OS 환경 : Oracle Linux 7.6 (64bit)
DB 환경 : Oracle Database 19.3.0.0
방법 : 오라클 19c ordered_predicates 힌트 사용 확인(XPLAN, 10053 비교)
오라클에는 ordered_predicates 라는 힌트가 존재함
이 힌트는 쿼리의 where 절에 포함된 조건들이 지정된 순서대로 평가되도록 강제함
일반적으로 오라클 옵티마이저는 조건들을 최적의 순서로 평가하여 쿼리 성능을 최적화하려고 하는데 특정 상황에서는 사용자가 명시한 순서대로 조건을 평가하는 것이 더 효율적일 수 있음
이 경우 ordered_predicates 힌트를 사용하면 옵티마이저에게 조건 평가 순서를 강제하도록 명령할 수 있음
본문에서는 이 힌트가 19c에서도 제대로 동작하는지 여부를 xplan 과 10053 트레이스로 확인해봄

힌트 사용시 : CUSTOMER_ID, CITY, AGE, AMOUNT 순서로 평가됨
결론 :
ORDERED_PREDICATES 힌트가 19c에서도 잘 동작함, 하지만 xplan 에서는 Hint Report에서 사용여부만 확인 가능하고 세부적인 확인은 불가능했음
하지만 10053 트레이스에서는 조건절 평가 순서를 변경하는데 기여하는것을 확인할 수 있었음
추가로 10053은 트레이스가 길어서 모두 보기는 힘들지만 최소 아래 포인트 정도만이라도 확인할수 있으면 좋음
- 쿼리 블록 등록 정보 : 옵티마이저가 각 쿼리 블록을 어떻게 인식하고 처리하는지 확인함
예시 : Registered qb: SEL$1 0x... (PARSER)
- 변환 후 쿼리: 옵티마이저가 쿼리를 변환한 후의 상태를 보여줌
예시 : Final query after transformations:
- Predicate Information : 실행 계획의 각 단계에서 조건절이 어떻게 사용되는지를 설명함(필터 및 엑세스, 조인 조건으로 사용되는지 등)
예시 : Predicate Information (identified by operation id):
- 조건 평가 순서 (finally): 최종적으로 조건이 어떤 순서로 평가될지를 보여줌
예시: finally: "C"."CUSTOMER_ID"="O"."CUSTOMER_ID" AND "C"."CITY"='New York' AND "C"."AGE">25 AND "O"."AMOUNT">100
