Abstract
Techniques are described herein for capturing and restoring database session state. Production database server components save the session state of each of a plurality of database sessions. The components store workload units that are processed in these sessions. The components store updated session states in response to certain events. Thus, the components may capture multiple session states, pertaining to various different points in time, for each session. The captured session states and the captured workload are moved to a test database server. A user selects, from among the time points represented by the session states, a point in time at which the user would like workload replay to begin. Sessions are re-created on the test database server. Session states of these sessions are set to reflect the session states as they existed at the user-selected time point. Workload units are replayed in the sessions relative to the test database server.
