Use the Oracle ODBC Gateway and Heterogeneous Services technology to access Raisers Edge NXT 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 Raisers Edge NXT to create a database link from Raisers Edge NXT to Oracle and to query Raisers Edge NXT data through the SQL*Plus tool. You can also create the database link and execute queries from SQL Developer.
Connect to Raisers Edge NXT as an ODBC Data Source
Information for connecting to Raisers Edge NXT follows, along with different instructions for configuring a DSN in Windows and Linux environments.
Before establishing a connection, supply the SubscriptionKey, found in the Blackbaud Raiser's Edge NXT Profile.
Authenticating to Raiser's Edge NXT
Blackbaud Raiser's Edge NXT uses the OAuth authentication standard. You can connect to without setting any connection properties using the embedded OAuth credentials.
Alternatively, you can authenticate by creating a custom app to obtain the OAuthClientId, OAuthClientSecret, and CallbackURL connection properties.
See the Help documentation for an authentication guide.
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 Raisers Edge NXT 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 Raisers Edge NXT 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 RaiserEdgeNXT Source]
Driver = CData ODBC Driver for Raisers Edge NXT
Description = My Description
SubscriptionKey = MySubscriptionKey
OAuthClientId = MyOAuthClientId
OAuthClientSecret = MyOAuthClientSecret
CallbackURL = http://localhost:33333
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 Raisers Edge NXT data just as you would an Oracle database. Set the following properties when working with Raisers Edge NXT 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-raiseredgenxt/lib/cdata.odbc.raiseredgenxt.ini in a text editor and set the encoding.
cdata.odbc.raiseredgenxt.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 Raisers Edge NXT data that enables you to query live Raisers Edge NXT data as an Oracle database.
-
Create the file initmyraisersedgenxtdb.ora in the folder oracle-home-directory/hs/admin and add the following setting:
initmyraisersedgenxtdb.ora
HS_FDS_CONNECT_INFO = "CData RaiserEdgeNXT 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 = myraisersedgenxtdb) (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 = myraisersedgenxtdb) (ORACLE_HOME = your-oracle-home) (PROGRAM = hsodbc) ) )
-
Add the connect descriptor below in tnsnames.ora, located in oracle-home-directory/NETWORK/admin:
tnsnames.ora
myraisersedgenxtdb = (DESCRIPTION= (ADDRESS=(PROTOCOL=tcp)(HOST=localhost)(PORT=1521)) (CONNECT_DATA=(SID=myraisersedgenxtdb)) (HS=OK) )
- Restart the listener.
Test the configuration with the following command:
tnsping myraisersedgenxtdb
-
Open SQL*Plus and create the database link with the command below:
CREATE DATABASE LINK myraisersedgenxtdb CONNECT TO "user" IDENTIFIED BY "password" USING 'myraisersedgenxtdb';
You can now execute queries in SQL*Plus like the one below (note the double quotation marks around the table name):
SELECT * from "Constituents"@myraisersedgenxtdb WHERE Type = 'Home';
