Tomcat 調節緩衝與記憶體參數

Question

Bug1: Tomcat記憶體大小不足。

Bug2:

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

Solution

Bug1:建議更改Tomcat的setenv.sh 或 setclasspath.sh，加入：JAVA_OPTS='-Xms【初始化記憶體大小】 -Xmx【可以使用的最大記憶體】'

另外，可以看下JVM設定-記憶體-heap。簡單的深入瞭解下JVM原理。

Bug2:tomcat 中context.xml 設定檔的 <Context></Context>中加入<Resources cachingAllowed="true" cacheMaxSize="100000" />
