Tosska DB Ace Enterprise is a premium SQL optimization solution targeting DBAs managing mission-critical Oracle and SQL Server databases. Pricing ranges from $9,990-$19,990 depending on database edition and licensing. The platform provides unique capabilities including optimization without source code changes (using SQL Patches, Plan Baselines, Stored Outlines), DB Link SQL optimization for distributed databases, and performance prediction before implementing changes. Supports Oracle 11g through 21c and SQL Server 2012+. Key differentiators include the ability to tune third-party application SQL without modifying code, automatic testing of multiple execution plans, and comprehensive what-if analysis. The tool generates SQL Profiles, SQL Plan Baselines, and SQL Patches that Oracle’s optimizer will use without application changes—critical for commercial applications where source modification isn’t possible. Page should cover: Oracle-specific vs SQL Server-specific capabilities, optimization without code changes methodology, DB Link optimization, pricing justification for enterprise, comparison with native Oracle tuning tools, and use cases for third-party application optimization.
