Although MCPD may default to 700centiseconds [although I have seen a much
lower value on 9.2 on Tru64],
in most cases, delays of 7seconds don't occur [and shouldn't be
acceptable ?!].
I do have a 9iRAC environment but am comfortably using mcpd=0.
And I have AQ in an 8.1.7 single-instance

You
are right. 7 seconds is the MAX difference, but the control files are
synced
every
3 seconds during the 'split brain' check. So most of the cases, it is 3
seconds
with
the maximum of 7 seconds subject to the MCPD settings.
