Tomcat的启动关闭及日志说明 Tomcat的启动关闭及日志说明 阅读详情
项目部署在tomcat上，持续运行大概1-2个月左右，期间程序可正常运行，但是报错后tomcat就无法连接到数据库，只能看到登录界面。报错显示各种停止，最后跳到提示端口号被占用，但是除此tomcat启动外并无其他任何有关java的程序开启。
个人分析有可能是内存溢出或者数据库连接池的问题，但是具体原因和解决办法不知。
请各位大神帮忙分析一下，谢谢！

shell脚本监控tomcat服务运行状态，服务关闭后进行重启 最近在维护一个项目的时候，发现经常有tomcat运行一段时间后自动停掉的情况，影响了正常的生产交易，被逼无奈，在未找到tomcat自动关闭原因之前，还是得靠shell脚本来进行实时监控。如果发现tomcat没有运行，则执行startup.sh启动tomcat,以下贴出脚本源码。#!bin/sh date=`date +%Y-%m-%d_%H:%M:%S` ##tomcat的进程数,由于脚本名称为mo 阅读详情

一次tomcat自动关闭的bug解决

前言 最近一个运行了4年的javaee web项目，经常接到客户反馈系统无法打开。登录服务器查看服务，发现是tomcat自动关闭了。基本是3到4天发生一次。 运维人员开始以为是其他服务杀死了tomcat服务，没放在心上，解决方法就是直接重启tomcat。 最终捅了篓子，运维人员被客户投诉，扣了一个月的绩效。 解决这个bug兜兜转转来到了我这里。既然接到任务，那就开干，没有解决不了的bug。 系统的运行环境如下： tomcat6.0 32位jdk7.0 window server2003 32位，32G内存。 查看日志，如果tomcat闪崩，都会在tomcat的bin目录下生成以”
