Connect to Oracle by using Kerberos (JDBC Thin Driver)
This tutorial does not cover the configuration of Windows Server and Oracle instances. Consider reading the official documentation of these vendors.
Before configuring the connection in DataGrip, ensure that you have configured and got the following prerequisites:
Configured Kerberos client to run
kinit. For more information about configuring and installing Kerberos, see the Kerberos documentation at web.mit.edu.
For more information about configuring the server side, consider reading the following links.
Oracle instance with Kerberos. The following links might be useful:
Windows Server with configured Active Directory authentication.
Kerberos installed and configured on your Windows Server machine. The following documentation might help you:
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
In the command prompt or in the terminal, run the following command:kinit oraclekrb
oraclekrb, use your username.
Enter a password for the username.
Create a data source
Open data source properties. You can open data source properties by using one of the following options:
In the Database Explorer ( ), click the Data Source Properties icon .
In the Data Sources and Drivers dialog, click the Add icon () and select Oracle.
From the Connection type list, select SID.
In the Host field, type the host address of your database.
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;
From the Driver list, select Thin.
From the Authentication list, select Kerberos.
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;
EncryptionKey: Key bytes cannot be null!
There are cases when the connection does not work with the Oracle driver 188.8.131.52. Try switching to other driver versions (for example, 184.108.40.206 or 220.127.116.11). For more information about changing the driver's version, see Change the driver version.
