I've been trying to access data in Oracle from SSIS via OLE DB and was getting the following warning:
"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."
Set AlwaysUseDefaultCodePage=TRUE on the OLE DB Source component that shows the warning and it will work fine
