tangosol.coherence.localhost, tangosol.coherence.localport 옵션은 run.xml 에도 정의가 되어 있다.

Cache Server를 다중화 하는 경우, 각 Cache Server별로 다르게 설정하는 것을 run.xml이 아닌, 가장 우선순위가 높은 JVM Argument로 지정한다.

즉, Cache Server를 추가로 셋업하려면 위 옵션을 변경하면 된다.

그리고 run.xml 의 Well Known Address를 설정해야 한다. (참고: [[Coherence 3.7] run.xml 설명]](https://blog.naver.com/ks900331/221497889161))

4. WebLogic

WebLogic 인스턴스에 Coherence 3.7 을 Setup하기 위한 설명이다.

4.1 coherence.jar

${COHERENCE_HOME}/coherence.jar를 lib 디렉토리에 복제한다.

$ cp ${COHERENCE_HOME}/lib/coherence.jar ${WEBLOGIC_DOMAIN_HOME}/lib/

$ ls -al /sw/weblogic/11g/domains/base_domain/lib/coherence.jar
-rw-r--r-- 1 wasadm wasadm 7452777 Jan 23 15:53 /sw/weblogic/11g/domains/base_domain/lib/coherence.jar

4.2 coherence-web-spi.war

${COHERENCE_HOME}/coherence-web-spi.war 파일은 Shared Library이다.

WLS Admin Console을 통해서 Library로 배포한다.

export USER_MEM_ARGS="$USER_MEM_ARGS -Dtangosol.coherence.override=${COHERENCE_HOME}/lib/run.xml"

Cache Server와 다르게, localstorage=false를 설정하였다.

4.4 Web Application

어플리케이션의 weblogic.xml 에 Shared Library를 선언한다.
