We describe how to recover applications after system crashes using database recovery. Earlier efforts, based on frequent application checkpoints and/or logging values read, are very expensive. We treat application state as a cached object and log application execution as operations in the recovery framework of D. Lomet and M. Tuttle. Logging application execution does not require logging the application state. Further logged application reads are mostly logical operations in which only the data source identity is logged. We describe a cache manager that handles the flush order dependencies introduced by these log operations and a recovery process that restores application state by replaying the application.
