Hi Ed,
As Mark and Andrew have said you really should think about getting some
help or training if possible. If anything happens it will be your ass on
the line. You may succeed in getting the backups up and running but
recovering the database is a whole other story. Darl Kuhns RMAN recipe book
helped me a lot at the start.

This sounds like pretty good advice, Andrew. The OP might also want to
think about hiring a consultant -- maybe a business consultant -- to help
work out both the *goals* of a business continuance plan and the
*implementation
*of one.
So far, the original question sounds a lot like "I would like to build my
own automobile. I have been told that steel is a good material, but I
don't know much about it and I don't yet know where to obtain any. Can you
help..."
The fact of the matter here is that I *can* help in this case, as -- most
likely -- can most of the other people frequenting this list. But the
question is far too broad and the subject far too complex to even attempt
to address by e-mail. Of course, even if I could, I probably wouldn't,
since answering questions like this is how I normally earn my living. :-)
Ed, you might find it helpful to look over the backup and recovery
"concepts" manual. After you have read this, you will probably have most
of the knowledge that the reference manual assumes you to have. Taking a 3
day course is probably a good idea, though, anyway.

In your case, my best advice is to take one of the 3 day oracle backup
and recovery courses. You will really need a better understanding than we
can give just by answering your questions here. Once you take the course,
build your own instances and experiment.

Hi
I’m trying to develop DR plans for an application we run that’s built on
top of Oracle. According to what I’ve read, RMAN is the recommendation.
After going through the RMAN docs a couple of times, I still feel I don’t
know enough to actually make a plan to depend on, so I’m hoping someone can
put me on the right path without too much bother.
The app is not very busy by any standards that might come up here. It
supports a liquid handling system that mixes a bunch of solutions together
and then periodically over the next month or so takes pictures. The DB is
used to keep track of all that from entry to exit from the system. The
pictures are stored as a filename, so the picture files themselves also
have to be backed up. At the moment, the plan is run RMAN incrementals
daily from the AT queue to a USB disk. The picture files should be
discoverable through some SQL, though I can envision a way to find them
with a shell script (ugh!).
I think I want to use a catalog because the changes are kept in the
recovery area. I’m confused between archive-redo logs, control files, the
catalog, snapshot files, the RMAN copy command, and what constitutes all
the info necessary for the backup to be able to be restored. The manual
feels like it assumes I know way more than I do, so I don’t feel I know
enough to make the decisions here. Would someone please let me know what is
really necessary? Is a catalog really the best way to go?
The manual talks about RMAN not being able to work across platforms, but
I can’t seem to find the definition of a platform. Since this is on Server
2003, it’s going to be wiped and reloaded (probably 2008 – 32 bit), so I’m
hoping I can use this to restore the data once that happens. Will that work?
In trying to make the initial backup in preparation for turning the
archive log on, the shutdown immediate command (wouldn’t transactional be
better?) works great, but startup mount (as told in the manual) fails with
error ORA-12505 TNS: Listener could not resolve SID given in connect
descriptor, so it takes a reboot to get everything back in line. Somewhere
in the myriad readings I ran into this, but I can no longer find the
answer. How do I bring it up correctly without having to reboot?
Is there any way to create something to test with? I only have one shot
at this and would really like to get some experience under my belt before I
need it.
Many thanks!!!
Ed Hoeffner
