The normal method is to copy out the days worth of archive log file as part
of your normal backup routine. Then maybe keep 2 days worth on-line so that
they are available for a recovery without getting them back from tape.
Keep a watch on the disk space to ensure that the disk does not get full and
a new archived redo log cannot be created.

Hi Hallas and All DBAs
Thank you for your advise.
I have a question if I turn on our archive redo log do I
need to copy out
that archive log frequently ?

FOR YOUR INFORMATION
ESIS and EPFAL are now part of Logica. The Internet email
addresses of the
staff has changed to the following -
[EMAIL PROTECTED] eg
[EMAIL PROTECTED] Emails using the old format will continue
to be delivered
until 30th June 2001.
With no disrespect to your English, the phrase "weakly copy
of dbf files"
(rather than weekly) seems rather appropriate.
As several other listers have stated, by far the best option
is to enable
archive logging.
Whilst you seem to have the bases covered, have you
considered how long it
will take to re-apply the batch files and whilst there may
not be much
online input you are running the risk of losing all data
that has been
input after your last export and before the next one.
Best advice seems to be try archive logging and identify the
impact then
make a considered judgement.

db corrected
Currently the application insert data from
batch localy and
a bit from
online insertion. We have clustering for our
database.
noarchive, I do export tables after run
batch (daily),
weakly copy out all
dbf files and ctl and redo log files. and
copy them to tape.
It's that true once the redo log switch,
oracle will write
redo log changes
to dbf ?
Do you have any recomendation for better
backup strategy ?

Sinardy,
Who will recover the database in case of a
failure?
Turing on archiving would not hinder
performance so much.
Proper planning of your backup strategy and
db setup will
have little
overhead
on performance of your database.
You cannot sacrifice backups for a marginal
increase in
performance
especially if
your db is a high transaction processing
system.
Regards
Suhen
The developer application running huge batch
inserting data
into database,
that is what they told me, if you are me
what you will do?

assuming you're the dba, since when does the
developer
dictate
recoverability to a DBA about a database.
sounds like a role problem there.
