Finished recover at 27-JUL-09
No meu blog eu coloquei alguns exemplos.
Mas são utilizando o RMAN.
Mais ainda acho que vc precisa ler mais,
antes de partir para prática.
O banco pede arcuives que não existe pois vc está fazendo uma recuperação completa.
Nesse caso vc vai ter que ficar dando alter system swtich lofile varias vezes ou abrir a base com open resetlogs.
