Activiti Concurrent running Issue

[mdjuned]

Hi ,

I have a web app where in I am using activiti work flow to  call a webservice , we're hitting a bpmn file with multiple configurations with multiple users , so any  login user can concurrently change bpmn properties and run the workflow.

Now if i simulate 50  concurrency  user via Jmeter then I am getting following exception , this output is profiled via yourkit profiler.

My process Engine code is like this :

ProcessInstance processInstance = processEngine.getRuntimeService()
.startProcessInstanceByKey(testCaseSpecificBean.getWorkflowKey(), variableMap);
‍‍‍‍‍

After googling i figured that  i have to  set StrongUuid in order to solve the problem , if its correct ,then how would i set StrongUuidGenerator in the processInstance instanse ?

Hi,
you can set a new idGenerator like that:
<code>
       <bean id="processEngineConfiguration"  class="….">
 
  <property name="idGenerator">
   <bean class="org.activiti.engine.impl.persistence.StrongUuidGenerator" />
  </property>

</bean>
