•
startdbpg에 접속해 아래 SQL들을 순차적으로 실행해 튜닝 테스트용 테이블을 생성합니다.
•
반드시 DBeaver에 Autocommit 상태로 접속해서 작업을 진행합니다.
◦
DBeaver 상단 메뉴 > 데이터베이스 > 트랜잭션 모드 > Auto-Commit
•
번거럽더라도, 가능하면 SQL을 하나씩 순차적으로 실행하는 것을 권장합니다.
◦
특히 중간에 프로시저 생성 부분은 별도 창에서 별도로 실행하는 것을 권장합니다.
•
일부 SQL은 오래 걸립니다. 오래 걸리는 중간에 동일 SQL 창에서 다른 SQL을 실행하면 DBeaver 내부적으로 행이 걸리는 상태가 종종 발생합니다.
◦
차분히 기다리면서 한 문장씩 순차적으로 실행하세요.
◦
제 개인 환경에서는 아래 스크립트 전부 실행하는 30분 정도 걸렸습니다.
