Enrico Levesque updated ODE-483:
--------------------------------

    Attachment: bookshop-example-4.zip
                bookshop-example-1.zip

I added 2 project examples, deployment zip files and the soapUI xml projects to test the processes.  They are 2 versions of a bookshop example, the first one without correlation and the second with correlation.  I used those to test the Replayer, one all automatize and the second requires the response of a financial analyst.

The first one works fine with the Replayer, since there is no correlation.  The second works if the instance stop before the exchange that comes in asynchronously from FinancialAnalyst, but it doesn't retrieve the instance by correlation during replay if you try to replay the whole process after completion.

For the processes to work, you need to run the mock services inside SoapUI.  I just used SoapUI to send my messages from the interfaces provided.  Sorry I didn't take the time to setup a test case yet.

> Imagine situation when client has deployed a process with a lot of active, long running instances. Then he finds there's a bug in this process and a simple bugfix is needed. But with current versioning rules, new version is only used when new instances are created. So there's no simple way for doing such bufixes (which are usually possible with eg. java application using database connection). It is a blocking argument for deploying ODE Bpel solution instead of a regular java application.
> I think the best way to deal with such situations is to add serialize/deserialize to/from xml operations for process instances in management API. Also pause/resume ODE operations would be useful. 
> Then, a bugfix procedure would look like this;
> -pause ode
> -serialize instances
> -deploy newer version
> -deserialize instances and fix manually any import errors 
> -resume ODE
> It would also be a benefit of being able to do migration from older to newer ODE and between Hibernate/JPA DAOs, which I saw already in some bug reports. 
> What do you think about it?
