how to use "per process instance" runtime strategy with Jbpm 6.4 in spring framework
Dear All,
I have a business process with multi instance human task subprocess. Basically, it is leave approval process where one or many person may be involve to approve an employee leave.
Here employee apply for leave for one or more people sign it to get task done.With Singleton strategy everything is running fine.Now I want to migrate it to "per process instance" runtime strategy. For that I modified code and added following code
| this.kieSession = this.runtimeManager.getRuntimeEngine(ProcessInstanceIdContext.get()).getKieSession(); |
|
I have following doubts:-
1. Is creation of Kie Session is required only at the time starting of process ?
2. How to extract process_instance_id for accessing kie session in future while signing the leave ?
3. What is best approach to solve the above problem ?
4. Is "per process instance" runtime strategy is enough or should I nee move to "per request" runtime strategy ?
5. What is exact difference between Singleton and "per process instance" runtime strategy ?
6. Which one should I use if I have around 200 simultaneous user accessing my application ?
Thanks and Regards
