Alignment of Physical Stripe Boundaries with Block Size Boundaries
LausMay 23 2013 — edited May 24 2013Hi,
I was recently asked a simple question that I couldn't answare with certainty.
If your stripe depth is the same size as the database block, then a single I/O
issued by Oracle Database may result in two physical I/O operations. The question was: Why this MAY or MAY NOT happen?
I was thinking. Is there something (metadata or some header) in internal stripe structure, more precisely structure of ASM extent or AU, that require part of available space dedicated to database block data, or is it someting else?
Thx in advance for all answares.
