Answer / vivek tiwari
Noarchivelog Mode
By default, a database is created in Noarchivelog mode. The
characteristics of operating a
database in Noarchivelog mode are as follows:
• Redo log files are used in a circular fashion.
• A redo log file can be reused immediately after a
checkpoint has taken place.
• After redo logs are overwritten, media recovery is only
possible to the last full backup.
Archivelog Mode
A filled redo log file cannot be reused until a checkpoint
has taken place and the redo log file
has been backed up by the ARCn background process. An entry
in the control file records the
log sequence number of the archived log file.
The most recent changes to the database are available at
any time for instance recovery, and
the archived redo log files can be used for media recovery.
