Abstract
In an approach, a database server maintains a container database which comprises: one or more pluggable databases, a root database that stores an undo log for rolling back transactions on the consolidated database, and a redo log for replaying modifications to the container database. The database server restores a particular pluggable with a backup version that corresponds to a first point in time. The database server generates a clone database loaded with a backup version of the root database that corresponds to the first point in time. The database server applies the redo log to recover the particular pluggable database and the clone database to a second point in time that is later than the first point in time. The database server identifies, based on the clone database, one or more active transactions on the particular pluggable database. The database server rolls back the one or more active transactions.
