Create Informatica Mappings From/To an ODBC Data Source for Sybase

Informatica provides a powerful, elegant means of transporting and transforming your data. By utilizing the CData ODBC Driver for Sybase, you are gaining access to a driver based on industry-proven standards that integrates seamlessly with Informatica's powerful data transportation and manipulation features. This tutorial shows how to transfer and browse Sybase data in Informatica PowerCenter.

Connect to Sybase as an ODBC Data Source

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

To connect to Sybase, specify the following connection properties:

• Server: Set this to the name or network address of the Sybase database instance.
• Database: Set this to the name of the Sybase database running on the specified Server.

Optionally, you can also secure your connections with TLS/SSL by setting UseSSL to true.

Sybase supports several methods for authentication including Password and Kerberos.

Connect Using Password Authentication

Set the AuthScheme to Password and set the following connection properties to use Sybase authentication.

• User: Set this to the username of the authenticating Sybase user.
• Password: Set this to the username of the authenticating Sybase user.

Connect using LDAP Authentication

To connect with LDAP authentication, configure Sybase server-side to use the LDAP authentication mechanism.

After configuring Sybase for LDAP, you can connect using the same credentials as Password authentication.

Connect Using Kerberos Authentication

To leverage Kerberos authentication, begin by enabling it setting AuthScheme to Kerberos. See the Using Kerberos section in the Help documentation for more information on using Kerberos authentication.

You can find an example connection string below:

Server=MyServer;Port=MyPort;User=SampleUser;Password=SamplePassword;Database=MyDB;Kerberos=true;KerberosKDC=MyKDC;KerberosRealm=MYREALM.COM;KerberosSPN=server-name

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.

Linux

If you are installing the CData ODBC Driver for Sybase 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 Sybase Source]
Driver = CData ODBC Driver for Sybase
Description = My Description
User = myuser
Password = mypassword
Server = localhost
Database = mydatabase
Charset = iso_1

For specific information on using these configuration files, please refer to the help documentation (installed and found online).

Create a Linked Table to Products Data

Follow the steps below to create a linked table, which enables you to access live Products data.

Create the ODBC Connection

Follow the steps below to connect to Sybase in Informatica PowerCenter:

1. In the Informatica Developer tool connect to your repository and create a project.
2. In the Connection Explorer pane, right-click and click Create a Connection.
3. In the New Database Connection wizard that is displayed, enter a name and Id for the connection and in the Type menu select ODBC.
4. In the Connection String property, enter the DSN.

NOTE: If you are working in a Linux operating system, set the Driver Manager for Linux property to unixODBC 2.3.x.

Create the Sybase Data Object

After you have created an ODBC connection to Sybase, you can now access Sybase entities in Informatica. Follow the steps below to add Products entities to your project.

1. In the Object Explorer, right-click your project and then click New -> Data Object.
2. In the wizard that is displayed, select the Relational Data Object option.
3. Click the Browse button next to the Connection box and select the ODBC connection you created in the previous step.
4. Select the option to create a data object from an existing resource and click the Browse button next to the Resource box.
5. In the dialog that is displayed, clear the Show Default Schema Only option and expand the node for the ODBC connection. Select the entity that you want. 👁 The driver models Sybase entities as relational tables. (Salesforce is shown.)
   

You can now browse the table in the Data Viewer: Right-click the node for the table and then click Open. On the Data Viewer view, click Run.

👁 Table data and metadata in the Data Viewer. (Salesforce is shown.)

Create the Mapping

Follow the steps below to add the Sybase source to a mapping:

1. In the Object Explorer, right-click your project and then click New -> Mapping.
2. Expand the node for the Sybase connection and then drag the data object for the table onto the editor.
3. In the dialog that appears, select the Read option.

👁 The source Sybase table in the mapping. (Salesforce is shown.)

Follow the steps below to map Sybase columns to a flat file:

1. In the Object Explorer, right-click your project and then click New -> Data Object.
2. Select Flat File Data Object -> Create as Empty -> Fixed Width.
3. In the properties for the Sybase object, select the rows you want, right-click, and then click copy. Paste the rows into the flat file properties.
4. Drag the flat file data object onto the mapping. In the dialog that appears, select the Write option.
5. Click and drag to connect columns.

To transfer Sybase data, right-click in the workspace and then click Run Mapping.

👁 The completed mapping. (Salesforce is shown.)
