移动和重命名 AppFabric 配置数据库

Question

最近我们对 AppFabric 配置数据库进行了移动和重命名。

重命名是从默认名称 "AppFabricConfigurationDatabase" 到 "AppFabricPreOrdersConfiguration"

DistirbutedCacheService.exe.config 已更改为新数据库和服务器名称

<clusterConfig provider="System.Data.SqlClient" connectionString="Data Source=NEWSERVER;Initial Catalog=AppFabricPreOrdersConfiguration;Integrated Security=True" />

服务启动成功。

但从此时起 "caching administration powershell" 不再启动，因为调用 use-cachecluster 时它仍会尝试连接到旧服务器/数据库。

ConnectionString Data Source=OLDSERVER 的测试连接失败；初始目录 =AppFabricCacheConfigurationDatabase;

Use-CacheCluster : ErrorCode:SubStatus:Invalid 提供者和 c 连接字符串读取。

powershell 从哪里读取这些值？显然不是来自服务的配置文件，而是来自哪里？

您需要调用 Remove-CacheAdmin and then Add-CacheAdmin 来更改每个管理主机上的缓存管理连接

This Microsoft Powershell script -（.EXE 下载，下面复制的脚本）- 更改集群中所有主机上的连接字符串。

param ([string] $provider, [string] $newConnectionString)

function Main {

    if ( (! $provider) -or (! $newConnectionString))
    {
        Write-Host "Usage: ChangeConnString.ps1 <provider> <newConnectionString>"
        exit(1)
    }

    Import-Module "DistributedCacheAdministration"
    Import-Module "DistributedCacheConfiguration"

    Use-CacheCluster

    Write-Host "Stop the cache cluster if it is running"
    $clusterRunnig=$true
    &{
        Stop-CacheCluster -EA Stop
    }
    trap [DataCacheException] {  
        #'Error Category {0}, Error Type {1}, ID: {2}, Message: {3} {4}' -f  $_.CategoryInfo.Category, $_.Exception.GetType().FullName,  $_.FullyQualifiedErrorID, $_.Exception.Message, $_.Exception.ErrorCode;
        #12008: ErrorCode<ERRCAdmin008>:SubStatus<ES0001>:No hosts running in cluster
        if ($_.Exception.ErrorCode -eq 12008)
        {
            write-host "Cluster is not running"
            $clusterRunnig=$false
            continue
        }
    }

    [Reflection.Assembly]::LoadWithPartialName('Microsoft.ApplicationServer.Caching.Management') | Out-Null
    [Reflection.Assembly]::LoadWithPartialName('System.Management.Automation') | Out-Null
    [Reflection.Assembly]::LoadWithPartialName('System.Management.Automation.Runspaces') | Out-Null

    SetCacheConnectionString $provider $newConnectionString

    Write-Host "Connection string is altered on all the cache hosts. Now changing the connection string for cache admin"
    Remove-CacheAdmin
    Add-CacheAdmin -Provider $provider -ConnectionString $newConnectionString

    if ($clusterRunnig -eq $true)
    {
        Write-Host "Starting the cache cluster..." 
        Start-CacheCluster
    }
}

function SetCacheConnectionString {

    param ([string] $provider, [string] $newConnectionString)

    Write-Host "Parameters: " $provider " " $newConnectionString
    $powerShell = [System.Management.Automation.PowerShell]::Create()
    # Import the admin cmdlets module
    $powerShell.AddCommand("Import-Module", $true);
    $powerShell.AddParameter("Name", "DistributedCacheAdministration")

    # Call the Invoke method to run the commands
    $powerShell.Invoke();

    $powerShell.Commands.AddCommand("Use-CacheCluster")
    $powerShell.Commands.AddCommand("Get-CacheHost")
    $commandResults = $powerShell.Invoke()
    $powerShell.Dispose()

    Write-Host "Number of hosts in the cluster " $commandResults.Count
    foreach ($cacheHost in $commandResults)
    {
        Write-Host "Configuring the host " $cacheHost.HostName

        Invoke-Command -ComputerName $cacheHost.HostName -ScriptBlock {param ($provider, $newConnectionString) Import-Module DistributedCacheConfiguration;Remove-CacheHost;Add-CacheHost -Provider $provider -ConnectionString $newConnectionString -Account 'NT Authority\NETWORK SERVICE'} -ArgumentList $provider, $newConnectionString
    }
}

因为我无法停止集群，所以我尝试查看连接字符串是否会在不重新启动的情况下被更改，基本上只是调用 Remove-CacheAdmin 和 Add-CacheAdmin ....它成功了！当然，脚本必须在每台主机上运行，因此不适合大型设置，但显然不需要重新启动

param ([string] $provider, [string] $newConnectionString)

function Main {

    if ( (! $provider) -or (! $newConnectionString))
    {
        Write-Host "Usage: ChangeConnString.ps1 <provider> <newConnectionString>"
        exit(1)
    }

    Import-Module "DistributedCacheAdministration"
    Import-Module "DistributedCacheConfiguration"
    [Reflection.Assembly]::LoadWithPartialName('Microsoft.ApplicationServer.Caching.Management') | Out-Null
    [Reflection.Assembly]::LoadWithPartialName('System.Management.Automation') | Out-Null
    [Reflection.Assembly]::LoadWithPartialName('System.Management.Automation.Runspaces') | Out-Null

    Remove-CacheAdmin
    Add-CacheAdmin -Provider $provider -ConnectionString $newConnectionString  

}

其他用户提供的脚本对我不起作用。我遇到了异常。我能够通过在每台主机上编辑注册表并重新启动服务来解决这个问题。

连接字符串存储在这里：HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\AppFabric\V1.0\Configuration

该值被命名为 "ConnectionString"

在用户配置单元下，还有另一个连接字符串实例。我不知道你是否需要改变这个，但我做到了。 HKEY_CURRENT_USER\Software\Microsoft\AppFabric\V1.0\Temp

这对我有用。不要忘记，您还需要编辑 C:\Program Files\AppFabric 1.1 下 DistributedCacheService.exe.config 中的 ClusterConfig ConnectionString for Windows Server
