Connecting to Oracle databases

Table of contents

There are several ways to configure a database connection and several ways to perform an authentication.

Configuration types

Basic connections

Host/port based configuration

Parameter Description Example
Host Server host name 192.168.1.25
Post number Server listener port 1521 (default)
Database Service or SID name ORCL
Service/SID It depends on the server configuration.
SID must be selected for some servers and the Service Name for others 		SID

TNS

TNS configuration is the simplest, but it requires you to have the tnsnames.ora file somewhere on your disk. tnsnames.ora contains information about all accessible Oracle server connections. DBeaver can determine the default location of this file, but sometimes you will need to manually specify it.

Parameter Description Example
Network Alias Name of configuration from tnsnames.ora ORCL1
TNS names path Path to tnsnames.ora file.
By default, it is got from the TNS_ADMIN environment variable or from Windows' registry 		c:\oracle\network\admin

Custom URL

For a more sophisticated configuration, you can specify the full JDBC URL manually ( see Data Sources and URLs).

Sample URL (Oracle Cloud):
jdbc:oracle:thin:@(description= (retry_count=20)(retry_delay=3)(address=(protocol=tcps)(port=1522)(host=adb.us-ashburn-1.oraclecloud.com))(connect_data=(service_name=xxxxxxxxxxxxxxxxx_high.adb.oraclecloud.com))(security=(ssl_server_cert_dn="CN=adwc.uscom-east-1.oraclecloud.com, OU=Oracle BMCS US, O=Oracle Corporation, L=Redwood City, ST=California, C=US")))

Authentication

Database
Parameter Description Example
User name Database user name SYS
Password Database user password
Role Role for connection.
Roles SYSDBA and SYSOPER are needed for some administrative operations 		Normal
Save password Saves the user/password information in the local DBeaver configuration SID

OS authentication

The Oracle driver gets user information from the current OS user.
You do not need to explicitly specify any credentials.

Oracle Wallet

A more secure way to connect is to use the Oracle Wallet. Wallet is a directory with security keys and some other optional connection information. Wallets are usually distributed as ZIP archives. You need to extract the ZIP archive to a folder on a disk and specify this folder in the Wallet location field.

Wallet may contain information about a database user. This, however, is optional. You will sometimes need to specify the user too.

Wallet may also contain a TNS configuration. If it does, you can use the TNS connection configuration easily by setting the TNS path to the same value as the Wallet location.

Parameter Description Example
User name, Password, Role See Database authentication
Wallet location Oracle wallet directory C:\oracle\network\wallet\example
Wallet password Optional. Some wallets are password-protected

Kerberos

Kerberos is the most complicated authentication in Oracle.

Parameter Description Example
Username Database user name c##testuser
Kerberos user Kerberos / Active directory user name testuser@THE-REALM
Realm Kerberos realm THE-REALM
KDC server KDC server address krb5.your-domain.com
Password Kerberos user password

Oracle Cloud connections

DBeaver supports Oracle Cloud Autonomous databases connectivity.
There are two ways to authenticate:

Plain URL connection
  • To use a plain URL connection you must enable the Access control list for the Oracle autonomous database.
  • Then add your IP address to the IP list.

  • Use the Custom connection configuration (URL). You can copy the URL from the Oracle Cloud database page (link "DB Connection").

Oracle Wallet connection

It is the default authentication type for the Oracle Cloud.
.

  • Download Wallet from the Oracle Cloud website
  • Expand the wallet archive to a folder
  • Set TNS configuration type
  • Set the TNS path to the wallet location directory
  • Choose the proper Network Alias from the drop-down menu
  • Set Authentication to the Oracle Wallet
  • Set the database username and password (you can get them from the Oracle Cloud database information page)
  • Set the Wallet location to the wallet location directory
