Ksplice no Exadata
Updated
•29 min read
Normalmente quando precisamos corrigir qualquer problema no Kernel/OS do Exadata aplicamos o bundle patch de OS do exadata para corrigir o problema, mas você pode encontrar um bug/problema específico que já foi reconhecido pelo ksplice ou que a equipe de suporte da Oracle acabou de solucionar e já publicou no ksplice para resolver o “seu” problema.
Alguns alertas:
Ksplice offline updates may be installed on database nodes only.
Ksplice offline updates are supported for Exadata images 12.1.1.1.2 and later.
Ksplice offline updates are supported only for kernel updates. Exadata does not support ksplice updates for user space packages.
Este é um procedimento que o próprio suporte da Oracle (Doc ID 2207063.1) vai pedir para executá-lo, então execute-o apenas quando for requisitado pelo Suporte Oracle. A razão mais comum pela qual a instalação do ksplice falha é que um ou mais módulos do kernel proprietários são carregados por um produto de segurança de terceiros que modificou o kernel de uma forma que entra em conflito com uma correção do ksplice recebida. O seguinte comando mostra módulos de kernel proprietários carregados:
[root@dbm0db02 ~]# grep -l P /sys/module/*/taint | cut -f4 -d/ | egrep -v 'oracle(acfs|advm|oks)'
[root@dbm0db02 ~]#
Se não retornar nada podemos iniciar, caso retorne, favor consulte a nota 2207063.1.
Considerando que o procedimento anterior foi executado com sucesso, vamos iniciar o procedimento.
1º vamos acessar o site: https://linux.oracle.com (Logue com a conta da sua organização).
2º Vá em Channels
3 º Selecione a arquitetura:
4 º Procure pelo pacote “Ksplice for Oracle Linux (x86_64)”
5º Depois de clicar em Ksplice for Oracle Linux 7 (x86_64), clique em Channel packages.
6º Agora vamos baixar o pacote exato do seu kernel atual:
[root@dbm0db02 ~]# uname -r
4.14.35-1902.303.5.3.el7uek.x86_64
Vamos dar um CTRL+F e baixar exatamente o package que contem o resultado do “uname -r”
Transfira para o dbnodes e vamos iniciar o procedimento:
[root@dbm0db02 ~]# ll -rths

Como a nota 2207063.1 recomenda, antes de iniciarmos a instalação do ksplice precisamos remover o pacote “exadata-sun.*computenode-exact”.
