Are you starting EAE service when you are configuring the activity engine database?
Once you are into Activity Engine Database setup screen, run below commands in terminal:
Yes activity engine already started.
Since set up workig for local jive DB so issue related with DB dump. I think we need to clear some activity DB related entries from DB dump but not sure of these tables.
Maybe try this: Steps for Moving Data to Lower Environments (Prod to Dev)
Also with EAE it sometimes starts (as does local search) but with errors and only appears to be running. Take a look and make sure it is properly starting.
