It has been a couple of years since I worked with Oracle within SSIS and I seem to recall having preferred the Oracle OLEDB Provider over Microsoft's OLEDB Provider for Oracle.
Does anyone have any preferences? What are the pros & cons? I'm looking for speed.
To use the Oracle Provider you have to download the Oracle Client and perform an Administrative Installation.
Any thoughts, ideas or suggestions?

definitely you'll need to use the Oracle driver, and not the microsoft driver;

besides there not being a 64 bit version of the MSDAORA driver, there are a few other issues as well; that driver was last updated for Oracle Version 8, so

no TNS support.

I seem to rem3ember there being an issue with LCOBS/BLOBS being handled differently,a nd the provider having issues, but i'd have to gooogle that;

like you, it's been a while since i fiddled with Oracle and the MSDAORA; we swiched to the oracle provider a long time ago.

Hey Lowell,

Thanks a lot.

Now I'm trying to remember which Oracle Download that I need. The Client Drivers only, etc?

I'm not sure and I would prefer to download the correct on on the first attempt.

I downloaded the Oracle Database 11g Release 2 Client (11.2.0.1.0) for Microsoft Windows (x64) from the following URL and the zip file was no good.

http://www.oracle.com/technetwork/database/enterprise-edition/downloads/112010-win64soft-094461.html

Thanks.

If my memory serves me right I think you need both 32- and 64-bit Oracle Client. If you're using BIDS (32-bit)you need 32-bit client to connect to the Oracle database. And a 64-bit client if SSIS is executed by SQL Server Agent (if you're running 64-bit SQL Server).

Yes, I'm running SQL Server 2008 R2 64 bit on Windows 2008 R2 64 bit.

I believe that you are right that I will need both 32 & 64 bit clients.

What alternative?

One Alternative to an OLEDB Source & Destination would be to setup a Linked Server and use OPENQURY.

I prefer to specify the Fast Load Option and uncheck Check Constraints on the OLEDB Destination to minimize the load time.

I found that the Installation for the Oracle10g Provider for OLE DB is probably what I need.

The download is at the following location:

http://www.oracle.com/technetwork/database/windows/utilsoft-088126.html

I run the install and I get the following error:

Oracle Universal Installer: The value of the environmental variable path is more than 1023 characters. This value cannot be set.

Looking for a solution to he

Check the path of the Environment Varible,if the path does not contain $oracle_home,such as d:oracleora81bin,you will get the error above.Just set the path manully,do check in the DOS command,type path:,if you see the $oracle_home is in the path it lists,then it'll be

The only reference I have is my own experience. First I installed a 64-bit Oracle client on a 64-bit SQL Server 2008. The developers using BIDS were unable to logon to the Oracle database. Installing a 32-bit Oracle client also enabled them to access the Oracle database.

I found an article that confirms that the 64 and 32 bit Oracle Client must be installed.
