Yes, but it cannot replicate everything that needs replication.ASM works well to replicate any object you can put in ASM. But you cannot put the OCR or Voting Disk in ASM.In 10gR1 they can either be mirrored using a different mechanism (which could then be used instead of ASM) or the OCR needs to be restored from backup and the Voting Disk can be recreated.In the future we are looking at providing Oracle redundancy for both.
