    false ping
    Перевод ложная выгрузка из кеша
    Описание V$FALSE_PING is an Oracle9i Real Application Clusters view. This view displays buffers that may be getting false pings. Occurs when you down-convert a lock element which protects two or more blocks that are concurrently updated from different nodes. Assume that each node is updating a different block. In this event, each node must write its own copy of the block, even though the other node is not updating it. This is necessary because the same lock covers both blocks.
