What happens at server restart?

[bodi]

Hey,

What happens when a server is restarted after crash?
Will engine restart automatically ?
WIll aborded processes be restarted after server restart ?
Is server restartability after server crash, supported by engine

[winko]

No sadly not, you'll have to restart your database and web server manually:
ant h2.start tomcat.start

But is there any API or provision in Activiti to resume from last engine crash state ?

@Winko: Quite obvious you should start your container and DB again, don't think he was talking about that

Activiti supports recovery in case of error/restart by being a transactional state machine at the lowest level.
In case of error, the transaction will roll back to the previous consistent state, which is a wait state (eg a user task).

If Activiti crashes, the database will rollback the transaction that Activiti was executing, hence restoring the state of the business process to the previously stable state. If you are using Activiti in a persistent way (ie. if you are using the services http://activiti.org/userguide/index.html#N1023F, this is the behaviour of the engine).

That's done automatically. Activiti starts processing all remaining jobs in the database automatically.

Yes, I meant business process

Many thanks
