I am trying to get the connection string of a database datasource with the following script:
$Analysis_Server = New-Object Microsoft.AnalysisServices.Server
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?
