Uma informação bastante útil para quem trabalha com mainframe é acompanhar o percentual de utilização da CPU. E o TSO oferece recursos que permitem consultar esse consumo diretamente no ambiente, sem a necessidade de utilizar uma ferramenta externa. Além de verificar o percentual de utilização da CPU, também é possível analisar quais jobs, tarefas ou aplicações estão consumindo mais recursos do processador. Essa informação é muito importante para identificar situações de alto consumo e ajudar na investigação de possíveis problemas de desempenho. Neste post, vamos mostrar como consultar pelo TSO o uso da CPU do mainframe e como identificar qual aplicação ou tarefa está sendo responsável pelo maior consumo de processamento.
No TSO esses foram os comandos realizados;
Acessando o TSO - Opção SD.DA
PREFIX *
SORT CPU% D
Tecle PF11 uma vez
Agora vai mostrar quem esta consumindo mais CPU% pela ordem - neste dia foi o banco AAFAI240 que estava mais consumindo (normal)
Ocorreu uma vez de ficar lento - estava rodando a proc do SMF
Ocorreu outra vez do complete estar usando muito a CPU, foi reciclado o complete e melhorou a performance
