[증상]
Oracle RAC ocssd.bin Process를 Kill 하는 경우 전체 Node 또는 일부 Node가 Reboot 발생
[환경]
IBM AIX + Oracle RAC 19c + Veritas CFS
[원인]
Oracle CSS misscount 값이 30, disktimeout 597로 Setting 되어 있음
[해결책]
Oracle CSS misscount 값을 600으로 변경
[기타사항]
Oracle RAC 19c 구성 후 Veritas Relink 단계에서 Oracle CRS가 기동 되어 있어야 함.
만약, Oracle CRS가 중자 상태에서 Veritas Relink를 수행 하면 Oracle CSS misscount 값을 600으로 변경 하라는 안내 메시지가 나옴.
[참고문서]
Oracle Clusterware에서 CSS Timeout 계산 (Doc ID 2158867.1)
[환경]
IBM AIX 7.2 + Oracle CRS/DB 11.2.0.4 + 2-Node RAC + ASM + PSU 11.2.0.4.201020
[증 상]
PSU 11.2.0.4.201020 적용 마지막 단계인 rootcrs.pl -patch 실행 하면 약 10분~15분간 대기 하다 crsconfig_lib.pm line 11821 발생 하며 실패
Oracle ASM Instance 기동 되지 않음
[원 인]
BUG 32123313 - SMR FILE KEEPS GETTING CORRUPTED AFTER APPLYING OCT 2020 DBPSU IN AIX7
Bug 32109594 - ASM IS UNABLE TO START WITH SMR CORRUPTED ERROR POST OCT 2020 PSU APPLY
[해결방법]
Patch 32109594 적용 전 rootcrs.pl -unlock
Patch 32109594를 $GRID_HOME과 $ORACLE_DB_HOME모두 적용
Patch 32109594 적용 후 rootcrs.pl -patch
[참고문서]
AIX:11.2.0.4 :ASM&DB Instance Not Starting Up Due to SMR Corrupt After OCT 2020 PSU (문서 ID 2732507.1)
Oracle MOS를 찾아 보니 IBM AIX 7.2에 PSU 11.2.0.4.201020 이상을 적용하면 발생 하는 것 같다.
