Oracle Connector

This node creates a connection to an Oracle server via an Oracle JDBC driver. Due to license restrictions the Oracle JDBC driver is not part of the KNIME Analytics Platform and needs to be downloaded and registered separately. For more details on where to download and how to register the Oracle driver see the database documentation.
You need to provide the server's hostname (or IP address), the port, and a database name. Login credentials can either be provided directly in the configuration or via credential variables.

This node uses the selected driver's JDBC URL template to create the concrete database URL. Field validation in the dialog depends on whether the (included) tokens referencing them are mandatory or optional in the template.

Options

Connection settings

Database Dialect
Choose the registered database dialect here.
Database Driver

Choose the JDBC driver to connect to the database here. If you select "Use latest driver version available" upon execution the node will automatically use the driver with the latest (highest) driver version that is available for the current database type. This has the advantage that you do not need to touch the workflow after a driver update. However, the workflow might break in the rare case that the behavior of the driver e.g. type mapping changes with the newer version.

If this option is not enabled, you can select a specific version of the registered drivers via the drop-down list. Additional drivers can be registered via KNIME's preference page "KNIME -> Databases". For more details on how to register a new driver see the database documentation.

Hostname
The hostname (or IP address) of a Oracle server. The corresponding driver URL template variable is host.
Port
The port on which the Oracle server is listening. The default port is 1,521. The corresponding driver URL template variable is port.
Database name
The name of the database you want to connect to. The corresponding driver URL template variable is database.
None
Sending no credentials is required for some Oracle specific logins such as Oracle Wallet. Please refer to the Oracle documentation for any further setup steps that might be required.
Credentials
If checked, the credentials (user and password) are used as defined on the workflow. The credential name links to the specified user and password.
Username & password
Your log-in user name and password for the database. Note that the password is encrypted before storage and decrypted afterwards for being used internally.
Kerberos
Uses an existing Kerberos ticket for authentication.
For more details on how to configure and use Kerberos in KNIME Analytics Platform see the Kerberos User Guide.

JDBC Parameters

This tab allows you to define JDBC driver connection parameter. The value of a parameter can be a constant, variable, credential user, credential password or KNIME URL. For more information about the supported driver properties see the Oracle documentation.

Advanced

This tab allows you to define KNIME framework properties such as connection handling, advanced SQL dialect settings or logging options.

Input Type Mapping

This tab allows you to define rules to map from database types to KNIME types.

Mapping by Name
Columns that match the given name (or regular expression) and database type will be mapped to the specified KNIME type.
Mapping by Type
Columns that match the given database type will be mapped to the specified KNIME type.

Output Type Mapping

This tab allows you to define rules to map from KNIME types to database types.

Mapping by Name
Columns that match the given name (or regular expression) and KNIME type will be mapped to the specified database type.
Mapping by Type
Columns that match the given KNIME type will be mapped to the specified database type.
