Redis 를 활용해서 Cache를 적용해보자..

우선 Redis Client는 http://www.redis.io/clients 에서 확인되는바와 같이 종류가 여러가지다.

그런데 Spring Data Redis 를 사용하면 별도의 Client가 필요 없네...(Interface만 있고 구현체는 가져다 쓰는줄 알았더니 아니네요.)

Source Code에서 사용법과 Method Annotataion 사용법을 보자.

[build.gradle]

	compile springDependencies // Spring 3.2.x
	compile 'org.springframework.data:spring-data-redis:1.3.4.RELEASE'

oscache-2.3.2.jar 가 기존에 포함되어 있길래 재대로 활용해보았다.

하지만 운영서버에서 서버가 버벅되다 죽는것이 확인되었다.

이유를 못 찾는 와중에 WAS 시스템 엔지니어로 부터 OSCache문제라는 통보를 받았다 ㅠ

구글링도 해보았지만 해결책을 쉽게 찾지 못 하였다.

캐쉬 최대 갯수도 늘려보아도 소용이 없던 찰라에 oscache 버전을 최신으로 교체해보았다.

결론은.. 원활하게 운영중이다..

이런. ㅠㅠ

현재 oscache-2.4.1.jar 버전으로 정상 가동중이다.
