Thanks Ansdrew, We will get back to you before the meeting on Wednesday and we can discuss it in more detail at the meeting. Thank you very much for taking the time to summarize your expectations, it will go a long way towards clarifying how CDDLM can contribute to EMS. I am forwarding your email to the CDDLM mailing list. Best regards, Dejan

Dejan, et al,
There are two basic things that EMS needs (in my opinion): 1) The ability to identify on which hosts an activity can execute because either the executable for the activity is installed - or CAN BE installed. 2) The ability to direct that the necessary components for an activity be installed and configured in/on a container - whether that means binaries and libraries, licenses, databases, whatever.
In both cases I do not want the activity started.
Let me dive a bit deeper into both: 1) The information needed to determine where an activity can execute - either directly, or after some deployment step is needed by RSS so that it can make scheduling decisions. While it is not sufficient information to make scheduling decisions, it is necessary. (Other info could include load, whether a particular user has privileges or the necessary currency, etc.)
2) Once a placement decision has been made then we must ensure that the application/activity is ready to run on the selected container resource. In the current JSDL model - all of the information is carried in the executable information. For more interesting, non-legacy, components latter, it is likely that the mechanism in JSDL will not suffice. Thus, something like: Deploy("name of application/component", "name of container resource")
Where each of the "names" are either path names in a directory based service or EPR's of some sort.

Hi Andrew,
At Boston, you agreed to provide one paragraph describing your expectations from the deployment component. You have articulated it at that time. Using this paragraph, we'll provide a feedback on how we match your expectations.
Can you please provide this paragraph to us? This is in preparation for the OGSA meeting on 11/9 which CDDLM participants will join.
Thanks,
Dejan.
