Context에서 auto reload 부분 제외 해야 하고..

dbcp connection pool 튜닝 필요 --> dbcp 말고 tomcat pool 사용

context.xml에 설정

<Resource name="jdbc/TestDB" auth="Container" type="javax.sql.DataSource"
               maxActive="100" maxIdle="30" maxWait="10000"
               username="javauser" password="javadude" driverClassName="com.mysql.jdbc.Driver"
               url="jdbc:mysql://localhost:3306/javatest"/>

애플리케이션 배포를 쉽게 하기 위해서, 위의 Context.xml은 war/META-INF/context.xml을 사용하는게 좋음

shared lib 처리 필요

JVM은 -server -Xms1024m -Xmx1024m -XX:NewSize=384m -XX:PermSize=128m + ParallelGC, GCThread=3, +PrintGCDetial

디렉토리 처리 (1 server , 1was를 기준으로 함)

tomcat 설치는 /usr/local/tomcat

JVM은 /usr/local/jvm

application은 /applications/war/

log는 /applications/log/access.log catalina.out 기타 application logs

기타 스크립트는 /applications/scripts

설정 파일 /appllications/properties

아니면

/product/j2ee/jdk

/product/j2ee/tomcat

/applications/j2ee/war

/applications/j2ee/logs

/applications/j2ee/scripts

/applications/j2ee/properties

아니면

/product/tomcat

/product/jdk

/product/tomcat7 (link)

/product/jdk1.6 (link)

/applications/tomcat/war

/applications/tomcat/logs/access.log, catalina.out

/applications/tomcat/scripts/deploy/fabfile

/applications/tomcat/scripts/logbackup/fabfile

/applications/tomcat/properties

boot up시 최신 war 파일을 repository에서 읽어오는 부분 추가

튜닝 하려면 한 2일 걸리겠네...
