1 1 INSTALANDO PATCH NO ORACLE RAC 11GR2 COM ZERO DOWNTIME Renan Parisotto

2 2 DESCRIÇÃO Neste artigo falaremos sobre o processo de aplicação de Patch no Oracle RAC 11gR2 com zero downtime (Rolling Patch) que pode ser executado em ambientes críticos onde a infraestrutura deve permanecer on-line. Antes de iniciarmos vamos explicar a diferença entre PSU (Patch Set Update), CPU (Critical Patch Update) e SPU Security Patch Updates. Correções de erros críticos com abertura de chamados no MOS (My Oracle Support) são caracterizados como CPU e SPU. O PSU é um pacote de correções que a Oracle disponibiliza trimestralmente com correções críticas de segurança; este pacote é composto pelo CPU e SPU. No exemplo abaixo vamos utilizar o PSU de Julho/2016. Atualmente há 3 métodos diferentes de instalação de patch em ambiente Oracle RAC, listados a seguir.

3 3 INSTALANDO O PATCH COMO ÚNICA INSTÂNCIA (ALL-NODE PATCH) Neste modo, aplica-se o patch no servidor local em primeiro lugar, depois a instalação é iniciada nos servidores remotos e finalmente atualiza o inventário. Para este caso, o ambiente Oracle RAC estará totalmente indisponível. Shutdown das instances de todos os servidores; Instalação do patch em todos os homes de todos os servidores; Startup de todas as instances de todos os servidores.

4 4 INSTALANDO O PATCH COM MÍNIMO DOWN-TIME (MIN. DOWNTIME PATCH) Neste caso, baixe o servidor primário; esse servidor será o primeiro a receber a aplicação do patch. As conexões serão direcionadas para o servidor secundário. Após a instalação do patch, inicie o Oracle no servidor primário. As conexões serão balanceadas e direcionadas para o servidor primário. Em seguida baixe o servidor secundário; esse servidor será o segundo a receber a instalação do patch, aplica-se o patch no servidor secundário e atualize o inventário. O tempo de inatividade que aconteceria entre o desligamento do servidor secundário e a inicialização do servidor primário. Shutdown das instances do servidor 1; Instalação no home do servidor 1; Shutdown das instances do servidor 2; Instalação no home do servidor 2; Shutdown das instances do servidor 3; Startup das instances nos servidores 1 e 2; Instalação no home do servidor 3; Startup das instances no servidor 3.

5 5 INSTALANDO O PATCH COM ZERO DOWNTIME (ROLLING PATCH) Com este método, não há indisponibilidade. Cada servidor será atualizado com o patch individualmente enquanto todos os outros servidores estarão funcionando. Neste caso, move-se as conexões para o servidor secundário, esse servidor será o segundo a receber a aplicação do patch. Aplica-se o patch no servidor primário, move-se as conexões do servidor secundário, aplica-se o patch no servidor secundário e atualizamos o inventário. É recomendado que após a instalação do ambiente Oracle RAC seja aplicado o último patch disponível. Shutdown das instances do servidor 1; Instalação no home do servidor 1; Startup das instances no servidor 1; Shutdown das instances do servidor 2; Instalação no home do servidor 2; Startup das instances no servidor 2. No link abaixo você poderá encontrar mais informações sobre os patchs.

6 6 Agora vamos demonstrar como instalar o PSU com zero downtime. O primeiro passo é atualizar o que está localizado no ORACLE_ HOME de todos os servidores do cluster. No exemplo abaixo, estamos utilizando a versão do [oracle@rac1 Version: ~]$ opatch version succeeded. Version: [oracle@rac2 ~]$ succeeded. opatch version [oracle@rac2 Version: ~]$ opatch version succeeded. Version: succeeded. Temos conexão na instance FOX1 do servidor RAC1, neste caso vamos instalar o PSU na instance FOX2 do servidor RAC2. Estou conectado na instance FOX1. Version: select instance_name from v$instance; succeeded. [oracle@rac2 ~]$ opatch version INSTANCE_NAME Version: succeeded.

7 7 Baixando o CRS no servidor RAC2. [root@rac2 Version: ~]# crsctl stop crs CRS-2791: succeeded. Starting shutdown of Oracle High Availability Services-managed resources [oracle@rac2 on rac2 ~]$ opatch version CRS-2673: Version: Attempting to stop ora.crsd on rac2 CRS-2790: succeeded.
