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. :)

> After snapshots are taken, you can generate performance reports. The SQL

> an ending snapshot ID, and a report name. The Statspack package includes
> two reports.
>
>     First, run a Statspack report, SPREPORT.SQL, which is a general
> instance health report that covers all aspects of instance performance.
> This reports calculates and prints ratios and differences for all
> statistics between the two snapshots, similar to the BSTAT/ESTAT report.
>     After examining the instance report, run a SQL report, SPREPSQL.SQL,
> on a single SQL statement (identified by its hash value). The SQL report
> only reports on data relating to the single SQL statement.

>     It is not correct to specify begin and end snapshots where the begin
> snapshot and end snapshot were taken from different instance startups. In
> other words, ***** the instance must not have been shutdown **** between
> the times that the begin and end snapshots were taken.

>     This is necessary because the database's dynamic performance tables,
> which Statspack queries to gather the data, reside in memory. Hence,
> shutting down the database resets the values in the performance tables to
> 0. Because Statspack subtracts the begin-snapshot statistics from the
> end-snapshot statistics, the resulting output is invalid. If begin and end
> snapshots taken between shutdowns are specified in the report, then the
> report shows an appropriate error to indicate this.
