Get the Report →Access Unbounce Data as a Remote Oracle Database
Use the Oracle ODBC Gateway and Heterogeneous Services technology to access Unbounce data from your Oracle system.
The Oracle Database Gateway for ODBC and Heterogeneous Services technology enable you to connect to ODBC data sources as remote Oracle databases. This article shows how to use the CData ODBC Driver for Unbounce to create a database link from Unbounce to Oracle and to query Unbounce data through the SQL*Plus tool. You can also create the database link and execute queries from SQL Developer.
Connect to Unbounce as an ODBC Data Source
Information for connecting to Unbounce follows, along with different instructions for configuring a DSN in Windows and Linux environments.
Start by setting the Profile connection property to the location of the Unbounce Profile on disk (e.g. C:\profiles\Unbounce.apip). Next, set the ProfileSettings connection property to the connection string for Unbounce (see below).
Unbounce API Profile Settings
Unbounce uses OAuth to authenticate to your data.
In order to authenticate to Unbounce, you will first need to register an OAuth application. To do so, go to https://developer.unbounce.com/getting_started/ and complete the Register OAuth Application form.
After setting the following connection properties, you are ready to connect:
- AuthScheme: Set this to OAuth.
- InitiateOAuth: Set this to GETANDREFRESH. You can use InitiateOAuth to manage the process to obtain the OAuthAccessToken.
- OAuthClientId: Set this to the Client Id that is specified in your app settings.
- OAuthClientSecret: Set this to Client Secret that is specified in your app settings.
- CallbackURL: Set this to the Redirect URI you specified in your app settings.
Windows
If you have not already, first specify connection properties in an ODBC DSN (data source name). This is the last step of the driver installation. You can use the Microsoft ODBC Data Source Administrator to create and configure ODBC DSNs.
Note: If you need to modify the DSN or create other Unbounce DSNs, you must use a system DSN and the bitness of the DSN must match your Oracle system. You can access and create 32-bit DSNs on a 64-bit system by opening the 32-bit ODBC Data Source Administrator from C:\Windows\SysWOW64\odbcad32.exe.
Linux
If you are installing the CData ODBC Driver for Unbounce in a Linux environment, the driver installation predefines a system DSN. You can modify the DSN by editing the system data sources file (/etc/odbc.ini) and defining the required connection properties.
/etc/odbc.ini
[CData API Source]
Driver = CData ODBC Driver for Unbounce
Description = My Description
Profile = C:\profiles\Unbounce.apip
Authscheme = OAuth
OAuthClientId = your_client_id
OAuthClientSecret = your_client_secret
CallbackUrl = your_callback_url
For specific information on using these configuration files, please refer to the help documentation (installed and found online).
Set Connection Properties for Compatibility with Oracle
The driver provides several connection properties that streamline accessing Unbounce data just as you would an Oracle database. Set the following properties when working with Unbounce data in SQL*Plus and SQL Developer. For compatibility with Oracle, you will need to set the following connection properties, in addition to authentication and other required connection properties.
MapToWVarchar=False
Set this property to map string data types to SQL_VARCHAR instead of SQL_WVARCHAR. By default, the driver uses SQL_WVARCHAR to accommodate various international character sets. You can use this property to avoid the ORA-28528 Heterogeneous Services data type conversion error when the Unicode type is returned.
MaximumColumnSize=4000
Set this property to restrict the maximum column size to 4000 characters.
IncludeDualTable=True
Set this property to mock the Oracle DUAL table. SQL Developer uses this table to test the connection.
Linux Configuration
In Linux environments, Oracle uses UTF-8 to communicate with the unixODBC Driver manager, whereas the default driver encoding is UTF-16. To resolve this, open the file /opt/cdata/cdata-driver-for-api/lib/cdata.odbc.api.ini in a text editor and set the encoding.
cdata.odbc.api.ini
[Driver]
DriverManagerEncoding = UTF-8
Configure the ODBC Gateway, Oracle Net, and Oracle Database
Follow the procedure below to set up an ODBC gateway to Unbounce data that enables you to query live Unbounce data as an Oracle database.
-
Create the file initmyunbouncedb.ora in the folder oracle-home-directory/hs/admin and add the following setting:
initmyunbouncedb.ora
HS_FDS_CONNECT_INFO = "CData API Sys"
-
Add an entry to the listener.ora file. This file is located in oracle-home-directory/NETWORK/admin.
If you are using the Database Gateway for ODBC, your listener.ora needs to have a SID_LIST_LISTENER entry that resembles the following:
listener.ora
SID_LIST_LISTENER = (SID_LIST = (SID_DESC = (SID_NAME = myunbouncedb) (ORACLE_HOME = your-oracle-home) (PROGRAM = dg4odbc) ) )
If you are using Heterogeneous Services, your listener.ora needs to have a SID_LIST_LISTENER entry that resembles the following:
listener.ora
SID_LIST_LISTENER = (SID_LIST = (SID_DESC = (SID_NAME = myunbouncedb) (ORACLE_HOME = your-oracle-home) (PROGRAM = hsodbc) ) )
-
Add the connect descriptor below in tnsnames.ora, located in oracle-home-directory/NETWORK/admin:
tnsnames.ora
myunbouncedb = (DESCRIPTION= (ADDRESS=(PROTOCOL=tcp)(HOST=localhost)(PORT=1521)) (CONNECT_DATA=(SID=myunbouncedb)) (HS=OK) )
- Restart the listener.
Test the configuration with the following command:
tnsping myunbouncedb
-
Open SQL*Plus and create the database link with the command below:
CREATE DATABASE LINK myunbouncedb CONNECT TO "user" IDENTIFIED BY "password" USING 'myunbouncedb';
You can now execute queries in SQL*Plus like the one below (note the double quotation marks around the table name):
SELECT * from "Tags"@myunbouncedb WHERE State = 'active';
