Using the same definition for several decision engines
To reduce memory consumption, you can create several engines
for concurrent use from the same engine definition.
About this task
Creating several engines from one engine definition, instead of loading an engine definition to create each engine, reduces memory consumption. It does not degrade performance.
Rule Execution Server directly supports concurrent executions.
If you do not want to use Rule Execution Server, use an engine, as an Engine instance, in only one thread.
Do not use the same objects in different engines in different threads.
Procedure
To create several engines from the same definition, use
the following code:
EngineDefinition definition = ...
Engine engine1 = definition.createEngine();
Engine engine2 = definition.createEngine();
