Delete the subscription from the database?

  1. When do we actually delete the subscription from CPS DB ? We plan to do it when we receive response from the DMI plugins and the underlying subscriptions from the devices are deleted.

2What do we need to send to the DMI Plugin
  1. subscription name + client id
  2. + cmhandle ids?
  3. + cmhandle properties?
  4. + datastore?
