What is the recovery window in RMAN?
RMAN Recovery Window Retention Policy It is always important to have backups of the database.

What is an incremental backup in Oracle RMAN?
RMAN incremental backups back up only datafile blocks that have changed since a specified previous backup. You can make incremental backups of databases, individual tablespaces or datafiles. The goal of an incremental backup is to back up only those data blocks that have changed since a previous backup.
Does RMAN backup, restore temp files?
To my knowledge, RMAN does not explicitly recreate temp files. You have to recreate them yourself if the control file was restored and or the temp files were missing or damaged. Note: RMAN does not backup tempfiles because there’s nothing of value there to backup.
Can not recover table from RMAN backup?
Answer: You cannot recover a single table using RMAN directly, but you need to restore into a TEST database and then use export (data pump expdp) to extract the single table. After a RMAN restore into a TEST database you can also create a database link and copy the table into the target database using CTAS.
