Under the SQL Query Plans will be analyzed section, select the options for retrieving your query plan.
- Using existing query plan saved with the SQL
This option uses the query plan that was saved with the SQL statement at the time that statement was saved to the SQL Repository, or scanned in the SQL Scanner.- Obtaining a new query plan under the current connection
This option retrieves the query plan with the current database logon. This current query plan is compared to the query plan that is retrieved after executing the configuration changes.
Select to view the configuration parameters for the various options within Adaptive Server.
Make any parameter changes by inserting a value in the New Value column.
Click Finish to perform the analysis.
After the analysis, you can see the overall results by clicking the Analyzer, and its related information, in the tree structure in the left pane and viewing the corresponding information in the panes to the right.
In the right pane for the Scenarios, click Prognosis to see overall performance changes and SQL details.
The Migration Analyzer helps you to preempt performance degradation when performing database migrations, upgrades, and application rollouts. It ensures reliable database performance by tracking query plan and cost changes. You have an option to integrate abstract plan management to help stabilize SQL performance during migrations.

Selecting the segment for the index scenario to be created in and the number of consumers.
If the Index Impact Analysis was called from the Index Advisor, the index scenarios are automatically display and you can choose the index scenarios to include for analysis.
To manually add indexes click .
Give the index a name for easy reference.
In the Index based on section of this page, specify in which database to create this index and specify the owner to use, and then specify the table that contains the column(s) to include in the index.
The columns of the table display in the Table columns page and can be selected to use in the index scenario, under the Index columns page, by double clicking them or using the right arrow button.
Specify the Index type by checking the option to have the index Unique and whether to create the index as Clustered or NonClustered.
Click OK to perform the Index Impact Analysis.
Note: The indexes are physically created in the database, and then the query plans for the selected SQL statements are retrieved. After the query plan retrieval, the indexes are dropped.

The Index Usage Analyzer identifies unused indexes by analyzing query plans from SQL statements in your database applications. It examines their query plans and reports any indexes in the database that are not used. You can use this module to quickly identify the indexes in databases that are not contributing to the performance of the database applications These unused indexes can then be deleted to free up space and improve the speed of the database applications and maintenance.
