기여자
변경 제안
PDF
Allen Cao, Niyaz Mohamed, NetApp
이 솔루션은 FSx ONTAP 에 NFS 마운트를 사용하여 AWS EC2 컴퓨팅 인스턴스에 배포된 Oracle VLDB의 빠른 복구 및 복제에 대한 개요와 세부 정보를 제공하고, RMAN을 통해 지속적으로 증분 병합할 대기 데이터 파일 복사본을 준비합니다.
목적
Oracle Recovery Manager(RMAN) 백업 도구를 사용하여 Oracle에서 매우 큰 데이터베이스(VLDB)를 복구하는 것은 매우 어려운 작업이 될 수 있습니다. 장애 발생 시 백업 미디어에서 데이터베이스를 복원하는 과정은 시간이 많이 걸릴 수 있으며, 데이터베이스 복구가 지연되고 잠재적으로 서비스 수준 계약(SLA)에 상당한 영향을 미칠 수 있습니다. 그러나 Oracle은 10g 버전부터 사용자가 DB 서버 호스트에 있는 추가 디스크 스토리지에 Oracle 데이터베이스 데이터 파일의 단계적 이미지 복사본을 생성할 수 있는 RMAN 기능을 도입했습니다. 이러한 이미지 복사본은 RMAN을 사용하여 매일 증분적으로 업데이트할 수 있습니다. 장애가 발생한 경우, 데이터베이스 관리자(DBA)는 장애가 발생한 미디어에서 이미지 복사본으로 Oracle 데이터베이스를 신속하게 전환할 수 있으므로 데이터베이스 미디어를 완전히 복원할 필요가 없습니다. 결과적으로 SLA는 크게 향상되었지만, 필요한 데이터베이스 저장 용량은 두 배로 늘어나게 됩니다.
VLDB에 대한 SLA를 원하고 Oracle 데이터베이스를 AWS와 같은 퍼블릭 클라우드로 옮기는 것을 고려하고 있다면 AWS FSx ONTAP 과 같은 리소스를 사용하여 스탠바이 데이터베이스 이미지 복사본을 스테이징하는 유사한 데이터베이스 보호 구조를 설정할 수 있습니다. 이 문서에서는 AWS FSx ONTAP 에서 NFS 파일 시스템을 프로비저닝하고 내보내 Oracle 데이터베이스 서버에 마운트하여 기본 스토리지 장애 발생 시 신속한 복구를 위해 대기 데이터베이스 복사본을 준비하는 방법을 보여줍니다.
더 나아가, NetApp FlexClone 활용하여 추가 스토리지 투자 없이 동일한 대기 데이터베이스 이미지 복사본으로 개발/테스트 Oracle 환경을 구축하는 등의 다른 사용 사례를 위해 동일한 스테이징 NFS 파일 시스템의 복사본을 만드는 방법도 보여드립니다.
이 솔루션은 다음과 같은 사용 사례를 해결합니다.
-
AWS FSx ONTAP 스토리지의 NFS 마운트 지점에서 RMAN을 통해 Oracle VLDB 이미지 복사 증분 병합.
-
장애 발생 시 FSx ONTAP 스토리지에 있는 데이터베이스 이미지 복사본으로 전환하여 Oracle VLDB를 빠르게 복구합니다.
-
다른 사용 사례를 위해 또 다른 데이터베이스 인스턴스를 구축하는 데 사용할 Oracle VLDB 이미지 복사본을 저장하는 FSx ONTAP NFS 파일 시스템 볼륨을 복제합니다.

배포 고려사항의 핵심 요소
-
RMAN 증분 병합을 위한 Oracle VLDB 저장 레이아웃. 테스트와 검증에서 Oracle 증분 백업 및 병합을 위한 NFS 볼륨은 처리량이 4GBps, 원시 SSD IOPS가 160,000이고 용량 제한이 192TiB인 단일 FSx 파일 시스템에서 할당되었습니다. 임계값을 초과하여 배포하는 경우, 여러 FSx 파일 시스템을 여러 NFS 마운트 지점과 병렬로 연결하여 더 높은 용량을 제공할 수 있습니다.
-
RMAN 증분 병합을 사용한 Oracle 복구성. RMAN 증분 백업 및 병합은 일반적으로 RTO 및 RPO 목표에 따라 사용자가 정의한 빈도로 실행됩니다. 1차 데이터 저장소 및/또는 보관된 로그가 완전히 손실되면 데이터 손실이 발생할 수 있습니다. Oracle 데이터베이스는 FSx 데이터베이스 백업 이미지 복사본에서 사용 가능한 마지막 증분 백업까지 복구할 수 있습니다. 데이터 손실을 최소화하기 위해 Oracle 플래시 복구 영역을 FSx NFS 마운트 지점에 설정하고 보관된 로그를 데이터베이스 이미지 복사본과 함께 FSx NFS 마운트에 백업할 수 있습니다.
-
FSx NFS 파일 시스템에서 Oracle VLDB 실행. 데이터베이스 백업을 위한 다른 대용량 스토리지와 달리 AWS FSx ONTAP 높은 수준의 성능과 스토리지 효율성을 제공하는 클라우드 지원 프로덕션 등급 스토리지입니다. Oracle VLDB가 기본 저장소에서 FSx ONTAP NFS 파일 시스템의 이미지 복사본으로 전환되면 기본 저장소 오류가 해결되는 동안에도 데이터베이스 성능을 높은 수준으로 유지할 수 있습니다. 기본 저장소 오류로 인해 사용자 애플리케이션 경험이 저하되지 않는다는 사실을 알면 안심할 수 있습니다.
-
* 다른 사용 사례를 위한 NFS 볼륨의 FlexClone Oracle VLDB 이미지 복사본.* AWS FSx ONTAP FlexClone 쓰기 가능한 동일한 NFS 데이터 볼륨의 공유 복사본을 제공합니다. 따라서 Oracle 데이터베이스가 전환될 때에도 Oracle VLDB 이미지 복사본의 스테이징 무결성을 유지하면서 다른 많은 사용 사례에 사용할 수 있습니다. 이를 통해 VLDB 스토리지 공간을 대폭 줄여 스토리지 비용을 엄청나게 절감할 수 있습니다. NetApp Oracle 성능을 높은 수준으로 유지하기 위해 기본 스토리지에서 데이터베이스 이미지 복사본으로 데이터베이스를 전환하는 경우 FlexClone 활동을 최소화할 것을 권장합니다.
-
EC2 컴퓨팅 인스턴스. 이러한 테스트와 검증에서는 Oracle 데이터베이스 컴퓨팅 인스턴스로 AWS EC2 t2.xlarge 인스턴스를 사용했습니다. NetApp 프로덕션 배포 시 Oracle의 컴퓨팅 인스턴스로 M5 유형 EC2 인스턴스를 사용할 것을 권장합니다. 이는 데이터베이스 작업 부하에 최적화되어 있기 때문입니다. 실제 작업 부하 요구 사항에 따라 vCPU 수와 RAM 양에 맞게 EC2 인스턴스 크기를 적절히 조정해야 합니다.
-
FSx 스토리지 HA 클러스터 단일 또는 다중 영역 배포. 이러한 테스트와 검증을 통해 단일 AWS 가용성 영역에 FSx HA 클러스터를 배포했습니다. 프로덕션 배포의 경우 NetApp 두 개의 서로 다른 가용성 영역에 FSx HA 쌍을 배포할 것을 권장합니다. FSx HA 클러스터는 항상 스토리지 수준 중복성을 제공하기 위해 액티브-패시브 파일 시스템 쌍에 동기화 미러링된 HA 쌍으로 프로비저닝됩니다. 다중 영역 배포는 단일 AWS 영역에서 장애가 발생할 경우 고가용성을 더욱 향상시킵니다.
-
FSx 스토리지 클러스터 크기 조정. Amazon FSx ONTAP 스토리지 파일 시스템은 최대 160,000 원시 SSD IOPS, 최대 4GBps 처리량, 최대 192TiB 용량을 제공합니다. 그러나 배포 시점의 실제 요구 사항에 따라 프로비저닝된 IOPS, 처리량 및 저장 용량 한도(최소 1,024GiB)를 기준으로 클러스터 크기를 조정할 수 있습니다. 애플리케이션 가용성에 영향을 주지 않고 용량을 즉시 동적으로 조정할 수 있습니다.
-
dNFS 구성. dNFS는 Oracle 커널에 내장되어 있으며 Oracle을 NFS 스토리지에 배포할 때 Oracle 데이터베이스 성능을 획기적으로 높이는 것으로 알려져 있습니다. dNFS는 Oracle 바이너리에 패키징되어 있지만 기본적으로 켜져 있지 않습니다. NFS에 Oracle 데이터베이스를 배포하는 경우 이 기능을 켜야 합니다. VLDB에 여러 FSx 파일 시스템을 배포하는 경우, 다양한 FSx NFS 파일 시스템에 대한 dNFS 다중 경로를 적절히 구성해야 합니다.

FSx에서 Oracle RMAN 증분 병합을 이미지 복사로 설정
Details
RMAN 증분 병합은 모든 증분 백업/병합 간격마다 스테이징 데이터베이스 데이터 파일 이미지 복사본을 지속적으로 업데이트합니다. 데이터베이스 백업의 이미지 사본은 증분 백업/병합을 실행하는 빈도에 따라 최신 상태로 유지됩니다. 따라서 RMAN 증분 백업 및 병합 빈도를 결정할 때는 데이터베이스 성능, RTO 및 RPO 목표를 고려하세요.

sqlplus를 통해 Oracle 데이터베이스에 로그인하고, 더 빠른 증분 백업을 위해 블록 변경 추적을 활성화하고, 현재 기본 스토리지에 있는 경우 Oracle 플래시 복구 영역을 FSx ONTAP 마운트로 변경합니다. 이를 통해 RMAN 기본 제어 파일/spfile 자동 백업 및 보관된 로그를 복구를 위해 FSx ONTAP NFS 마운트에 백업할 수 있습니다.
sqlplus / as sysdbasqlplus 프롬프트에서 다음 명령을 실행합니다.

RMAN 백업 및 증분 병합 스크립트를 만듭니다. 스크립트는 병렬 RMAN 백업 및 병합을 위해 여러 채널을 할당합니다. 첫 번째 실행에서는 초기 전체 기준선 이미지 복사본이 생성됩니다. 전체 실행에서는 먼저 보존 기간이 지난 오래된 백업을 제거하여 스테이징 영역을 깨끗하게 유지합니다. 그런 다음 병합 및 백업 전에 현재 로그 파일을 전환합니다. 증분 백업은 병합 이후에 이루어지므로 데이터베이스 이미지 복사본은 현재 데이터베이스 상태보다 백업/병합 주기 하나 뒤처집니다. 사용자의 선호에 따라 병합 및 백업 순서를 바꾸어 더 빠르게 복구할 수 있습니다. RMAN 스크립트는 기본 DB 서버의 crontab에서 실행되는 간단한 셸 스크립트로 통합될 수 있습니다. RMAN 설정에서 제어 파일 자동 백업이 켜져 있는지 확인하세요.

이것으로 Oracle 데이터베이스 대기 이미지 복사본 백업 및 병합 설정이 완료되었습니다.
빠른 복구를 위해 Oracle DB를 이미지 복사본으로 전환
Details
데이터 손실이나 손상 등 기본 저장소 문제로 인한 장애가 발생하는 경우, 데이터베이스는 FSx ONTAP NFS 마운트의 이미지 복사본으로 빠르게 전환되고 데이터베이스 복원 없이도 현재 상태로 복구될 수 있습니다. 미디어 복원을 제거하면 VLDB의 데이터베이스 복구 속도가 엄청나게 빨라집니다. 이 사용 사례에서는 데이터베이스 호스트 인스턴스가 손상되지 않았고 데이터베이스 제어 파일, 보관된 로그 및 현재 로그를 모두 복구에 사용할 수 있다고 가정합니다.
-
EC2 DB 서버 호스트에 Oracle 사용자로 로그인하고 전환하기 전에 테스트 테이블을 만듭니다.

FSx ONTAP 고성능을 제공하는 중복 프로덕션 등급 스토리지이므로 성능 저하 없이 장기간 FSx NFS 마운트에서 Oracle 데이터베이스를 실행할 수 있습니다. 기본 저장소 문제가 해결되면 증분 백업 병합 프로세스를 역으로 수행하여 최소한의 가동 중지 시간으로 원래 상태로 돌아갈 수 있습니다.
이미지 복사본에서 다른 EC2 DB 인스턴스 호스트로 Oracle DB 복구
Details
기본 스토리지와 EC2 DB 인스턴스 호스트가 모두 손실되는 장애가 발생하면 원래 서버에서 복구를 수행할 수 없습니다. 다행히도 중복된 FSx ONTAP NFS 파일 시스템에 Oracle 데이터베이스 백업 이미지 사본이 남아 있습니다. 빠르게 동일한 EC2 DB 인스턴스를 프로비저닝하고 NFS를 통해 VLDB의 이미지 복사본을 새 EC2 DB 호스트에 쉽게 마운트하여 복구를 실행할 수 있습니다. 이 섹션에서는 이를 위한 단계별 절차를 보여드리겠습니다.

AWS EC2 콘솔을 통해 동일한 OS 및 버전을 사용하는 새로운 EC2 DB 인스턴스 호스트 ora_02를 보호합니다. 기본 EC2 DB 서버 호스트와 동일한 패치로 OS 커널을 구성하고, Oracle RPM을 사전 설치하고, 호스트에 스왑 공간도 추가합니다. 소프트웨어 전용 옵션으로 기본 EC2 DB 서버 호스트와 동일한 버전의 Oracle과 패치를 설치합니다. 이러한 작업은 아래 링크에서 제공되는 NetApp 자동화 툴킷을 사용하여 자동화할 수 있습니다.

oratab, oraInst.loc, oracle 사용자 .bash_profile 등 기본 EC2 DB 인스턴스 호스트 ora_01과 유사하게 oracle 환경을 구성합니다. 해당 파일을 FSx ONTAP NFS 마운트 지점에 백업하는 것이 좋습니다.

FSx ONTAP NFS 마운트의 Oracle 데이터베이스 백업 이미지 복사본은 중복성, 높은 가용성 및 고성능을 위해 AWS 가용성 영역에 걸쳐 있는 FSx 클러스터에 저장됩니다. NFS 파일 시스템은 네트워크에 접속 가능한 한 새로운 서버에 쉽게 마운트할 수 있습니다. 다음 절차에서는 복구를 위해 Oracle VLDB 백업의 이미지 복사본을 새로 제공된 EC2 DB 인스턴스 호스트에 마운트합니다.
ec2-user로 마운트 지점을 생성합니다.
sudo mkdir /nfsfsxnec2-user로 Oracle VLDB 백업 이미지 복사본이 저장된 NFS 볼륨을 마운트합니다.

더 빠른 복구를 위해 recovery_parallelism 매개변수로 병렬 세션을 활성화하거나 데이터베이스 복구를 위한 복구 명령에서 병렬 정도를 지정하세요. RECOVER DATABASE PARALLEL (DEGREE d INSTANCES DEFAULT);. 일반적으로 병렬 처리 정도는 호스트의 CPU 코어 수와 같아야 합니다. -
RMAN을 종료하고 sqlplus를 통해 oracle 사용자로 Oracle에 로그인하여 데이터베이스를 열고 복구가 완료되지 않으면 로그를 재설정합니다.

기타 복구 후 작업
Add FSx ONTAP 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 FSx ONTAP NFS 파일 시스템의 백업 이미지 복사본에서 새로운 EC2 DB 인스턴스 호스트로 Oracle VLDB 데이터베이스 복구가 완료되었습니다.
다른 사용 사례를 위해 Oracle 대기 이미지 복사본을 복제합니다.

Oracle VLDB 이미지 복사를 스테이징하기 위해 AWS FSx ONTAP 사용하는 또 다른 이점은 최소한의 추가 스토리지 투자로 여러 다른 목적으로 FlexClon을 적용할 수 있다는 것입니다. 다음 사용 사례에서는 DEV, UAT 등과 같은 다른 Oracle 사용 사례를 위해 FSx ONTAP 에서 스테이징 NFS 볼륨의 스냅샷을 생성하고 복제하는 방법을 보여줍니다.

이제 복구 프로세스는 장애 발생 후 새 EC2 DB 인스턴스로 복구하는 이전의 사용 사례와 유사합니다. 기본 프로덕션 인스턴스와 일치하도록 Oracle 환경(oratab, $ORACLE_HOME, $ORACLE_SID)을 설정하고 FSx NFS 마운트의 플래시 복구 디렉토리를 가리키는 db_recovery_file_dest_size와 db_recovery_file_dest를 포함하는 init 파일을 만듭니다. 그런 다음 RMAN을 실행하여 복구를 실행합니다. 다음은 명령 단계와 출력입니다.
