Lot of times you might be required to use database connections in an effective way in a standalone Java program. But mostly people use the traditional way of creating a new connection each time and closing it when finished. There is always a better way. In this section Vinod Kumar Kayartaya explains how to create a standlone database connection pool. Connection pooling is a mechanism to create and maintain a collection of JDBC connection objects. The primary objective of maintaining the pool of connection object is to leverage re-usability. A new connection object is created only when there are no connection objects available to reuse.

2012-08-09 1 connection pool 1.1 INTRODUCTION In actual development, "get Connection" or "release resources" are two processes that consume system resources very much. In order to solve this kind of performance problem, we usually use Connection pool technology to share Connection. In this way, we don't UTF-8 Unable to initialize JDBC BasicDataSource Connection Pool through REST API. Jira Development.

The difference is that DBCP will pool connections to the database instead of creating a new connection every time one is requested. We have also set a parameter here called initialSize. This tells DBCP that we want three connections in the pool when it is created.

Hi Team, I am unable to initialize JDBC BasicDataSource Connection Pool for external database in JIRA plugin through REST API. The Tomcat connection pool offers a few additional features over what most other pools let you do: initSQL - the ability to run an SQL statement exactly once, when the connection is created; validationInterval - in addition to running validations on connections, avoid running them too frequently.; jdbcInterceptors - flexible and pluggable interceptors to create any customizations around the The difference is that DBCP will pool connections to the database instead of creating a new connection every time one is requested. We have also set a parameter here called initialSize. This tells DBCP that we want three connections in the pool when it is created.

PoolableDataSource implements the DataSource interface using a provided ObjectPool. PoolingDataSource take cares of connections and ObjectPool take cares of holding and counting this object. In this video you will learn how to create and configure a Connection pool using DBCP Datasource using a demo project. Below is the GitHub link to download s IntialSize is the initial size of the connection pool. It is given as 5 so initially 5 connections will be created and stored in the pool. In this example Spring JdbcTemplate is used to query the DB. If you are using Spring XML configuration then configuration for DataSource and JDBCTemplate is as follows.
