[Exist-open] eXist Crash Recovery questions

[Adiarto P. <ad...@gm...>]

Hi,

I have some questions to clarify my understanding about eXist recovery:

Assuming I have recovery enabled,

- When there is power outage when eXist is running (dirty shutdown), on the next
time exist is turned on, will the recovery process started automatically based
on the log?
- Is there any way to trigger the recovery process manually? e.g. when we notice
that there is a corruption on the data..
- Assuming this case: I am running a long update query (around 10 minutes) that
adds a new tag/attribute in ~4000 documents in a collection. In the middle of
the query (while it's running), there is power outage.
When eXist is turned on the next time, what is the expected behavior/result in
the db? Will (1) some of the documents get updated and some not, or will (2)
exist rollback everything in the query as if it didn't happen?
I have tried to simulate this case on current developent trunk's exist (1 month
old from now) - and I got the first case (1). Is this the expected behavior?

Thanks,
Adi
