Creating SSAS 2008 cube partitions using Powershell? - powershell

Question

How can we create SSAS 2008 cube partitions using Powershell?

Answer 1

This adds a partition to the Adventure Works DW 2008R2 cube (specifically the Internet Customers measure group in the Adventure Works cube):
$server_name = "localhost"
$catalog = "Adventure Works DW 2008R2"
$cube = "Adventure Works"
$measure_group = "Fact Internet Sales"
$old_partition = "Customers_2004"
$new_partition = "Customers_2009"
$old_text = "'2008"
$new_text = "'2009"
[Reflection.Assembly]::LoadFile("C:\Program Files\Microsoft SQL Server\100\SDK\Assemblies\Microsoft.AnalysisServices.DLL")
$srv = new-object Microsoft.AnalysisServices.Server
$srv.Connect("Data Source=" + $server_name)
$new_part = $srv.Databases[$catalog].Cubes[$cube].MeasureGroups[$measure_group].Partitions[$old_partition].Clone()
$new_part.ID = $new_partition
$new_part.Name = $new_partition
$new_part.Source.QueryDefinition = $new_part.Source.QueryDefinition.Replace($old_text, $new_text)
$srv.Databases[$catalog].Cubes[$cube].MeasureGroups[$measure_group].Partitions.Add($new_part)
$srv.Databases[$catalog].Cubes[$cube].MeasureGroups[$measure_group].Partitions[$new_partition].Update()
$srv.Databases[$catalog].Update()
$srv.Disconnect()
You'll have to change variables up top, and the reference to the Microsoft.AnalysisServices.dll assembly, but other than that, this will work peachy keen.
The trick is to call Update() on the object changed and then on the whole database itself.
If you'd like to process the new partition, as well, you can do that with the following line before $srv.Disconnect:
$srv.Databases[$catalog].Cubes[$cube].MeasureGroups[$measure_group].Partitions[$new_partition].Process()

Answer 2

Check out this: PowerSSAS
It doesn't have explicit add partition support, so you'll probably have to craft an XMLA snippet to do the add partition and then use PowerSSAS to push it to the SSAS server.

Answer 3

you can use :
Microsoft.AnalysisServices.Deployment [ASdatabasefile]
{[/s[:logfile]] | [/a] | [[/o[:output_script_file]] [/d]]}
to deploy your cube AS with powershell.
