What's the objective of that question? I mean, those tables are internal to the engine and they will be used by the engine as needed. If you want to extract information about your rules and process executions you can configure the History Logs to extract the information that you need in the schemas that best suit for you.
dear Mauricio thanks for your answer,
but I want to know when this table will be used by engine, or when engine will fill data to this table.
(maybe when an event occures?)
nothing to say to help me?
I examined all the events and all the node types in jbpm. But this table doesn't seem to be used by engine.
Maybe this table is no longer used by engine and previous versions of jbpm were using this table.
Doing a quick search in the latest source code it looks like is not used anymore.. it is probably legacy code that needs to be removed, because no other entity reference it.
Yes you are right, I think so.
Thanks for help dear Mauricio.
