问题 I have tried C3po library for connection pooling but I am gettting errors such as abstractMethodError() for my code I then decided to go with the tomcat pooling thing.

假如想象 提交于 2019-12-11 09:58:03
问题 I've used jdbcpool 7.0.47 on grails app with version 2.2.4. When i checked the threaddump it shows that lots of "MySQL Statement Cancellation Timer" are in waiting state. I've also tried moving the jdbc connector to tomcat/lib but it start to give some date issues with mysql. So any other way to kill those threads 回答1: Ok evaluating all the params of connection pooling it seems validationQueryTimeOut was causing all this issue. After removing that param everything is normal. Now my working

问题 I recently upgraded my NetBeans IDE from v7.3 to v8 and all of a sudden my application throws an exception at server startup while connecting to DB. The only difference between these two versions of IDE are that the later one is using Tomcat 8. Exception Log: javax.naming.NamingException: Could not load resource factory class [Root exception is java.lang.ClassNotFoundException: org.apache.tomcat.dbcp.dbcp.BasicDataSourceFactory] at org.apache.naming.factory.ResourceFactory.getObjectInstance

Is “Tomcat 7 JDBC Connection Pool” good enough for production? And how is it compare to BoneCP?

问题 Our site get roughly 1M pv/day, and we use Tomcat for sure. I couldn't find much information about jdbc-pool, not sure if it's stable enough for production. Anyone got experience on it? and any configuration/tuning stuff for reference? As someone mentioned, BoneCP might be another choice. But seems it's discontinued (so sad...). Would it be a better choice? btw, HikariCP is too young, I would keep an eye on it as it's the latest/fastest CP so far I found. Thanks for any advice. 回答1: I'm one

PreparedStatement Pool with Connection Pool [duplicate]

Possible Duplicate: Prepared statement pooling in dbcp I am building a web application that uses Tomcat's Database connection pooling mechanism for its internal use. I am trying to pool the prepared statements as well so that the application is more efficient in retrieving data. From what I understand, connections are returned to the pool when the connection, resultset and statements are closed. If appropriate flags are set, abandoned connections are also closed and returned to the pool. Closing a connection means releasing all database cursors and cached statement including prepared
