macOS DSN Configuration
This section shows how to set up ODBC connectivity and configure DSNs on macOS.
Minimum macOS Version
The CData ODBC Driver for IBM Cloud Object Storage driver requires macOS Sierra (10.12) or above.
Licensing the Driver
In a terminal, run the following commands to license the driver. To activate a trial, omit the <key> input.
cd "/Applications/CData ODBC Driver for IBM Cloud Object Storage/bin" sudo ./install-license <key>
You'll be prompted for a name and password. These refer to your name and your machine's password.
Connecting through a Driver Manager
On macOS, the CData ODBC Driver for IBM Cloud Object Storage is preconfigured for use with the iODBC driver manager, as are many other products like Filemaker Pro, Microsoft Excel, and Tableau. You can find the latest version of iODBC on the iODBC site.
The driver installation registers the driver with iODBC and creates a system DSN, which you can use in any tools or applications that support ODBC connectivity.
The driver manager loads the driver and passes function calls from the application to the driver. The driver must be registered with the driver manager and DSNs are defined in the driver manager's configuration files.
To configure a DSN, you can use the iODBC Administrator 64-bit, the GUI installed with iODBC. Note that the ODBC Manager must match the bitness of the ODBC driver. The most recent version of the CData ODBC Driver for IBM Cloud Object Storage is 64-bit only. Alternatively, you can edit the iODBC configuration files.
You can configure User or System DSNs. User data sources are restricted to a user account. System data sources can be accessed by all users.
Configuring a DSN with the iODBC Administrator
You can create user DSNs by opening the iODBC Administrator 64-bit from Launchpad.
To modify the system DSN installed by the driver or create a system DSN, open the iODBC Administrator 64-bit with elevated permissions. To do so, enter the following command into a terminal:
sudo /Applications/iODBC/iODBC\ Administrator64.app/Contents/MacOS/iODBC\ Administrator64After opening the iODBC Administrator 64-bit, you will see the CData IBMCloudObjectStor~ Source listed under the System tab. Select the DSN and click the Configure button to set connection properties as name-value pairs.
To create your own DSN, instead click Add on the User or System tab and then select the CData ODBC Driver for IBM Cloud Object Storage option.
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:
- Log in to your IBM Cloud account.
- 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:
To connect with IBM Cloud Object Storage, you will need an ApiKey. You can obtain this as follows:
- Log in to your IBM Cloud account.
- Navigate to the Platform API Keys page.
- On the middle-right corner click Create an IBM Cloud API Key to create a new API Key.
- 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.
Configuring a DSN in the iODBC INI Files
Configure DSNs in odbc.ini. Register ODBC drivers in odbcinst.ini.
Define ODBC data sources in sections in the odbc.ini file. User data sources can only be accessed by the user account whose home folder the odbc.ini is located in. System data sources can be accessed by all users.
Modifying iODBC's system-wide settings requires elevated permissions; to do so, you can use the sudo command to open a text editor from the terminal. For example:
sudo nano /Library/ODBC/odbc.ini
In addition to the connection properties required to connect to your data source, the Driver property specifies either a driver definition in the odbcinst.ini file or the path to the driver library.
[CData IBMCloudObjectStor~ Source] Driver = CData ODBC Driver for IBM Cloud Object Storage ApiKey=myApiKey CloudObjectStorageCRN=MyInstanceCRN Region=myRegion OAuthClientId=MyOAuthClientId OAuthClientSecret=myOAuthClientSecret
Additionally, in the ODBC Data Sources section, the DSN must be set to a driver defined in the odbcinst.ini file. For example, below is the entry for the DSN created during the driver install:
[ODBC Data Sources] CData IBMCloudObjectStor~ Source = CData ODBC Driver for IBM Cloud Object Storage
You may need to modify the installed driver definition if you change the path to the driver library.
To register an ODBC driver, modify the odbcinst.ini file. With iODBC, drivers can be available to only one user account or drivers can be available system wide.
Drivers are defined in sections in the odbcinst.ini file. The section name specifies the name of the driver. In this section, the Driver property specifies the path to the driver library. The driver library is the .dylib file located in the lib subfolder of the installation directory, by default in /Applications/CData ODBC Driver for IBM Cloud Object Storage.
[CData ODBC Driver for IBM Cloud Object Storage] Driver = /Applications/CData ODBC Driver for IBM Cloud Object Storage/lib/libibmcloudobjectstorageodbc.dylib
The ODBC Drivers section must also contain a property with the driver name, set to "Installed". For example:
[ODBC Drivers] CData ODBC Driver for IBM Cloud Object Storage = Installed
Testing the Connection
You can use the iODBC Demo, available in most iODBC installations, to connect to IBM Cloud Object Storage and execute SQL queries.
Complete the following steps to connect from the iODBC Demo:
- Open Launchpad and search for "iODBC".
- If you need to connect to IBM Cloud Object Storage from an application that can use only the ANSI ODBC API, click iODBC Demo Ansi. Otherwise, click iODBC Demo Unicode.
- In the Environment menu, click Open Connection.
- Select the DSN on the corresponding tab and test the connection.
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 Mac are configured to use UTF-32 which is compatible with iODBC, 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 '/Applications/CData ODBC Driver for IBM Cloud Object Storage/lib/cdata.odbc.ibmcloudobjectstorage.ini':
[Driver] AnsiCodePage = 932
Uninstalling the Driver
The easiest way to uninstall the driver is to open a terminal and run the included uninstall.sh script, located in the installation directory. For example:
cd "/Applications/CData ODBC Driver for IBM Cloud Object Storage" sudo ./uninstall.sh
Note: The script needs to be run from the installation directory.
