DESCRICcedilAtildeO

Neste artigo falaremos sobre o processo de aplicaccedilatildeo de Patch no Oracle RAC 11gR2 com zero downtime (Rolling Patch) que pode ser executado em ambientes criacuteticos onde a infraestrutura deve permanecer on-lineAntes de iniciarmos vamos explicar a diferenccedila entre PSU (Patch Set Update) CPU (Critical Patch Update) e SPU Security Patch Updates Correccedilotildees de erros criacuteticos com abertura de chamados no MOS (My Oracle Support) satildeo caracterizados como CPU e SPUO PSU eacute um pacote de correccedilotildees que a Oracle disponibiliza trimestralmente com correccedilotildees criacuteticas de seguranccedila este pacote eacute composto pelo CPU e SPU No exemplo abaixo vamos utilizar o PSU de Julho2016

Atualmente haacute 3 meacutetodos diferentes de instalaccedilatildeo de patch em ambiente Oracle RAC listados a seguir

2

33

Neste modo aplica-se o patch no servidor local em primeiro lugar depois a instalaccedilatildeo eacute iniciada nos servidores remotos e finalmente atualiza o inventaacuterio Para este caso o ambiente Oracle RAC estaraacute totalmente indisponiacutevel

bull Shutdown das instances de todos os servidoresbull Instalaccedilatildeo do patch em todos os homes de todos os

servidoresbull Startup de todas as instances de todos os servidores

INSTALANDO O PATCH COMO UacuteNICA INSTAcircNCIA (ALL-NODE PATCH)

444

Neste caso baixe o servidor primaacuterio esse servidor seraacute o primeiro a receber a aplicaccedilatildeo do patch As conexotildees seratildeo direcionadas para o servidor secundaacuterio Apoacutes a instalaccedilatildeo do patch inicie o Oracle no servidor primaacuterio As conexotildees seratildeo balanceadas e direcionadas para o servidor primaacuterio Em seguida baixe o servidor secundaacuterio esse servidor seraacute o segundo a receber a instalaccedilatildeo do patch aplica-se o patch no servidor secundaacuterio e atualize o inventaacuterio O tempo de inatividade que aconteceria entre o desligamento do servidor secundaacuterio e a inicializaccedilatildeo do servidor primaacuterio

bull Shutdown das instances do servidor 1bull Instalaccedilatildeo no home do servidor 1bull Shutdown das instances do servidor 2bull Instalaccedilatildeo no home do servidor 2bull Shutdown das instances do servidor 3bull Startup das instances nos servidores 1 e 2bull Instalaccedilatildeo no home do servidor 3bull Startup das instances no servidor 3

INSTALANDO O PATCH COM MIacuteNIMO DOWN-TIME (MIN DOWNTIME PATCH)

4

55

Com este meacutetodo natildeo haacute indisponibilidade Cada servidor seraacute atualizado com o patch individualmente enquanto todos os outros servidores estaratildeo funcionandoNeste caso move-se as conexotildees para o servidor secundaacuterio esse servidor seraacute o segundo a receber a aplicaccedilatildeo do patch Aplica-se o patch no servidor primaacuterio move-se as conexotildees do servidor secundaacuterio aplica-se o patch no servidor secundaacuterio e atualizamos o inventaacuterioEacute recomendado que apoacutes a instalaccedilatildeo do ambiente Oracle RAC seja aplicado o uacuteltimo patch disponiacutevel

bull Shutdown das instances do servidor 1bull Instalaccedilatildeo no home do servidor 1bull Startup das instances no servidor 1bull Shutdown das instances do servidor 2bull Instalaccedilatildeo no home do servidor 2bull Startup das instances no servidor 2

INSTALANDO O PATCH COM ZERO DOWNTIME (ROLLING PATCH)

Agora vamos demonstrar como instalar o PSU com zero downtime O primeiro passo eacute atualizar o OPatch que estaacute localizado no ORACLE_HOME de todos os servidores do cluster

No exemplo abaixo estamos utilizando a versatildeo 1120312 do OPatch

Temos conexatildeo na instance FOX1 do servidor RAC1 neste caso vamos instalar o PSU na instance FOX2 do servidor RAC2

Estou conectado na instance FOX1
