Easy answer.  Separate box for testing, integration testing, etc.  OS
upgrades are going to affect everyone so it's a one time push.



As far as Oracle upgrades, I can install multiple versions of Oracle on the
same box (wow, imagine that), have databases pointing to specific versions
for usage, and then migrate back to a common version when all upgrades are
complete.  It's in the planning and the proper implementation.



Thank You

Stephen,



Out of curiosity, how do you deal with application testing (or for that
matter compatibility) when upgrading the Oracle version?

I have a different way of justifying it.  It seems that everyone still
assumes the one application = one database mentality.  I have chosen to
implement a different strategy.  Multiple applications = one database.  I
see no reason to use the "file server" approach anymore.  The issues with
downtime, etc. outages are easily managed and performance is not squandered
if the equipment is properly configured.



So, your tact could be that larger disks can be used by multiple
applications in a single database for better and more efficient utilization
of resources.



Thank You

I'm curious as to how others with smaller  databases deal with it as  well..




You can't even buy under 18GB hard disks for some brands of servers
anymore..


My production databases are all relatively small  i.e.  5 GB - 7 GB, but yet
I'd still want several independent physical disks to spread the I/O load...



On test servers,  the 'extra' space is easy to justify because you often
create several instances


for different purposes...  But on your production box it can seem a bit
excessive.



I justify it in part by  pointing to the increased flexibility afforded..
e.g.  you could do cold backups to disk in minutes and then copy the backed
up


     files to tape after the database is restarted.

Hi,



I was wondering how DBAs are coping with these new large disks that are
available....you can purchase 36gb, 72gb, etc. You can fit a whole database
on one of these. But with all the performance and redundancy
considerations, you wouldn't....so what do you do with the free space? Or
how do you tell your bean counter that out of that 72gb you are only going
to use 10gb so you need a couple of these?
