OTS11 — Failure recovery in Additional Structuring Mechanisms for OTS

  • Key: OTS11-2
  • Legacy Issue Number: 5452
  • Status: open  
  • Source: Red Hat ( Mark Little)
  • Summary:

    The current specification has the necessary hooks for recreating the
    distributed activity tree in the event of failures, but the text does not
    give an implementers view of what to do. For example, when using
    interposition, it is somehow necessary for a SubordinateSignalSet to
    remember who (ActivityCoordinator) it was enlisted with so that, upon
    failure and recovery, it could enquire as to the status of the activity.
    Now, since a SubordinateSignalSet is also a SignalSet, there is a
    set_activity_coordinator method that the enroller of the
    SubordinateSignalSet could use to pass the reference to it. The
    SubordinateSignalSet can then persist this information when (and if) it is
    necessary during the protocol. When it recovers, because all IORs are
    required to be persistent, it will be able to contact the coordinator and
    find out the status.

    Some text like the above would be very useful in the spec.
