[Oslc-Automation] Complex automation tear down scenario for discussion

[David N Brauneis]

Michael,

I think the search criteria to determine if anyone is registered as 
interested in them is just as you indicate, recursive starting with the 
final piece and working back to the initial piece. I think there is 
possibly a sub-optimization in you example where if no one is registered 
as interested in the application server or database server, then rather 
than uninstalling the applications and database tables, then 
uninstalling/de-provisioning the application server and database it can 
all be accomplished by removing the application server and database 
server.

Regards,
David

In today's OSLC Automation workgroup there was some interesting discussion 
around deployment environments created by the execution of multiple 
automation plans orchestrated by a top-level/"master" plan.   When a 
consumer is finished with the environment it can request tear down, but 
what are the implications for the "sub-environments"?  We discussed an SAP 
landscape, but I think a generic enterprise application illustrates the 
issue as well:

- consumer requests deployment of the enterprise application environment 
via a top-level automation plan.   The top-level plan in turn runs 
automation plans to:
   - provision a virtual network
   - install and deploy a DB server
   - install and deploy an application server
   - install and configure an enterprise application and its DB

What is the correct behavior when the consumer indicates the environment 
is no longer required?  Recursive tear down of any environments which have 
no one registered as interested in them?


Regards,
Mike
