Alter database open resetlogs - why

2881781Jan 20 2017 — edited Jan 26 2017

Hello All,

Its pretty common question which all DBA's have an answer. I know what it does not but what I find to hard to understand is as follows.

If I have to restore database using an rman online full backup (oracle documentation says - rman online backups are inconsistent )

it asks for more archive ( RMAN-060504 - media recovery )  , sometimes it even prompts you to keep on applying the archived redo logs

to make your database consistent. Is there any way/method/views using which you can restore db without having to open database

with resetlogs using only online full backups.

Few other questions what I have are as follows.

1) how does it actually decides when to make the database consistent ?

2) what best I can do to avoid or not having to use ''Alter database open resetlogs " .with full online backups only.

Thanks

Mohammed
