Access Adobe Target Data as a Remote Oracle Database

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 Adobe Target to create a database link from Adobe Target to Oracle and to query Adobe Target data through the SQL*Plus tool. You can also create the database link and execute queries from SQL Developer.

Connect to Adobe Target as an ODBC Data Source

Information for connecting to Adobe Target follows, along with different instructions for configuring a DSN in Windows and Linux environments.

To connect to Adobe Target, you must provide the Tenant property along with OAuth connection properties mentioned below. Note that while other connection properties can influence processing behavior, they do not affect the ability to connect.

To determine your Tenant name:

1. Log in to Adobe Experience. The URL will look similar to: "https://experience.adobe.com/#/@mycompanyname/preferences/general-section".
2. Extract the value after the "/#/@". In this example, it is "mycompanyname".
3. Set the Tenant connection property to that value.

User Accounts (OAuth)

You must set AuthScheme to OAuthClient for all user account flows.

Note: Adobe authentication via OAuth requires updating your token every two weeks.

All Applications

Obtaining the OAuth Access Token

Set the following properties to connect:

• InitiateOAuth: Set to GETANDREFRESH to automatically perform the OAuth exchange and refresh the OAuthAccessToken as needed.
• OAuthClientId : Set to the client Id assigned when you registered your app.
• OAuthClientSecret : Set to the client secret assigned when you registered your app.
• CallbackURL : Set to the redirect URI defined when you registered your app. For example: https://localhost:3333

With these settings, the provider obtains an access token from Adobe Target, which it uses to request data. The OAuth values are stored in the location specified by OAuthSettingsLocation, ensuring they persist across connections.

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 Adobe Target 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 Adobe Target 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 AdobeTarget Source]
Driver = CData ODBC Driver for Adobe Target
Description = My Description
Tenant = mycompanyname

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 Adobe Target data just as you would an Oracle database. Set the following properties when working with Adobe Target 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-adobetarget/lib/cdata.odbc.adobetarget.ini in a text editor and set the encoding.

cdata.odbc.adobetarget.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 Adobe Target data that enables you to query live Adobe Target data as an Oracle database.

1. Create the file initmyadobetargetdb.ora in the folder oracle-home-directory/hs/admin and add the following setting:

   initmyadobetargetdb.ora

   HS_FDS_CONNECT_INFO = "CData AdobeTarget Sys"

2. 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 = myadobetargetdb)
         (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 = myadobetargetdb)
         (ORACLE_HOME = your-oracle-home)
         (PROGRAM = hsodbc)
       )
     )
   

3. Add the connect descriptor below in tnsnames.ora, located in oracle-home-directory/NETWORK/admin:

   tnsnames.ora

   myadobetargetdb  =
     (DESCRIPTION=
       (ADDRESS=(PROTOCOL=tcp)(HOST=localhost)(PORT=1521))
       (CONNECT_DATA=(SID=myadobetargetdb))
       (HS=OK)
     ) 
   

4. Restart the listener.

5. Test the configuration with the following command:

   tnsping myadobetargetdb

6. Open SQL*Plus and create the database link with the command below:

   CREATE DATABASE LINK myadobetargetdb CONNECT TO "user" IDENTIFIED BY "password" USING 'myadobetargetdb';

You can now execute queries in SQL*Plus like the one below (note the double quotation marks around the table name):

SELECT * from "Activities"@myadobetargetdb WHERE Type = 'AB';
