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), CentOS, and Fedora.
Minimum Linux Versions
Here are the minimum supported versions for Red Hat-based and Debian-based systems:
| OS | Min. Version |
| Ubuntu | 11.04 |
| Debian | 7 |
| RHEL | 6.9 |
| CentOS | 6.9 |
| Fedora | 13 |
| SUSE | 12.1 |
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/CentOS/Fedora:
yum install glibc libstdc++ zlib libgcc
Here are the corresponding libraries required by the driver:
| Debian/Ubuntu Package | RHEL/CentOS/Fedora Package | File |
| libc6 | glibc | linux-vdso.1 |
| libc6 | glibc | libm.so.6 |
| libc6 | glibc | librt.so.1 |
| libc6 | glibc | libdl.so.2 |
| libc6 | glibc | libpthread.so.0 |
| libc6 | glibc | libc.so.6 |
| libc6 | glibc | ld-linux-x86-64.so.2 |
| libstdc++6 | libstdc++ | libstdc++.so.6 |
| zlib1g | zlib | libz.so.1 |
| libgcc1 | libgcc | libgcc_s.so.1 |
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/TeradataODBCDriverforUnix.deb
On systems that support the RPM package format, run the following command with root or sudo:
rpm -ivh /path/to/driver/TeradataODBCDriverforUnix.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-teradata/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.
Deploying the Driver
Begin by downloading the official Teradata JDBC driver.
There are two options available for including the required dependencies. Select one of the following.
- Place the driver jar into the installation/lib directory. Ex: /opt/cdata/cdata-odbc-driver-for-teradata/lib
- Place the driver jar into the same folder as the ODBC jar file. Additionally, set: ClassPath=terajdbc4.jar.
The driver wraps the official Teradata Database driver; you can connect to the CData ODBC Driver for Teradata using the same connection properties and access the same functionality as the underlying Teradata driver. You also need to install the official driver alongside the CData ODBC Driver for Teradata.
Connecting to Teradata
Required Properties
To connect to Teradata, provide the following authentication information and specify the database server name.
- AuthScheme: Set this to either TD2 (default) or LDAP depending on the required authentication mechanism of your Teradata server.
- User: Set this to the user name of a Teradata user.
- Password: Set this to the password of the Teradata user.
- DataSource: Specify the Teradata server name, DBC Name, or TDPID.
- Port: Specify the port the server is running on.
- Database: Specify the database name. If not specified, the driver connects to the default database.
TLS/SSL Configuration
Enable DataEncryption to encrypt connections with TLS/SSL.
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-teradata/lib/cdata.odbc.teradata.ini':
[Driver]
AnsiCodePage = 932
