----------------------------------
Thanks very much, Jørgen. I'm working on the new topics for the Tuning Guide,
and I have a few more followup questions.
Which log are replication messages written to -- the derby.log file, or the
transaction log file that gets shipped from the master to the slave? I'm
guessing the derby.log file.
Also, just to clarify -- when you say "min <= (max/10)" does that mean that it
is the responsibility of the user to make sure that the min value is less than
or equal to a tenth of the max value? What would happen if the user set the
minLogShippingInterval to 2500 without also changing the
maxLogShippingInterval? I am guessing that this would be allowed but would
result in bad performance -- is that right?
Are these properties system-wide or database-wide, or can they be either? See
http://db.apache.org/derby/docs/dev/tuning/ctunproper51399.html for definitions
of these terms.
Are these properties dynamic or static? See
http://db.apache.org/derby/docs/dev/tuning/ctunsetprop824615.html for
definitions of these terms.
