Abstract
The increasing complexity of database management systems (DBMSs) and their workloads means that manually managing their performance has become a difficult and time-consuming task. Autonomic computing systems have emerged as a promising approach to dealing with this complexity. Current DBMSs have begun to move in the direction of autonomic computing with the introduction of parameters that can be dynamically adjusted. A logical next step is the introduction of self-tuning technology to diagnose performance problems and to select the dynamic parameters that must be adjusted. We introduce a method for automatically diagnosing performance problems in DBMSs and then describe how this method can be incorporated into current DBMSs using the concept of reflection. We demonstrate the feasibility of our approach with a proof-of-concept implementation for DB2 universal database.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
