Abstract

"SISTEMA DE COMPUTADOR TOLERANTE à FALHA, E, PROCESSO DE OPERAçãO TOLERANTE à FALHA DE UM SISTEMA DE COMPUTADOR". Um sistema de computador com tolerância à falha e processo exigindo comunicações entre unidades reduzidas. Um sistema primário é disposto para executar processos de evento em resposta a comandos recebidos. Toda vez que a execução de um processo de evento é interrompida, devido ao encerramento normal ou a uma interrupção, um gerador de evento gera uma mensagem de evento indicando o tipo de processo de evento e a razão ou tempo de interrupção de processo de evento. A mensagem de evento é utilizada para instruir um sistema de reserva a executar o mesmo processo de evento. Visto que a mensagem de evento também especifica a razão e o tempo de interrupção do processo de evento, a execução do processo de evento pode ser replicada no sistema de reserva. Dessa forma, o sistema primário e pelo menos um sistema de reserva serão sincronizados. Pelo menos um sistema de espera pode ser fornecido para registrar em um registro de evento a seg³ência de mensagens de evento, e para armazenar uma cópia de arquivo de conteúdo de memória do sistema primário. O registro de evento com a cópia de arquivo devem ser utilizados para restaurar o estado do sistema primário.
