SQL Optimizer for Oracle 9.3.4.1759 Enterprise (x86/x64)

SQL Optimizer also provides a complete index optimization and plan change analysis solution. It provides index recommendations for multiple SQL statements or a SQL workload, simulates index impact analysis, and generates SQL execution plan alternatives.
SQL Optimizer consists of the following modules:
Optimize SQL
Optimize SQL includes a SQL Rewrite mode and a Plan Control mode.
Optimize Indexes
Optimize Indexes analyzes a SQL workload or any group of SQL statements and determines the best index set for the workload or group of statements.
Batch Optimize SQL
Batch Optimize submits files, database objects, or SQL text for batch processing. Batch Optimize scans and extracts the SQL statements, optimizes the statements, and tests the alternatives to find the best performing SQL statements for your database environment.
Scan SQL
Scan SQL identifies problematic SQL statements in your source code and database objects without execution. Scan SQL then analyzes the problematic SQL statements and categorizes them according to performance levels.
Inspect SGA
Inspect SGA analyzes SQL statements from Oracle's SGA. You can specify the criteria used to retrieve SQL statements and execution statistics to review SQL performance.
Analyze Impact
Use Analyze Impact to evaluate the impact on a SQL workload from database changes by tracking execution plan and Oracle cost changes for SQL statements. You can run an impact analysis to estimate the performance impacts from parameter changes and new indexing. You can also run a comparison of two different databases that run the same application.
Manage Plans
Manage Plans organizes stored baselines and outlines used to improve SQL statement performance.
