The following text describes how to write the URL in your applet, so that the applet connects to the Connection Manager and the Connection Manager connects with the database. If you want your applet to connect to a database running on a different computer, then you have the following options: These attributes are described in the following sections:. Alternatively, you can use the forName method of the java. Oracle needs three drivers to support different deployment options. This means that without these steps, your applet can connect only to a database that is running on the same host as the Web server.

This feature reduces round trips to the server.
Oracle jdbc thin discussion helped me resolve the issue I was struggling with for days. This following topics are covered in this chapter:. To allow requests from JDBC Thin clients to go through the firewall, you must do the following to the list of firewall rules: To package an applet, you will need your applet class files and the JDBC driver class files contained in the ojdbc5.
Here thhin an oraccle of oracle jdbc thin very simple CMAN.
ColdFusion MX: Configuring the Oracle JDBC thin driver
Closing the default connection might throw an exception in future releases of Oracle. These attributes are oracle jdbc thin in the following sections:.
The order in which you list the addresses is important. Please guide, is it possible to oracle jdbc thin a persistent Database connection and use it for all database access for all sessions in web application as separate connection may cause exhausting number of processes in oracle.
Features Specific to JDBC Thin
You can do this in the following ways:. Remember not to close the default Connection.
The format for that is: This property can also be oracle jdbc thin as a java property: This driver can be downloaded along with the Java oracle jdbc thin that is being run in a browser.

The following example describes the configuration illustrated in Figure This class provides a basic service for managing a set of JDBC drivers.

Oracle JDBC drivers allow you to accumulate inserts and updates of prepared statements and send them to the server oracle jdbc thin batches once it reaches a specified batch value. It also describes how your applet can connect to a database through a firewall.
