My sincere advice would be to include "BACKUP CURRENT CONTROLFILE" in
EVERY backup you make. Also, turn the autobackup on. If you ever happen
to lose an entire machine and have to use SET DBID, you will have to
restore controlfile from autobackup.
The usual setup is to run data backup on standby only and to run the
archive log backup on both primary and standby database, in order to
maintain the free space and a running database. Nasty things happen when
the database cannot write an archive log because the log destination is
full. And those nasty things usually happen around 3 AM.

Good afternoon. Thanks so much for all valuable advice. Do I backup control file on the standby or primary if I want to activate the database restored using backup from standby? I added the following command to my script on standby database: BACKUP CURRENT CONTROLFILE;--
Thanks in advance,
Vadim

However they say "fast" incremental backups. What does it
mean exactly? BCT file usage on Standby:

Didn't know that.

Incremental backup from an active Standby is under ADG

But it doesn’t say database is Read-Only with Real Time
Apply.
So for me incremental backups from “Active” mean applying
changes is under ADG licence.

Backup from standby database
Any proof link for that? ADG has appeared in 11g while
backups from standby are available for a long time - do
you mean there was a license agreement change? I highly
doubt so.

Hi Vadim,
Remember that you must be licensed active data guard
for backup from active standby. Cheers Jko

Good evening oracle experts. I am having issue
activating database restored using backup taken
from standby.
Our current setup: We have one primary and
one standby database. The standby database is
kept in sync with primary using dataguard. We are
currently taking backups from primary. We are
want to move backups from primary to standby
database.
I used script bellow to take backup from standby
database and then restored backup on different
server. The database was successfully restored
and physical standby. The problem started when I
try activating it. I got the following error
ORA-01194: file 1 needs more recovery to be
consistent
ORA-01110: data file 1:
'+STAGEDATA/SETLR/DATAFILE/system.5096.929468439'
I will greatly appreciate suggestions on taking
backups from standby in order to restore as
primary in case of emergency as well as how to
solve inconsistency error after standby database
is activated.
Thanks so much,
Vadim
