Perhaps I was unclear what it is I'm trying to do. I have a connection pool set up under Tomcat 5.5, connecting to DB2 on an iSeries box using Tomcat's DBCP. It is set up for 30 connections. I am using Lambda Probe (a great open source Tomcat monitoring app) to monitor the datasources. It is

It is possible that whatever procedure is responsible for checking for abandoned connections only does so when there is actual need for a connection, similar to how a garbage collector works to reclaim memory. If there is no seeming stress on the connection resources then it would make sense not

I agree that is probably what is happening, since the application has gone idle. However, with garbage collection, while it will only reclaim memory when necessary, there is a way to force garbage collection. I am looking for a similar process with abandoned database connections. On 1/10/07,

How to forcibly close abandoned database connections?

2007-01-08 Thread David Uctaa
Tomcat provides the removeAbandoned and removeAbandonedTimeout parameters when setting up data sources in server.xml. But according to the documentation I've read, abandoned connections only get closed and recycled when available connections run low and new connections are requested. Is there a
