Creating ODBC (Open Database connectivity)Connection Informatica

Enter Data Source Name.

Enter Description.

TNS service name (XE default for Oracle 10g Database).

Enter User ID.

Test connection and enter username and password of the Oracle database as shown below. Finally click on Okbutton.

Informatica always recommends to use Datadirect drivers for importing the source and targets. To add ODBCconnection using Datadirect drivers follow the steps given below.

Creating source ODBC connection.

To create new ODBC source connection, click on Add button.

Select DataDirect 7.1 Oracle Wire protocol driver for which you want to set up a data source.

Click on Finish button.

Enter the following details to create new ODBC connection.

Data Source Name : SCOTT_ODBC_Oracle.

Host : localhost.Port Number : 1521.SID : ORCL.

SID : ORCL.

Click on Test connect, now a new window will be opened where user must enter username and password.Enter username as SCOTT.Password : Tiger.

Now click on OK button to test connection and message will be displayed as shown below.

We have created ODBC connection for source successfully, now create ODBC connection for Target as shownbelow.

Creating Target ODBC connection

Enter Data Source name as Batch10am_ODBC_Oracle.

Host : localhost.Port : 1521.SID : tutorialkart.

Click on Test connect button and enter user name and password and finally click on Ok button.
