What is a Type 2 driver?

Type 2 drivers use a native API to communicate with a database system. Java native methods are used to invoke the API functions that perform database operations. Type 2 drivers are generally faster than Type 1 drivers. Type 2 drivers need native binary code installed and configured to work.

• Type-3 driver or Network Protocol driver.
• Type-4 driver or Thin driver.

What is difference between JDBC Type 2 and Type 4 in Java?

Type 2: Requires the DB2 Client is also installed on the same server as the JDBC driver because the driver is simply a front-end to the DB2 Client. It points to the alias you configured on the Client for your database, similar to an ODBC driver. Type 4: Connects to the database on server directly via the hostname/port.

Which JDBC driver is efficient?

Which driver is efficient and always preferable for using JDBC applications? Type 4 Driver is a Database-Protocol Driver(Pure Java Driver). Its implementation allows the conversion of JDBC calls directly into a vendor-specific database protocol.

Which driver should be used?

Which Driver should be Used? If you are accessing one type of database, such as Oracle, Sybase, or IBM, the preferred driver type is 4. If your Java application is accessing multiple types of databases at the same time, type 3 is the preferred driver.

Which type of JDBC driver is the fastest one?

JDBC Net pure Java driver
Which type of JDBC driver is the fastest one? JDBC Net pure Java driver(Type 4) is the fastest driver because it converts the JDBC calls into vendor specific protocol calls and it directly interacts with the database.

What are the different types of JDBC drivers?

There are 4 types of JDBC drivers:

• JDBC-ODBC bridge driver.
• Native-API driver (partially java driver)
• Network Protocol driver (fully java driver)
• Thin driver (fully java driver)

Which JDBC driver is best?

For most applications, the best choice is a pure Java driver, either Type 3, Type 4, or even Type 5.

• Type 5 JDBC drivers (such as DataDirect JDBC drivers) offer advanced functionality and superior performance over other driver types.
• Type 4 drivers are the most common and are designed for a particular vendor’s database.
