Figure 91. Configuring memory checker thread properties Further considerations Consider the following information when using the memory checker thread: v You should not use the memory checker thread if you are running an InterChange Server Express instance that processes few transactions. For instance, if you have the -mx parameter set to less than 512 megabytes, the Java Virtual Machine garbage collection thread will not be able to free memory effectively. v Use the following techniques to determine the best configuration for the memory checker thread properties: - Initially, set the Memory lower threshold percent and Memory upper threshold percent properties close to one another, test the behavior of the system, then increase the difference between the values and test the system again. Repeat this process to determine the optimal difference. - Set the Connector pause time at threshold property between one and five minutes. - If InterChange Server Express must handle a heavy workload, set the Memory checker sleep time property to a small number so that it takes more frequent measurements and regulatory actions. 284 IBM WebSphere Business Integration Server Express and Express Plus: System Implementation Guide

Further
considerations
Consider
the
following
information
when
using
the
memory
checker
thread:
v
You
should
not
use
the
memory
checker
thread
if
you
are
running
an
InterChange
Server
Express
instance
that
processes
few
transactions.
For
instance,
if
you
have
the
-mx
parameter
set
to
less
than
512
megabytes,
the
Java
Virtual
Machine
garbage
collection
thread
will
not
be
able
to
free
memory
effectively.
v
Use
the
following
techniques
to
determine
the
best
configuration
for
the
memory
checker
thread
properties:
Initially,
set
the
Memory
lower
threshold
percent
and
Memory
upper
threshold
percent
properties
close
to
one
another,
test
the
behavior
of
the
system,
then
increase
the
difference
between
the
values
and
test
the
system
again.
Repeat
this
process
to
determine
the
optimal
difference.
Set
the
Connector
pause
time
at
threshold
property
between
one
and
five
minutes.
If
InterChange
Server
Express
must
handle
a
heavy
workload,
set
the
Memory
checker
sleep
time
property
to
a
small
number
so
that
it
takes
more
frequent
measurements
and
regulatory
actions.
