Creates a JDBC connection factory for this data source. .dbcp.BasicDataSource Java Examples The following examples show how to use .dbcp.BasicDataSource. Closes and releases all idle connections that are currently stored in the connection pool associated with this data source. service line: 634Ĭom. DBCP 2 is based on Commons Pool 2 and provides increased performance, JMX support as well as numerous other new features compared to DBCP 1.x. Adds a custom connection property to the set that will be passed to our JDBC driver. threads.TaskThread$n line: 61Ĭom.writeActionMails line: 166Ĭom.doGet line: 50 net.NioEndpoint$SocketProcessor.doRun line: 1415 HttpHeaderSecurityFilter.doFilter line: 126 .dbcp BasicDataSource close Javadoc Closes and releases all idle connections that are currently stored in the connection pool associated with this data source.

Since: 2. This is not the only way to combine the commons-dbcp2 and commons-pool2 packages, but provides a one-stop solution for basic requirements. We restarted our application to prevent the "whole Tomcat down" issue from happening.Īt that time, we had many (~50) BLOCKED threads, most of them with a stack trace where the top line is like this (there are of course many different codepaths that use DB connections in the end, so the whole stack is always a bit different:Ĭom. line: 167Ĭom. line: 121Ĭom. line: 2356Ĭom. line: 2330Ĭom. Basic implementation of that is configured via JavaBeans properties. This in turn maxes out our Tomcat threads ( maxThreads here) eventually, bringing all instances effectively down, as no more threads can be created. Do not know if the information is correct or not. The only difference between these two can be found in this blog. Commons DBCP datasource class is .BasicDataSource. Tomcat DBCP datasource class is .dbcp.BasicDataSource.

New requests will hang (stack trace follows). The DB driver should be placed in tomcat/lib. Now if the issue happens, one application (server.xml entry) maxes out it connections. The examples are extracted from open source Java projects from GitHub.

These application run on the same Tomcat (9.0.17). This page provides Java code examples for .BasicDataSource.
