This section describes how to set up ODBC connectivity and configure DSNs on several Linux distributions: Debian-based systems, like Ubuntu, and Red Hat Linux platforms, like Red Hat Enterprise Linux (RHEL) and Fedora.

Minimum Linux Versions

Here are the minimum supported versions for Red Hat-based and Debian-based systems:

OS	Min. Version
Ubuntu	18.04
Debian	10
RHEL	8
Fedora	28
SUSE	15

Installing the Driver Dependencies

Run the following commands as root or with sudo to install the necessary dependencies:

• Debian/Ubuntu:
  

  apt-get install libc6 libstdc++6 zlib1g libgcc1

• RHEL/Fedora:
  

  yum install glibc libstdc++ zlib libgcc

Installing the Driver

You can use standard package management systems to install the driver.

On Debian-based systems, like Ubuntu, run the following command with root or sudo:

dpkg -i /path/to/driver/setup/ConnectODBCDriverforUnix.deb 

On systems that support the RPM package format, run the following command with root or sudo:

rpm -ivh /path/to/driver/ConnectODBCDriverforUnix.rpm 

Connecting through the Driver Manager

The driver manager loads the driver and passes function calls from the application to the driver. You need to register the driver with the driver manager and you define DSNs in the driver manager's configuration files.

The driver installation registers the driver with the unixODBC driver manager and creates a system DSN. The unixODBC driver manager can be used from Python and from many other applications. Your application may embed another driver manager.

Creating the DSN

See Using unixODBC to install unixODBC and configure DSNs. See Using the DataDirect Driver Manager to create a DSN to connect to OBIEE, Informatica, and SAS.

Establishing a Connection

Connecting to CData Connect Cloud

CData Connect Cloud supports two ways to authenticate: OAuth and ClientJWT.

OAuth Authentication

Use OAuth authentication when you want users to authenticate interactively via their CData Connect Cloud credentials. To configure OAuth authentication, set the following in the Admin Console:

• AuthScheme: OAuth.
• Click Test Connection or Sign In to open the OAuth sign-in page.
• Enter your CData Connect Cloud credentials and sign-in.

ClientJWT Authentication

Use ClientJWT authentication when your application needs to connect using a pre-signed JWT token. This method is commonly used in OEM deployments or automated workflows. To configure ClientJWT authentication, set the following connection properties in the Admin Console:

• AuthScheme: ClientJWT.
• ClientJWTCert: Path to the certificate file used to sign the JWT.
• ClientJWTCertType: Format of the certificate file (PEM or PFX).
• ClientJWTCertPassword: Password for the certificate file (if applicable).
• ClientJWTIssuer: The OEM's account ID.
• ClientJWTSubject: The customer's account ID.
• ClientJWTValidityTime (optional): Expiry duration of the JWT in seconds. Default is 3600.

Connecting to CData Connect Server

To connect to CData Connect Server, set the following connection properties in the Admin Console:

• AuthScheme: Basic.
• URL: The REST URL found on the Endpoints page of the Admin Console.
• User: A user that you configured in the Connect Server dashboard.
• Password: The AuthToken for the chosen user.

Set the Driver Encoding

The ODBC drivers need to specify which encoding to use with the ODBC Driver Manager. By default, the CData ODBC Drivers for Unix are configured to use UTF-16 which is compatible with unixODBC, but other Driver Managers may require alternative encoding.

Alternatively, if you are using the ODBC driver from an application that uses the ANSI ODBC API it may be necessary to set the ANSI code page. For example, to import Japanese characters in an ANSI application, you can specify the code page in the config file '/opt/cdata/odbc-driver-for-connect/lib/cdata.odbc.connect.ini':

[Driver]
AnsiCodePage = 932
