Allen Cao, Niyaz Mohamed, NetApp
Esta solução fornece uma visão geral e detalhes para recuperação rápida e clonagem do Oracle VLDB implantado na instância de computação AWS EC2 com montagem NFS no FSx ONTAP para preparar uma cópia de arquivo de dados em espera para ser mesclada incrementalmente de forma constante via RMAN.
Propósito
Recuperar um banco de dados muito grande (VLDB) no Oracle usando a ferramenta de backup Oracle Recovery Manager (RMAN) pode ser uma tarefa altamente desafiadora. O processo de restauração do banco de dados a partir da mídia de backup em caso de falha pode ser demorado, atrasando a recuperação do banco de dados e potencialmente impactando significativamente seu Contrato de Nível de Serviço (SLA). No entanto, a partir da versão 10g, a Oracle introduziu um recurso RMAN que permite aos usuários criar cópias de imagem preparadas dos arquivos de dados do banco de dados Oracle em armazenamento em disco adicional localizado no host do servidor de banco de dados. Essas cópias de imagem podem ser atualizadas incrementalmente usando o RMAN diariamente. Em caso de falha, o administrador do banco de dados (DBA) pode alternar rapidamente o banco de dados Oracle da mídia com falha para a cópia de imagem, eliminando a necessidade de uma restauração completa da mídia do banco de dados. O resultado é um SLA muito melhorado, embora ao custo de dobrar o armazenamento de banco de dados necessário.
Se você estiver interessado no SLA para seu VLDB e pensando em mover o banco de dados Oracle para uma nuvem pública, como a AWS, você pode configurar uma estrutura de proteção de banco de dados semelhante usando recursos como o AWS FSx ONTAP para preparar sua cópia de imagem do banco de dados standby. Nesta documentação, demonstramos como provisionar e exportar um sistema de arquivos NFS do AWS FSx ONTAP para ser montado em um servidor de banco de dados Oracle para preparar uma cópia de banco de dados em espera para recuperação rápida em caso de falha de armazenamento primário.
Melhor ainda, também mostramos como você pode aproveitar o NetApp FlexClone para criar uma cópia do mesmo sistema de arquivos NFS de preparação para outros casos de uso, como configurar um ambiente Oracle de desenvolvimento/teste com essa mesma cópia de imagem de banco de dados de espera sem investimento adicional em armazenamento.
Esta solução aborda os seguintes casos de uso:
-
Uma fusão incremental de cópia de imagem Oracle VLDB via RMAN no ponto de montagem NFS do armazenamento AWS FSx ONTAP .
-
Recuperação rápida de um Oracle VLDB alternando para cópia de imagem de banco de dados no armazenamento FSx ONTAP em caso de falha.
-
Clone o volume do sistema de arquivos FSx ONTAP NFS armazenando uma cópia de imagem Oracle VLDB a ser usada para configurar outra instância de banco de dados para outros casos de uso.
Público
Esta solução é destinada às seguintes pessoas:
-
Um DBA que configurou a mesclagem incremental de cópias de imagem do Oracle VLDB via RMAN na AWS para recuperação mais rápida do banco de dados.

Fatores-chave para consideração de implantação
-
Layout de armazenamento Oracle VLDB para mesclagem incremental RMAN. Em nossos testes e validações, o volume NFS para backup incremental e mesclagem do Oracle é alocado a partir de um único sistema de arquivos FSx, que tem taxa de transferência de 4 GBps, 160.000 IOPS SSD brutos e limite de capacidade de 192 TiB. Para implantação acima dos limites, vários sistemas de arquivos FSx podem ser concatenados em paralelo com vários pontos de montagem NFS para fornecer maior capacidade.
-
Recuperação do Oracle usando mesclagem incremental do RMAN. O backup incremental e a mesclagem do RMAN geralmente são executados na frequência definida pelo usuário com base nos seus objetivos de RTO e RPO. Se houver perda total do armazenamento de dados primários e/ou logs arquivados, poderá ocorrer perda de dados. O banco de dados Oracle pode ser recuperado até o último backup incremental disponível na cópia de imagem de backup do banco de dados FSx. Para minimizar a perda de dados, a área de recuperação flash do Oracle pode ser configurada no ponto de montagem do FSx NFS e os logs arquivados podem ser copiados para a montagem do FSx NFS junto com a cópia da imagem do banco de dados.
-
Executando Oracle VLDB no sistema de arquivos FSx NFS. Diferentemente de outros armazenamentos em massa para backup de banco de dados, o AWS FSx ONTAP é um armazenamento de nível de produção habilitado para nuvem que oferece alto nível de desempenho e eficiência de armazenamento. Depois que o Oracle VLDB alterna do armazenamento primário para a cópia de imagem no sistema de arquivos FSx ONTAP NFS, o desempenho do banco de dados pode ser mantido em alto nível enquanto a falha do armazenamento primário é resolvida. Você pode ficar tranquilo sabendo que a experiência do aplicativo do usuário não é afetada por falhas no armazenamento primário.
-
* Cópia de imagem FlexClone Oracle VLDB do volume NFS para outros casos de uso.* O AWS FSx ONTAP FlexClone fornece cópias compartilhadas do mesmo volume de dados NFS que são graváveis. Dessa forma, eles podem ser usados para muitos outros casos de uso, mantendo a integridade da cópia de imagem do Oracle VLDB de preparação, mesmo quando o banco de dados Oracle é alternado. Isso proporciona uma tremenda economia de custos de armazenamento ao reduzir substancialmente o espaço de armazenamento do VLDB. A NetApp recomenda minimizar as atividades do FlexClone no caso de troca do banco de dados do armazenamento primário para a cópia de imagem do banco de dados, a fim de manter o desempenho do Oracle em alto nível.
-
Instâncias de computação do EC2. Nesses testes e validações, usamos uma instância t2.xlarge do AWS EC2 como instância de computação do banco de dados Oracle. A NetApp recomenda usar uma instância EC2 do tipo M5 como instância de computação para Oracle na implantação de produção porque ela é otimizada para carga de trabalho de banco de dados. Você precisa dimensionar a instância do EC2 adequadamente para o número de vCPUs e a quantidade de RAM com base nos requisitos reais da carga de trabalho.
-
Implantação de clusters de HA de armazenamento FSx em uma ou várias zonas. Nesses testes e validações, implantamos um cluster FSx HA em uma única zona de disponibilidade da AWS. Para implantação de produção, a NetApp recomenda implantar um par FSx HA em duas zonas de disponibilidade diferentes. Um cluster FSx HA é sempre provisionado em um par HA que é espelhado de forma sincronizada em um par de sistemas de arquivos ativos-passivos para fornecer redundância em nível de armazenamento. A implantação em várias zonas aumenta ainda mais a alta disponibilidade em caso de falha em uma única zona da AWS.
-
Dimensionamento do cluster de armazenamento FSx. Um sistema de arquivos de armazenamento Amazon FSx ONTAP fornece até 160.000 IOPS SSD brutos, taxa de transferência de até 4 GBps e capacidade máxima de 192 TiB. No entanto, você pode dimensionar o cluster em termos de IOPS provisionados, taxa de transferência e limite de armazenamento (mínimo de 1.024 GiB) com base nos seus requisitos reais no momento da implantação. A capacidade pode ser ajustada dinamicamente sem afetar a disponibilidade do aplicativo.
-
Configuração do dNFS. O dNFS é integrado ao kernel do Oracle e é conhecido por aumentar drasticamente o desempenho do banco de dados Oracle quando o Oracle é implantado no armazenamento NFS. O dNFS é empacotado no binário do Oracle, mas não é ativado por padrão. Ele deve ser ativado para qualquer implantação de banco de dados Oracle no NFS. Para implantação de vários sistemas de arquivos FSx para um VLDB, o multicaminho dNFS para diferentes sistemas de arquivos FSx NFS deve ser configurado corretamente.
Implantação da solução
Supõe-se que você já tenha seu Oracle VLDB implantado no ambiente AWS EC2 dentro de uma VPC. Se precisar de ajuda na implantação do Oracle na AWS, consulte os seguintes relatórios técnicos para obter ajuda.
Seu Oracle VLDB pode ser executado em um FSx ONTAP ou em qualquer outro armazenamento de escolha dentro do ecossistema AWS EC2. A seção a seguir fornece procedimentos de implantação passo a passo para configurar a mesclagem incremental do RMAN em uma cópia de imagem de um Oracle VLDB que está sendo preparado em uma montagem NFS do armazenamento AWS FSx ONTAP .
Pré-requisitos para implantação
Details
A implantação requer os seguintes pré-requisitos.
-
Uma conta da AWS foi configurada e os segmentos de VPC e rede necessários foram criados dentro da sua conta da AWS.
-
No console do AWS EC2, você deve implantar duas instâncias do EC2 Linux, uma como o servidor Oracle DB principal e um servidor de DB de destino clone alternativo opcional. Veja o diagrama de arquitetura na seção anterior para obter mais detalhes sobre a configuração do ambiente. Revise também o"Guia do usuário para instâncias Linux" para maiores informações.
-
No console do AWS EC2, implante clusters de HA de armazenamento do Amazon FSx ONTAP para hospedar os volumes NFS que armazenam a cópia da imagem de espera do banco de dados Oracle. Se você não estiver familiarizado com a implantação do armazenamento FSx, consulte a documentação"Criação de sistemas de arquivos FSx ONTAP" para obter instruções passo a passo.
-
As etapas 2 e 3 podem ser executadas usando o seguinte kit de ferramentas de automação do Terraform, que cria uma instância EC2 denominada
ora_01e um sistema de arquivos FSx chamadofsx_01. Revise as instruções cuidadosamente e altere as variáveis para adequá-las ao seu ambiente antes da execução. O modelo pode ser facilmente revisado para atender às suas próprias necessidades de implantação.git clone https://github.com/NetApp-Automation/na_aws_fsx_ec2_deploy.git
|
Certifique-se de ter alocado pelo menos 50 GB no volume raiz da instância do EC2 para ter espaço suficiente para preparar os arquivos de instalação do Oracle. |
Provisionar e exportar volume NFS para ser montado no host da instância do EC2 DB
Details
Nesta demonstração, mostraremos como provisionar um volume NFS a partir da linha de comando, efetuando login em um cluster FSx via ssh como usuário fsxadmin por meio do IP de gerenciamento do cluster FSx. Como alternativa, o volume também pode ser alocado usando o console do AWS FSx. Repita os procedimentos em outros sistemas de arquivos FSx se mais de um sistema de arquivos FSx estiver configurado para acomodar o tamanho do banco de dados.
-
Primeiro, provisione o volume NFS via CLI efetuando login no cluster FSx via SSH como o usuário fsxadmin. Altere o endereço IP de gerenciamento do cluster FSx, que pode ser recuperado no console da interface do usuário do AWS FSx ONTAP .
ssh fsxadmin@172.30.15.53 -
Crie um volume NFS do mesmo tamanho do seu armazenamento primário para armazenar uma cópia da imagem dos arquivos de dados do banco de dados Oracle VLDB primário.
vol create -volume ora_01_copy -aggregate aggr1 -size 100G -state online -type RW -junction-path /ora_01_copy -snapshot-policy none -tiering-policy snapshot-only -
Como alternativa, o volume pode ser provisionado a partir da interface do usuário do console AWS FSx com opções: eficiência de armazenamento
Enabled, estilo de segurançaUnix, Política de instantâneoNone, e níveis de armazenamentoSnapshot Onlycomo mostrado abaixo.
-
Crie uma política de snapshot personalizada para o banco de dados Oracle com uma programação diária e retenção de 30 dias. Você deve ajustar a política para atender às suas necessidades específicas em termos de frequência de snapshots e janela de retenção.
snapshot policy create -policy oracle -enabled true -schedule1 daily -count1 30Aplique a política ao volume NFS provisionado para backup incremental e mesclagem do RMAN.
vol modify -volume ora_01_copy -snapshot-policy oracle -
Efetue login na instância do EC2 como ec2-user e crie um diretório /nfsfsxn. Crie diretórios de ponto de montagem adicionais para sistemas de arquivos FSx adicionais.
sudo mkdir /nfsfsxn -
Monte o volume FSx ONTAP NFS no host da instância do EC2 DB. Altere o endereço NFS lif do seu servidor virtual FSx. O endereço NFS lif pode ser recuperado do console FSx ONTAP UI.
sudo mount 172.30.15.19:/ora_01_copy /nfsfsxn -o rw,bg,hard,vers=3,proto=tcp,timeo=600,rsize=262144,wsize=262144,nointr -
Altere a propriedade do ponto de montagem para oracle:oisntall, altere seu nome de usuário Oracle e grupo primário conforme necessário.
sudo chown oracle:oinstall /nfsfsxn
Configurar mesclagem incremental do Oracle RMAN para cópia de imagem no FSx
Details
A mesclagem incremental do RMAN atualiza a cópia da imagem dos arquivos de dados do banco de dados de preparação continuamente em cada intervalo de backup/mesclagem incremental. A cópia da imagem do backup do banco de dados será tão atualizada quanto a frequência com que você executa o backup/mesclagem incremental. Portanto, leve em consideração o desempenho do banco de dados, seus objetivos de RTO e RPO ao decidir a frequência de backup incremental e mesclagem do RMAN.
-
Efetue login na instância EC2 do servidor de banco de dados primário como usuário Oracle
-
Crie um diretório oracopy no ponto de montagem /nfsfsxn para armazenar cópias de imagem de arquivos de dados Oracle e um diretório archlog para a área de recuperação do Oracle Flash.
mkdir /nfsfsxn/oracopymkdir /nfsfsxn/archlog -
Efetue login no banco de dados Oracle via sqlplus, habilite o rastreamento de alterações de bloco para backup incremental mais rápido e altere a área de recuperação do Oracle Flash para montagem FSx ONTAP se ela estiver atualmente no armazenamento primário. Isso permite que o backup automático do arquivo de controle padrão/spfile do RMAN e os logs arquivados sejam copiados para a montagem FSx ONTAP NFS para recuperação.
sqlplus / as sysdbaNo prompt do sqlplus, execute o seguinte comando.
alter database enable block change tracking using file '/nfsfsxn/oracopy/bct_db1.ctf'alter system set db_recovery_file_dest='/nfsfsxn/archlog/' scope=both; -
Crie um backup do RMAN e um script de mesclagem incremental. O script aloca vários canais para backup e mesclagem RMAN paralelos. A primeira execução geraria a cópia inicial completa da imagem de base. Em uma execução completa, ele primeiro limpa os backups obsoletos que estão fora da janela de retenção para manter a área de preparação limpa. Em seguida, ele alterna o arquivo de log atual antes da mesclagem e do backup. O backup incremental segue a mesclagem para que a cópia da imagem do banco de dados fique atrás do estado atual do banco de dados em um ciclo de backup/mesclagem. A ordem de mesclagem e backup pode ser revertida para uma recuperação mais rápida, de acordo com a preferência do usuário. O script RMAN pode ser integrado a um script de shell simples para ser executado a partir do crontab no servidor de banco de dados primário. Certifique-se de que o backup automático do arquivo de controle esteja ativado na configuração do RMAN.

Isso conclui a configuração do backup e da mesclagem da cópia de imagem de espera do banco de dados Oracle.
Mude o Oracle DB para cópia de imagem para recuperação rápida
Details
No caso de uma falha devido a um problema de armazenamento primário, como perda ou corrupção de dados, o banco de dados pode ser rapidamente alternado para uma cópia de imagem na montagem FSx ONTAP NFS e recuperado para o estado atual sem restauração do banco de dados. Eliminar a restauração de mídia acelera tremendamente a recuperação do banco de dados para um VLDB. Este caso de uso pressupõe que a instância do host do banco de dados esteja intacta e que o arquivo de controle do banco de dados, os logs arquivados e os atuais estejam disponíveis para recuperação.

Efetue login no host do servidor EC2 DB como usuário Oracle e crie uma tabela de teste antes da troca.

Você pode executar o banco de dados Oracle na montagem FSx NFS por um longo período sem perda de desempenho porque o FSx ONTAP é um armazenamento redundante de nível de produção que oferece alto desempenho. Quando o problema de armazenamento primário for corrigido, você poderá retornar a ele revertendo os processos de mesclagem de backup incremental com tempo de inatividade mínimo.
Recuperação de banco de dados Oracle a partir de cópia de imagem para host de instância de banco de dados EC2 diferente
Details
Em caso de falha quando o armazenamento primário e o host da instância do EC2 DB são perdidos, a recuperação não pode ser realizada a partir do servidor original. Felizmente, você ainda tem uma cópia de imagem de backup do banco de dados Oracle no sistema de arquivos FSx ONTAP NFS redundante. Você pode provisionar rapidamente outra instância idêntica do EC2 DB e montar facilmente a cópia da imagem do seu VLDB no novo host do EC2 DB via NFS para executar a recuperação. Nesta seção, demonstraremos os procedimentos passo a passo para fazer isso.
-
Insira uma linha para testar a tabela que criamos anteriormente para restauração do banco de dados Oracle para validação de host alternativo.

Desligue o host da instância primária do EC2 DB para simular uma falha total do armazenamento e do host do servidor do BD.
-
Privilegiar um novo host de instância de banco de dados EC2 ora_02 com o mesmo sistema operacional e versão por meio do console AWS EC2. Configure o kernel do sistema operacional com os mesmos patches do host do servidor de banco de dados EC2 primário, o RPM de pré-instalação da Oracle e adicione espaço de swap ao host também. Instale a mesma versão e os mesmos patches do Oracle que no host do servidor de banco de dados EC2 primário com a opção somente software. Essas tarefas podem ser automatizadas com o kit de ferramentas de automação da NetApp , disponível nos links abaixo.
Kit de ferramentas:"na_oracle19c_deploy" Documentação:"Implantação automatizada do Oracle19c para ONTAP no NFS"
-
Configure o ambiente Oracle de forma semelhante ao host da instância primária do EC2 DB ora_01, como oratab, oraInst.loc e usuário Oracle .bash_profile. É uma boa prática fazer backup desses arquivos no ponto de montagem FSx ONTAP NFS.
-
A cópia da imagem de backup do banco de dados Oracle na montagem FSx ONTAP NFS é armazenada em um cluster FSx que abrange zonas de disponibilidade da AWS para redundância, alta disponibilidade e alto desempenho. O sistema de arquivos NFS pode ser facilmente montado em um novo servidor, desde que a rede seja acessível. Os procedimentos a seguir montam a cópia de imagem de um backup do Oracle VLDB no host da instância do EC2 DB recém-provisionado para recuperação.
Como usuário ec2, crie o ponto de montagem.
sudo mkdir /nfsfsxnComo usuário ec2, monte o volume NFS que armazenou a cópia da imagem de backup do Oracle VLDB.
sudo mount 172.30.15.19:/ora_01_copy /nfsfsxn -o rw,bg,hard,vers=3,proto=tcp,timeo=600,rsize=262144,wsize=262144,nointr -
Valide a cópia da imagem de backup do banco de dados Oracle no ponto de montagem FSx ONTAP NFS.

Para uma recuperação mais rápida, habilite sessões paralelas com o parâmetro recovery_parallelism ou especifique o grau de paralelismo no comando de recuperação para recuperação de banco de dados: RECOVER DATABASE PARALLEL (DEGREE d INSTANCES DEFAULT);. Em geral, os graus de paralelismo devem ser iguais ao número de núcleos de CPU no host. -
Saia do RMAN, efetue login no Oracle como usuário oracle via sqlplus para abrir o banco de dados e redefinir o log após uma recuperação incompleta.

Outras tarefas de recuperação pós-processamento
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.
Isso conclui a recuperação do banco de dados Oracle VLDB da cópia de imagem de backup no sistema de arquivos FSx ONTAP NFS para um novo host de instância de banco de dados EC2.
Clonar cópia de imagem de espera do Oracle para outros casos de uso
Details
Outro benefício de usar o AWS FSx ONTAP para preparar uma cópia de imagem Oracle VLDB é que ele pode ser FlexClonado para atender a muitos outros propósitos com investimento mínimo em armazenamento adicional. No caso de uso a seguir, demonstramos como fazer um snapshot e clonar o volume NFS de preparação no FSx ONTAP para outros casos de uso do Oracle, como DEV, UAT, etc.

Os processos de recuperação agora são semelhantes ao caso de uso anterior de recuperação para uma nova instância de banco de dados EC2 após uma falha - defina o ambiente Oracle (oratab, $ORACLE_HOME, $ORACLE_SID) para corresponder à instância de produção primária, crie um arquivo init incluindo db_recovery_file_dest_size e db_recovery_file_dest que apontam para o diretório de recuperação flash na montagem FSx NFS. Em seguida, inicie o RMAN para executar a recuperação. A seguir estão as etapas do comando e a saída.
