Hey all,

We're well on our way to implementing a new ERP system in 10.2.0.2.0 on
AIX 5.3.  One thing I've noticed is that while the redo logs are ~50MB,
the archived redo logs from "regular" log switches are consistently only
~45MB.  On 9.2.0.5 on HPUX, our 90MB redos tend to switch with 2K free.

Not that this affects a whole lot in my planning, but I'm just curious.
Trapsing through the admin docs doesn't seem to mention anything other
than the minimum size of a log is 4MB.

Thoughts anyone?  And if you have definitive info, where from?

TIA,
Rich
