DB Optimizer Features

Listed product, feature, and database platform support varies based on product edition. For details, please visit the Product Editions tab.

General Features
Multi-platform Support Supports all major DBMSs from a single interface. Ability to use the tools on all supported platforms from a single license.
Embarcadero® AppWave™ Enables centralized license management and tool deployment
Unicode Offers full Unicode support
Command-Line API Launch profiling and tuning sessions remotely
Visual Diagnostics
Profile Chart Shows the CPU, I/O, and other wait activity over the course of the session. Zoom in/out functionality available. (Wait categories vary by platform.)
Execution Statistics Detailed information on the profiled SQL and wait categories, broken down by SQL statements, events, and sessions.
Profiling Details Drill down into the execution details for any given statement, including the SQL text, events, sessions, child cursors, blockers, procedures, and SQL details.
Predicate Analysis SQL statements are rolled up for a true analysis of the number of executions in real-time
Explain Plans The Explain Plan for each SQL statement can be computed on demand via a context menu item in the Execution Statistics table. The Explain Plan appears in a separate view as a tree with columns and collapsible column groups.
Cropping Highlights a time interval in the profile chart to instantly change the data displayed, making it easier to see the details.
Profiling
Sampling Identify and diagnose performance bottlenecks and problematic SQL without agents or placing a significant load on the target database.
Load Editor SQL stress testing simulates a number of parallel users and executions over a specific period of time or execution cycle.
Continuous Profiling Continuously profile an entire data source within a configurable span of time.
Profiling a Stored Routine When fine tuning or testing SQL, profile the execution of a single stored routine when profiling an entire data source is not desired.
Live Data Show data in real-time while profiling is in progress.
Sharing Profile Sessions All data and metadata pertaining to a profile session can be saved as a single entity into an archive file. Profiles can be shared across multiple workspaces and machines for collaboration purposes.
Tuning
Tuning Job Create and run tuning jobs for a single statement or batch of statements.
Batch Tuning Tune all DML statements, stored routines, and entire SQL files.
Case Generation SQL rewrites and hint injection are used to generate all possible cases and find the best alternative to a given SQL statement.
SQL Rewrites SQL rewrites are suggested as part of the case generation in the SQL tuner. SQL rewrites are also suggested as you type in the SQL IDE.
Hint Injection Customize the subset of hints to be considered for hint injection and alternative execution paths.
Cost Generation Display the explain plan cost for each original statement and each generated case to give the user the expected cost given the execution path utilized by the database.
Visual SQL Tuning The Visual SQL Tuning (VST) diagram displays indexes and constraints on tables and views, as well as the joins used in a SQL statement such as Cartesian joins, implied Cartesian joins and many-to-many relationships, with table statistics
Index Analysis The color-coded Index Analysis feature shows indexes that are used (green), not used (blue), or missing (orange) and offers indexing recommendations for optimum performance.
Execution Statistics Run the SQL with alternative execution paths to discover the fastest running SQL statement, and apply the change at the click of a button.
Textual Comparison of Cases A visual diff viewer helps the user spot the textual differences between any two SQL statements.
Data Capture
File Capture Save an entire profiling session to a file for future analysis and reference or to share with others
Repository Capture Stream profiling data into a central repository for your open session
