Tomcat 调节缓存与内存参数

Question

Bug1: Tomcat内存大小不足。

Bug2:

cache because there was insufficient free space available after evicting expired cache entries - consider increasing the maximum size of the cache

---

Solution

Bug1:
建议更改Tomcat的setenv.sh 或 setclasspath.sh，加入：
JAVA_OPTS='-Xms【初始化内存大小】 -Xmx【可以使用的最大内存】'

另外，可以看下JVM设置-内存-heap。简单的深入了解下JVM原理。

Bug2:
tomcat 中context.xml 配置文件的 <Context></Context>中加入
<Resources cachingAllowed="true" cacheMaxSize="100000" />
