Hi Joel,
Correct me if I am wrong, but I believe there is nothing about management has
been published by SCA spec group. At this time, it is hard to define what
exactlly "SCA knowledge" is. JBI defines five Management Beans, to do the tasks
like deployment, component lifecycle management, component
installation/uninstallation etc. I think we can safely presume that SCA
management will need to do sth similar as well. As long as those
functionalities have been implemented by runtime and captured by
CommonManagement model, it should be relatively straightforward to expose those
managment capbilities from CommonManagement model to different protocols (snmp,
jmx, WSDM) and different management models(SCA, JBI or WSDM). For example, lets
presume that SCA management spec is published and it is similar to JBI, I would
imagine the CommonManagement model will be very much as the
JMXManagedComponentManager model, except CommonManagement model is not directly
depending on JMX (i.e., not using MBeanServer as registry and Mbean as metadata
entities). However, it is very likely that the mapping between
CommonManagement model and "WSDMManagedComponentManageer model" is not a direct
one to one mapping.
To support WSDM, we need to figure out what kind of Tuscany management
interfaces are required by WSDM. On the other hand, we also need to know when
the SCA management is going to be published by spec group and what it looks
like. I will also post this thread to Tuscany mailing list so someone may want
to comment on Tuscany side.
Cheers,
Jervis Liu

No worries. Yes, minutes are posted, but we decided to talk about SCA
week after next (6/30) since you weren’t there and I’m on vacation next week.
The good news there is that Mark Weitzel can sit in on the call – he know much
more about WSDM that I do, so we can probably have a much more detailed
conversation.
I looked at the link you sent (to the Celtix design), and it looked
pretty straightforward. My one question/concern would be how much SCA knowledge
is contained in the JMXManagedComponentManager vs. the CommonManagement model.
The diagram seems to imply that the SCA Management facility is constructed out
of parts from the Common model, but isn’t present in the Common model. If
that’s the case, then we should probably discuss how to commonize that, as I’m
sure a WSDM implementation would require those same interfaces.
Look forward to talking to you in a couple of weeks!
Joel
