connection-pooling

Recently I downloaded the JDBC driver for PostgreSQL from here . Since I'm using Java 1.7 JVM and it's written: If you are using the 1.6 or 1.7 JVM, then you should use the JDBC4 version. I download JDBC4. The problem is there exist no PoolingDataSource's in it. If you get JDBC3 you can use org.postgresql.jdbc3.Jdbc3PoolingDataSource or others as is seen here . Is there any pooling DataSource in JDBC4 that I don't know about, or what should I use instead? The only thing I found in JDBC4 is PGPoolingDataSource but I'm not sure if I'm supposed to use this because based on their Java doc message:

I am using Redis to store two databases : 0 and 1 via the Redis-py client library. I would like to create two connections for each database. Currently, I am doing this : >>> connection0 = redis.Connection(host = 'localhost', port = 6379, db = 0) >>> connection1 = redis.Connection(host = 'localhost', port = 6379, db = 1) >>> connection0.connect() However, I don't seem to find a way to create a Redis object from the connection. >>> store0 = redis.Redis(connection0) >>> store0.info() Traceback (most recent call last): File "<stdin>", line 1, in <module> File "/Library/Frameworks/Python.framework

I am using spring framework 3.2 with hibernate 4 , I get the above exception when sending a request after a long idle time on the local server ( apache-tomcat v7.0 ) and the database is located on remote server. After hours of search I came to that the problem comes from the connection pool. I tried number of connection pools but didn't find the satisfying solution. bellow is the current datasource on my spring-data file <bean id="dataSource" class="oracle.jdbc.pool.OracleDataSource" destroy-method="close"> <property name="connectionCachingEnabled" value="true" /> <property name="URL" value="$

We have a java server connecting to a MySQL 5 database usingHibernate as our persistence layer which is using c3p0 for DB connection pooling. I've tried following the c3p0 and hibernate documentation: Hibernate - HowTo Configure c3p0 connection pool C3P0 Hibernate properties C3P0.properties configuration We're getting an error on our production servers stating that: ... Caused by: com.mysql.jdbc.exceptions.jdbc4.MySQLNonTransientConnectionException: No operations allowed after connection closed.Connection was implicitly closed due to underlying exception/error: BEGIN NESTED EXCEPTION com.mysql

I am new to jboss and i have been asked to incorporate jboss connection pooling mechanism with an existing web application. Considering that a web application database layer is properly written i.e. all resultsets, statements and connections being closed properly when not needed, What all code changes i will have to make in my web app after i have configured the jboss datasource properly. Can anybody please point me to a tutorial or a code sample which uses jboss datasource in a web app. The pool in JBoss is all handled in the DataSource configuration. Here is the HowTo. The web app would have

I've got a Spring app that I believe uses DBCP connection pooling to connect to a MySql database. I say believe because this isn't an area I'm very strong in and I'm not positive if everything is set up correctly. I have no problems running the application and everything is working fine. The problem occurs overnight. The app is not heavily used and overnight it apparently loses it's connection to MySql. I looked into it and found out MySql has an 8 hour window and then it disconnects or whatever. I'm fine with this, but when a user attempts to log on in the morning, they get an error something
