ODBC Driver for IBM Cloud Object Storage

Build 20.0.7654

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:

OSMin. Version
Ubuntu11.04
Debian7
RHEL6.9
CentOS6.9
Fedora13
SUSE12.1

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 PackageRHEL/CentOS/Fedora PackageFile
libc6glibclinux-vdso.1
libc6glibclibm.so.6
libc6glibclibrt.so.1
libc6glibclibdl.so.2
libc6glibclibpthread.so.0
libc6glibclibc.so.6
libc6glibcld-linux-x86-64.so.2
libstdc++6libstdc++libstdc++.so.6
zlib1gzliblibz.so.1
libgcc1libgcclibgcc_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/IBMCloudObjectStorageODBCDriverforUnix.deb 

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

rpm -ivh /path/to/driver/IBMCloudObjectStorageODBCDriverforUnix.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-ibmcloudobjectstorage/bin/
sudo ./install-license.x64 <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.

Register a New Instance of Cloud Object Storage

If you do not already have Cloud Object Storage in your IBM Cloud account, you can follow the procedure below to install an instance of SQL Query in your account:

  1. Log in to your IBM Cloud account.
  2. Navigate to the Cloud Object Storage page, choose a name for your instance and click Create. You will be redirected to the instance of Cloud Object Storage you just created.

Connecting using OAuth Authentication

There are certain connection properties you will need to set before you can connect. You can obtain these as follows:

API Key

To connect with IBM Cloud Object Storage, you will need an ApiKey. You can obtain this as follows:

  1. Log in to your IBM Cloud account.
  2. Navigate to the Platform API Keys page.
  3. On the middle-right corner click Create an IBM Cloud API Key to create a new API Key.
  4. In the pop-up window, specify the API Key name and click Create. Note the ApiKey as you can never access it again from the dashboard.

Cloud Object Storage CRN

By default, the driver will attempt to automatically determine a Cloud Object Storage CRN. However, if you have multiple accounts, you will need to specify the CloudObjectStorageCRN explicitly. To find the appropriate value, you can:

  • Query the Services view. This will list your IBM Cloud Object Storage instances along with the CRN for each.
  • Locate the CRN directly in IBM Cloud. To do so, navigate to your IBM Cloud Dashboard. In the Resource List, Under Storage, select your Cloud Object Storage resource to get its CRN.

Connecting to Data

You can now set the following to connect to data:

  • ApiKey: Set this to your API key which was noted during setup.
  • CloudObjectStorageCRN (Optional): Set this to the cloud object storage CRN you want to work with. While the driver attempts to retrieve this automatically, specifying this explicitly is recommended if you have more than one Cloud Object Storage account.

When you connect, the driver completes the OAuth process.

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