作 - 未检测到 PATH 值？

  • 772

我有许多使用环境资源设置路径值的部分 DSC 脚本。我有两个执行此操作的脚本，从 WMF5.0 升级到 WMF5.1 后，启动 DscConfigurations 时出现以下错误。

VERBOSE: Perform operation 'Invoke CimMethod' with following parameters, ''methodName' = ApplyConfiguration,'className' = MSFT_DSCLocalConfigurationManager,'namespaceName' = root/Microsoft/Windows/DesiredStateConfiguration'.
VERBOSE: An LCM method call arrived from computer MYCOMPUTER with user sid S-1-5-21-1064954374-356710528-937385128-34335.
VERBOSE: [DESTCOMPUTER]:                            [] Starting consistency engine.
The resources ('[Environment]SetInstantClientPath' and '[Environment]SqlCmdPath') have conflicting values of the following properties: 'Value'. Ensure that their values match.  Merging of partial configurations failed. LCM 
failed to start desired state configuration manually.
    + CategoryInfo          : ResourceExists: (root/Microsoft/...gurationManager:String) [], CimException
    + FullyQualifiedErrorId : MI RESULT 11
    + PSComputerName        : DESTCOMPUTER

一个脚本执行此操作：

Environment SqlCmdPath {
    Name = "Path"
    DependsOn = "[Package]InstallSQLServer2012CmdLineUtils_64bit"
    Ensure = "Present"
    Path = $true
    Value = "$env:ProgramFiles\Microsoft SQL Server\110\Tools\Binn"
}

另一个脚本执行此操作：

Environment SetInstantClientPath {
    Name = "Path"
    DependsOn = "[Archive]InstallInstantClientBasic","[Archive]InstallInstantClientSqlplus"
    Ensure = "Present"
    Path = $true
    Value = "$env:SystemDrive\instantclient_11_2"
}

这曾经从 WMF5.0 愉快地运行

自 WMF5.1 以来有什么变化吗？

    您有两个具有相同名称参数值的环境资源（变量）。当引擎开始创建环境变量时，这可能会导致冲突。我建议你改成这样：

    Environment SqlCmdPath {
    Name = "SqlCmdPath"
    DependsOn = "[Package]InstallSQLServer2012CmdLineUtils_64bit"
    Ensure = "Present"
    Path = $true
    Value = "$env:ProgramFiles\Microsoft SQL Server\110\Tools\Binn"
}
Environment SetInstantClientPath {
    Name = "SetInstantClientPath"
    DependsOn = "[Archive]InstallInstantClientBasic","[Archive]InstallInstantClientSqlplus"
    Ensure = "Present"
    Path = $true
    Value = "$env:SystemDrive\instantclient_11_2"
}

    只是一个快速更新，但目前 MSFT 有一个关于这个确切问题的请求......
