Uma ação paliativa para garantir pelo menos o backup é utilizar a sintaxe “SET MAXCORRUPT for datafile ” para o datafile que está corrompido. Com isso , o backup terminará sem erros. No entanto, a corrupção dos blocos permanecerá.
Execução com a sintaxe “SET MAXCORRUPT” no backup. Note que coloquei o ID do datafile que apresentou erro, no caso 118, e o número aceitável de até 4 blocos corrompidos.
