[COH] IBM AIX - The socket name is not available on this system

- ISSUE : IBM AIX에서 Multicast 주소로 구성된 Coherence Cluster Server 기동시 실패 에러 발생하는 현상

- CAUSE : Java는 OS에서 IPv4와 IPv6 모두 사용할 경우 IPv6를 우선적으로 사용한다. 

              그렇기 때문에, Coherence Cluster Multicast 설정시 IPv4 형식으로 설정했기 때문에 Socket Exception

              이 발생한 것이다.

- Solution : Coherence 기동 스크립트에 IPv4를 우선적으로 사용할 수 있도록 아래 자바 옵션을 추가한다.

COHERENCE_OPTS="${COHERENCE_OPTS} -Djava.net.preferIPv4Stack=true"
