PDF
Allen Cao, Niyaz Mohamed, NetApp
목적
Oracle RMAN(Recovery Manager) 백업 툴을 사용하여 Oracle에서 매우 큰 데이터베이스(VLDB)를 복구하는 것은 매우 어려운 작업이 될 수 있습니다. 오류가 발생할 경우 백업 미디어에서 데이터베이스 복원 프로세스를 수행하는 데 시간이 오래 걸릴 수 있으므로 데이터베이스 복구가 지연되고 서비스 수준 계약(SLA)에 상당한 영향을 줄 수 있습니다. 그러나 Oracle은 버전 10g부터 사용자가 DB 서버 호스트에 있는 추가 디스크 스토리지에 Oracle 데이터베이스 데이터 파일의 스테이징된 이미지 복제본을 생성할 수 있는 RMAN 기능을 도입했습니다. 이러한 이미지 복제본은 RMAN을 사용하여 매일 점진적으로 업데이트할 수 있습니다. 장애가 발생할 경우 DBA(데이터베이스 관리자)가 Oracle 데이터베이스를 실패한 미디어에서 이미지 복사본으로 신속하게 전환하여 전체 데이터베이스 미디어 복원이 필요하지 않게 할 수 있습니다. 그 결과, 필요한 데이터베이스 스토리지가 2배로 증가했지만 SLA가 크게 개선되었습니다.
VLDB에 대한 SLA에 관심이 있고 Oracle 데이터베이스를 AWS와 같은 퍼블릭 클라우드로 이전하려는 경우 대기 데이터베이스 이미지 복사본을 스테이징하기 위해 AWS FSx ONTAP와 같은 리소스를 사용하여 유사한 데이터베이스 보호 구조를 설정할 수 있습니다. 이 문서에서는 운영 스토리지 장애 시 신속한 복구를 위해 대기 데이터베이스 복사본을 스테이징하기 위해 AWS FSx ONTAP에서 마운트될 NFS 파일 시스템을 Oracle 데이터베이스 서버에 프로비저닝하고 내보내는 방법을 설명합니다.
또한, NetApp FlexClone을 활용하여 추가 스토리지 투자 없이 동일한 대기 데이터베이스 이미지 복사본을 사용하여 개발/테스트 Oracle 환경을 구축하는 등의 다른 사용 사례에서 동일한 스테이징 NFS 파일 시스템의 복사본을 생성하는 방법도 살펴볼 수 있습니다.
이 솔루션은 다음과 같은 사용 사례를 해결합니다.
-
AWS FSx ONTAP 스토리지의 NFS 마운트 지점에서 RMAN을 통해 Oracle VLDB 이미지 복제 증분 병합이 수행됩니다.
-
장애 발생 시 FSx ONTAP 스토리지의 데이터베이스 이미지 복사본으로 전환하여 Oracle VLDB를 빠르게 복구합니다.
-
클론 FSx ONTAP NFS 파일 시스템 볼륨에 Oracle VLDB 이미지 복제본을 저장하여 다른 활용 사례에서 다른 데이터베이스 인스턴스를 설치하는 데 사용됩니다.

구축 시 고려해야 할 주요 요소
-
* RMAN 증분 병합용 Oracle VLDB 스토리지 레이아웃 * 테스트 및 검증에서 Oracle 증분 백업 및 병합용 NFS 볼륨은 단일 FSx 파일 시스템에서 4Gbps 처리량, 160,000 원시 SSD IOPS 및 192TiB 용량 제한이 있는 할당됩니다. 임계값을 통한 구축의 경우 여러 FSx 파일 시스템을 여러 NFS 마운트 지점과 병렬로 연결하여 더 큰 용량을 제공할 수 있습니다.
-
* RMAN 증분 병합을 사용하여 Oracle 복구 성능. * RMAN 증분 백업 및 병합은 일반적으로 RTO 및 RPO 목표에 따라 사용자 정의 빈도로 실행됩니다. 운영 데이터 스토리지 및/또는 아카이브 로그가 완전히 손실되면 데이터 손실이 발생할 수 있습니다. Oracle 데이터베이스는 FSx 데이터베이스 백업 이미지 복사본에서 사용할 수 있는 마지막 증분 백업까지 복구할 수 있습니다. 데이터 손실을 최소화하기 위해 FSx NFS 마운트 지점에 Oracle 플래시 복구 영역을 설정할 수 있으며 데이터베이스 이미지 복사본과 함께 아카이빙된 로그를 FSx NFS 마운트에 백업할 수 있습니다.
-
* FSx NFS 파일 시스템에서 Oracle VLDB를 실행합니다. * 데이터베이스 백업을 위한 다른 대용량 스토리지와 달리 AWS FSx ONTAP는 높은 수준의 성능과 스토리지 효율성을 제공하는 클라우드 지원 운영 등급 스토리지입니다. Oracle VLDB가 운영 스토리지에서 FSx ONTAP NFS 파일 시스템의 이미지 복제본으로 전환되면 기본 스토리지 장애가 해결되는 동안 데이터베이스 성능을 높은 수준으로 유지할 수 있습니다. 기본 스토리지 장애로 인해 사용자 애플리케이션 환경이 저하되지 않는다는 것을 알면 편리할 수 있습니다.
-
* FlexClone Oracle VLDB 기타 사용 사례에서 NFS 볼륨의 이미지 복사본 * AWS FSx ONTAP FlexClone은 쓰기 가능한 동일한 NFS 데이터 볼륨의 공유 복사본을 제공합니다. 따라서 Oracle 데이터베이스가 전환되더라도 Oracle VLDB 이미지 복제본을 스테이징하는 무결성을 유지하면서 다른 많은 활용 사례에 사용할 수 있습니다. 따라서 VLDB 스토리지 설치 공간이 크게 줄어 스토리지 비용이 크게 절감됩니다. NetApp은 Oracle 성능을 높은 수준으로 유지하기 위해 데이터베이스를 운영 스토리지에서 데이터베이스 이미지 복사본으로 전환하는 경우 FlexClone 활동을 최소화하는 것이 좋습니다.
-
* EC2 컴퓨팅 인스턴스 * 이러한 테스트 및 검증에서는 AWS EC2 T2.xLarge 인스턴스를 Oracle 데이터베이스 컴퓨팅 인스턴스로 사용했습니다. NetApp에서는 데이터베이스 워크로드에 최적화되어 있으므로 운영 구축 시 Oracle용 컴퓨팅 인스턴스로 M5 유형 EC2 인스턴스를 사용할 것을 권장합니다. 실제 워크로드 요구 사항에 따라 vCPU 수와 RAM 양에 따라 EC2 인스턴스를 적절하게 사이징해야 합니다.
-
* FSx 스토리지 HA 클러스터 단일 또는 다중 영역 배포. * 이러한 테스트 및 검증에서는 단일 AWS 가용성 영역에 FSx HA 클러스터를 구축했습니다. 프로덕션 배포를 위해 FSx HA 쌍을 두 가지 가용성 영역에 배포하는 것이 좋습니다. FSx HA 클러스터는 스토리지 레벨 이중화를 제공하기 위해 액티브-패시브 파일 시스템 쌍으로 미러링되는 HA 쌍으로 프로비저닝됩니다. 다중 영역 구축을 통해 단일 AWS 영역에서 장애가 발생할 경우 고가용성을 더욱 강화할 수 있습니다.
-
* FSx 스토리지 클러스터 크기 조정 * ONTAP 스토리지 파일 시스템용 Amazon FSx는 최대 160,000개의 원시 SSD IOPS, 최대 4Gbps 처리량 및 최대 192TiB 용량을 제공합니다. 그러나 구현 시 실제 요구 사항에 따라 프로비저닝된 IOPS, 처리량 및 스토리지 제한(최소 1,024GiB)을 기준으로 클러스터 크기를 조정할 수 있습니다. 애플리케이션 가용성에 영향을 주지 않고 용량을 즉각적으로 동적으로 조정할 수 있습니다.
-
* dNFS 구성. * dNFS는 Oracle 커널에 내장되어 있으며 Oracle을 NFS 스토리지에 구축할 때 Oracle 데이터베이스 성능을 크게 향상시키는 것으로 알려져 있습니다. dNFS는 Oracle 바이너리로 패키징되지만 기본적으로 활성화되어 있지 않습니다. NFS 기반 Oracle 데이터베이스 구축 시 이 기능을 설정해야 합니다. VLDB를 위한 여러 FSx 파일 시스템 배포의 경우 다른 FSx NFS 파일 시스템에 대한 dNFS 다중 경로를 올바르게 구성해야 합니다.

FSx에서 이미지 복사본에 대한 Oracle RMAN 증분 병합을 설정합니다
Details
RMAN 증분 병합은 증분 백업/병합 간격마다 스테이징 데이터베이스 데이터 파일 이미지 복제본을 지속적으로 업데이트합니다. 데이터베이스 백업의 이미지 복사본은 증분 백업/병합을 실행하는 빈도만큼 최신 상태가 됩니다. 따라서 RMAN 증분 백업 및 병합의 빈도를 결정할 때 데이터베이스 성능, RTO 및 RPO 목표를 고려해야 합니다.

sqlplus를 통해 Oracle 데이터베이스에 로그인하고, 블록 변경 추적을 설정하여 증분 백업을 가속화하고, Oracle 플래시 복구 영역을 현재 운영 스토리지에 있는 경우 FSxN 마운트로 변경합니다. 따라서 RMAN 기본 제어 파일/spfile 자동 백업 및 아카이빙된 로그를 복구를 위해 FSxN NFS 마운트에 백업할 수 있습니다.
sqlplus / as sysdbasqlplus 프롬프트에서 다음 명령을 실행합니다.

RMAN 백업 및 증분 병합 스크립트를 생성합니다. 이 스크립트는 병렬 RMAN 백업 및 병합을 위해 여러 채널을 할당합니다. 첫 번째 실행에서는 초기 전체 기준선 이미지 복사본이 생성됩니다. 전체 실행에서 먼저 보존 기간 외부에 있는 폐기된 백업을 정리하여 스테이징 영역을 깨끗하게 유지합니다. 그런 다음 병합 및 백업 전에 현재 로그 파일을 전환합니다. 증분 백업은 병합 후에 데이터베이스 이미지 복사본이 현재 데이터베이스 상태를 하나의 백업/병합 주기로 후행 하도록 합니다. 병합 및 백업 순서를 반대로 하면 사용자가 원하는 대로 신속하게 복구할 수 있습니다. RMAN 스크립트는 기본 DB 서버의 crontab에서 실행할 간단한 셸 스크립트로 통합할 수 있습니다. RMAN 설정에서 제어 파일 자동 백업이 켜져 있는지 확인합니다.

이것으로 Oracle 데이터베이스 대기 이미지 복사 백업 및 병합의 설치가 완료되었습니다.
빠른 복구를 위해 Oracle DB를 이미지 복제본으로 전환합니다
Details
데이터 손실 또는 손상과 같은 운영 스토리지 문제로 인해 장애가 발생할 경우 데이터베이스를 FSx ONTAP NFS 마운트의 이미지 복제본으로 신속하게 전환하며 데이터베이스 복구 없이 현재 상태로 복구할 수 있습니다. 미디어 복원을 제거하면 VLDB의 데이터베이스 복구 속도가 엄청나게 빨라집니다. 이 활용 사례에서는 데이터베이스 호스트 인스턴스가 온전하고 데이터베이스 제어 파일, 아카이브된 로그 및 현재 로그를 모두 복구에 사용할 수 있다고 가정합니다.

Oracle 사용자로 EC2 DB 서버 호스트에 로그인하고 테스트 테이블을 생성한 후 전환합니다.

FSx ONTAP는 뛰어난 성능을 제공하는 이중화된 운영 등급 스토리지이므로 FSx NFS 마운트에서 Oracle 데이터베이스를 장기간 동안 성능 저하 없이 실행할 수 있습니다. 운영 스토리지 문제가 해결되면 가동 중지 시간을 최소화하면서 증분 백업 병합 프로세스를 반대로 수행하여 다시 되돌릴 수 있습니다.
이미지 복사본에서 다른 EC2 DB 인스턴스 호스트로 Oracle DB 복구
Details
운영 스토리지와 EC2 DB 인스턴스 호스트가 모두 손실되는 경우 원래 서버에서 복구를 수행할 수 없습니다. 하지만 이중화 FSxN NFS 파일 시스템에 여전히 Oracle 데이터베이스 백업 이미지 복제본이 있습니다. 동일한 EC2 DB 인스턴스를 다시 빠르게 프로비저닝하고 NFS를 통해 VLDB의 이미지 복사본을 새 EC2 DB 호스트에 쉽게 마운트하여 복구를 실행할 수 있습니다. 이 섹션에서는 이러한 작업을 위한 단계별 절차를 시연합니다.

운영 EC2 DB 인스턴스 호스트를 종료하여 스토리지 및 DB 서버 호스트의 총 장애를 시뮬레이션합니다.

AWS EC2 콘솔을 통해 OS와 버전이 동일한 새 EC2 DB 인스턴스 호스트 ora_02 를 사용합니다. 운영 EC2 DB 서버 호스트와 동일한 패치를 사용하여 운영 체제 커널 을 구성하고, Oracle은 RPM을 사전 설치하고, 호스트에 스왑 공간을 추가합니다. 소프트웨어만 제공하는 운영 EC2 DB 서버 호스트와 동일한 버전의 Oracle 패치를 설치합니다. 아래 링크에서 제공되는 NetApp 자동화 툴킷을 사용하여 이러한 작업을 자동화할 수 있습니다.
-
oratab, oraInst.loc 및 Oracle user.bash_profile과 같은 Oracle 환경을 운영 EC2 DB 인스턴스 호스트 ora_01에 맞게 구성합니다. 이러한 파일을 FSxN NFS 마운트 지점에 백업하는 것이 좋습니다.

FSxN NFS 마운트의 Oracle 데이터베이스 백업 이미지 복사본은 이중화, 고가용성 및 고성능을 위해 AWS 가용성 영역을 확장하는 FSx 클러스터에 저장됩니다. 네트워킹에 연결할 수 있는 한 NFS 파일 시스템을 새 서버에 쉽게 마운트할 수 있습니다. 다음 절차에서는 복구를 위해 Oracle VLDB 백업의 이미지 복제본을 새로 프로장된 EC2 DB 인스턴스 호스트에 마운트합니다.

sudo mkdir /nfsfsxnEC2-USER로 Oracle VLDB 백업 이미지 복사본을 저장한 NFS 볼륨을 마운트합니다.

기타 복구 후 작업
Add FSxN NFS mount to fstab so that the NFS file system will be mounted when EC2 instance host rebooted. As EC2 user, vi /etc/fstab and add following entry: 172.30.15.19:/ora_01_copy /nfsfsxn nfs rw,bg,hard,vers=3,proto=tcp,timeo=600,rsize=262144,wsize=262144,nointr 0 0 Update the Oracle init file from primary databse init file backup that is restored to /tmp/archive and create spfile as needed.
이로써 FSxN NFS 파일 시스템의 백업 이미지 복제본에서 새로운 EC2 DB 인스턴스 호스트로 Oracle VLDB 데이터베이스 복구가 완료됩니다.
다른 활용 사례를 위해 Oracle 대기 이미지 복제본을 복제합니다

Oracle VLDB 이미지 복제본을 스테이징하기 위해 AWS FSx ONTAP를 사용하는 또 다른 이점은 FlexCluned가 최소한의 추가 스토리지 투자로 다른 많은 용도로 사용할 수 있다는 것입니다. 다음 활용 사례에서는 FSx ONTAP에서 DEV, UAT 등과 같은 다른 Oracle 활용 사례에 대해 스테이징 NFS 볼륨을 스냅샷 및 복제하는 방법을 시연합니다

이제 복구 프로세스는 기본 운영 인스턴스와 일치하도록 장애 설정 Oracle 환경(oratab, $oracle_home, $oracle_sid)이 설정된 후 새로운 EC2 DB 인스턴스에 대한 복구의 이전 사용 사례와 유사합니다. FSx NFS 마운트의 플래시 복구 디렉토리를 가리키는 db_recovery_file_dest_size 및 db_recovery_file_dest를 포함한 초기화 파일을 생성합니다. 그런 다음 복구를 실행하기 위해 RMAN을 사용합니다. 다음은 명령 단계와 출력입니다.
