ORA-01114: IO error writing block to file string (block # string)

Cause: The device on which the file resides is probably offline. If the file is a temporary file, then it is also possible that the device has run out of space. This could happen because 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.

When you see this error message then the file can be offline or a temporary datafile did not extend completely. When you create a tempfile it doesn't initially claim all the space in the OS. so make sure the file can be accessed again or with the tempfile: drop and create the temp tablespace.
