2번 서버로 인스턴스 이동
[oracle@seha admin]$ srvctl relocate database -d seha -n seha2 -w 1 -v

[oracle@seha admin]$ srvctl   relocate   database -h

RAC One Node 데이터베이스의 온라인 재배치를 시작합니다.

사용법: srvctl relocate database -db <db_unique_name> {[-node <target>] [-timeout <timeout>] [-stopoption <stop_option>] | -abort [-revert]} [-drain_timeout <timeout>] [-verbose]
    -db <db_unique_name>           재배치할 데이터베이스의 고유 이름
    -node <target>                 데이터베이스를 재배치할 대상 노드
    -timeout <timeout>             온라인 재배치 시간 초과(분)
    -abort                         실패한 온라인 재배치 중단
    -revert                        관리자 관리 RAC One Node 데이터베이스의 후보 서버 목록에서 실패한 온라인 재배치 요청의 대상 노드 제거
    -stopoption <stop_option>      인스턴스 실행을 위한 기본 종료 옵션 무효화(NORMAL만 허용됨)
    -drain_timeout <drain_timeout> 초 단위로 지정된 서비스 비우기 시간 초과입니다.
    -verbose                       상세 정보 출력

옵션 설명
출처:https://hoing.io/archives/5280#relocate
-w 옵션을 기술 하지 않는다면 online relocation timeout : 30  이 적용 됩니다.
단위 는 분 이며 이 시간은 세션을 종료 하고 , 인스턴스를 migrate , 트랜잭션을 OPEN 하는 시간을 의미 합니다.

시간 안에  트랜젝션이 종료 되지 않는다면, shutdown abort 과 같은 일환으로 트랜젝션은 취소 가  되며, 세션은 사라지게 됩니다.

이런 시간에 대한 제한에 대해서 default 30분이 아닌 다른 시간으로 제한을 두고자 할 때 -w 옵션을 사용하게 됩니다.

보통의 경우 테스트 문서나 외국 문서들의 대부분이 -w 1 을 주며 시간의 범위는 1~720 분 까지 입니다.
