Ive got a script that i used to run in 8i that shows me the rbs wraps, waits, extents and whatever, and i had certain things i looked for like waits and wraps, and i used that to add rbs or grow rbs etc...

Im using auto undo in 9i now, but when i run my old scripts I show wraps in the undo headers that would indicate, i think, that i need larger rbs, since the only rbs left is the mandatory system rbs...

are any of these stats relevant now? when using auto undo, is there any need to "tune" the remaining system rbs?

any comments would be appreciated...
