问题:
I am trying to get the connection string of a database datasource with the following script:
$Analysis_Server = New-Object Microsoft.AnalysisServices.Server $Analysis_Server.connect("$server") $database = $Analysis_Server.Databases[7] $c = $database.DataSources[0].ConnectionString $c
nothing is outputting.
I have tried debugging like so:
$Analysis_Server.Databases
this prints out all databases on the server
if i index it $Analysis_Server.Databases[], it prints whatever database is indexed (so in my case, 7, prints database8)
clearly the Database property is working.
-------------UPDATE:--------------
here is how the Databases look in the server
here is what each of the following lines does:
$Analysis_Server.Databases
this prints out
One thing one can notice is for some reason they are printed out not in order of how they are on the analysis server as in the picture...I dont know why that is the case
this is what this command prints out:
Analysis_Server.Databases[0]
Now since index 0 worked, we should be able to index [1], [2], etc...
so the following
Analysis_Server.Databases[1] Analysis_Server.Databases[2]
prints:
Now unto the connection string:
$Analysis_Server.Databases[0].DataSources[0].ConnectionString
that prints out:
Connection Timeout=60;User Id=someID;Data Source=10.10.10.10;Persist Security Info=True
its appears to be the connection string for Database8
cool, so then we should be able to do this as well:
$Analysis_Server.Databases[1].DataSources[0].ConnectionString
However, nothing prints! the only index that seems to print is with Databases[0]
This is what $Analysis_Server.Databases[0].DataSources[0] prints:
we should be able to do the same for all databases
$Analysis_Server.Databases[1].DataSources[0]
$Analysis_Server.Databases[2].DataSources[0] etc..
but nothing gets printed!

I just played with things a little more, to make sure I understood the issue that you are facing. On the same box, still with the newest available SqlServer PowerShell module loaded - I get these results.
PS C:\Users\Administrator> $Analysis_Server = New-Object Microsoft.AnalysisServices.Server PS C:\Users\Administrator> $Analysis_Server.connect("AX2012R2A") PS C:\Users\Administrator> $Analysis_Server.Databases Name State Read-Write Mode ---- ----- --------------- Demand Forecast ps Processed ReadWrite Demand Forecast Accuracy ps Processed ReadWrite Demand Forecast Accuracy initial Processed ReadWrite Dynamics AX ps Processed ReadWrite Demand Forecast initial Processed ReadWrite Dynamics AX initial Processed ReadWrite
Now I traverse every database and their datasources, to display the connection string
PS C:\Users\Administrator> $Analysis_Server.Databases | ForEach-Object {$_.datasources} Name Isolation Max Connections Connection String ---- --------- --------------- ----------------- Dynamics Database ReadCommitted 10 Provider=SQLNCLI11.1;Data Source=AX2012R2A;Integrated Security=SSPI;Initial Catalog=DatabaseName_4 Dynamics Database ReadCommitted 10 Provider=SQLNCLI11.1;Data Source=AX2012R2A;Integrated Security=SSPI;Initial Catalog=DatabaseName_2 Dynamics Database ReadCommitted 10 Provider=SQLNCLI11.1;Data Source=AX2012R2A;Integrated Security=SSPI;Initial Catalog=DatabaseName_1 Dynamics Database ReadCommitted 10 Provider=SQLNCLI11.1;Data Source=AX2012R2A;Integrated Security=SSPI;Initial Catalog=DatabaseName_6 Dynamics Database ReadCommitted 10 Provider=SQLNCLI11.1;Data Source=AX2012R2A;Integrated Security=SSPI;Initial Catalog=DatabaseName_3 Dynamics Database ReadCommitted 10 Provider=SQLNCLI11.1;Data Source=AX2012R2A;Integrated Security=SSPI;Initial Catalog=DatabaseName_5
And the one-liner that just gives you the connection string and nothing else
PS C:\Users\Administrator> $Analysis_Server.Databases | ForEach-Object {$_.datasources | ForEach-Object {$_.ConnectionSt ring}} Provider=SQLNCLI11.1;Data Source=AX2012R2A;Integrated Security=SSPI;Initial Catalog=DatabaseName_4 Provider=SQLNCLI11.1;Data Source=AX2012R2A;Integrated Security=SSPI;Initial Catalog=DatabaseName_2 Provider=SQLNCLI11.1;Data Source=AX2012R2A;Integrated Security=SSPI;Initial Catalog=DatabaseName_1 Provider=SQLNCLI11.1;Data Source=AX2012R2A;Integrated Security=SSPI;Initial Catalog=DatabaseName_6 Provider=SQLNCLI11.1;Data Source=AX2012R2A;Integrated Security=SSPI;Initial Catalog=DatabaseName_3 Provider=SQLNCLI11.1;Data Source=AX2012R2A;Integrated Security=SSPI;Initial Catalog=DatabaseName_5
Could you take the time and try to install the latest SqlServer PowerShell module and see if that makes any difference for you and the problem that you are facing?

Not saying that I have an answer for you, but I think you can use another approach to get what you need, while waiting for Microsoft support.
I'm working on a AX 2012 demo system, that is running SQL Server 2014. It has several olap databases inside the same instance. I've edited all datasources to point to a different database, to show that we get the correct details out.
I installed the latest SQL Server PowerShell module while testing this.
Install-Module SqlServer -Force -Confirm:$false Import-Module SqlServer
Now you should have a new PowerShell provider, that enables you to traverse the SQL Server as was it a file system
Get-PSProvider Name Capabilities Drives ---- ------------ ------ Registry ShouldProcess, Transactions {HKLM, HKCU} Alias ShouldProcess {Alias} Environment ShouldProcess {Env} FileSystem Filter, ShouldProcess, Credentials {C, E, A, D...} Function ShouldProcess {Function} Variable ShouldProcess {Variable} SqlServer Credentials {SQLSERVER} Certificate ShouldProcess {Cert} WSMan Credentials {WSMan}
With that in our hand, you should be able to do the following, that should produce the correct results
#Connect to the SSAS part of the sql server PS C:\Users\Administrator> cd SQLSERVER:\SQLAS #List all local instances PS SQLSERVER:\SQLAS> dir Host Name --------- AX2012R2A HTTP_DS #Connect to the server (local) - you should be able to type in a valid network name PS SQLSERVER:\SQLAS> cd AX2012R2A #List all instances on that server PS SQLSERVER:\SQLAS\AX2012R2A> dir Instance Name ------------- DEFAULT POWERPIVOT TABULAR #Connect to the default instance on the server you are connected to PS SQLSERVER:\SQLAS\AX2012R2A> cd default #List all available collections / areas PS SQLSERVER:\SQLAS\AX2012R2A\default> dir #Connect to the databases area PS SQLSERVER:\SQLAS\AX2012R2A\default> cd databases #List all databases that are available PS SQLSERVER:\SQLAS\AX2012R2A\default\databases> dir Name State Read-Write Mode ---- ----- --------------- Demand Forecast Accuracy initial Processed ReadWrite Demand Forecast Accuracy ps Processed ReadWrite Demand Forecast initial Processed ReadWrite Demand Forecast ps Processed ReadWrite Dynamics AX initial Processed ReadWrite Dynamics AX ps Processed ReadWrite #Getting the same result with Get-ChildItem PS SQLSERVER:\SQLAS\AX2012R2A\default\databases> Get-ChildItem Name State Read-Write Mode ---- ----- --------------- Demand Forecast Accuracy initial Processed ReadWrite Demand Forecast Accuracy ps Processed ReadWrite Demand Forecast initial Processed ReadWrite Demand Forecast ps Processed ReadWrite Dynamics AX initial Processed ReadWrite Dynamics AX ps Processed ReadWrite #Traverse all databases and show their connection string details PS SQLSERVER:\SQLAS\AX2012R2A\default\databases> Get-ChildItem | ForEach-Object {$_.Datasources} Name Isolation Max Connections Connection String ---- --------- --------------- ----------------- Dynamics Database ReadCommitted 10 Provider=SQLNCLI11.1;Data Source=AX2012R2A;Integrated Security=SSPI;Initial Catalog=DatabaseName_1 Dynamics Database ReadCommitted 10 Provider=SQLNCLI11.1;Data Source=AX2012R2A;Integrated Security=SSPI;Initial Catalog=DatabaseName_2 Dynamics Database ReadCommitted 10 Provider=SQLNCLI11.1;Data Source=AX2012R2A;Integrated Security=SSPI;Initial Catalog=MicrosoftDynamicsAX Dynamics Database ReadCommitted 10 Provider=SQLNCLI11.1;Data Source=AX2012R2A;Integrated Security=SSPI;Initial Catalog=DatabaseName_4 Dynamics Database ReadCommitted 10 Provider=SQLNCLI11.1;Data Source=AX2012R2A;Integrated Security=SSPI;Initial Catalog=DatabaseName_5 Dynamics Database ReadCommitted 10 Provider=SQLNCLI11.1;Data Source=AX2012R2A;Integrated Security=SSPI;Initial Catalog=DatabaseName_6 PS SQLSERVER:\sqlas\ax2012r2A\default\databases> Get-ChildItem | ForEach-Object {$_.Datasources | ForEach-Object {$_.Connectionstring}} Provider=SQLNCLI11.1;Data Source=AX2012R2A;Integrated Security=SSPI;Initial Catalog=DatabaseName_1 Provider=SQLNCLI11.1;Data Source=AX2012R2A;Integrated Security=SSPI;Initial Catalog=DatabaseName_2 Provider=SQLNCLI11.1;Data Source=AX2012R2A;Integrated Security=SSPI;Initial Catalog=DatabaseName_3 Provider=SQLNCLI11.1;Data Source=AX2012R2A;Integrated Security=SSPI;Initial Catalog=DatabaseName_4 Provider=SQLNCLI11.1;Data Source=AX2012R2A;Integrated Security=SSPI;Initial Catalog=DatabaseName_5 Provider=SQLNCLI11.1;Data Source=AX2012R2A;Integrated Security=SSPI;Initial Catalog=DatabaseName_6
I would say that this should get you going, because you can now trust that you have the correct connection string details. I relation to your other question - this should give you all the details for the alter script that you want to produce, so you supply the entire alter statement as the SQL Server expects from you.

found this in a post here: http://www.mrtsql.com/2011/03/powershell-updating-analysis-services.html
See if this function in that post helps you out.
function UpdateDataSources() { # Lets get our server name $SSASServerName="$env:ComputerName\" + $SSASInstanceName $MyConnection = New-Object("Microsoft.AnalysisServices.Server") $MyConnection.Connect($SSASServerName) # lets return the number of data sources [int]$DataSourcecount=$MyConnection.Databases[$DatabaseName].DataSources.count for ($count=0; $count -ne $DataSourcecount;++$count) { $MyCS=$MyConnection.Databases[$DatabaseName].DataSources[$count].ConnectionString $NewCS=setNewValue -MyCS $MyCS -Pattern "Data Source=" -ReplaceWith $DataSourceServer if ($PW.Length -ne 0) { $NewCS=setNewValue -MyCS $NewCS -Pattern "Password=" -ReplaceWith $PW } if ($UserName.length -ne 0) { $NewCS=setNewValue -MyCS $NewCS -Pattern "User ID=" -ReplaceWith $UserName } $MyConnection.Databases[$DatabaseName].DataSources[$count].ConnectionString=$NewCS # write the change back to SSAS $MyConnection.Databases[$DatabaseName].DataSources[$count].update() write-output $NewCS } }
