WHAT IS RMAN ?
Recovery Manager is a tool that: manages the process of creating backups and
also manages the process of restoring and recovering from them.
WHY USE RMAN ?
· No extra costs. Its available free
· RMAN introduced in Oracle 8 it has become simpler with newer versions
and easier than user managed backups
· Proper security
· You are 100% sure your database has been backed up.
· Its contains detail of the backups taken etc in its central repository
Facility for testing validity of backups also commands like crosscheck to
check the status of backup.
· Faster backups and restores compared to backups without RMAN
RMAN is the only backup tool which supports incremental backups.
Oracle 10g has got further optimized incremental backup which has
resulted in improvement of performance during backup and recovery time
· Parallel operations are supported
· Better querying facility for knowing different details of backup
· No extra redo generated when backup is taken..compared to online
backup without RMAN which results in saving of space in hard disk
· RMAN an intelligent tool
Maintains repository of backup metadata
Remembers backup set location
Knows what need to backed up
Knows what is required for recovery
Knows what backup are redundant

Hi, folks! I am new to RMAN and now trying to configure it. There is one issue concerning me. Let's say I backup the target database every 6:PM and the database generates about 100 archived logs every day. So what happens if the database crashs at 5PM? I have the backup at 6PM of the last day only and no backup of archive logs generated between that time. Have anynone experienced that any what is your solution?
