SQLパフォーマンス・アナライザの結果を別のテスト・システムに保存する
After you have captured the SQL workload into a SQL tuning set on the production system, you can conduct SQL Performance Analyzer analysis on the same database where the workload was captured or on a different database. Because the analysis is resource-intensive, it is recommended that you capture the workload on a production database and transport it to a separate test database where the analysis can be performed. To do so, export the SQL tuning set from the production system and import it into a separate system where the system change will be tested.
You can run the SQL Performance Analyzer on a test system that closely resembles the production system, or on the production system itself. Performing a SQL Performance Analyzer analysis is resource-intensive, so performing the analysis on the production system may cause significant performance degradation.
The Global Statistics section reports statistics that describe the overall performance of the entire SQL workload. This section is a very important part of the SQL Performance Analyzer analysis because it reports on the impact of the system change on the overall performance of the SQL workload. Use the information in this section to understand the tendency of the workload performance, and determine how the workload performance will be affected by the system change.
To run SQL Performance Analyzer, you must first create a SQL Performance Analyzer task. A task is a container that encapsulates all of the data about a complete SQL Performance Analyzer analysis. A SQL Performance Analyzer analysis comprises of at least two SQL trials and a comparison. A SQL trial encapsulates the execution performance of a SQL tuning set under specific environmental conditions and represents a particular test execution or explain plan operation performed by SQL Performance Analyzer when testing a system change. When creating a SQL Performance Analyzer task, you will need to select a SQL tuning set as its input source. The SQL tuning set remains constant in the SQL Performance Analyzer task and is executed in isolation during each SQL trial. Thus, performance differences between trials are caused by environmental differences.

When creating a SQL Performance Analyzer task, you will need to select a SQL tuning set as its input source. When building SQL trials using the test execute or explain plan methods, the SQL tuning set will be used as the source for SQL SQL Performance Analyzer analysis will show the impact of the environmental differences between the two trials.
Once you have captured a SQL workload that you want to analyze into a SQL tuning set, you can run SQL Performance Analyzer to analyze the effects of a system change on SQL performance. To run SQL Performance Analyzer, you must first create a SQL Performance Analyzer task. A task is a container that encapsulates all of the data about a complete SQL Performance Analyzer analysis. A SQL Performance Analyzer analysis comprises of at least two SQL trials and a comparison. A SQL trial captures the execution performance of a SQL tuning set under specific environmental conditions and can be generated automatically using SQL Performance Analyzer by one of the following methods
