Paralel process

My process has two sequential parallel called processes. A Q&A session followed by voting. My understanding is that in this case each execution thread gets its own process and a copy of the business data. This seems to work as long as each execution thread only adds data and does not update data which causes StaleObjectExceptions.

Hi ,
how i create 2 or more process and when user have started a sesion , retrieve all the HumanTasks that user have.?

Is it possible have parallel proceses?

Regards
