Abstract
Apparatus, methods, and computer code for monitoring a database and for detecting execution plan changes in the database. In the event that an execution plan is detected for a given database statement during the course of the monitoring, an alert signal may be generated. Optionally, the generation of the alert signal is further contingent upon a property of the database statement for which an execution plan change has been detected, for example, an execution time. In some embodiments, a detection agent is configured to repetitively attempt to detect an execution plan, for example, in accordance with a specified frequency parameter.
