Hello: I was using validationQuery in Tomcat 6 for JNDI datasources, so to check connections before borrowing to the caller And, about documentacion, testOnBorrow parameter is true by default
testOnBorrow - true or false: whether a connection should be validated using the validation query each time it is borrowed from the pool. Default: true http://tomcat.apache.org/tomcat-6.0-doc/jndi-resources-howto.html And all works fine Now , I want to use JDBC Pool with a new web application deployed on that Tomcat 6. So, I consider it as an standalone application, and I use org.apache.tomcat.jdbc.pool.DataSource class ( I use Spring-MyBatis to configure datasource , injecting it as a bean) I've read in Tomcat 7 JDBC pool documentation that testOnBorrow is false by default in this case Is it right ? Must I define testOnBorrow = true explicitly ? It's little bit strange that default values be different either access by JNDI or bean instantiation Should I use org.apache.tomcat.jdbc.pool.DataSourceFactory instead of org.apache.tomcat.jdbc.pool.DataSource ? My doubt is if one is better than other in performance terms Should I use META-INF/context.xml and to use <Resource> ? Thanks and regards
