Category Description
Dispatcher
System
Threads
BPEL
Service
Engine
This specifies the total number of threads used for
general cleanup tasks. A small number of threads are
required to handle the number of system dispatch
messages generated during runtime. The default value
is
2
.
Dispatcher
Invoke
Threads
BPEL
Service
Engine
This specifies the total number of threads allocated to
process invocation dispatcher messages. Improved
performance may be achieved by increasing the num-
ber of invoke threads, particularly if the majority of re-
quests are instance invocations (as opposed to in-
stance callbacks), However, higher thread counts may
cause greater CPU utilization. The default value is
20
.
Dispatcher
Engine
Threads
BPEL
Service
Engine
This specifies the total number of threads allocated to
process engine dispatcher messages and impact
activities that are processed asynchronously. Improved
performance may be achieved by increasing the num-
ber of engine threads, particularly if the majority of pro-
cesses are durable with a large number of dehydration
points (midprocess receive, onMessage, onAlarm, and
wait activities). However, higher thread counts may
cause greater CPU utilization. The default value is
30
.

and outgoing messages in the engine is performed.
