Gene - Perhaps someone on the list has directly tried this. It is
theoretically possible to get a good backup on a quiet but open database
with just a cold backup, but not the sort of thing you want to bet your job
on. One idea would be for you to take your backup and restore it on a test
system. It is always a good practice to test your database restore anyway.
Then you would be assured throughout the year that you do indeed have a
valid backup. But I would do it each year since there might be some
condition that would make the backup succeed 50% of the time, you would be
covered all the time.

Subject: RE: Archive Mode On for Read Only DB
Dennis - The database is opened in read only mode. The database changes once a yr to be updated w/ new images. At that time, I put the db in read write mode, add the images, then open db in read only and back it up while db is open. It is a web query db that I would like to minimize down time. Is there any benefit to putting this db in archive log mode? I don't see any, but I may be missing something :).
Thanks for your help,
Gene

Gene - By read only, do you mean the contents of the database are never
changing? Do you ever take it out of read only mode, like to change
something? Why back it up occasionally? Just do a cold backup once and save
the tapes.

Subject: Archive Mode On for Read Only DB
I have an 8i read only database that is used for query of images. Occassionally, I back it up using OS utilities (cp, tar, TSM, etc) while the db is open.
Question: Is there any benefit to having this db in archive log mode? Since it is in read only mode, I see no benefit or am I missing something?
Thanks for any insight you may provide,
Gene
