안녕하세요
현재 db 버젼은 DB2 v9.1.0.4 를 사용하고 있으며 SAP on DB2 입니다.
지금 현상은 HWM가 너무 높아져서 DB2DART를 사용하여 해당 오브 젝트들을 모두 reorg 해주었는데
HWM 가내려가지 않아 DB2DART를 사용하여 다시한번 내리니 아래와 같은 로그가 발생 되었습니다.
사용 스크립트 : db2dart BID /LHWM /TSI 32 /NP 0

NOTES: All highwater mark values and/or object sizes listed below are given in extents and not pages (unless explicitly stated).
The object ID and object type are shown for each extent listed.
Extents marked with an asterisk (*) hold the first page of an object and these extents can only be moved by dropping and recreating that object.
Extents marked as belonging to objects with ID equal to 65534 or 65535 are SMP extents or object table extents and they are not movable.
After following a step and before continuing on to the next one, disconnect and reconnect to the database.

위와 같은 메세지가 나와 아래의 명령어를 사용하여 HWM를 내려보았지만
사용스크립트 : db2dart bid /tsi 32 /np 0 /rhwm
또한 HWM도 내려가지 않았으며 백업 펜딩도 걸리지 않았습니다.
위스크립트의 로그는 아래와 같습니다.

위와 같은 로그만 생기고 HWM가 내려가지 않습니다.
HWM를 내릴수있는 방법을 알려주셨으면 감사하겠습니다.
감사합니다.
