Field / Description
Tuning Formula or Default Value
(Default value is provided if there is no
tuning formula)
Number of Processor Cores
Number of processor cores in the system,
where each core is an independent
processing engine.
tuning.properties Property:
PROCESSORS
Not Applicable
Desired Global Threads
Number of active business processes that
can run concurrently. This field changes the
JMS_LISTNERS property in the
tuning.properties file in the
install_dir/properties directory.
Typically, you require higher values with
more CPUs, and lower values with fewer
CPUs. Too many threads cause thrashing, in
which the hard disk is used a lot for virtual
memory, and performance slows down.
tuning.properties Property:
JMS_LISTNERS
JMS_LISTNERS = (PROCESSORS * 4)
In memory cache size (MB) for small
contexts
Amount of memory allocated to the business
process queue. After Sterling B2B Integrator
reaches this limit, it writes all the messages,
except active messages, to disk. This field
changes the JMS_PAGING_HIGH property
in the tuning.properties file in the
install_dir/properties directory.
Increasing this value too much reduces the
amount of memory available for the other
components of Sterling B2B Integrator, such
as caches and general processing.
tuning.properties Property:
NOAPP.JMS_PAGING_HIGH
NOAPP.JMS_PAGING_HIGH = 100
