I would expect the steps to translate to SQL 2008 and Oracle 11.2 unless the Oracle Drivers took a step backward.[u][url=http://www.mssqltips.com/sqlservertip/1433/how-to-setup-linked-servers-for-sql-server-and-oracle-64-bit-client/]http://www.mssqltips.com/sqlservertip/1433/how-to-setup-linked-servers-for-sql-server-and-oracle-64-bit-client/[/url][/u]Thu, 08 Nov 2012 23:20:53 GMTopc.threehttp://www.sqlservercentral.com/Forums/Topic1380973-391-1.aspxSorry, I am not sure why I mentioned it at all for since you are on 64-bit, I wasn't paying close attention and only picked up on "32" being discussed in a couple posts. MSDORA will not be available for you on 64-bit.Back to MSDASQL...have you tried creating a 64-bit ODBC DSN and referencing the DSN in your Linked Server? Creating the DSN will also allow you the chance to test the connection ahead of time, prior to attempting to use it with a Linked Server which may help you narrow down where the issue resides.Thu, 08 Nov 2012 23:16:05 GMTopc.threehttp://www.sqlservercentral.com/Forums/Topic1380973-391-1.aspxHi,I am not getting MSDORA in providers list while creating Linked server from SQL studio.I have successfully installed oracle instant client and able to connect from 32 bit application.OS is windows2008R2 and SQL Server is 2008 64 bit.
