---------------------------------------------------------------
Hi all,
I was able to run the Replayer on my own processes but with some modifications
as explained earlier, but the processes need to be RUNNING IN MEMORY.
I added this fix to BpelRuntimeContextImpl.getCurrentEventDateTime() :
was -
public Date getCurrentEventDateTime() {
return _currentEventDateTime;
}
changed to -
public Date getCurrentEventDateTime() {
if (_currentEventDateTime == null)
return Calendar.getInstance().getTime();
else
return _currentEventDateTime;
}
This other fix to invoke(...) in the same class :
was -
...
MessageExchangeDAO mexDao = _dao.getConnection().createMessageExchange(
MessageExchangeDAO.DIR_BPEL_INVOKES_PARTNERROLE);
mexDao.setStatus(MessageExchange.Status.NEW.toString());
mexDao.setOperation(operation.getName());
...
changed to -
MessageExchangeDAO mexDao = _dao.getConnection().createMessageExchange(
MessageExchangeDAO.DIR_BPEL_INVOKES_PARTNERROLE);
/* modif enrico */
mexDao.setCreateTime(getCurrentEventDateTime());
mexDao.setStatus(MessageExchange.Status.NEW.toString());
mexDao.setOperation(operation.getName());
This fix to PartnerLinkMyRoleImpl.invoke(...) :
was -
mex.setCorrelationStatus(MyRoleMessageExchange.CorrelationStatus.CREATE_INSTANCE);
mex.getDAO().setInstance(newInstance);
instance.execute();
changed to -
mex.setCorrelationStatus(MyRoleMessageExchange.CorrelationStatus.CREATE_INSTANCE);
mex.getDAO().setInstance(newInstance);
/* modif enrico
* createTime needs to be initialized for getCommunication in Replayer*/
if (mex.getDAO().getCreateTime() == null)
mex.getDAO().setCreateTime(instance.getCurrentEventDateTime());
instance.execute();
And into invokeInstance(...) of the same class :
was -
mex.setCorrelationStatus(MyRoleMessageExchange.CorrelationStatus.MATCHED);
mex.getDAO().setInstance(routing.messageRoute.getTargetInstance());
instance.execute();
changed to -
mex.setCorrelationStatus(MyRoleMessageExchange.CorrelationStatus.MATCHED);
mex.getDAO().setInstance(routing.messageRoute.getTargetInstance());
/* modif enrico
* if createTime need to be initialized */
if (mex.getDAO().getCreateTime() == null)
mex.getDAO().setCreateTime(instance.getCurrentEventDateTime());
instance.execute();
I also did two other fix but I never verified if they where necessary.
ASSIGN
public Date getCurrentEventDateTime() {
/* enrico modif */
//return null;
return Calendar.getInstance().getTime();
}
PropertyAliasEvaluationContext
public Date getCurrentEventDateTime() {
/* enrico modif */
return Calendar.getInstance().getTime();
//return null;
}
These where necessary so we can use getCommunication on instances created
without the Replayer.
replayInstances works again but only when processes are executed in memory.

> Issue Type: New Feature

> Attachments: Khriss-AdaptabilitySupport.pdf, replayer-example.zip,

> 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?
