DCN stands for Database Change Notification. It is a feature provided by Oracle Database that allows applications to receive notifications when certain data changes occur in the database. This feature is particularly useful for applications that need to be notified immediately when changes occur in the database.

Java DCN is a Java API provided by Oracle that allows Java applications to register for database change notifications. The Java DCN API provides a simple interface for registering and receiving notifications, making it easy for Java developers to integrate this functionality into their applications.

To use Java DCN, you first need to enable database change notification in the Oracle Database. This can be done using the DBMS_CHANGE_NOTIFICATION package. Once enabled, you can use the Java DCN API to register for notifications and receive them in your Java application.

Overall, Java DCN is a powerful feature that can greatly enhance the functionality of your Oracle database applications. By allowing your applications to receive notifications in real-time, you can create more responsive and efficient applications that can react quickly to changes in your database.
