Multisource universe problem with SQL Server

[Former Member]

Hi experts!

I have built a multisource universe over a SQL Server 2008 server (I´ll add other sources later). The connection is an OLEDB using the native client 11.

The problem is that, randomly, when trying to refresh a report I get a Data Federator error. Due to that, I´ve noticed that the Adaptative Processing server restarts.

I have seen in some forums that a possible solution is to use an ODBC connection instead. I create an ODBC 32 bits connection in windows, then an IDT secured connection. Up until here all good.

When I create a data foundation using that connection, I get the following exception:

[Microsoft][ODBC Driver Manager] The specified DSN contains an architecture missmatch between the Driver and Application

Any ideas for any of the two problems?

Many thanks,

Sergio

Hello Sergio,

Architecture mismatch means that you need to create ODBC 64 bit connection because your application is running on a 64 bit system architecture.

Hi Bayrem,

Thanks for your reply. Any ODBC driver I try -32 or 64 bits- raises the same error when I create the data foundation multisource. If I use oledb, it´s ok at this point (It fails later when refreshing reports).

With the same ODBC connection, a single source data foundation works ok.

Hi Sergio,

Create 32 bit DSN on Client machine(IDT) and 64 bit DSN on Server Machine(BO Server) with same Name.

If you have clustered environment then create 64 bit DSN with same name on all Nodes.

Hi Joyeb,

Thanks for you answer.

It was easier than that. I think the problem I was facing was that I was using a DSN with the SQL Server native client instead of the ODBC SQL Server driver.

Once I setup my ODBC DSN in 64 bits in the server I was able to refresh the data foundation.

Besides, it seems that the problem with the OLEDB driver are now solved, so I am now able to work with the multisource universe.

Thanks!
