SSAS 仅以编程方式备份​​元数据

我们有一组 SSAS 2005 数据库,由不同的员工维护。包括格式字符串等的元数据/模式已经发展到代表大量的工作,并且它们会定期更改。我们尝试过将商业智能项目置于源代码控制之下,但最好每晚备份所有 SSAS 元数据,而不需要数据本身。 (数据当然是巨大且可重复的,而架构很小。)

我可以使用 Microsoft.AnalysisServices.Server.Databases 集合以编程方式(C#)轻松循环遍历所有 SSAS 数据库,但我还没有找到一种简单的方法备份没有数据的架构。使用 SSMS,我可以右键单击数据库并选择 [Script Database as]-->[CREATE To]-->[File ...] 例如,并获取表示整个数据库元数据的 XMLA。此处引用:http://msdn.microsoft.com/en-us/ Library/ms174589.aspx,我相信这包含了我们想要备份的所有信息...但是我还没有在 Microsoft.AnalysisServices 程序集中找到提供类似功能的方法,并且不确定其他地方看看。

We have a set of SSAS 2005 databases that are maintained by various employees. The metadata/schema including format strings, etc. have evolved to represent a significant amount of work and they change periodically. We've tried having the business intelligence projects under source control, but it would also be nice to have a nightly backup of all SSAS metadata, without the data itself. (The data is of course huge and reproducible, whereas the schema is tiny.)

I can programmatically (C#) loop through all the SSAS dbs easily with the Microsoft.AnalysisServices.Server.Databases collection, but I haven't found a simple way to back up the schema without the data. Using SSMS, I can right-click the db and choose [Script Database as]-->[CREATE To]-->[File ...] for example and get XMLA representing the entire database metadata. This is referenced here: http://msdn.microsoft.com/en-us/library/ms174589.aspx, and I believe this has all the information we'd like to back up... however I haven't found methods providing similar functionality in the Microsoft.AnalysisServices assembly and am not sure where else to look.

我知道我可能有点晚了,但事情就这样了..

这是 PowerShell,但转换为 C# 很容易:

$svrName = "localhost\sql08"
$sourceDB = "Adventure Works DW 2008"
$sourceCube = "Adventure Works"

# load the AMO library (redirect to null to 'eat' the output from assembly loading process)
[System.Reflection.Assembly]::LoadwithpartialName("Microsoft.AnalysisServices") > $null
# connect to the AS Server
$svr = New-Object Microsoft.AnalysisServices.Server
$svr.Connect($svrName)

# get a reference to the database
$db= $svr.Databases.Item($sourceDB)
# get a reference to the cube
$cub = $db.Cubes.FindByName($sourceCube)

# setup the scripter object
$sb = new-Object System.Text.StringBuilder
$sw = new-Object System.IO.StringWriter($sb)
$xmlOut = New-Object System.Xml.XmlTextWriter($sw) 
$xmlOut.Formatting = [System.Xml.Formatting]::Indented
$scr = New-Object Microsoft.AnalysisServices.Scripter

# create an array of MajorObjects to pass to the scripter
$x = [Microsoft.AnalysisServices.MajorObject[]] @($cub)

$scr.ScriptCreate($x,$xmlOut,$false)

$sb.ToString() > c:\data\tmpCube2.xmla

# clean up any disposeable objects
$sw.Close()
$svr.Disconnect()
$svr.Dispose()

这不是我的,我发现了它 此处 其中 达伦·戈斯贝尔发布了它。

I know I may be kind of late, but here it goes..

This is PowerShell, but converting to C# is a breeze:

$svrName = "localhost\sql08"
$sourceDB = "Adventure Works DW 2008"
$sourceCube = "Adventure Works"

# load the AMO library (redirect to null to 'eat' the output from assembly loading process)
[System.Reflection.Assembly]::LoadwithpartialName("Microsoft.AnalysisServices") > $null
# connect to the AS Server
$svr = New-Object Microsoft.AnalysisServices.Server
$svr.Connect($svrName)

# get a reference to the database
$db= $svr.Databases.Item($sourceDB)
# get a reference to the cube
$cub = $db.Cubes.FindByName($sourceCube)

# setup the scripter object
$sb = new-Object System.Text.StringBuilder
$sw = new-Object System.IO.StringWriter($sb)
$xmlOut = New-Object System.Xml.XmlTextWriter($sw) 
$xmlOut.Formatting = [System.Xml.Formatting]::Indented
$scr = New-Object Microsoft.AnalysisServices.Scripter

# create an array of MajorObjects to pass to the scripter
$x = [Microsoft.AnalysisServices.MajorObject[]] @($cub)

$scr.ScriptCreate($x,$xmlOut,$false)

$sb.ToString() > c:\data\tmpCube2.xmla

# clean up any disposeable objects
$sw.Close()
$svr.Disconnect()
$svr.Dispose()

It's not mine, I found it here where Darren Gosbell posted it.

我找到了解决方案:

void ScriptDb(string svrName, string dbName, string outFolderPath)
{
  using (var svr = new Server())
  {
    svr.Connect(svrName);

    // get a reference to the database
    var db = svr.Databases[dbName];

    // setup the scripter object
    var sw = new StringWriter();
    var xmlOut = new XmlTextWriter(sw);
    xmlOut.Formatting = Formatting.Indented;
    var scr = new Scripter();

    // create an array of MajorObjects to pass to the scripter
    var x = new MajorObject[] { db };
    scr.ScriptCreate(x, xmlOut, true);

    // todo: would be wise to replace illegal filesystem chars in dbName
    var outPath = Path.Combine(outFolderPath, dbName + ".xmla");
    File.WriteAllText(outPath, sw.ToString());

    // clean up any disposeable objects
    sw.Close();
    svr.Disconnect();
    svr.Dispose();
  }
}

I've found a solution:

void ScriptDb(string svrName, string dbName, string outFolderPath)
{
  using (var svr = new Server())
  {
    svr.Connect(svrName);

    // get a reference to the database
    var db = svr.Databases[dbName];

    // setup the scripter object
    var sw = new StringWriter();
    var xmlOut = new XmlTextWriter(sw);
    xmlOut.Formatting = Formatting.Indented;
    var scr = new Scripter();

    // create an array of MajorObjects to pass to the scripter
    var x = new MajorObject[] { db };
    scr.ScriptCreate(x, xmlOut, true);

    // todo: would be wise to replace illegal filesystem chars in dbName
    var outPath = Path.Combine(outFolderPath, dbName + ".xmla");
    File.WriteAllText(outPath, sw.ToString());

    // clean up any disposeable objects
    sw.Close();
    svr.Disconnect();
    svr.Dispose();
  }
}
