我安装了tomcat 7，将我的JIRA项目版本从5.0升级到6.我将项目文件夹放在tomcat的webapps中。我运行这个localhost：8080 / jira 经过长时间运行后，它会抛出一些错误信息。请提前感谢您帮助我们解决此问题

Answer 1

更有用的解决方案是增加JAVA_OPTS变量中的值将下一行添加到Catalina.bat/Catalina.sh目录

中的bin文件

适用于Windows（Catalina.bat）

set JAVA_OPTS="-Xms1024m -Xmx10246m -XX:NewSize=256m -XX:MaxNewSize=356m -XX:PermSize=256m -XX:MaxPermSize=356m"

对于Unix（Catalina.sh）

export JAVA_OPTS="-Xms1024m -Xmx1024m -XX:NewSize=256m -XX:MaxNewSize=356m -XX:PermSize=256m -XX:MaxPermSize=356m"

Answer 2

有时在重新部署后，垃圾收集器无法销毁Tomcat上的某些对象并且空间不足。这些案例有很多原因：

如果使用某些CRUD对象 - 请在使用后检查是否全部关闭。
如果您的应用程序使用了其他库 - 有时这些库中的对象也无法销毁，例如MysqlConnector，Hibernate / C3p0或其他 - 尝试将这些库放在tomcat / lib文件夹上

使用“Java VisualVM”检查Tomcat，并在重新部署后检查permGen permGen Space的默认值通常也非常低，您可以使用以下javaVM参数增加它们

 -XX:PermSize=64M -XX:MaxPermSize=256m

您可以按照这些教程

添加-XX：+ CMSClassUnloadingEnabled -XX：+ UseConcMarkSweepGC到javaVM选项

Answer 3

使用-XX:PermSize={value}和-XX:MaxPermSize={value}通过JAVA_OPTS变量调整permgen的值，其中'value'是一个256m的字符串。

部署tomcat 7时出现PermGen Space错误？
