Abstract

See full text

A computer program product, system, and computer implemented method for management of a consolidated database and implementing pluggable database recovery with redo filtering in a consolidated database according to some embodiments. Generally, the process includes ongoing activities that maintain activity logs and summarize the activity for respective activity logs (e.g., in an activity vector maintained in a consolidated database catalog). In some embodiments, event-based activities corresponding to recovery processes are triggered by an administrator or an automated process, completed and then do not occur again until another triggering event. The event-based activities can leverage the summary information to quickly determine which online activity logs are relevant to the type of recovery operation for a particular pluggable database. In this way the approach provided herein enables recovery without requiring that all log activity be analyzed to determine whether it is relevant to a particular pluggable database.
