1. JVM의 메타스페이스 크기 증가 

- Tomcat을 실행할 때 -XX:MaxMetaspaceSize 옵션 추가

#!/bin/bash

TOMCAT_HOME=/home/hosting_users/domain/tomcat
cd $TOMCAT_HOME/bin

# 메타스페이스 크기 설정
export CATALINA_OPTS="-XX:MaxMetaspaceSize=512m"

# Tomcat 중지 및 시작
./shutdown.sh
./startup.sh

# 로그 출력
tail -500f $TOMCAT_HOME/logs/catalina.out

 

2. Tomcat 캐시 크기 증가

- server.xml 파일에서 <Host> 태그 내에 maxCacheSize 속성을 추가하거나 수정

<Host ...>
    ...
    <Context>
        <Resources maxCacheSize="100000" />
    </Context>
</Host>
