The linked servers on SQL Server stopped working Suddenly. Error message is below Cannot initialize the data source object of OLE DB provider "OraOLEDB.Oracle" for linked server "<name>". It used to happen once a week, we added a "timeout" to the Oracleprovider, since then, it is happening once every month or two. One of the known solution is a full SQL Server restart. But restartingthe SQL server is not a viable solution all the time because of theserver usage times. Any one has any idea why the Oracle driver may do this? And if there is any other known fix?
