Configure Driver and Data Sources
Do the following to configure the driver and the data sources:
- Open the ODBC Data Source Administrator tool.
- Click Add in the User DSN or System DSN tabs.
- Select EXASolution Driver in the Create New Data Source dialog and click Finish.
- Select Connection tab in the EXASolution ODBC configuration dialog.
- Enter the following details:
- Datasource name: Name of the new ODBC data source
- Connection string: List of host names or IP addresses and the port of the Exasol cluster (for example,
192.168.6.11..14:8563).The system must be capable of resolving the host names. If it is not possible, contact your network administrator.
- Encryption: Enables or disables the automatic encryption.
- Username: Name of the default user for this connection.
- Password: Password of the default user.
- Default schema: The name of the schema that is automatically opened when the connection is established. If this schema is not available during the attempt at establishing the connection, an error message is displayed and the connection with Exasol fails.
- Test connection: You can use this to test whether the connection data has been entered correctly. This initiates a connection with Exasol.
- (Optional) Click Advanced tab and define the following options and click OK:
- SQL Prepare always successful
- Log file
- Log mode
- Character locale (LC_CTYPE)

The new connection appears in the list of Windows data sources.
The Connection Pooling of the driver manager is deactivated by default, you can activate it in the configuration tool "ODBC Data Source Administrator". In that case reused connections keep their session settings which were set through SQL commands (for more information, see ALTER SESSION).
