c3p0

I am connecting to MySQL over SSL from my Java application. I have configured MYSQL to support SSL and generated client certificates. I have imported server CA certificate and client certificate into keystore. This is how my code currently looks like String url = "jdbc:mysql://127.0.0.1:3306/MySampleDb? verifyServerCertificate =true&useSSL=true&requireSSL=true" System.setProperty("javax.net.ssl.keyStore","/home/cert/keystore"); System.setProperty("javax.net.ssl.keyStorePassword","password"); System.setProperty("javax.net.ssl.trustStore","/home/cert/truststore"); System.setProperty("javax.net

I got this error from the production code: com.mysql.jdbc.exceptions.jdbc4.CommunicationsException: The last packet successfully received from the server was36940 seconds ago.The last packet sent successfully to the server was 36940 seconds ago, which is longer than the server configured value of 'wait_timeout'. You should consider either expiring and/or testing connection validity before use in your application, increasing the server configured values for client timeouts, or using the Connector/J connection property 'autoReconnect=true' to avoid this problem. And now I'm trying to reproduce

I'm using C3P0 and the MS SQL JDBC 4 driver to automatically failover to a new database mirror when the database goes away. If it first connects to the principal DB, then the failover works and it switches seamlessly to the mirror DB. However, if the principal DB is down when the application starts, and the mirror DB is available to connect (tested with MSSQL Studio), then the application fails to start and fails to connect to the backup mirror. Here is the connection URL: jdbc:sqlserver://PRINCIPALDB;databaseName=app_space;port=99999;failoverPartner=MIRRORDB I have c3p0

Hi I have two web application under one tomcat. Both are using hibernate 3.2.1 and c3p0 0.9.1.2. While the second application gets deployed, I always get the following warning message. Tomcat: apache-tomcat-6.0.28 WARN 2010-11-06 19:04:37,270 A C3P0Registry mbean is already registered. This probably means that an application using c3p0 was undeployed, but not all PooledDataSources were closed prior to undeployment. This may lead to resource leaks over time. Please take care to close all PooledDataSources. Please help in this regard. Thanks in advance Goura To avoid the C3P0Registry from being

I'm new to c3op, and confused about the use of : c3p0.idle_test_period In this link : HowTo configure the C3P0 connection pool idleTestPeriod : Must be set in hibernate.cfg.xml (or hibernate.properties), Hibernate default: 0, If this is a number greater than 0, c3p0 will test all idle, pooled but unchecked-out connections, every this number of seconds. What is the purpose of this kind of test (idel, pooled connections), and the relationship between c3p0.idle_test_period and c3p0.timeout? The database server may close a connection on its side after a certain amount of time - causing some error
