DBCP Connection Pooling Example

DBCP Connection Pooling Example exaplains about how to create and configure a Connection pool using DBCP Datasource

Many Apache projects support interaction with a relational database, DBCP one among them.

Creating a new connection for each user can be time consuming (often requiring multiple seconds of clock time), in order to perform a database transaction that might take milliseconds. Opening a connection per user can be unfeasible in a publicly-hosted Internet application where the number of simultaneous users can be very large. Accordingly, developers often wish to share a "pool" of open connections between all of the application's current users.

The number of users actually performing a request at any given time is usually a very small percentage of the total number of active users, and during request processing is the only time that a database connection is required. The application itself logs into the DBMS, and handles any user account issues internally

C3P0 Connection Pooling Example

C3P0 Connection Pooling Example exaplains about how to create and configure a Connection pool using C3P0 Datasource

Creating and establishing a database connections are relatively very expensive because of establishing a network connection, initializng database session, authorization in the back end database etc.

Due to this issues, it is good practice to use a connection pool in your applications in order to increase the performance and scalability. By using Connection Pool, you can re-use already existing connections and prepared statements, so that you can avoid the cost of establishing the connection.

C3P0 is an easy-to-use library for augmenting traditional (DriverManager-based) JDBC drivers with JNDI-bindable DataSources, including DataSources that implement Connection and Statement Pooling, as described by the jdbc3 spec and jdbc2 std extension.

BoneCP Connection Pooling Example

BoneCP Connection Pooling Example exaplains about how to create and configure a Connection pool using BoneCP Datasource

Creating and establishing a database connections are relatively very expensive because of establishing a network connection, initializng database session, authorization in the back end database etc.

Due to this issues, it is good practice to use a connection pool in your applications in order to increase the performance and scalability. By using Connection Pool, you can re-use already existing connections and prepared statements, so that you can avoid the cost of establishing the connection.

BoneCP is a fast, free, open-source, Java database connection pool (JDBC Pool) library. If you are familiar with C3P0 and DBCP then you already know what this means. For the rest, this is a library that will manage a database connection for you to get faster database access in your application

EclipseLink JPA With MySQL

EclipseLink JPA With MySQL explains step by step details of setting / configuring Java Persistence (JPA) With EclipseLink And MySQL

How To Configure EclipseLink (JPA) With MySQL Database?

Java Persistence API (JPA), is a standard interface which wraps different ORM tools such as  Hibernate, EclipseLink, OpenJPA etc.

ie; you can able to change Hibernate implementation to EclipseLink implementation without changing the code base.

On this standalone JPA Example, we are using EclipseLink With MySQL Database

If you want to configure EclipseLink (JPA) With Oracle Database, you can follow Configure EclipseLink (JPA) With Oracle Database

EclipseLink is popular open source ORM (Object Relation Mapping) tool for Java platform, for mapping an entity to a traditional relational database like Oracle, MySQL etc
