we have a requirement to create a Cube where Fact data avialable in Oracle and Dimensional Data available in Teradata which Datawarehouse .  The got the issue when we try to keep Other Relational data source as secondary Data source in SSAS .

Please check the actual issue what we are facing when we have multiple datasources apart from Sql server .

http://surendrathotamsbiproffesional.blogspot.be/2014/10/ssas-teradata-error-errors-in-high.html


we performed the Fallowing tests to confirm .


Here are the tests


Test 1 : Single Data source   è  Teradata ( .net data provider for Teradata )   è  PASS


Test 2 : Double Data Source è Teradata ( .net data provider for Teradata )    as Primary and Sql server as Secondary è PASS


Test 3 : Double Data Source è Teradata ( .net data provider for Teradata )    as Primary and Oracle  as Secondary ( Tried with all possible oracle connectors) è Fail

                 NOTE : Oracle ( Oledb provider for Oracle ) is not even open in DSV . it is givng below screen shoot error  when we tried to create Dimension


Test 4 : Double Data Source è Oracle (Oledb provider for Oracle)    as Primary and SQL server   as Secondary è PASS


Test 5 : Double Data Source èOracle (Oledb provider for Oracle)    as Primary and Teradata( .net data provider for Teradata )      as Secondary   è Fail





Conclusion : what we understand from  these tests are    Teradata Or Oracle can only be PRIMARY datasource .    OR Any body tried with Teradata and Oracle?????????

SSAS : A connection cannot be made to redirector. Ensure that 'SQL Browser' service is running. (Microsoft.AnalysisServices.AdomdClient). + Solution

Problem : have installed Analysis service on my server machine through remote login from my service account. I am able to open Analysis services from there. When I open SSMS from the same service account on my local machine, I am not able to connect to that Analysis service. It is giving me error by saying : "A connection cannot be made to redirector. Ensure that 'SQL Browser' service is running. (Microsoft.AnalysisServices.AdomdClient). A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connection host has failed to respond 10.245.192.111:2382(System)." Solution : Based on my research, the issue was caused by the Browser Service account was changed to the domain account. In your scenario, you can try to connect to the Analysis Service using <Servername>:2383 instead of instance name. Or you can change the Browser Service account to "Local System".

SSIS Error : Unable to infer the XSD from the XML file. The XML contains multiple namespaces

Problem : When we have Multiple Namespaces in the Xml Source which we need to load the Data from   as we shown below Then we will face a issue in generating XSD for that XML Error : Unable to infer the XSD from the XML file. The XML contains multiple namespaces. (Microsoft Visual Studio) Solution : First we need to avoid multiple namespaces to transform your source file to a format that doesn’t refer to the namespaces. SSIS has an XML task that can do the transformation. 1) Add the XML task to an SSIS   Control Flow and edit it. 2) Change the OperationType property value to XSLT, the SourceType to File connection and the Source to your source file that has the problem. 3) Set the SaveOperationResult property to True and expand the OperationResult branch. Set DestinationType to File Connection and the Destination to a new XML file ( ModifiedInput.XML). 4) Add the below script to a new file and save it with an xslt file extension (Input.XSLT) <
