ConnectionString property not printing connection string

Question

I am trying to get the connection string of a database datasource with the following script:

   $Analysis_Server = New-Object Microsoft.AnalysisServices.Server           


        

Answer 1

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

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.

Answer 2

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
     }
}

Answer 3

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?
