[color=red]在windows系统下。
我将一个大的项目拷贝到tomcat/webapps该目录下，在启动tomcat时报内存溢出，也试过在bin/catalina目录下添加set JAVA_OPTS此内容，启动后结果还是一样报错，敬请帮忙 [size=xx-small][/size][/color]
以下是部分报错信息：

那你别把工程copy到webapps下啊.其他任何地方都可以..然后在 指过去,就可以了..
重新打包一下项目 rebuild
调整服务器启动时的内存分配。缺省服务器的内存容量，各个区的容量一般偏小，请根据自己的情况进行调整。
双击..\bin\tomcat5w.exe打开，点击java按钮，修改Inital memory pool和Maximum memory pool的大小。
如果还不行就配置系统环境变量：
变量名：JAVA_OPTS
变量值：-Xms64m -Xmx512m
根据自己的机器调整变量值的大小。
JAVA_OPTS没有设置对。你仔细看一下。
问题补充：
魔力猫咪 写道
JAVA_OPTS没有设置对。你仔细看一下。
我是将下面的内容设置在bin/cataline.bat文件中的
set JAVA_OPTS=-Xms800m -Xmx800m -XX:PermSize=128M -XX:MaxNewSize=256m -XX:MaxPermSize=256m
这种方式我曾经试过，但是不知道为什么不好用，你最好试试设置系统环境变量。
我用的是TOMCAT5.0,你看看有没有..\bin\tomcat6w.exe或者类似的文件。
配置下jvm大小
那就只能通过修改配置文件了。
Invocation of init method failed; nested exception is java.lang.OutOfMemoryError: PermGen space
已经很明确的告诉你 PermGen溢出了..你只要增加permGen大小就可以了..具体的配置就是
-XX:MaxPermSize=512m
如果你的工程连512m都不够,那么我觉得可能是死循环造成的..因为整个eclipse也就一百多m..
configure server ->server->tomcat->jdk->java VM下面方框里数据配置信息
我很好奇,你竟然连256m都不够..你可以开visualVM看看..具体的PermGen占了多少
就是你改过的bin/cataline.bat文件中的
set JAVA_OPTS=-Xms800m -Xmx800m -XX:PermSize=128M -XX:MaxNewSize=256m -XX:MaxPermSize=256m
修改后在管理，服务里面重新启动下
如果还不好用，建议换个其他版本的服务器
如果你是用eclipse跑的话,参考上面那位仁兄的位置,加上 -XX:MaxPermSize=512m 试试看.
你打开visualVM看看,这个配置是否生效了.visualVM就在jdk的bin目录..JVisualVM .
-Xms512m -Xmx1024m -XX:PermSize=128m -XX:MaxPermSize=256m
我是这样在服务器配置中进行设置的。
[quote]就是你改过的bin/cataline.bat文件中的
set JAVA_OPTS=-Xms800m -Xmx800m -XX:PermSize=128M -XX:MaxNewSize=256m -XX:MaxPermSize=256m
修改后在管理，服务里面重新启动下
如果还不好用，建议换个其他版本的服务器
[/quote]
上面这个方法是对的..至于这个修改是否生效,再说一次,打开visualVM看看
@Wind_ZhongGang 你们这个服务器配置,我的建议是 -Xms512m -Xmx1024m 这两个值设置成一样,否则在堆扩容或者降容的时候都会造成额外的full gc.而这个是完全可以避免的..
你把工程放到tomcat下,他需要加载这么多class类信息等等,所以造成的永久代溢出的..你不加载工程当然就不会有溢出.你能看到对应永久代的大小不..用visualVM
这句就是指向工程目录的,怎么会没加载哦.呵呵
晕,你在webapp下放着,又在server.xml里配置..会造成重复的..这个重复会不会出问题..我没试过..你可以试试把server.xml里的工程加载配置删除,直接启动,然后访问
这讲的很详细：
