Benchmark Factory for Database 8.4 - User Guide

SQL Scalability Testing from Toad

Note: To run SQL Scalability testing from Toad you must have Benchmark Factory installed. The Benchmark Factory console does not have to be open to run SQL Scalability testing.

Overview

The SQL Scalability test allows you to execute SQL statements, letting users spot potential issues not seen with a single execution. Users can run variations of a SQL statement generated by SQL Tuning in order to find the SQL that will perform the best under a load test.

Creating a SQL Scalability load scenario requires the following steps.

1. Creating the SQL tuning connection
2. Entering the desired SQL statement
3. Running the statement using the Benchmark Factory SQL Scalability testing

Creating the SQL tuning connection

To create the SQL Turning connection

1. In Quest Central or Toad for Oracle, connect to an Oracle or SQL Server database.
2. From the Quest Central main toolbar select Tools|SQL Tuning to launch.

Entering the desired SQL statement

To enter the desired SQL statement

1. Enter the desired SQL statement in SQL Text.
