Hi all,
I make cold backup for my database. I have scheduled backups of 11 p.m. every night and your database crashes at 11:30 a.m. in the morning.Because the latest backup I have is only of the previous night. So all the changes to the database from 11 p.m. to 11:30 a.m. will be lost.In order to avoid this, archived redo logs are backed up and they are coupled with the cold backups to provide recovery to the point of failure.

I have a cold backup at 11 p.m.
I have archived redo logs backup after 11 p.m.

But I don't know how to couple archived redo logs backup and cold backup together

Can anybody help me???????
thanks,

If your database is in archived log mode,
why are you doing a cold backup?

May be or may not be.
If you can afford to shutdown everyday , backup and bring them up online, you can go for it. But , this is a stone age method.
You are already have database in archived log mode ( That is like half-way through). Use RMAN.
You can incrementally backup along with archivedlogs/controlfile/spfile etc and even manage them easily.

may be you have no archived logs.
Post what you did. Else we have no idea what you are talking about. Login as sys and issue archived log list.
see whether you have archived log enable and automated on ( on contrary to what is shown here.)
Then check you archive destination.

sys@9i > archive log list
Database log mode              No Archive Mode
Automatic archival             Disabled
Archive destination            /u01/app/oracle/product/9.2.0/dbs/arch
Oldest online log sequence     68
Current log sequence           70

>>Automatic archival Disabled
You have to manually archive.
Google for it or refer documentation.

Restore the cold backup, and say "RECOVER DATABASE ...". Oracle will prompt you for the archived logs.
