Re[2]: OFA (Optimal Flexible Architecture) in practice

IMHO I think you all have got the reasons for OFA somewhat backwards. Back in the older days one had one and only one version of Oracle running on a particular machine at one time. This made upgrading/migrating or running a new version in test while the older one was still running production absolutely impossible or at least very difficult. The idea around OFA is that you have one or more Oracle home directories off of Oracle base and all of your data files elsewhere. Now when it comes time to upgrade you just shutdown, backup the datafile area, move a couple of init or cfg files, startup, run the scripts required, shutdown & backup the same directory(s) again.

Linda,

The point of OFA is to spread out the database over different drives for performance reasons. For example, you might want to separate indexes from data. Would what you are proposing allow for multiple drives?
