Usage

To establish a connection to server you have to provide some connection parameters to dotConnect for Oracle. This information is used by the OracleConnection component to find the server and login with credentials of your account. The parameters are represented as connection string. You can compose the connection string manually or have dotConnect for Oracle construct it for you.

There are two ways to connect to server: with and without Oracle Client Interface. This is controlled by Direct property. It indicates whether the Oracle Client Interface will be used for connecting to server. By default Direct mode is disabled to preserve maximal functionality. Switch to Direct mode if you want to work in a system without Oracle Client Software installed.

This snippet directly configures a Oracle connection using a connection string.

using Devart.Data.Oracle;
...
OracleConnection oracleConnection = new OracleConnection();
oracleConnection.Server = "OraServer";
oracleConnection.UserId = "scott";
oracleConnection.Password = "tiger";
