wso2 - wso2bps 3.6.0 async tasks -


i need create parallel running service tasks in process.

try create simplest flow async property usage:

enter image description here

with loop cardinality = 5 (for example)

i found in activiti.xml configuration it's required add property:

    <property name="asyncexecutoractivate" value="true" />

but flow still runs in 1 thread.

what i'm missing?

how activate async correctly?

  1. to activate async parallel execution in example above - need set async on call service , not on sub process

  2. as use async have configure process engine async

    otherwise meet king of exception:

    org.activiti.engine.activitioptimisticlockingexception: variableinstanceentity[id=15317, name=nrofactiveinstances, type=integer, longvalue=1, textvalue=1] updated transaction concurrently

    the parameters of activiti engine on wso2bps stored here: conf/activiti.xml

    just add following properties bean id="processengineconfiguration" 

    <bean id="processengineconfiguration" class="org.activiti.engine.impl.cfg.standaloneprocessengineconfiguration">    ...    <property name="asyncexecutoractivate" value="true" />    <property name="asyncexecutorenabled" value="true" />    ... </bean>

    warn: don't know if it's feature or bug. subprocess catch correctly thread endings if set async on end events of subprocess...

after changes, process question works great in multithread mode.
