Streamline SQL Tuning Across Major DBMSs
Tune poorly performing SQL code on all major DBMSs (Oracle, SQL Server, DB2 and Sybase) from a single common interface. Reduce training requirements and streamline collaboration among teams across the organization.
Tune SQL Like a Pro!
The SQL tuning wizard automatically suggests solutions and provides essential context in tuning SQL code. Color-coded Index Analysis shows used, not used, or missing indexes and offers recommendations for optimum performance. Case Generation is used to generate all possible cases and to find the best alternative to a given SQL statement by including SQL rewrites and hint injections.
Visually Tackle Complex SQL Queries
Unique in the industry, Visual SQL Tuning (VST) diagrams turn text-based SQL code into graphical SQL diagrams. This approach helps DBAs and developers understand the impact of SQL statements on the database. The VST diagram displays indexes and constraints on tables and views with table statistics, as well as the joins used in a SQL statement such as Cartesian joins, implied Cartesian joins and many-to-many relationships.
Identify Performance Bottlenecks Immediately
Database profiling provides a graphical visualization of wait-time analysis, making the SQL that is causing poor database performance easy to pinpoint. Continuous profiling monitors an entire data source within a configurable span of time. Also, explain plans are provided for a better understanding of how SQL will be executed and the performance costs. Utilize reporting to allow sharing of information captured during the profiling process.
Simulate Production Environments
Load testing verifies performance of existing and alternative SQL queries against the database. Configure queries to run multiple times in parallel and see how they respond to your simulated production environment without the risk of actually testing in production.
Multi-Platform Tuning Interface
Automate SQL tuning across all major DBMSs (Oracle, SQL Server, DB2 and Sybase) from a single common interface, and use the tool on all supported platforms from a single license. Streamline and automate common and repetitive tasks with an easy-to use GUI and powerful wizards.
Create and run tuning jobs for a single statement or batch of statements. Tune all DML statements, stored routines and entire SQL files.
SQL Rewrites & Case Generation
SQL rewrites are suggested as part of the case generation in the SQL tuner as well as when you type in the SQL IDE. SQL rewrites and hint injection are used to generate all possible cases and find the best alternative to a given SQL statement.
Customize the subset of hints to be considered for hint injection and alternative execution paths.
Explain Plan Cost
View 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.
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.
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 difference viewer helps the user spot the textual differences between any two SQL statements.
Identify and diagnose performance bottlenecks and problematic SQL without agents or placing a significant load on the target database.
SQL stress testing simulates a number of parallel users and executions over a specific period of time or execution cycle.
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.
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.
View the CPU, I/O, and other wait activity over the course of the session. Zoom in/out functionality available.
Detailed information on the profiled SQL and wait categories, broken down by SQL statements, events, and sessions.
Drill down into the execution details for any given statement, including the SQL text, events, sessions, child cursors, blockers, procedures, and SQL details.
SQL statements are rolled up for a true analysis of the number of executions in real-time.
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.
Highlights a time interval in the profile chart to instantly change the data displayed, making it easier to see the details.
Stream profiling data into a central repository for your open session.
Save an entire profiling session to a file for future analysis and reference or to share with other teams in the organization.
