AutoCompleteExtender oracle database using

I am not sure what issue you are getting for oracle. Since it is just a database for getting data. So if you create web method to retrieve data for Ajax AutoComplete, then modify your method to get data from Oracle instead of SQL.
Refer the below link for better under stand of retrieving data from DB to AutoCompleteExtender

Connect to ORACLE from ASP.NET refer the below link
