3장. Coherence Examples 실행

수상한 김토끼 2022. 5. 16. 17:12

안녕하세요.

'수상한 김토끼' 입니다.

2장의 설치에 이어 Oracle의 in-memory 캐시 솔루션인 Coherence 예제를 실행해 보겠습니다.

이 블로그 글은 미들웨어 경험이 없으신 분들도 쉽게 따라 하실 수 있도록 쉽게 작성하는 것이 목표입니다.

설명을 보고 진행하시다가 궁금하신 내용은 댓글로 문의하시면 가능한 범위 내에서 알려 드리도록 하겠습니다.

1. Coherence Examples

코히어런스가 무엇이며 어떻게 사용하는지를 알아보려면 함께 제공 된 예제를 실행해 보며 확인해 보는게

가장 좋을 것으로 판단되어 코히어런스 설치 완료 후 예제에 대해 알아보려고 합니다.

관련 내용은 공식 문서를 통해 자세히 알아보실 수 있습니다.

https://docs.oracle.com/middleware/12213/coherence/install/running-coherence-examples.htm#COHIN5885

Running the Coherence Examples

ObserverExample demonstrates how to use a MapListener to monitor cache events such as when cache data has been inserted, updated, and removed. There is no immediate output when this example is run. The registered listener outputs the entry when it is inser

2. Coherence Examples build

코히어런스 예제를 실행하기 위해서는 구성 된 환경에 맞게 build를 수행해야 합니다.

예제를 실행하기 위해서는 $JAVA_HOME과 $COHERENCE_HOME 변수가 지정되어 있어야 하며

다음과 같이 지정 및 확인이 가능합니다.

[coherence@coherence ~]$ export COHERENCE_HOME=/home/coherence/coherence14c
[coherence@coherence ~]$ export JAVA_HOME=/home/coherence/jdk1.8.0_321
[coherence@coherence ~]$ env | grep _HOME
COHERENCE_HOME=/home/coherence/coherence14c
JAVA_HOME=/home/coherence/jdk1.8.0_321

예제 중 첫번째 contacts를 build 해 보겠습니다.

build는 $COHERENCE_HOME/coherence/examples/java/bin 경로의 build 파일을 이용하며

build <예제명> 으로 수행합니다.

Please refer to readme.txt for instructions on how to run the contacts example

코히어런스가 정상적으로 설치 되었으며, $JAVA_HOME과 $COHERENCE_HOME이 정상적으로 지정되어 있으면 위와 같이 빌드가 마무리 됩니다.

해당 예제를 실행하는 방법은 다음과 같습니다.

3. Coherence Examples Run

코히어런스 예제는 다음 2단계를 통해 실행할 수 있습니다.

1. $COHERENCE_HOME/coherence/examples/java/bin 경로의 run-cache-server 실행
2. $COHERENCE_HOME/coherence/examples/java/bin 경로의 run <예제명> 실행

2단계에서 build한 contacts 예제를 실행 해 보겠습니다.

예제가 로드 되었고 10,000개의 연락처를 cache에 add 하는 과정이 성공하였습니다.

이와 같이 사용 환경(Java, C++ 등)에 맞게 example을 build하여 실행 해 보실 수 있으니 다른 예제들도 수행 해 보시고

상황에 맞는 샘플을 찾아 적용해 보시면 좋을 것 같습니다.

이번 장은 이정도로 마무리하겠습니다. 여러 유용한 예제가 있으니 꼭 확인 해 보시길 바랍니다.

다음 장에서는 contacts 예제 소스를 보며 코히어런스가 어떤 방식으로 동작하는지 알아보도록 하겠습니다.
