RE: OFA (Optimal Flexible Architecture) in practice

We used OFA with a small "modification"..

We used raw devices for the data files of the tablespaces. Then we built symbolic links to all of the necessary devices from a core directory. Those sym links were placed in a single directory off the $ORACLE_BASE.

For example, all of the sym links would be in the following: $ORACLE_BASE/links/<dbname>

It worked well for us... This may not fit the requirements of other shops...

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?
