.net – Oracle connection string without tnsnames.ora file


I am using the .NET framework with the System.Data.OracleClient namespace. I have the oracle 11 client installed on my computer. I do not want to use the tnsnames.ora file to store connection information.

Could someone please tell me what the connection string would look like if I did not want to use the tnsnames.ora file? I will be storing the connection string in a web.config file of a Web Application Project.

Starting with 10g clients, you can use the EZCONNECT feature, which does not require to edit the TNSNAMES.ORA file : username/password@servername:port/instance. For instance :

Data Source=localhost:1521/XE;Persist Security Info=True;User ID=scott;Password=tiger;Unicode=True
