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

Connect to Anaplan as an ODBC Data Source

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

Authenticating to Anaplan

The driver supports authenticating with Basic, Certificate, or OAuth. In every case, set Region to the region where your Anaplan account data is hosted (e.g., , which is the default).

Using Basic Authentication

Set AuthScheme to , then supply your Anaplan User and Password. If your workspace uses single sign-on (SSO), you must be assigned as an Exception User to use Basic authentication.

Using Certificate Authentication

Set AuthScheme to , then supply the Certificate, CertificateType, and PrivateKey properties (and the matching CertificatePassword / PrivateKeyPassword if either is encrypted). The certificate must be a CA-issued X.509 certificate registered with your Anaplan tenant administrator.

Using OAuth Authentication

Register a custom OAuth application in Anaplan, then set the following properties:

• OAuthClientId: The client Id assigned when you registered your custom OAuth application.
• OAuthClientSecret: The client secret assigned when you registered your custom OAuth application.
• CallbackURL: The redirect URI defined when you registered your application.
• InitiateOAuth: Set to to have the driver manage the OAuth token exchange and refresh automatically.

See the Getting Started chapter of the help documentation for a guide to creating a custom OAuth app and using OAuth.

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 Anaplan 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 Anaplan 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 Anaplan Source]
Driver = CData ODBC Driver for Anaplan
Description = My Description
OAuthClientId = your_client_id
OAuthClientSecret = your_client_secret
CallbackURL = your_callback_url
Region = US1
InitiateOAuth = GETANDREFRESH

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

cdata.odbc.anaplan.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 Anaplan data that enables you to query live Anaplan data as an Oracle database.

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

   initmyanaplandb.ora

   HS_FDS_CONNECT_INFO = "CData Anaplan 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 = myanaplandb)
    (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 = myanaplandb)
    (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

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

4. Restart the listener.

5. Test the configuration with the following command:

   tnsping myanaplandb

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

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

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

SELECT * from "Sales"@myanaplandb WHERE Value = '100';
