Abstract: Embodiments store transaction metadata in dedicated pools of allocated memory chunks. Portions of the pools of allocated memory chunks are dedicated to the respective apply slave processes that mine and process change records. Also, the pools of allocated memory chunks are anchored within the structure of a transaction log such that buffering and application of metadata for one transaction does not block required buffering and application of metadata for other transactions. The standby database system pre-processes transaction metadata in preparation for application of the metadata to invalidate appropriate portions of MF data. Further, embodiments divide the work of pre-processing invalidation records among the many apply slave processes that record the invalidation records. A garbage collection selects memory chunks for garbage collection in reverse order of how the chunks were allocated.

Abstract: A vehicle includes a frame, a subframe, a powertrain, a steering gear, and a bracket. The subframe is fastened to the frame at a subframe attachment point, and the subframe is movable relative to the frame along a collision path in response to a frontal collision. The powertrain is attached to the subframe. The steering gear is coupled to the subframe and disposed in the collision path between the powertrain and the subframe attachment point. The bracket is attached to the powertrain and disposed in the collision path between the powertrain and the steering gear. The bracket is positioned to wedge the steering gear between the subframe and the frame during the frontal collision to deform the subframe at the subframe attachment point.

Abstract: A vehicle includes a vehicle body that includes a rocker fixed to an underbody. The rocker and the under body at least in part define a front wheel well of the vehicle. A rim engagement member is cantilevered from the underbody and extends into the wheel well. The rim engagement member snags a rim of a front wheel of the vehicle and directs movement of a front wheel of the vehicle away from intrusion into a floor and/or dash of the vehicle.
