Oracle Database 11g: Performance Tuning DBA Release 2

E-mail Imprimir PDF

O curso começa com um banco de dados desconhecidos, que exige ajuste. As aulas vão continuar com as etapas de um DBA irá realizar para adquirir as informações necessárias para identificar as áreas problemáticas para diagnosticar problemas comuns, e resolver esses problemas. A metodologia utilizada na prática é essencialmente reativa. Depois de configurar as ferramentas de monitoramento, e analisar os relatórios disponíveis, o aluno será presenteado com a arquitetura Oracle baseada no processamento da instrução SQL SELECT e DML. A seção de ajuste de SQL assume que o DBA tem pouca ou nenhuma capacidade para alterar o código. O DBA irá influenciar o desempenho do SQL com as ferramentas disponíveis. A DBA será apresentado a diversos métodos de identificar as instruções SQL que requerem um ajuste, e as ferramentas de diagnóstico necessários para encontrar maneiras de alterar o desempenho. Isto incluirá o uso de estatísticas, contornos e perfis para influenciar o otimizador, adicionando e reconstrução de índices, e usando o SQL Advisors. Uma tarefa importante do DBA é manter o desempenho do SQL em mudanças. Este curso apresenta os Replay DB, e ferramentas SQL Performance Analyzer para ajudar o teste de DBA e minimizem o impacto da mudança.

tuning Instância usa o mesmo método geral de observação de um problema, diagnosticar o problema e implementar uma solução. As aulas tuning instância cobrir os detalhes dos principais componentes ajustáveis e descrever como você pode influenciar o comportamento da instância. Para cada lição, vamos examinar os componentes relevantes da arquitetura. A única classe discute a arquitetura até o nível necessário para compreender os sintomas e soluções. Explicações mais detalhadas são deixados para outros cursos, material de referência e documentação da Oracle.

A última lição deste curso é um resumo das melhores práticas descoberto nas lições anteriores e recomendações diversas. O objetivo é terminar o curso com uma lista das melhores práticas para os alunos tirar.

Aprenda a:
Descrever a metodologia de ajuste do Oracle
Use Oracle fornecidos instrumentos de monitorização e diagnóstico de problemas de SQL e tuning Instância
consultores de banco de dados usar para corrigir problemas de desempenho de forma proativa
Identificar o problema instruções SQL e problemas ajustar o desempenho do SQL
Monitorar o desempenho Instância usando o Enterprise Manager
componentes instância Tune, principalmente utilizando os parâmetros Instância
