Chiappa, é 9i sim, sei que tem apenas statspack. O que acontece é que temos uma rotina que gera o statspack para cada dois períodos (id's) e os armazena em disco, justamente por isso, com um período de retenção de 7 dias. De qualquer forma o statspack não demonstrou nada anormal no período anterior ao sinistro. Mistério continua parte 2. :)
