TL;DR; Provides code to retrieve the last processed date of cubes on an Analysis Services server, highlighting performance considerations and error handling in .NET environments.
I need a little bit of code to get the last processed date for the cube that my site connects to:
1Public Function GetCubeLastProcessedDates(ByVal AnalysisServer As String) As Collection(Of CubeInfo)
2 Dim result As Collection(Of CubeInfo)
3 Dim identity As WindowsIdentity = WindowsIdentity.GetCurrent()
4 Dim eCode As Integer = CommonUtility.RevertToSelf()
5 Dim oServer As New Server
6 Try
7 result = New Collection(Of CubeInfo)
8 oServer.Connect(String.Format(CultureInfo.InvariantCulture, "data Source = {0};", AnalysisServer))
9
10 For Each d As Database In oServer.Databases
11 For Each c As Cube In d.Cubes
12 result.Add(New CubeInfo(d.Name, c.Name, c.LastProcessed))
13 Next
14 Next
15
16 oServer.Disconnect()
17 Catch e As ConnectionException
18 ' Do some error handling
19 Catch e As AdomdErrorResponseException
20 ' Do some error handling
21 Catch e As AdomdConnectionException
22 ' Do some error handling
23 Catch e As Microsoft.AnalysisServices.AmoException
24 ' Do some error handling
25 Catch e As Exception
26 Throw
27 Finally
28 oServer.Dispose()
29 identity.Impersonate()
30 End Try
31 '------------------------------
32 Return result
33End Function
The only problem I have with this is that while it takes no longer than 5 seconds to return a negative result, it can take as much as 30 seconds to return when in the positive (i.e. you can access the cube).
This makes it a threading only, and more than that, a nice to have only. If this is critical information then you will just have to wait…
