Not ready for 11G yet. Trying to move from 9i to 10G. The problem is
with the 3rd party applications we have, some are just being certified for
10G.
I had the feeling that bigfiles is not such a good idea. We use rman for
our oltp applications, but not for the datawarehouse.
Thanks to all that have responded!
Thank you
Ana

Re: Question on bigfiles
Honestly, if your going to use BIGFILES I'd go 11gR1 instead, particularity
if you are using RMAN.

We're configuring a 10G test database. Version 10.2.0.4 on Red Hat
Enterprise Linux Server release 5.4. Normally we do exports to backup the
data, and there is a backup server that backs up the entire server. Because
is our datawarehouse database we're in noarchive log mode.
One of our tablespaces is about 80 GB.
I have a test 10g database already with bigfiles, but whenever I want to
look at the tablespaces either on Database Control, or the Enterprise
Manager console it takes a while to see the results. This database is on
Solaris 10. I'm not sure if performance might be an issue with bigfiles, or
if the slow response is related to the OS.
Thank you
Ana

Re:Question on
bigfiles
Ana,
many pros/cons can be O.S. related, which is your version for Oracle and
O.S.? What is the backup type you use?
As a first caveat, backup may be an issue, some tape drives (not too
updated, indeed) may not handle > 2Gb files.
