Oracle storage parameters – next extent size and max extents

pts.

I am looking for a general rule for determining the optimal setting for next extent size and max extents for oracle tables in an existing database. Specifically, is there some sort of formula that helps approximate the best values? Up to now I have been using best guess based on the size of the table and how fast it is growing.

You did not indicate Oracle version. If 8i or higher, you should be using LMTs (locally managed tablespaces) and stop worrying about next extent sizes and max extents. Group tables by function and average size and set up locally managed tablespaces with uniform extent size (in 8i) for small, medium and large. Put the tables in these tablespaces and you don’t worry about calculating individual table storage parameters ever again.
