Incorrect. If the tuples smaller, Oracle does the right thing. If
there's enough space in the page, it shifts the tuples to make room.
That's what pctfree, pctused and pctincrease allow you to control.
It's all in

Hi guys,
This basically continues the other thread about the PERC4 RAID controller,

I have been searching (www.lsil.com) for this megaraid_2 driver you
mentioned.
What kind of MegaRaid card does the Perc4/Di match? Elite1600? Elite1650?
