recoverActivity in the instance management API

[Thilina Gunarathne <cs...@gmail.com>]

Hi all,
I would like to know whether the recoverActivity operation in
InstanceManagement API is in working condition. Also what's the semantics of
it when invoked using "retry". Does it re executes the mentioned activity?
What will happen if the activity instance is already executing (eg: Invoke
activity waiting for a response)...

The operation requires the ActivityInstanceId to be given together with
ProcessInstanceID. How can I retrieve the ActivityInstance ID for an
activity.

thanks,
Thilina

Yes, it reexecutes the activity.

I have not tested this myself but you'll likely get an error because the
activity won't be in "activity recovery" state and thus I don't think it
will handle the request.   If it doesn't report an error, then we have a
bug.

By getting the instance detail information (TInstanceInfo) with all the
scopes and iterating through the scopes to find the activities that needs to
be retried.

There are some example in
bpel-runtime/src/test/java/org/apache/ode/bpel/runtime/ActivityRecoveryTest.java
