CodePage error while importing data from Oracle to SQL Server using SSIS

I get th开发者_运维知识库e following warning on the OLEDB Source in the SSIS package.

Warning 1 Validation warning. Data Flow Task: {20582F6F-DD9C-45F5-8727-992F525E67DC}: Cannot retrieve the column code page info from the OLE DB provider. If the component supports the "DefaultCodePage" property, the code page from that property will be used. Change the value of the property if the current string code page values are incorrect. If the component does not support the property, the code page from the component's locale ID will be used.

After setting the AlwaysUseDefaultCoePage to true the warning disappears but 0 rows are transferred from source to destination. There is also no error shown.

Update: The oracle server uses the US7ASCII character set. I am unable to find the code page number for this character set.

Code page identifier for US-ASCII (7-bit) is 20127

You can find the list of all code page identifiers in the following link.
