ORA-01114

I/O error writing block to file data_file (block # block_number) during RMAN restore operation.
  • data_file: The file being restored.
  • block_number: The block number being written to the data file.

Cause

The device on which the file resides may be offline. If the file is a temporary file, then it can also be that the device has run out of space. This can happen because the disk space of temporary files is not necessarily allocated at file creation time.


Action

Restore access to the device or remove unnecessary files to free up space.
