Quest SQL Optimizer for Oracle Subscription, from Quest Software Inc., is a performance tuning solution that helps DBAs and developers quickly find, fix, and prevent inefficient SQL in Oracle environments. It identifies high‑cost statements, automatically generates semantically equivalent SQL alternatives, and tests them to surface the fastest options. Clear, visual execution plans and side‑by‑side comparisons of plans, statistics, and run times make it easy to validate improvements before deployment.
The tool supports batch optimization for large codebases, impact analysis to reduce production risk, and index analysis to explore indexing strategies without guesswork. What‑if testing with hints and optimizer settings, plus regression testing to confirm stability over time, streamlines ongoing performance management. It integrates with Toad for Oracle to fit smoothly into existing workflows and supports both on‑premises and cloud‑hosted Oracle databases.
The subscription provides continuous updates and technical support, helping you shorten tuning cycles, stabilize workloads, and maximize the performance and value of your Oracle infrastructure.
