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/AnaplanODBCDriverforUnix.deb 

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

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

Licensing the Driver

Run the following commands to license the driver. To activate a trial, omit the <key> input.

cd /opt/cdata/cdata-odbc-driver-for-anaplan/bin/
sudo ./install-license.sh <key>

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.

Connecting to Anaplan

To authenticate to Anaplan, you can use Basic, Certificate, or OAuth authentication.

Basic

Set the following connection properties to connect to Anaplan using Basic authentication:

• AuthScheme: Set this to Basic.
• User: Your Anaplan username.
• Password: The password for your Anaplan account.
• Region: The region where your account data is hosted.

Note: If your workspace uses single sign-on (SSO), you must be assigned as an Exception User to use Basic authentication.

Certificate

Set the following connection properties to connect to Anaplan using Certificate authentication:

• AuthScheme: Set this to Certificate.
• Certificate: The absolute path to the certificate file or the certificate content in PEM format encoded in Base64, depending on the value of CertificateType.
• CertificateType: The type of Certificate.
• CertificatePassword: The password for the certificate, if the certificate is password-protected.
• PrivateKey: The absolute path to the private key file or the private key content in PEM format encoded in Base64, depending on the value of PrivateKeyType.
• PrivateKeyType: The type of PrivateKey.
• PrivateKeyPassword: The password for the private key, if the private key is encrypted.
• Region: The region where your account data is hosted.

The certificate must be a CA-issued X.509 certificate that has been registered with your Anaplan tenant administrator.

OAuth

Desktop Applications

You must create a custom OAuth application. See Creating a Custom OAuth App for information about creating custom applications.

Get and Refresh the OAuth Access Token

After setting the following, you are ready to connect:

• InitiateOAuth: GETANDREFRESH. You can use InitiateOAuth to avoid repeating the OAuth exchange and manually setting the OAuthAccessToken.
• OAuthClientId: The client Id assigned when you registered your application.
• OAuthClientSecret: The client secret assigned when you registered your application.
• CallbackURL: The redirect URI defined when you registered your application.
• Region: The region where your account data is hosted. Defaults to US1.

When you connect, the driver opens Anaplan's OAuth endpoint in your default browser. Log in and grant permissions to the application. The driver then completes the OAuth process:

1. The driver obtains an access token from Anaplan and uses it to request data.
2. The OAuth values are saved in the location specified in OAuthSettingsLocation. These values persist across connections.

The driver refreshes the access token automatically when it expires.

Headless Machines

To configure the driver to use OAuth with a user account on a headless machine, you need to authenticate on another device that has an internet browser.

1. Choose one of two options:
   • Option 1: Obtain the OAuthVerifier value as described in "Obtain and Exchange a Verifier Code" below.
   • Option 2: Install the driver on a machine with an internet browser and transfer the OAuth authentication values after you authenticate through the usual browser-based flow, as described in "Transfer OAuth Settings" below.
2. Then configure the driver to automatically refresh the access token on the headless machine.

Option 1: Obtain and Exchange a Verifier Code

To obtain a verifier code, you must authenticate at the OAuth authorization URL.

Follow the steps below to authenticate from the machine with an internet browser and obtain the OAuthVerifier connection property.

1. Choose one of these options:
   • If you are using the Embedded OAuth Application, call the GetOAuthAuthorizationUrl stored procedure. Open the URL returned by the stored procedure in a browser.
   • If you are using a custom OAuth application, set the following properties:
     • InitiateOAuth: Set to OFF.
     • OAuthClientId: Set to the client Id assigned when you registered your application.
     • OAuthClientSecret: Set to the client secret assigned when you registered your application.
     Then call the GetOAuthAuthorizationUrl stored procedure with the appropriate CallbackURL. Open the URL returned by the stored procedure in a browser.
2. Log in and grant permissions to the driver. You are then redirected to the redirect URI. There will be a parameter called code appended to the redirect URI. Note the value of this parameter. Later you will set this in the OAuthVerifier connection property.

Next, you need to exchange the OAuth verifier code for OAuth refresh and access tokens.

On the headless machine, set the following connection properties to obtain the OAuth authentication values:

• InitiateOAuth: REFRESH
• OAuthVerifier: The noted verifier code (the value of the code parameter in the redirect URI).
• OAuthClientId: The client Id in your custom OAuth application settings.
• OAuthClientSecret: The client secret in the custom OAuth application settings.
• OAuthSettingsLocation: Set this to persist the encrypted OAuth authentication values to the specified location.

Test the connection to generate the OAuth settings file, then re-set the following properties to connect:

• InitiateOAuth: REFRESH
• OAuthClientId: The client Id assigned when you registered your application.
• OAuthClientSecret: The client secret assigned when you registered your application.
• OAuthSettingsLocation: The location containing the encrypted OAuth authentication values. Make sure this location gives read and write permissions to the driver to enable the automatic refreshing of the access token.

Option 2: Transfer OAuth Settings

Prior to connecting on a headless machine, you need to install and create a connection with the driver on a device that supports an internet browser. Set the connection properties as described in "Desktop Applications" above.

After completing the instructions in "Desktop Applications", the resulting authentication values are encrypted and written to the location specified by OAuthSettingsLocation. The default filename is OAuthSettings.txt.

Test the connection to generate the OAuth settings file, then copy the OAuth settings file to your headless machine.

On the headless machine, set the following connection properties to connect to data:

• InitiateOAuth: REFRESH
• OAuthClientId: The client Id assigned when you registered your application.
• OAuthClientSecret: The client secret assigned when you registered your application.
• OAuthSettingsLocation: The location of the OAuth settings file you copied from the machine with the browser. Make sure this location gives read and write permissions to the driver to enable the automatic refreshing of the access token.

Refreshing OAuth Values

The driver can refresh the temporary OAuth access tokens obtained during the browser-based OAuth authentication exchange. By default, the driver saves the encrypted tokens in the odbc.ini file corresponding to the DSN. Access to this odbc.ini file can be restricted in the case of System DSNs.

To enable the automatic token exchange, you can give the driver write access to the system odbc.ini. Or, you can set the OAuthSettingsLocation connection property to an alternate file path, to which the driver would have read and write access.

    OAuthSettingsLocation=/tmp/oauthsettings.txt
    

Installing Dependencies for OAuth Authentication

The OAuth authentication standard requires the authenticating user to interact with Anaplan, using a web-browser. If the first OAuth interaction is to be done on the same machine the driver is installed on, for example, a desktop application, the driver needs access to the xdg-open program, which opens the default browser.

To satisfy this dependency, install the corresponding package with your package manager:

Debian/Ubuntu Package	RHEL/Fedora Package	File
xdg-utils	xdg-utils	xdg-open

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/cdata-odbc-driver-for-anaplan/lib/cdata.odbc.anaplan.ini':

[Driver]
AnsiCodePage = 932
