Common client to transfer data from 2 oracle versions to SQL Server 2005

Hi,
I have two database servers on different machines. They are
1) Oracle 8.1.7.4
2) Oracle 7.3.1.4
I have to create agents which can transfer tables from these two databases to one machine having sql server 2005 database.

Please tell me what are the options. What drivers i need to install on machine having sql server 2005 so that i can transfer data from both oracle versions.

Thanks
Rajneesh.

You can use SQL Server SSIS to transfer data from Oracle to SQL. You need to install Oracle 8i client in the machine running SQL client.
