Since 184.108.40.206 there’s a new parameter, “_datafile_write_errors_crash_instance” to prevent the intance to crash when a write error on a datafile occurs . But.. should I use this or not. The official text of this parameter:
This fix introduces a notable change in behaviour in that
from 220.127.116.11 onwards an I/O write error to a datafile will
now crash the instance.
Before this fix I/O errors to datafiles not in the system tablespace
offline the respective datafiles when the database is in archivelog mode.
This behavior is not always desirable. Some customers would prefer
that the instance crash due to a datafile write error.
