Re: upper limit on extents

If I'm understanding the admin guide, what you say doesn't make sense.
Because basically the number of extra extents boils down to the frcnt output divided by 8 that is obtained by doing an oncheck -pP of different parts of the Physical Address.
I quickly tried that forumula manually on 2 different tables and got two totally different numbers.

As all fragments have to use the same page size, they all have the
same max number of extents. You only need to find one.
