PASSWORD_ROLLOVER_TIME 2
2022.12.06 - [Oracle/Oh Oracle ] - PROFILE 중 PASSWORD_ROLLOVER_TIME 추가됨 ( 19.12 부터 지원 ) 2
PASSWORD_ROLLOVER_TIME : 쉽게 말해서, PASSWORD 변경 후, 한시적으로 이전 비번/현재 비번으로 로그인 가능하도록 지원 해주는 기능으로 19.12 부터 지원됨
보안 강화로, 주기적으로 비번 변경 시, 변경 후, Application(WAS) 재기동에 여유를 갖을 수 있다.

PASSWORD_ROLLOVER_TIME 을 할당 혹은 활성화 후에 비번 변경 시만, ROLLOVER가 적용 된다.
EX) PASSWORD_ROLLOVER_TIME 할당/활성화 -> 비번 변경 -> 전/후 비번으로 로그인 성공
EX) 비번 변경 -> PASSWORD_ROLLOVER_TIME 할당/활성화 -> 후(최근) 비번으로만 로그인 성공
Gradual Database Password Rollover Time (PASSWORD_ROLLOVER_TIME) in Oracle Database 19c and 21c
From Oracle 21c onward we can define a password rollover time, which allows us to connect using both the old and the new passwords during the gradual rollover time period. This feature was backported to Oracle 19c in the 19.12 release update.
