在Oracle 12c RAC环境下进行了内联网络失败的时候RAC如何表现得实验，发现Oracle 12c RAC和11g/10g RAC有所区别，如果内联网络失败，在11g/10g RAC中将会把问题节点从集群中驱逐，该节点而且会尝试自动重启以尝试恢复。但Oracle 12c RAC则只是把问题节点从集
在Oracle 12c RAC环境下进行了内联网络失败的时候RAC如何表现得实验，发现Oracle 12c RAC和11g/10g RAC有所区别，如果内联网络失败，在11g/10g RAC中将会把问题节点从集群中驱逐，该节点而且会尝试自动重启以尝试恢复。但Oracle 12c RAC则只是把问题节点从集群中驱逐，并没有重启该节点。下面看实验。

Oracle 데이터베이스 로그는 얼마나 오래 보관됩니까?
May 10, 2024 am 03:27 AM
Oracle 데이터베이스 로그의 보존 기간은 다음을 포함한 로그 유형 및 구성에 따라 다릅니다. 재실행 로그: "LOG_ARCHIVE_DEST" 매개변수로 구성된 최대 크기에 의해 결정됩니다. 보관된 리두 로그: "DB_RECOVERY_FILE_DEST_SIZE" 매개변수로 구성된 최대 크기에 따라 결정됩니다. 온라인 리두 로그: 보관되지 않고 데이터베이스를 다시 시작하면 손실되며 보존 기간은 인스턴스 실행 시간과 일치합니다. 감사 로그: "AUDIT_TRAIL" 매개변수로 구성되며 기본적으로 30일 동안 보관됩니다.
Oracle 데이터베이스 시작 단계의 순서는 다음과 같습니다.
May 10, 2024 am 01:48 AM
Oracle 데이터베이스 시작 순서는 다음과 같습니다. 1. 전제 조건을 확인합니다. 3. 데이터베이스 인스턴스를 시작합니다. 5. 데이터베이스에 연결합니다. . 서비스를 활성화합니다(필요한 경우). 8. 연결을 테스트합니다.
오라클에는 얼마나 많은 메모리가 필요합니까?
May 10, 2024 am 04:12 AM
Oracle에 필요한 메모리 양은 데이터베이스 크기, 활동 수준 및 필요한 성능 수준(데이터 버퍼 저장, 인덱스 버퍼, SQL 문 실행 및 데이터 사전 캐시 관리에 필요)에 따라 다릅니다. 정확한 양은 데이터베이스 크기, 활동 수준 및 필요한 성능 수준에 따라 달라집니다. 모범 사례에는 적절한 SGA 크기 설정, SGA 구성 요소 크기 조정, AMM 사용 및 메모리 사용량 모니터링이 포함됩니다.
