I have read a lot about hikariCP and how it is "the fastest connection pool" and there is no deadlock reported with it. But when I compared it with tomcat-jdbc I get almost the same response times for both (if not tomcat-jdbc is faster). Further more I got an Exception when using hikariCP, stack trace can be found below. I feel that I did not configure the connection pool correctly.
note: my application should accept up to 70 transactions per second.
I am using:
HikariCP-1.4jdk 1.7 Spring Framework 3.2 Hibernate 4
and this is my HikariCP configuration:
<bean id="hikariConfig" class="com.zaxxer.hikari.HikariConfig">
<property name="poolName" value="springHikariCP" />
<property name="maximumPoolSize" value="7"/>
<property name="idleTimeout" value="9000"/>
<property name="connectionTimeout" value="120000"/>
<property name="jdbcUrl" value="${app.jdbc.url}"/>
<property name="username" value="${app.jdbc.username}"/>
<property name="password" value="${app.jdbc.password}"/>
<property name="driverClassName" value="${app.jdbc.driverClassName}" />
</bean>
<!-- HikariCP configuration -->
<bean id="dataSource" class="com.zaxxer.hikari.HikariDataSource" destroy-method="close">
<constructor-arg ref="hikariConfig" />
</bean>
the stak trace:

I started to get this exception when I made SessionFactory as static property. I don't get this exception right away when I push code to AWS server. I get it after few days. And when I get it I keep on getting it. Exception goes away when I restart AWS server.
Here is my code...
public List<E> getAll(Class<E> c) {
if (busUtil.iSessionFactory == null)
busUtil.loadSessionFactory();
Session session = busUtil.iSessionFactory.openSession();
List<E> t = null;
try {
session.beginTransaction();
t = session.createCriteria(c).list();
session.getTransaction().commit();
} catch (Exception e) {
e.printStackTrace();
new AppLogger().log("Exception" + busUtil.getStackTrace(e) , busConstant.SeveritySevere, new Object() {
}.getClass().getEnclosingMethod().getName());
session.getTransaction().rollback();
} finally {
session.close();
}
return t;
}
This is what I found in my logs.

Well one way to get rid this exception is to catch this exception and reload SessionFactory as this started happening when I made SessionFactory as static property.
But does anybody know why am I getting this exception?
Any help is appreciated. Thanks
As Hibernate's session-factory documentation states: "Hibernate's own connection pooling algorithm is, however, quite rudimentary. It is intended to help you get started and is not intended for use in a production system".
One of the reasons is that Hibernate doesn't test connection health. That means long-running connections on imperfect networks tend towards failure, as you are seeing.
c3p0 works well with Hibernate and allows you to easily configure max connection age and test connection health.

Can anyone help me with this

i have not yet mentioned any maximum connections
You need to configure connection pooling:
<property name="hibernate.dialect">org.hibernate.dialect.PostgreSQLDialect</property>
<property name="hibernate.connection.url">jdbc:postgresql://10.51.33.60:5432/ddddd</property>
<property name="hibernate.connection.username">abc</property>
<property name="hibernate.connection.password">abc</property>
<property name="hibernate.connection.driver_class">org.postgresql.Driver</property>
<!--connection pool settings-->
<property name="hibernate.c3p0.min_size">5</property>
<property name="hibernate.c3p0.max_size">20</property>
Make sure you include hibernate-c3p0 dependency too:
<dependency>
<groupId>org.hibernate</groupId>
<artifactId>hibernate-c3p0</artifactId>
<version>${hibernate.version}</version>
</dependency>
I use Spring remoting via JMS like that:
Client
<bean id="requestQueue" class="org.apache.activemq.command.ActiveMQQueue">
<constructor-arg value="request"/>
</bean>
<bean id="dispatcher"
class="org.springframework.jms.remoting.JmsInvokerProxyFactoryBean">
<property name="serviceInterface" value="x.Dispatcher"/>
<property name="connectionFactory" ref="connectionFactory"/>
<property name="queue" ref="requestQueue"/>
</bean>
Server
<bean id="requestQueue" class="org.apache.activemq.command.ActiveMQQueue">
<constructor-arg value="request"/>
</bean>
<bean id="dispatcher" class="org.springframework.jms.remoting.JmsInvokerServiceExporter">
<property name="serviceInterface" value="x.Dispatcher"/>
<property name="service">

<property name="connectionFactory" ref="connectionFactory"/>
<property name="destination" ref="requestQueue"/>
<property name="concurrentConsumers" value="10"/>
<property name="messageListener" ref="dispatcher"/>
</bean>
And its work fine. But if method on server took's more that 30 serconds I have exceptions and server stops process any other requests.

Can you recomend how to avoid this situation? Thanks!
I'm trying to do SpringMVC with JDBC Template.(SQL SERVER 2008 Database is used)
I inculded all jars needed to connect database.
Here is my DB connection bean coding
<!-- declare datasource bean -->
<bean id="dataSource"
class="org.springframework.jdbc.datasource.DriverManagerDataSource">
<property name="driverClassName" value="net.sourceforge.jtds.jdbc.Driver" />
<property name="url" value="jdbc:jtds:sqlserver://127.0.0.1:1098/userdb" />
<property name="username" value="root" />
<property name="password" value="root" />
</bean>
When i try to connect the Database, i got this error.
SEVERE: Servlet.service() for servlet [spring] in context with path [/SpringJDBCTemplate] threw exception [Request processing failed; nested exception is org.springframework.jdbc.CannotGetJdbcConnectionException: Could not get JDBC Connection; nested exception is java.sql.SQLException: Network error IOException: Connection refused: connect] with root cause

Please help me to resolve the error.
Please click here to get my full coding.
It looks like that your DB connection URL is not right or DB server is not available. Could you please verify that by logging using some client tool?

I had the same problem, hope my solution work for you too:
1: since you're using hibernate-c3p0-4.1.10.Final.jar, your provider_class should be:
<property name="connection.provider_class">org.hibernate.connection.C3P0ConnectionProvider</property>
from Error Caused by: org.hibernate.HibernateException: Could not instantiate connection provider [org.connection.C3P0ConnectionProvider]
Also, make sure you include both
c3p0-0.9.1.jar and hibernate-c3p0-4.2.1.Final.jar (should be in the same folder "\hibernate-release-4.2.1.Final\lib\optional\c3p0\" )
I ended up downloading the latest Hibernate release (4.2.1) here http://planet.jboss.org/post/hibernate_orm_4_2_1_final_and_4_1_12_final_released
and updating all the hibernate related jars in my project to get it to work properly, since the download link in eclipse only has the 3.6.0 Final version (JBoss Hibernate - http://download.jboss.org/jbosstools/updates/stable/)
Add the above lirary jar files found in your hibernate distribution lib directory
