Get SSAS Database Properties with PowerShell and AMO

December 17, 2008

Part I of this article series “Microsoft Windows PowerShell and SQL Server 2008 AMO” illustrated how to install Windows PowerShell and connect to an Analysis Service Servername. Part II illustrated how to use Windows PowerShell and AMO to get the various Server properties of SQL Server Analysis Service. Part III of this article discusses how to use Windows PowerShell and AMO to get the database properties of SQL Server Analysis Service.

Let us connect to Analysis Server using Windows PowerShell using AMO and get some information about one Database as shown below.

[System.Reflection.Assembly]::LoadWithPartialName
 ("Microsoft.AnalysisServices") >$NULL
$server = New-Object Microsoft.AnalysisServices.Server
$server.connect("PowerServer3\SQL2008")
$DBID = "Adventure Works DW 2008"
$database = $server.Databases.Item($DBID)

Note: PowerServer3 is the Analysis Server with named instance SQL2008. Please replace the server name with the Analysis server name in your environment. Please replace the database name with the actual database name on the Analysis server on your environment.

Now let us query all of the Methods available for the databases Class in ‘Microsoft AnalysisService.Server’. This can be achieved by using the Windows PowerShell cmdlet “get-member” with the parameter “ –membertype methods” as shown below.

$database |get-member -membertype methods

This displays a result similar to the results shown below. [Refer Figure 1.1]

Partial Result:

Backup
CanProcess
Clone
CopyTo
CreateObjRef
Detach
Dispose
Drop
Equals
GetDependents
GetHashCode
GetLifetimeService
GetReferences
GetType
GetUpdateOverwrites
InitializeLifetimeService
LinkDimension
Process
Refresh
Submit
ToString
Update
Validate

results of querying all of the Methods available for the databases Class in 'Microsoft AnalysisService.Server'
Figure 1.1

Now let’s query all the properties available for the database Class in ‘Microsoft AnalysisService.Server’. This can be achieved using Windows Powershell cmdlet “get-member” with parameter “ –membertype Properties”.

$database |get-member -membertype properties

This would display results similar to those shown below. [Refer Figure 1.2]

Query some of the SQL Server Analysis Service properties by using Windows PowerShell cmdlets:

$database.Name
$database.Roles | select name, members
$database.lastprocessed
$database.cubes |select name
$database.cubes |select name

The output is similar to the results shown below. [Refer Figure 1.3]

PS C:\AMOScripts> $database.Name
Adventure Works DW 2008
PS C:\AMOScripts> $database.Roles | select name, members
Name                                    Members
----                                    -------
SSASAdmin                               {POWERSERVER3\SSASUser}
SSASUser                                {SSASUser}

PS C:\AMOScripts> $database.lastprocessed

PS C:\AMOScripts> $database.cubes |select name
Name

Adventure Works
Mined Customers

PS C:\AMOScripts> $database.cubes |select name
Name
----
Adventure Works
Mined Customers

Now let’s create a Windows PowerShell script that displays some of the database properties of any SQL Server Analysis server and database that we pass as parameter.

Create a file, C:\AMOScripts\get-SSASDBproperty.ps1, using notepad and copy and paste the below code to that file and save it. [Refer Figure 1.4]

#Objective: To get database properties of the given Analysis Server 
#Created by: MAK
#Create Date: 9/9/2007
param
([string] $Servername, [string] $databasename)
## Add the AMO namespace
[Reflection.Assembly]::LoadWithPartialName("Microsoft.AnalysisServices") >$NULL
$server = New-Object Microsoft.AnalysisServices.Server
$server.connect($ServerName) 
if ($server.name -eq $null) {
 Write-Output ("Server '{0}' not found" -f $ServerName)
 break
}
else
{
$database = $server.Databases.Item($databasename)
if ($database.name -eq $null -or $database.name -eq "")
{
 Write-host "Database " $databasename " not found on the server $Servername"
 break
}
else
{
write-host "Server Name = " $Server.name
write-host "Database Name = " $database.Name
write-host "Database Last Schema Update = " $database.LastSchemaUpdate
write-host "Database Last Schema Update = " $database.LastProcessed
write-host "Database Cubes = " $database.cubes |select name
write-host "Database Dimensions = " $database.Dimensions | select name
}
}

Please copy the script from here. [Please provide link to get-ssasDBproperty.ps1.txt]

get-ssasDBproperty.ps1
Figure 1.4

Execute the get-ssasproperty.ps1 by passing the SQL Server 2005 Analysis server name as shown below. [Refer Figure 1.5]

set-location C:\AMOScripts
./get-ssasDBproperty.ps1 "BUS-INTEL" "Adventure Works DW"

Note: BUS-INTEL is the SQL Server 2005 Analysis Server with default Analysis Service instance. “Adventure Works DW” is the database name. Please replace the server name with the Analysis server name and the database name with your database name on your Analysis server in your environment.

Result

Server Name =  BUS-INTEL
Database Name =  Adventure Works DW
Database Last Schema Update =  11/22/2008 1:03:23 AM
Database Last Schema Update =  11/22/2008 1:42:33 AM

Connect to a SQL Server 2008 Analysis Server as shown below. [Refer Figure 1.6]

./get-ssasDBproperty.ps1 "PowerServer3\SQL2008" "Adventure Works DW 2008"

Note: PowerServer3 is the SQL Server Analysis Server with named instance SQL2008. Please replace the server name with the Analysis server name in your environment. Please replace the database name with your database name in your Analysis Server.

Result

Server Name =  POWERSERVER3\SQL2008
Database Name =  Adventure Works DW 2008
Database Last Schema Update =  11/30/2008 10:00:45 AM
Database Last Schema Update =  11/30/2008 10:03:15 AM

Connect to a SQL Server 2008 Analysis Server
Figure 1.6

Execute the Windows PowerShell script by passing a server name that is not available on the network and also passing a database name not available on the Analysis Server, you get an error message similar to the results below. [Refer Figure 1.7]

./get-ssasDBproperty.ps1 "ABC123"  "Adventure Works"
./get-ssasDBproperty.ps1 "BUS-INTEL"  "Adventure Works"

Result

Exception calling "Connect" with "1" argument(s): "A connection cannot be made.
 Ensure that the server is running."
At C:\AMOScripts\get-SSASDBproperty.ps1:12 char:16
+ $server.connect <<<< ($ServerName)

PS C:\AMOScripts> ./get-ssasDBproperty.ps1 "BUS-INTEL"  "Adventure Works"
Exception getting "Item": "Exception calling "get_Item" with "1" argument(s): "
