DataGrip 2024.1 Help

Create an Oracle data source using Kerberos and Thin driver

Official documentation and software

DataGrip uses JDBC drivers to connect to the Oracle server through the TNS protocol. The following driver modes are available:

  • In Thin mode, the JDBC driver always connects to the TNS listener. In this mode, various versions of the JDBC driver can be used.

  • In OCI mode, the JDBC driver uses native libraries. In this case, the JDBC driver's version must be the same as the version of these native libraries.


This tutorial does not cover the configuration of Windows Server and Oracle instances. Consider reading the official documentation of these vendors.

Client side

Before configuring the connection in DataGrip, ensure that you have configured and got the following prerequisites:

Server side

For more information about configuring the server side, refer to the following links.

Configuring data source in DataGrip

First, you need to obtain a ticket for a user. To obtain the ticket, you need to run the kinit command with the username.

Run kinit in the command prompt

  1. In the command prompt or in the terminal, run the following command:

    kinit oraclekrb

    Instead of oraclekrb, use your username.

  2. Enter a password for the username.

    kinit in the command prompt

Create a data source

  1. To connect to the database, create a data source that will store your connection details. You can do this using one of the following ways:

    • In the main menu, go to File | New | Data Source and select Oracle.

    • In the Database Explorer ( View | Tool Windows | Database Explorer) , click the New icon (the New icon) in the toolbar. Navigate to Data Source and select Oracle.

    Create a new data source
  2. From the Connection type list, select SID.

    Select the Connection type
  3. In the Host field, type the host address of your database.

  4. In the SID field, enter the instance name. You can ask your database administrator for the instance name or try running the following query in the command prompt when connected to the instance with your user:

    SELECT sys_context('userenv','instance_name') FROM dual;
  5. From the Driver list, select Thin.

    Select the Thin driver
  6. From the Authentication list, select Kerberos.

    Kerberos authentication type
  7. On the General tab, click Test Connection to ensure that the connection is successful.


Check an authentication method

  • Run the following query from the data editor:

    SELECT sys_context('userenv', 'authentication_method') FROM dual;
    Check a authentication method


EncryptionKey: Key bytes cannot be null!

There are cases when the connection does not work with the Oracle driver Try switching to other driver versions (for example, or For more information about changing the driver's version, refer to Change the driver version.
