[DB2 V.11.1] Deinstall 하기

테스트 하던 DB2의 라이센스 기간이 지나서 start가 되지 않는 상황이 발생.

삭제하고 재설치하는게 빠를거 같아서 삭제할때 썼던 스크립트를 정리하는 글을 작성해봅니다.

 

삭제는 세가지를 해야합니다.

1.인스턴스

2.DB엔진

3.유저

 

순서도 인스턴스 -> DB엔진 -> 유저 순으로 삭제하면 됩니다.

 

1.인스턴스 삭제

$./db2/db2test/bin/db2ilist
db2test
db2lds

--첫번째 인스턴스 삭제
$ ./db2/db2test/instance/db2idrop db2test
