Visão Geral

Curso IBM Mainframe IMS Fundations, Este curso foi desenvolvido para apresentar uma introdução às facilidades básicas e aprimoradas do IMS (Sistema de Gerenciamento de Informações) e seu uso no ambiente de SI atual.

Objetivo

Após a conclusão bem sucedida deste Curso IBM Mainframe IMS Fundations , o aluno será capaz de:

• Identificar os componentes de um sistema IMS
  
• Descrever os serviços fornecidos e os blocos de controle usados ​​pelo gerenciador de banco de dados IMS
• Identifique os tipos de organização do banco de dados IMS e implementações opcionais, incluindo indexação secundária e relacionamentos lógicos
• Descrever os componentes e serviços do gerenciador de transações IMS e MFS
• Descrever o fluxo de uma mensagem através do IMS
• Identificar os componentes dos programas de aplicativos IMS DB e IMS TM
• Descrever as vantagens do IMS Fast Path e como ele difere do IMS DB/DC
• Descrever maneiras de conectar o IMS a outros sistemas
• Descrever maneiras de melhorar a disponibilidade do IMS,
• Descrever maneiras pelas quais o IMS oferece suporte à Web
• Descrever tarefas para suportar e controlar o ambiente IMS.

Publico Alvo

• Para profissionais de Tecnologia da Informação (programadores de aplicativos, administradores de banco de dados, administradores de sistemas e programadores de sistemas) que desejam um entendimento básico ou que trabalham ou gerenciam um Sistema IMS (IMS DB, IMS DB/DC ou IMS DBCTL).
  

Pre-Requisitos

• Um conhecimento introdutório de hardware e software de Sistemas Empresariais.
