Data Recovery Advisor can diagnose failures such as the following:
– Components such as datafiles and control files that are not accessible because they do not exist, do not have the correct access permissions, have been taken offline, and so on
– Physical corruptions such as block checksum failures and invalid block header field values
– Inconsistencies such as a datafile that is older than other database files
– I/O failures such as hardware errors, operating system driver failures, and exceeding operating system resource limits (for example, the number of open files)
