Linux DSN Configuration

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/SAPHANAODBCDriverforUnix.deb

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

rpm -ivh /path/to/driver/SAPHANAODBCDriverforUnix.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-saphana/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 SAP HANA Cloud

Set the following to connect to data:

Server: Set this property to the name or network address of the SAP HANA database instance.
Port: Set this to 443.
UseSSL: Set this to True.

Connecting to SAP HANA On-Prem

Set the following to connect to data:

Server: Set this property to the name or network address of the SAP HANA database instance.
Port: The port of the server hosting the SAP HANA database.

Authenticating to SAP HANA

Once you have provided the connection details, set the following database credentials to authenticate to SAP HANA:

User: The username provided for authentication with the SAP HANA database.
Password: The password provided for authentication with the SAP HANA database.

Okta

Set the AuthScheme to Okta. The following connection properties are used to connect to Okta:

User: Set this to the Okta user.
Password: Set this to Okta password for the user.
SSOProperties (optional): Set this to the OTP code that was sent to your device. This property should be used only when MFA is required for OKTA sign on.

The following SSOProperties are needed to authenticate to Okta:

SSOLoginUrl: Set this to the OKTA's login URL.
MFAType (optional): Set this to the multi-factor type. This property should be used only when MFA is required for OKTA sign on. This property accepts one of the following values:
- OKTAVerify
- Email
- SMS
APIToken (optional): Set this to the API Token that the customer created from the Okta org. It should be used when authenticating a user via a trusted application or proxy that overrides OKTA client request context.

The following is an example connection string:

AuthScheme=OKTA;User=username;Password=password;Server=myserver;SSO Properties='SSOLoginUrl=https://cdata-okta.okta.com';

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-saphana/lib/cdata.odbc.saphana.ini':

[Driver]
AnsiCodePage = 932
