What is JDBC class forName?

Use the Class. forName() method to load the driver. The forName() method dynamically loads a Java class at runtime. When an application calls the forName() method, the JVM (Java Virtual Machine) attempts to find the compiled form (the bytecode) that implements the requested class.

Which driver is most suitable for Oracle Database?

The best choice is to use Oracle JDBC thin driver.

Which version of Ojdbc should I use?

Which driver should I use? The best choice is to use Oracle JDBC thin driver. All the new enhancements and features are implemented only on JDBC Thin driver. If you are using a non-TCP/IP network you must use the OCI driver.

Why should we use class forName?

In general Class. forName is used to load the class dynamically where we doesn’t know the class name before hand. Once the class is loaded we will use newInstance() method to create the object dynamically. Lets consider that we have a class “Test”, and we make a call like Class.

How do I find the class forName?

Example 1

  1. import java.lang.*;
  2. public class ClassforNameExample1 {
  3. public static void main(String[] args) {
  4. try {
  5. Class classlldr = Class.forName(“java.lang.ClassLoader”); //lang class loader is passed as parameter.
  6. System.out.println(“Name of Class = ” + classlldr.getName()); //get the name of class.

What is the Oracle JDBC driver?

Which is the driver class for Oracle Database?

Driver class: The driver class for the oracle database is oracle.jdbc.driver.OracleDriver.

How does JDBC driver connect to Oracle Server?

If your JDBC client and Oracle server are running on the same machine, the OCI driver can use IPC (InterProcess Communication) to connect to the database instead of a network connection. An IPC connection is much faster than a network connection.

What kind of driver do I need for Oracle ODBC?

Oracle ODBC driver on Windows has been tested using MDAC version 2.8. See the unixODBC readme and INSTALL files for the list of files that are installed with unixODBC Driver Manager. The Oracle ODBC Driver supports all core API functionality and a limited set of Level 1 and Level 2 functionality.

How to connect to the Oracle 10g database?

Connection URL: The connection URL for the oracle10G database is jdbc:oracle:thin:@localhost:1521:xe where jdbc is the API, oracle is the database, thin is the driver, localhost is the server name on which oracle is running, we may also use IP address, 1521 is the port number and XE is the Oracle service name.
