How to Download and Install Oracle JDBC Driver Type 4
Oracle JDBC driver type 4 is a Java library that implements the JDBC API and allows Java applications to connect to Oracle Database. Oracle JDBC driver type 4 supports JDK8, JDK11, and JDK17 and implements JDBC 4.2 and JDBC 4.3 specifications. It also provides features such as Universal Connection Pool (UCP), Reactive Streams Ingest (RSI), Application Continuity (AC), Transparent Application Failover (TAF), and more.
To download and install Oracle JDBC driver type 4, you need to follow these steps:
Go to the JDBC and UCP Downloads page on the Oracle website.
Select the version of Oracle Database that you want to connect to, such as 23c, 21c, 19c, 18c, or 12.2.
Download the jar file that matches your JDK version, such as ojdbc11.jar for JDK11 and JDK17 or ojdbc8.jar for JDK8 and JDK11.
Optionally, you can also download the companion jars, such as ucp.jar for Universal Connection Pool or rsi.jar for Reactive Streams Ingest.
Copy the jar files to a directory of your choice on your machine.
Add the jar files to your classpath or modulepath depending on your Java application.
You can now use the Oracle JDBC driver type 4 to connect to Oracle Database from your Java application.

Oracle JDBC driver type 4 is a thin driver that does not require any native libraries or Oracle client software to be installed on the client machine. It communicates directly with the Oracle Database server using the Oracle Net protocol. This makes it easy to deploy and maintain, as well as improving performance and scalability.
Oracle JDBC driver type 4 also supports advanced features of Oracle Database, such as JSON data type, sharding, pluggable databases, in-memory processing, and more. It enables Java applications to leverage the power and flexibility of Oracle Database in a standard and portable way.
Oracle JDBC driver type 4 is compatible with various frameworks and tools that use JDBC, such as Spring Boot, Hibernate, Apache Tomcat, Eclipse, NetBeans, and more. It also integrates with Oracle Cloud services, such as Oracle Autonomous Database and Oracle Database Cloud Service. It allows Java applications to connect to Oracle Database in the cloud with ease and security.
Oracle JDBC driver type 4 is one of the four types of JDBC drivers defined by the JDBC specification. The other types are:
Type 1: JDBC-ODBC bridge driver. This driver uses the ODBC driver installed on the client machine to connect to the database. It is not recommended for production use, as it is slow, platform-dependent, and does not support all JDBC features.
Type 2: Native-API driver. This driver uses native libraries of the database vendor to connect to the database. It requires the installation of the database client software on the client machine. It is faster than type 1 driver, but still platform-dependent and not fully JDBC compliant.
Type 3: Network-protocol driver. This driver uses a middleware server that converts JDBC calls into the database-specific protocol. It does not require any database client software or native libraries on the client machine. It is platform-independent and JDBC compliant, but adds an extra layer of network communication and processing overhead.
Oracle JDBC driver type 4 is the preferred type of driver for Java applications that connect to Oracle Database, as it offers the best performance, scalability, compatibility, and security. It is also the only type of driver that supports all Oracle Database features and versions. aa16f39245
