Hello.  Question for those familiar with running linked servers between Oracle to SQL Server.  How reliable and or efficient is the Oracle to SQL Server linked server connection using the "Microsoft OLE DB Provider for Oracle" data source?  

I ask because I'm not familiar with Oracle but have a project that will require connecting SQL Server to an Oracle db.  I've worked with numerous ODBC drivers via linked servers for other non-Oracle databases and have experienced very mixed results, particularly where queries become complex.  Anyone with experience on this please chime in.

Thanks.

Can you kindly clarify whether you are trying to create

* Linked Server from SQL Server to Oracle
* DB Link from Oracle to SQL Server

In both cases, you need to be more careful in the following cases:

1. Large Transactions
2. Running Resource intensive queries
3. Working with huge data in SELECT statements

On SQL Server, a linked server for oracle is what we are using in our project. Daily a lot of data is fetched from oracle without any issue. The linked servers are completely efficient and reliable.
