Thank you ALL for your responses. Rachel, I quoted exactly what the
documentation says. It is in oracle 8i backup and recovery training doc by
oracle. It is on page 43 of 12th chapter. That is why I was confused and
seeking some suggestions.
Since our system is data warehouse system, we decided to run in noarchive
log mode. All we care is, restoring the last backup. From the business
point of view, It is okay to see the data as of last backup (that is
previous day) and repopulate current day's data. We do not want to take
the burden of running in archive log mode.
Having said this (please see my earlier mail down below for the questions I
asked),
1. Are the incremental backups are valid which are done when the database
is in mount state?
2. Since I want to keep the db open while doing rman backups, I wanted to
open the db in archive log mode during backups(backup including archive
logs) just for the sake of backups. Do you think the backups are not good
for restore.
Thanks in advance for your help.
Best regards,
Prasad

Please
respond to
ORACLE-L
the documentation told you: no they are not
just because the incremental backup completed does not mean that it is
usable.
Either leave the database in archivelog mode to do incremental backups
or keep it in noarchivelog mode (and why you would not want to do that
is a whole other discussion) and do full backups
