tomcat6

问题 I currently have an application deployed using Tomcat that interacts with a Postgres database via JDBC. The queries are very expensive, so what I'm seeing is a timeout caused by Tomcat or Apache (Apache sits in front of Tomcat in my configuration). I'm trying to limit the connections to the database to 20-30 simultaneous connections, so that the database is not overwhelmed. I've done this using the \.. configuration, setting maxActive to 30 and maxIdle to 20. I also bumped up the maxWait. In

问题 I'm working with a grails application deployed in tomcat6, and I want to be able to enable or disable server side page caching on a "page by page" basis. In other words, I want to be able to specify, "Cache page A, but do not cache pages B and C." Is such a thing possible? If so, what is the best way to do this? Thanks in advance. 回答1: The Spring Cache plugin lets you cache controller actions and service method calls, so you could annotate the cacheable pages/actions and leave the ones that

问题 I've faced with strange tomcat6 behavior. Tomcat uses jar files from both /usr/share/tomcat6/lib and /usr/share/java . It's not good for me because a also have installed maven and /usr/share/java contains few versions of each java library and some applications cannot start because they see all version of libraries. How I can disable using of /usr/share/java by Tomcat6? p.s. I use Ubuntu 13.04. 来源： https://stackoverflow.com/questions/20453076/tomcat6-libs-and-usr-share-java-on-ubuntu

问题 I have deployed two WAR's in a Tomcat6 server, Say for example WAR-A , WAR-B in Context-A and Context-B respectively.
