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/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.
Connecting to CData Connect Cloud
Follow these steps to connect to CData Connect Cloud:
- AuthScheme: Select OAuth.
- Click Test Connection or Sign In to open the OAuth sign in page.
- Enter your CData Connect Cloud credentials and sign in.
Connecting to CData Connect Server
Enter following connection properties to connect to CData Connect Server:
- AuthScheme: Select 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':
