Configure the CData JDBC Driver for Teradata in a Connection Pool in Tomcat

The CData JDBC Drivers support standard JDBC interfaces to integrate with Web applications running on the JVM. This article details how to connect to Teradata data from a connection pool in Tomcat.

Connect to Teradata Data through a Connection Pool in Tomcat

1. Copy the CData JAR and CData .lic file to $CATALINA_HOME/lib. The CData JAR is located in the lib subfolder of the installation directory.
2. Add a definition of the resource to the context. Specify the JDBC URL here.

   To connect to Teradata, provide authentication information and specify the database server name.

   • User: Set this to the username of a Teradata user.
   • Password: Set this to the password of the Teradata user.
   • DataSource: Specify the Teradata server name, DBC Name, or TDPID.
   • Port: Specify the port the server is running on.
   • Database: Specify the database name. If not specified, the default database is used.

   Built-in Connection String Designer

   For assistance in constructing the JDBC URL, use the connection string designer built into the Teradata JDBC Driver. Either double-click the JAR file or execute the jar file from the command-line.

   java -jar cdata.jdbc.teradata.jar

   Fill in the connection properties and copy the connection string to the clipboard.

   You can see the JDBC URL specified in the resource definition below.

   <Resource name="jdbc/teradata" auth="Container" type="javax.sql.DataSource" driverClassName="cdata.jdbc.teradata.TeradataDriver" factory="org.apache.tomcat.jdbc.pool.DataSourceFactory" url="jdbc:teradata:User=myuser;Password=mypassword;Server=localhost;Database=mydatabase;" maxActive="20" maxIdle="10" maxWait="-1" />

   To allow a single application to access Teradata data, add the code above to the context.xml in the application's META-INF directory.

   For a shared resource configuration, add the code above to the context.xml located in $CATALINA_BASE/conf. A shared resource configuration provides connectivity to Teradata for all applications.

3. Add a reference to the resource to the web.xml for the application. Teradata data JSP jdbc/Teradata javax.sql.DataSource Container
4. Initialize connections from the connection pool: Context initContext = new InitialContext(); Context envContext = (Context)initContext.lookup("java:/comp/env"); DataSource ds = (DataSource)envContext.lookup("jdbc/Teradata"); Connection conn = ds.getConnection();
