Instalando e usando o Remote Diagnostic Agent (RDA) - Linux/Unix

O Oracle Remote Diagnostics Agent (RDA) é uma ferramenta de suporte, composta por um conjunto de aplicativos e scripts para análise e diagnóstico de produtos Oracle. Tendo como principal objetivo o auxilio na coleta de informações (SO, rede, database, etc ) do ambiente, para diagnóstico e solução de problemas.

Uma grande vantagem da utilização do RDA é minimizar o tempo para inicio do atendimento e resolução de um chamado My Oracle Support, uma vez que permite o envio de informações completas, evitando a constante troca de informações com o suporte técnico da Oracle.

O RDA é bastante útil, principalmente em chamados tipo: 
  • Acquired company product issues
  • Developer issues
  • Installation/configuration issues
  • ORA-600, ORA-7445, ORA-3113, ORA-4030 and ORA-4031 errors
  • Oracle Database issues
  • Oracle Application Server/Fusion Middleware issues
  • Oracle Collaboration products (Oracle Collaboration Suite and Oracle Beehive) issues
  • Oracle Application issues
  • Other corrective issues
  • Performance issues
  • Upgrade, migration, and linking issues
O download do RDA, bem como a documentação detalhada pode ser realizado através do my oracle support - Doc ID 314422.1 e Doc ID 250262.1.

Atualmente o RDA é suportado pelas seguintes plataformas:

  • Apple Mac OS X/Darwin
  • HP OpenVMS Alpha 7.3-2 and above
  • HP OpenVMS Itanium
  • HP Tru64 UNIX
  • HP-UX Itanium
  • HP-UX PA-RISC (32 and 64 bit)
  • IBM AIX on POWER Systems(32 and 64 bit)
  • IBM Dynix/Ptx
  • IBM Linux on POWER
  • IBM zSeries Based Linux
  • Linux Itanium
  • Linux x86 (32 and 64 bit)
  • Microsoft Windows 7
  • Microsoft Windows 2000 Workstation and Server
  • Microsoft Windows 2003 Server
  • Microsoft Windows 2008
  • Microsoft Windows 2012
  • Microsoft Windows Vista
  • Microsoft Windows XP Professional
  • Sun Solaris Intel
  • Sun Solaris SPARC (32 and 64 bit)
Plataforma não suportada:
  • IBM Z/OS (OS/390)
Neste artigo abordarei exemplos das plataformas Unix e executarei o processo com o usuário de SO que foi utilizado para a instalação do Oracle. Em meu caso o usuário é Oracle.

Feito o download da instalação, o mesmo será enviado ao servidor onde será descompactado.

No exemplo acima, devido a quantidade de informação gerado no output da descompactação, apresentei apenas as primeiras linhas.

Realizada a descompactação, podemos acessar o diretório rda, que foi criado no processo de descompactação e executar o comando ./<rda> -cv para validar o processo de instalação.
 [oracle@lamimtst Lamim]$ cd rda/

Ao termino da execução do processo, temos um resumo dos resultados dos testes realizados, além do nome e diretório onde está localizado o arquivo HTML que foi gerado pelo processo. Este é o arquivo que deve ser anexado aos chamados com a Oracle.

Também é possivel realizar uma coleta mais detalhada e profunda de todo o ambiente e o aquivo gerado é bastante útil ao analisarmos um ambiente. Para isso basta termos o perl habilitado no PATH do usuário e executar o comando perl rda.pl -v. Este comando questionara vários aspectos do ambiente que devem ser respondidos para que a análise seja realizada. Abaixo mostro as primeiras linhas desta execução.
